3.3 expendable parts: Parts normally used up or con- sumed in service, such as seals, gaskets, filters, packing, cov- ers, guards, breathers, drains, break/clutch linings, drive chains, dies, and miscellaneous hardware and fasteners. 3.4 inspection: Comparison of equipment conformity to predetermined standards, followed by a determination of action required. 3.5 load test: Aprocedure wherein a load is applied to verify the serviceability of equipment. 3.6 maintenance: Action, including inspection, ad- justments, cleaning, lubrication, testing, and expendable parts replacement, necessary to maintain the serviceability of the equipment. 3.7 manufacturer: A term denoting individuals or companies, who make or process equipment or material for which API Standards have been or are being formulated. 3.8 owner: An individual, legal entity, or organization holding legal title to the equipment. 3.9 primary load: The primary load to which the equipment is subjected during normal operations, which re- sults in stress to the critical areas. 3.10 primary load carrying components: Those components of the covered equipment through which the primary load is carried. 3.11 remanufacture: Actions performed on equip- ment that involve a special process or machining. 3.12 repair: Actions performed on equipment that in- volve replacement of parts (other than expendables), but ex- clude remanufacturing operations. 3.13 serviceability: The condition of a piece of equip- ment at any point in time that affects the ability of the equip- ment to perform its function(s) as intended. 3.14 special process: An operation that may change or affect the mechanical properties, including toughness of the materials used in equipment. 3.15 testing: Actions that are carried out on a piece of equipment to ensure that it can perform a required function. 3.16 users: Aterm denoting individuals or companies, who use equipment or material, or implement recommended practices.
6 Repair
6.1 PROCEDURES Manufacturers should provide adequate inspection crite- ria to allow the equipment owner or user to identify the na- ture of repairs that may be required. If repairs are not performed by the manufacturer, they should be performed us- ing methods or procedures established in accordance with 1.2. 6.2 SURFACE INDICATIONS Surface indications identified by NDE may be allowable or nonallowable, depending on the size, shape, and location as defined by the manufacturer. 6.2.1 Allowable Surface Indications Allowable surface indications are surface indications of size, shape, and location that need not be removed. 6.2.2 Nonallowable Surface Indications Nonallowable surface indications may be classified as follows: a. minor surface indications: Minor surface indica- tions may be removed by a limited degree of filing or grind- ing within limits specified by the manufacturer. Caution should be exercised to prevent heating to an extent that could change the mechanical properties, including toughness, of the material. b. major surface indications: Major surface indica- tions, which require material removal beyond the limits specified by 6.2.2.a, should be corrected by remanufacture.
