37、 EIA STANDARD AND SPECIFICATION NUMBERING i STANDARD A document that establishes engineering and technical requirements for processes, procedures, practices and methods that have been decreed by authority or adopted by consensus. Standards may also be established for selection, application and desig
38、n criteria for material. Standards and other documents not in the specification format use only the EIA basic numbering system as follows: EIA-123 Original Standard EIA-123-1 Addendum to Original Standard EIA-123-A First Revision of original Standard incorporating all Addenda SPECIFICATION A documen
39、t prepared specifically to facilitate procurement which clearly and accurately describes the essential technical requirements for purchased material. Procedures necessary to determine that the requirements for the purchased material covered by the specification have been met shall also be referenced
40、 or included. EIA Specifications use the following system: Standard or Generic Specification Standard Prefix for all Numbers Sectional Specification Designator Blank Detail Specification Designator -zJ A - A - Detail Specification Designator EIA 1230000 EIA 123A000 EIA 123AAOO EIA 123AAAA EIA 123OOA
41、A is a Generic Specification is a Sectional Specification is a Blank Detail Specification is a Detail Specification is a Detail Specification for which no Sectional or Blank Detail Specification was issued. NOTES: 1. Some older specifications may not have been converted to this numbering system. 2. See EP-11 “Guide for the Preparation of Specification Using IECQ-System Format,“ for more detail.
