2、2 ELECTRONIC INDUSTRIES ASSOCIATION ENGINEERING DEPARTMENT EIA Engineering Standards and Publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the p

3、urchaser in selecting and obtaining with minimum 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, n

4、or shall the existence of such Standards and Publications preclude their voluntary use by those other than IA members, whether the standard is to be used either domestically or internationally. I Recommended Standards and Publications are adopted by EIA in accordance with the American National Stand

5、ards Institute (ANSI) patent policy. 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 Standard is considered to have International Standardization implication, but t

6、he international Electrotechnical Commission activity has not progressed to the point where a valid comparison between the EIA Standard and the IEC document can be made. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements. i

7、t is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use.
