3.Demonstration/Tests

3.1.Purpose The ASR that will be supplied by the Contractor to the I.E.Co. will be participating in

an “Unreliability Field Demonstration” (UFD), in order to verify if they do not stand

the MTBF declared by the Contractor. I.E.Co.. will accept the ASR, only after

successful completion of the UFD (when the test ended with ACCEPT decision).

Bidder Reaction:

3.2.Principles 3.2.1.I.E.Co. will prepare the UFD Plan for the ASR and implement it. The calendar

UFD time will be 5 years. No relevant failures should be allowed. In case of 1 (one)

or more relevant failures that occurred during the UFD, the UFD will be ended with a

REJECT decision.

Bidder Reaction:

6 of 9


3.2.2.The Contractor does not have to invest any resources to the UFD, except to

participate in the FRB However, the Contractor shall assume full responsibility to the

results and the consequences of the UFD. For the purpose of the UFD, the

Contractor should:

- Use suitable design to meet specifications.

- Select proper components, and parts.

- Use proper production processes.

- Apply rigorous Quality Control procedures.

Bidder Reaction:

3.2.3.Getting a “REJECT” result in the UFD will be considered as Contractor’s

noncompliance with the ASR specification.

Bidder Reaction:

3.3.Penalties

If the UFD is terminated in “Reject” decision, Contractor will expend his Warranty

Period for failures to a total period of ten (10) years. In such a case the Contractor will

assume full responsibility for direct repair/replace costs attributed to failures since the

beginning of the Warranty Period, without any cost to I.E.Co. whatsoever.

Bidder Reaction:

4.RMS Definitions The following definitions are valid for all Reliability, Maintainability and Safety (RMS)

purposes in the specification for the Arc Suppression Reactor. The RMS parameters

are characteristics of the ASR design and production only, when they are properly

used and maintained.

(1) Failure A Failure is any event where an ASR ceased functioning, or functions outside of

its specification limits, and requires a repair/replacement.

(2) Non Relevant Failure A Non-Relevant failure for the purpose of the Failure Review Board (FRB) is a

failure that was classified by the FRB as such failure caused by:

7 of 9


- Bad handling, storage, transportation, or installation in I.E.Co.

- Test Equipment.

- External Force like: lightning, earthquake, abnormal storm, etc.

- Sabotage, or terror.

(3) Relevant Failure A relevant failure for the purpose of the UFD is any failure that could happen in

real life, but could not be characterized as “non-relevant”.

(4) Failure Review Board A Failure Review Board (FRB) is the only official, and authorized body entitled to

decide about failure matters, especially about failure classification as “Relevant",

or "Non Relevant”, to the UFD, The Contractor will be represented in the FRB.

(5) Design Defect Design Defect is a defect in an ASR that results from inadequate/error in the

design process. It may stay latent for some time, causing later a Systematic

Failure.

(6) Failure Rate

The failure rate, λ of an ASR is the number of failures per operating time unit.

(7) MTBF

MTBF is the mean operating time between failures of ASR. MTBF = 1/λ.

(8) Reliability Reliability is a design characteristic defining the ability of an ASR to perform

satisfactorily. Therefore: ASR reliability is the probability that an ASR will perform

without failures, for a pre-defined period of time, when used under stated

conditions (in I.E.Co.’s customer site). MTBF is a reliability parameter.

(9) Life Length The life length of an ASR is the time until the accumulated repair cost sum up to

the half of the price of a new one.

(10) Maintenance Maintenance is any action taken by technical staff to:

- Restore a faulty item to its operable condition after a failure, or:

- Preserve the operable, or safety condition of a good item, or:

- Test the operable condition of an item.

(11) Maintenance Levels (echelons) - Level “O” (Organizational): Performed on the ASR at I.E.Co. site by I.E.Co.

technical staff.

8 of 9


- Level “I” (Intermediate): Performed on the ASR at I.E.Co. shop by I.E.Co.

technical staff close to the installation site of the ASR.

- Level “D” (Depot): Performed on the ASR at Contractor’s shop for execution of

complicated repairs, or maintenance, that couldn’t be performed at “O”, or “I”

Levels.

(12) Corrective Maintenance Corrective Maintenance (CM), or repair, is the maintenance action carried out on

an item of the ASR, after failure recognition, and intended to put the item back into

a state in which it can perform again its required function satisfactorily, (during the

UFD no failures are allowed).

(13) Preventive Maintenance

Preventive Maintenance (PM) is the maintenance actions carried out on a good

item, at predetermined intervals, or in accordance with prescribed criteria, and

intended to reduce the probability of a future failure, or degradation of the

functioning of the item.

(14) Maintenance Policy Maintenance Policy is a description of the interrelationship between the

maintenance levels (echelons), the indenture levels of the ASR, the levels of

maintenance to be applied for the ASR’s, and the required resources.

(15) MTTR MTTR is the mean time required to perform a repair (including checks) or replace

of an ASR. The MTTR is given for the maintenance O, and I levels.

(16) Maintainability Maintainability is a design characteristic defining the ability of an ASR to be

restored quickly to its operable condition after a failure. Therefore, ASR

maintainability is the probability that a failed ASR is restored to its functioning

condition, within specified period of time, under stated condition, using stated

procedures (defined by the Contractor), and resources (defined by the I.E.Co.).

MTTR is a maintainability parameter.
