3、haser 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 TIA/EIA from manufacturing or selling products not conforming to such Standards and Publications,

4、nor shall the existence of such Standards and Publications preclude their voluntary use by those other than TIA/EIA members, whether the standard is to be used either domestically or internationally. Standards and Publications are adopted by TIA/EIA in accordance with the American National Standards

5、 Institute (ANSI) patent policy. By such action, TIA/EIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication. TIA/EIA INTERIM STANDARDS TIA/EIA Interim Standards contain information deemed to be of technical va

6、lue to the industry, and are published at the request of the originating Committee without necessarily following the rigorous public review and resolution of comments which is a procedural part of the development of a TIA/EIA Standard. TIA/EIA Interim Standards should be reviewed on an annual basis

7、by the formulating Committee and a decision made on whether to proceed to develop a TIA/EIA Standard on this subject. TIA/EIA Interim Standards must be cancelled by the Committee and removed from the TIA/EIA Standards Catalog before the end of their third year of existence. Publication of this TIA/E

8、IA Interim Standard for trial use and comment has been approved by the Telecommunications Industry Association. Distribution of this TIA/EIA Interim Standard for comment shall not continue beyond 36 months from the date of publication. It is expected that following this 36 month period, this TIA/EIA

9、 Interim Standard, revised as necessary, will be submitted to the American National Standards Institute for approval as an American National Standard.
