By such action, ECIA does not assume any liability to any patent owner, nor does it assume any obligation wha
5、tever to parties adopting the Specification or Publication. This EIA specification is considered to have International Standardization implications, but the International Electrotechnical Commission activity has not progressed to the point where a valid comparison between the EIA standard and the IE

It is the responsibility of the user of this Specification to establish appropriate safety and health practices and to determine the applicabi
7、lity of regulatory limitations before its use. NOTE The users attention is called to the possibility that compliance with this standard may require use of an invention covered by patent rights. By publication of this standard, no position is taken with respect to the validity of any such claim(s) or
8、 of any patent rights in connection therewith. If a patent holder has filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license, then details may be obtained from the standards devel

Unless otherwise specified, mated sets of connectors shall be tested. When the initial tests have been completed, all spe
18、cimens are divided up according to the test groups. Care shall be taken to keep a particular combination of connectors together during the complete test sequence, i.e., when unmating is necessary for a certain test, the same connectors as before shall be mated for the subsequent tests. Before testin
19、g commences, the connectors shall have been stored for at least 24 hours in the non-inserted state under normal climatic conditions for testing. In the following test sequence tables, where an EIA test is specified without a letter suffix, the latest approved version of that test shall be used. EIA-
