POLICY
The Cameron Division of Cooper Cameron Corporation supports the
development and use of international product standards such as those
published by API and ISO. These standards provide a common basis for
product characteristics and performance attributes and act to capture
the successful industry history associated with these products. Products
marketed, designed, manufactured and used in compliance with
recognized industry standards add significant value to our industry.
Cameron endorses the API monogram program and API Quality Program
Specification Q1. API Q1 applies the recognized benefits of the ISO 9001
Quality Program elements tailored specifically to the oil and gas industry.
The API monogram program joins the assessment of Quality programs
with the demonstrated ability to comply with international product
standards such as API Specification 6A (ISO 10423) for Wellhead and
Six pressure ratings from 2,000 to 20,000 psi represent the maximumworking pressure of the equipment.

Eight Temperature Classes, each of which represent a range oftemperatures from the minimum ambient air temperature to themaximum temperature of the well fluid passing through or contained by the equipment.

Note: These temperature classes can be used in combination with one another to achieve a wider rating. Forinstance, a common rating for 6A gate valves is P+U (-20 to 250° F).
There are seven Material Classes which specify minimum materialrequirements for general or sour service shown below. API 6A (ISO 10423) equipment must be designed, tested and marked assatisfactory for one of these Material Classes.
aAs defined by National Association of Corrosion Engineers (NACE) Standard MR0175bIn compliance with NACE Standard MR0175Only the most stringent classification is marked.
ANNEX F TESTING
Performance verification testing is often performed on prototypes orproduction models of API Specification 6A (ISO 10423) equipment toensure that the performance requirements (PR’s) specified for pressure,temperature, load, mechanical cycles, and standard test fluids are met in the design of the product.
Performance Verification Testing may include:Pressure/Temperature CyclesLoad/Mechanical CyclesNonmetallic Seal Thermochemical Testing
Scalable Performance Verification levels (i.e. PR1, PR2) are applicable tomany API 6A products. Although Annex F Testing is not a requirement inAPI 6A, Cameron is proud to offer a wide variety of products proven tomeet, and often exceed the performance verification requirements of API 6A Annex F.
Quality control requirements for welding generally increase as the PSLlevel increases from 1 through 3 with each level building on the levelbelow it. No welding is permitted on PSL-4 equipment except for corrosion resistant alloy overlays. The following table applies topressure containing fabrication and repair weldments for bodies,bonnets, and end and outlet connections:

Specification 6A (ISO 10423) describes pertinent information oninspections, tests, examinations, and required documentation. Since theselection of Product Specification Level (PSL) is ultimately a purchaser’sdecision, quality control information is provided to make it easy for usersto select the PSL level consistent with their risk management needs.

Definitions:
End and Outlet Connections - Integral threads, male or female; flanges, studded or through-bolted; or anyother means used to join together equipment that contains or controls pressure.
Body - Any portion of API Spec 6A equipment between end connections, with or without internal parts,which contains well-bore pressure.
Bonnet - A pressure-containing closure for a body, other than an API end or outlet connection.
MARKINGS
Section 8 of Specification 6A and the chart below describemarking instructions for equipment. The marking requirementsinclude the following:
OVERVIEWAPI Q1 is intended to be used in conjunction with international oil and gasproduct standards by internationally licensed manufacturers. Used in thismanner, API Q1 delivers significant value to the industry by providing acohesive link between the accreditation of a manufacturer’s quality systemwith their ability to provide products meeting industry and customerrequirements.
API Specification Q1 differs from generic quality systems, (e.g., ISO 9000Series), by its role in the voluntary licensing of manufacturers to provide oiland gas industry products in accordance with API specifications. API licensesare only issued after an on-site survey has confirmed that the licensee adheresto the requirements of both the quality system standard API Q1 and therequirements of an international oil and gas product specification recognizedby the oil and gas industry and API. In contrast, generic quality systemrequirements are normally intended to be applied to any industry or productthrough contractual agreements with or without industry standards orspecifications.
