This standard applies to equipment manufactured to editions of API 6A in which a product specifcation level (PSL) identifes the quality, material, and testing requirements for a specifc product. Equipment identifed as manufactured in conformance with API 6A prior to April 1986 (API 6A, 15th Edition) is outside the scope of this document. This standard is not applicable to onsite repair at the equipment installation site. 2 Normative References The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies, except that new editions may be used on issue and shall become mandatory upon the effective date specifed by the publisher or six months from the date of the revision (where no effective date is specifed).

Terms,? Defnitions? and? Abbreviated 3.1? Terms? and? Defnitions For the purposes of this standard, the terms and defnitions given in API 6A and the following shall apply.
4.4 Service Conditions The API 6A service conditions shall apply to equipment that is repaired/remanufactured to this standard. NOTE The service conditions include pressure ratings, temperature ratings, and material class ratings. 5 Design Requirements 5.1 General A documented procedure to plan and control the product defnition of the repaired or remanufactured parts, used or reused parts, and new equipment shall be maintained by the organization performing the repair or remanufacture. 5.2? Product? Defnition Product defnition shall conform to API 18LCM, Section 5.3.1.2, including any additional design verifcation and validation requirements per API 6A for the product in repair or remanufacture. NOTE Design validation may be done by an organization other than the repairer/remanufacturer. 5.3? Product? Defnition? Status If the product defnition cannot be established from the markings on the equipment and records that are traceable to those markings, the equipment shall not fall within the scope of this document and cannot be repaired/ remanufactured to the requirements of this standard. 5.4? Product? Defnition? Changes When repair or remanufacture of the product impacts the product defnition and the performance established by the original technical specifcation, the new product defnition shall be developed in conformance with 5.2. The changes to the product defnition shall conform to the requirements defned in API 18LCM, Section 6. NOTE Changes to product defnition can impact requirements for repair/remanufacture activities. 5.5? Product? Defnition? Documentation Records of product defnition shall include the following: ― design inputs, including user/purchaser requirements; ― design outputs, including drawings and relevant acceptance criteria; ― evidence of design review and verifcation; and ― evidence of design validation. Records of product defnition shall be maintained by the repairer/remanufacturer for 10 years after repair or remanufacture.
