Common Process Industry Safety StandardsMoore Industries Functional Safety Series Products

Left to Right:STA SIL 3 Capable Safety Alarm Trip or Transmitter,SRM SIL 2 Capable Safety Relay Repeater and SSX/SST SIL 3 Capable Safety HART Isolators/Splitters Architectural Constraints - Limitations imposed on the components and architecture selected for implementation of

a safety instrumented function (SIF), regardless of the performance calculated for a subsystem in terms of failure rates i.e.PFDAVG. Each SIL requires the element/device to meet Safe Failure Fraction (SFF) and minimum degrees of fault tolerance (HFT) dependent on the device type. (see “Architectural Constraints” table at left under )

Beta Factor (ß) - The percent of the failures for a specifi ed device that are attributed to common cause failure modes.

CCF - Common Cause Failures are applicable to safety instrumented systems that are composed of redundant discrete modules in which single failures impact multiple parts of a system, such as a common input; a design, manufacturing, or software error in identical modules; systemic failures caused by human error in system design, operation, or maintenance. The CCF is derived by performing a diversity and experience analysis on the hardware, software and the engineers. The analysis then results in two beta factors, β and βD. The beta factors, which are usually expressed as percentages, are applied to the portion of the system that is vulnerable to common cause failures.

DC - Diagnostic Coverage indicates the proportion of dangerous failures that are detected by the device using diagnostic techniques. Expressed in the equation DC = λDD/λD, DC is multiplied by the number of dangerous failures (D) to obtain the proportion of dangerous detected (DD) failures; the remainder of the dangerous failures is considered to be dangerous undetected (DU).

Demand Mode - Defi nes how often the system will be expected to operate its safety function. • Low Demand Mode: the safety function is only performed on demand and the frequency of demands is no greater than one per year.• High Demand Mode: the frequency of demands for operation made on a safety related system is greater than one per year.• Continuous Mode: the safety function maintains the system in a safe state as part of normal operation.

FIT - Failure In Time is a unit measure for failures, indicating one failure per 1,000,000,000 (109) hours.

FMEDA - Failure Modes, Effects and Diagnostic Analysis is a systematic way to identify and evaluate the effects of different component failure modes, to determine what could eliminate or reduce the chance of failure. The FMEDA report identifi es the overall hardware (random) failure rates of a device (λ) and also specifi es PFDAVG/PFH, SFF, HFT, MTBF, T1 and Proof Tests.

HAZOP - A HAZard and OPerability Study is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment, or prevent effi cient operation. A HAZOP is a qualitative technique based on guide-words and is carried out by a multi-disciplinary team (HAZOP team) during a set of meetings.

HFT - Hardware Fault Tolerance is the ability of a functional unit to continue to perform a required function in the presence of faults or errors. Most single devices have an HFT=0. Together with the safe failure fraction, this fi gure is used to deter-mine the highest safety integrity level that can be claimed for the safety function according to the architectural constraints.

MTBF - Mean Time Between Failures is the predicted elapsed time between failures of a system during operation. It is calculated as the arithmetic average time between failures of a system. MTBF=MTTF + MTTR

MTTF - Mean Time To Failure represents the average time to failures of a system.

MTTR - Mean Time To Repair represents the average time required to repair a failed component or device.

PES - Programmable Electronic System is a generic term used for computer based systems.

PFDAVG or Average Probability of Dangerous Failure on Demand - Calculated for each Safety Instrumented Function (SIF) used in a low demand mode of operation and is one of the factors in determining the maximum Safety Integrity Level (SIL).

PFH - Or Average Frequency of a Dangerous Failure per Hour. Calculated for each Safety Instrumented Function (SIF) used in a high demand or continuous mode of operation and is one of the factors determining the maximum Safety Integrity Level (SIL).

PHA - Process Hazard Analysis/Evaluation is a set of organized and systematic assessments of the potential hazards associated with an industrial process. A PHA is directed toward analyzing potential causes and consequences of fi res, explosions, releases of toxic or fl ammable chemicals and major spills of hazardous chemicals, and it focuses on equipment, instrumentation, utilities, human actions, and external factors that might impact the process.

Proof Test - Exposes dangerous faults that are not detected by internal diagnostic tests of a Safety System (ie. dangerous undetected faults). Most proof tests do not cover 100% of faults so after each proof test the accumulated PFDAVG value is reduced to a smaller but nonzero value.

Proven In Use (Prior Use) - For legacy devices, it may be possible to use a Proven In Use argument as an alternative to meeting the design requirements for dealing with systematic failure causes in IEC 61508, including hardware and software. It is essential to note that Proven In Use cannot be used as an alternative to meeting the requirements for failure rates and architectural constraints. The IEC 61511 standard may also allow a reduction in the required level of Hardware Fault Tolerance for fi eld equipment when the equipment can be deemed Proven In Use.

RRF - Risk Reduction Factor is the number of times the risk is reduced as a result of applying a safety function. Defi ned as 1/PFDAVG for low demand and 1/PFH for high demand mode systems.

Safety Availability - The availability of an SIS to perform the task for which it was designed, presented in percentage (%).

SFF - Safe Failure Fraction is the ratio of the failure rates of safe plus dangerous detected failures and safe plus dangerous failures. Since edition 2.0 of the 61508 standard, the SFF defi nition was updated to explicitly exclude failures of any components which are not part of the safety path (no part failures) or failures which have no effect on the safety function (no effect failures). (see “Safe Failure Fraction SFF” table at left under for equations)

SIF - Safety Instrumented Function is the specifi c control function performed by an SIS. It is implemented as part of an overall risk reduction strategy.

SIL - Safety Integrity Level is a discrete level (1 to 4) for specifying the safety integrity requirements of the safety functions to be allocated to the safety-related systems, where SIL 4 has the highest level of safety integrity and SIL 1 has the lowest. This means that a SIL is related to the reliability with which the safety function will work as and when demanded.

SIS - Safety Instrumented System consists of an engineered set of hardware and software controls which are especially used on critical process systems. An SIS is engineered to perform “specifi c control functions” to failsafe or maintain safe operation of a process when unacceptable or dangerous conditions occur. An SIS must be independent from all other control systems that control the same equipment in order to ensure SIS functionality is not compromised.

SLC - Safety Life Cycle is the series of phases from initiation and specifi cations of safety requirements, covering design and development of safety features in a safety-critical system, and ending in decommissioning of that system.

Spurious Trip - A failure of the system which causes a process or fault trip when no actual trip conditions are present. Also known as a nuisance trip, it implies a failure of the instrumentation or safety system, but one that places the system in a safe state.

SC - Systematic Capability of an element is a measure expressed on a scale of SC1 to SC4 indicating the confi dence that the systematic safety integrity meets the requirements of the corresponding SIL (1 to 4). The SC level is based on the level of documentation and quality process used throughout the product’s development and is determined by compliance to the requirements for the avoidance and control of systematic faults per IEC 61508.

T1 - The Proof Test Interval is a defi ned period of time between proof tests. The interval is determined by the user according to operational considerations. A short Proof Test Interval will contribute to a higher SIL but could add to operational costs and process down time. Extend a Proof Test Interval too long and the rated SIL will be further restricted.

Type A Element - Used to categorize a ‘simple’ element/device where the failure behavior can be completely determined, such as an analog instrument.

Type B Element - Used to categorize a ‘complex’ element/device where the failure behavior cannot be completely determined, such as a processor based instrument.

DeviceSIL Capability

2SILac

3SILsc

Device SIL CapabilityAfter assessing these three factors the device’s SIL Capability for aSIF is based on the lowest of the SILsc, SILac or SILpfd. For example, if SILpfd and SILac meet SIL 3 but the SILsc is SIL 2 then the device can only be applied in SIFs up to SIL 2.

Device Selection via Proven In UseWhen instruments do not have SIL capable certifi cation the onus is on you, the end user, to justify the equipment for the SIF. You must assess the three SIL criteria covered here, and your device use justifi cation needs to be made based on Proven In Use data and assessment of the device manufacturer’s quality management and confi guration management systems. You must also verify that the Proven In Use data is drawn from similar applications and environmental conditions.

Device Selection Process for Your SIFTo determine whether an approved device can meet the required SIL for use in a SIF, there are three factors which must be assessed to arrive at a fi nal device SIL Capability:

-Probability of Failure on Demand (SILpfd). -Architectural Constraint (SILac).

-Systematic Capability (SILsc).

Information to determine these SIL capabilities can be found in the IEC 61508 approved device’s safety certifi cate and FMEDA report.

FOR REVIEW

New Approval from exida Adds SIL 3-Capable Product to Moore Industries’ FS Functional Safety Series

NORTH HILLS, CA—The SSX and SST family of safety isolators and splitters from Moore Industries have been approved by exida for use in a Safety Instrumented System (SIS) up to SIL 3 in monitor mode, where only the input circuit is part of the safety function. It is the latest product in the FS Functional Safety Series to receive SIL 3 approval, joining the STA Safety Trip Alarm. The SSX and SST are also approved for single use in an SIS up to SIL 2, as is the SRM Safety Relay Module. These three products form the core of Moore Industries’ line of safety-related instrumentation. They have been designed and built to strict IEC 61508 standards, ensuring safe and reliable function in all circumstances – particularly in environments where hazardous or emergency situations are likely to occur. Detailed FMEDA reports are also available for all FS Functional Safety Series Products. Although using Proven In Use data is an acceptable approach per the IEC 61508 standard, designing instruments in accordance with the standard from the ground up forces the components and circuit design to undergo additional scrutiny that ensures the highest level of reliability. Leading third-party safety auditing firm exida audits Moore Industries products and processes to ensure they are in compliance with the IEC 61508 standard. With this certification, end users can rely on FS Functional Safety Series instruments to perform as expected and when demanded. FS Functional Safety Series instruments are just some of Moore Industries’ products that are appropriate for safety applications. FMEDA reports are available for many of Moore Industries’ instrumentation products commonly used in safety-related settings.

Frequently Asked Questions for the Functional Safety Series What products are part of the Functional Safety Series, and what sets them apart from the other products? Our Functional Safety products were designed and built from the ground up in compliance with IEC 61508 specifications and third-party approved, certified for designated SIL level capability:

STA 4-Wire Programmable Current/Voltage and RTD/Thermocouple Safety Trip Alarms, and Temperature Transmitter, SIL 3 capable

SSX 2-Wire, Loop-Powered HART Safety Series Isolators, SIL 3 capable SST 4-Wire, Line-(Mains) Powered HART Safety Series Isolator and Splitter, SIL 3 capable SRM Safety Relay Module, SIL 2 capable

Why does this matter?

When products are designed in accordance with the standard from the ground up, the components and circuit design undergo additional scrutiny to ensure the highest reliability. In addition we have a third-party safety firm, exida, audit our product and process to ensure that the product and our processes are in compliance with the IEC 61508 standard.

Some competitors claim IEC 61508 compliance based on "Proven in Use" data. While this is an acceptable approach per the IEC 61508 standard, it often uses MTTF data that is derived from calculating successful operating hours by units shipped. This of course assumes that any units that failed in the field were immediately returned and documented by the supplier.

Will there be any more products coming to expand that series? Yes, we have products in development now, and plan a continuing expansion of the series to give your customers increasing number of solutions to apply to their safety instrumented systems.

Until the new products are released, are there any other products I can sell that will work in a safety instrumented system? Yes. We have several products, although not designed and built to IEC 61508 standards, which can be applied by an end user in safety instrumented systems following IEC 61511 standards using our rigorous FMEDA reports. Products with complete FMEDA documentation include:

CPA 4-Wire PC-Programmable Current and Voltage; RTD and Thermocouple Limit Alarm Trip CPT Isolated 4-Wire Site-Programmable Temperature Transmitter and Signal

Isolator/Converter ECT 2 and 4-Wire Signal Isolator/Converter HIM HART® Interface Module HIX 2-Wire HART® Isolator IPT2 DIN-Style Current-to-Pressure Transmitters

What is the IEC 61511 standard used for? The IEC 61511 standard: Functional safety –Safety instrumented systems for the process industry sector is an international standard that addresses the application of safety instrumented systems for the process Industries. It also requires a process hazard and risk assessment to be carried out to enable the specification for safety instrumented systems to be derived. Why is it important to customers to use a third-party certified product in their SIS? First, the third-party certification of a product to IEC 61508 specifications for SIL level capability gives the end-user engineer assurance that the instrument has the pedigree for application in an SIS, and has all the documentation to back it up. Second, when an accident occurs in a process plant with hazardous conditions, the burden of proof that rigorous engineering discipline was employed to prevent and accident rests solely on the plant and the safety engineer or process engineer responsible for the control system or safety loop that is under investigation. This responsibility is very serious and judgments from investigations can result in civil liability, enormous fines, and even criminal convictions when fault is found. Instrumentation designed and built to IEC 61508 specification with third-party certification removes much of that burden from the end-user because the certification proves the rigorous standards were applied and verified in development of the instrument itself. Without the third-party certification, they will have to do far more paperwork to implement an instrument in their safety loop or SIS, and far still in the event of an accident and investigation. While the certification does not totally remove their responsibilities and liability, using a third-party certified product saves them both time and money, as well as helping to ensure the safety of their people, process, plant and environment. You just introduced the SSX and SST, why are you sending out this release on the Functional Safety Series again so soon? Functional Safety is becoming increasingly important for the process industry with hazardous conditions and materials. We want to ensure you know that we have a full complement of instruments for safety applications, and that our commitment is to increase the availability of safety related products. What titles would these customers have? Many of the people implementing SIS (Safety Instrumented Systems) are the same people who we currently sell our ECT, HIX, HIT isolators, splitters and instrumentation to. For those facilities which choose to designate a particular individual or team of people with the task of implementing and maintaining the SIS within the facility, these would be the same ones who buy our Functional Safety Series products. A good place to start is by asking the question of: “Who in your plant is responsible for overseeing or implementing safety instrumented systems or safety loops?” Other buzzwords to drop are IEC 61511, IEC 61508, and S84, all of which are standards that revolve around safety and safety instrumented systems for the process control industries.

Page 8: 2013 FS Safety Family Release - PEI-FRANCE.com · Common Process Industry Safety Standards Moore Industries Functional Safety Series Products Left to Right: STA SIL 3 Capable Safety

What safety information would customers need when implementing an FS Series instrument? There are several pieces of information that a customer would need when implementing a component into a loop that is performing a SIF (Safety Instrumented Function). The most important of which are the SFF (Safety Failure Fraction) number, PFDAVG (Probability of Failure upon Demand Avg.), Proof Test Interval, and restrictions in use. The SFF, PFDAVG, and Proof Test Interval can be found in the instrument’s FMEDA report along with other important data that will be used in their safety calculations. The restrictions in use data can be found in the each product’s user manual. Can any of the Functional Safety instruments be used in normal (non-safety) instrument loops? Yes. All of them can be used just like a non-safety instrument. Do third-party safety approvals have anything to do with hazardous area approvals? No. Hazardous area approvals and safety approvals on products have nothing to do with one another. Once a safety approval has been granted for a product, it then has to be submitted to a separate list of companies that will then test the unit for hazardous area certifications. Many of my customers ask for SIL 2 transmitters. Are all of our safety products SIL 2? First, products themselves cannot be given an individual SIL rating. Rather a SIF (Safety Instrumented Function) will be given a SIL level. Then all products that participate in that SIF must meet the SIL requirements. Products will typically be given a “SIL Capability” rating defining to what level the product may be applied.

FS Functional Safety Series Family Talking Points

A short list of statements summarizing issues involving the product and explanation of important features/capabilities. FS Functional Safety Series product family is comprised of the:

o STA Safety Trip Alarm/Temperature Transmitter o SRM Safety Relay Module o SSX 2-Wire Signal Isolator/Converter o SST 4-Wire Signal Isolator/Converter and Splitter

Safety certification for the four Functional Safety products: o All are designed, and built according to IEC 61508:2010 specifications; verified and approved by third-

party auditor exida certified to these SIL capabilities: STA: SIL 3 capable in redundant architectures and SIL 2 capable in single use architectures SSX and SST: SIL 3 when only the input circuits are part of the SIF (Safety Instrumented Function);

SIL 2 capable when input and output circuit is used in the SIF. SRM: SIL 2 capable

o FMEDA reports for each are reviewed and endorsed by exida and can be provided upon request. FMEDA reports are specific to hardware and firmware versions, therefore FMEDA reports are sent upon request so customers always have the latest version.

Third-party safety verified and approved certification is a better alternative than Proven-in-use: o Proven-in-use relies upon documented field-based failure rate and reliability data. While this approach

is an acceptable method, it puts a tremendous documentation onus on the end user to prove that the application where the product is being used is similar to the documented proven-in-use history that the customer has on file.

o Products that are designed and built in compliance with IEC 61508 from the start and verified by a third-party auditor provide customers a reliable product with the required safety documentation.
