25、.2 Definitions 2.2.1 CONCENTRIC LAY Concentric lay is defined as a central strand surrounded by one or more layers of helically wound strands. 2.2.2 LOT All the stranded conductors of one part number made under the same essential conditions, produced on a substantially continuous basis, and offered
26、for inspection at one time are considered a lot for purposes of sampling. 2.2.3 SAMPLE The sample is the group of sample units selected from the lot for the purpose of inspection. 2.2.4 SAMPLE UNIT The sample unit consists of a single piece of finished conductor of sufficient length to permit all ap
27、plicable examinations and tests. Not more than one sample unit for each group of tests should be taken from a single unit of product. 2.2.5 UNIT OF PRODUCT A unit is one continuous length of conductor. 2.2.6 QUALIFICATION INSPECTION Qualification inspection is a process that demonstrates that a comp
28、onent is capable of fully conforming to all the requirements defined in a standard. Qualification inspection includes definition of the measurements, tests, analysis, and associated data which provides consistent rationale for acceptance of a particular suppliers design as meeting the standard requi
29、rements typically prior to acquisition by the Purchaser. 2.2.7 QUALIFIED PRODUCTS LIST A Qualified Products List is a list of suppliers whose products have been evaluated to a defined standard using a defined process and who are authorized to provide those products to a purchaser upon request. When
30、a Qualified Products List is specified only approved suppliers are authorized to provide products under the part number defined in the component standard. A Qualified Products List is established and maintained by a Qualifying Activity. 2.2.8 QUALIFYING ACTIVITY A Qualifying Activity is a function e
31、stablished by an SAE specification that has a defined process used to consistently evaluate all suppliers products in accordance with the component standard. SAE INTERNATIONAL AS29606 Page 5 of 35 2.2.9 QUALITY CONFORMANCE INSPECTION Quality Conformance Inspection is a process which includes measure
32、ments, non-destructive test, analysis, and associated data that will provide verification that a particular individual component continually conforms to the requirements defined in the standard. 2.2.10 QUALIFICATION BY SIMILARITY An alternate Qualification Inspection process accomplished without com
33、pleting all of the measurements, test, and analysis requirements defined in the standard. Acceptance and the extent of similarity, is determined by the Qualifying activity. Similarity is established through a rationale that certain designs, materials, and/or processes are identical to those already
34、approved through qualification of the components. Verification testing for the new product is not required or reduced for designs, materials, and/or processes already approved. 2.2.11 PURCHASER A purchaser is an activity that can issue a purchase order or contract.2.2.12 SUPPLIER A supplier is an or
35、iginal component manufacturer or a value added component manufacturer (i.e. distributer, assembly plant, etc.) which has design and production control of the processes used to produce the final component in accordance with the standard. 2.2.13 QPL SOURCE In order to be considered for listing on a Qu
36、alified Products List (QPL), a supplier has to comply with the conditions listed below.1. The potential source has to have control of the engineering drawings for manufacturing the products. 2. The potential source has to do final inspection and shipping from the location to be listed on the QPL. 3.
37、 The potential source had to be responsible for all the initial and periodic qualification requirements identified in the specification.3. REQUIREMENTS 3.1 Qualification (see 4.4) The coated copper and copper-alloy conductors furnished under this specification shall be products, which are authorized
38、 by the qualifying activity for listing on the applicable qualified products list at the time set for opening of contract bids (see4.1 and 7.5.6) or purchase orders. Qualification requirements are in accordance with 4.4 herein. 3.1.1 Conformity to Qualified Sample It is understood that conductors su
39、pplied under contract shall be the same material formulations, material sources, and manufacturing processes as approved by the qualifying activity. Any unapproved changes made after the qualification approval date, unless accepted by the qualifying activity, may constitute cause for rejection. 3.2
