3、cts, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Pub- lications shall not in any respect preclude any member or non-member of EIA from manufacturing or selling products not conforming to such St

4、andards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use by those other than EIA members, whether the standard is to be used either domestically or internationally, Recommended Standards and Publications are adopted by EIA without regard to wh

5、ether or not their adoption may involve patents on articles, materials, or processes. By such action, EIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Recom- mended Standard or Publication. This document was approved by the P-7

6、 Committee on Conductive Products and Techniques. EIA INTERIM STANDARDS EIA Interim Standards contain information deemed to be of technical value to the industry, and are published at the request of the originating Committee without necessarily following the rigorous public review and resolution of

7、comments which is a procedural part of the development of an EIA Recom- mended Standard. EIA Interim Standards should be reviewed on an annual basis by the formulating Committee and a decision made on whether to proceed to develop an EIA Recommended Standard on this subject. EIA Interim Standards mu

Units of Product - The entity

34、 inspected in order to determine its classification as defective or nondefective or to count the number of defects. It may be a single article, a pair, a set, a length, an area, an operation, a volume, a component of an end product, or the end product itself. The product may or may not be the same a

35、s the unit of purchase, supply, or shipment. Lot - The term lot shall mean “inspection lot,“ i.e., a collection of units of product from which a sample is to be drawn and inspected to determine conformance with the acceptable criteria, and may differ from a collection of units designated as a lot fo

36、r other purposes (e.g., production, shipment, etc.). Acceptance Sampling - The process of evaluating a portion of the product in a lot for the purpose of accepting or rejecting the entire lot as conforming or not conforming to a quality specification. When applied consistently to a series of lots, a

37、cceptance sampling will control the risk of accepting lots of a given quality. AOQL - Average Outgoing Quality Limit. The worst percent defective outgoing material expected when using a given sampling plan. AQL - Acceptable Quality Level. The worst percent defective material that is still considered

38、 satisfactory as a process average for the purposes of acceptance sampling. Defect - A condition in which a product, material, or service does not conform to requirements. Failure - A condition in which a product, material, or service does not perform its intended function. Quality - The extent to w

39、hich a product, material, or service conforms to requrements. Fitness for use. Reliability - The probability that a product, material, or service will conform to requirements during a given period of time EIA IS-43 87 3234b00 0002377 2 W EIA/IS-43 Page 5 2.3.1 ABBREVIATIONS CU DGM FCC FP VGM NEC NP
