35、EIA STANDARD AND SPECIFICATION NUMBERING STAN DARD 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 design
36、criteria for material. i 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
37、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 referenc
38、ed or included. EIA Specifications use the following system: E/A 1 i 3 Standard Prefix for ail Numbers Standard or Generic Specification Sectional Specification Designator Blank Detail Specification Designator I Detail Specification Designator A I EIA I230000 EIA 123A000 EIA 123AAOO EIA 123W EIA 123
39、OOAA 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.
