3、delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of EIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such Standards and Publ

4、ications 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 whether or not their adoption may involve patents on articles, materials, or p

5、rocesses. By such action, EIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Recommended Standard or Publication. This EIA Specification is considered to have International Standardization implication, but the International Elect

6、rotechnical Commission activity has not progressed to the point where a valid comparison between the EIA Specification and the IEC document can be made. This Specification does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the res

7、ponsibility of the user of this Specification to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.

18、 objective of the test is to assess whether a switch, while operating, will ignite an ambient explosive atmosphere prevalent in aircraft applications. This test is not necessary for switches which are enclosed in housings (casings) designed to prevent flame or explosion propagation. Test Method: Swi

19、tches shall be tested in accordance with Method 109 of MIL-STD-202. Switches shall be operated at their maximum rated dc inductive current at the rated voltage. Criteria: The explosive mixture in the test chamber surrounding and external to the switch shall not explode whether or not an explosion oc

20、curs within the switch. Switches shall be electrically operable after the test.

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.
