Existence of such Standards and Publications shall not in any respect preclude any member or nonmember of ECIA from manufacturing or selling products not conforming to such Standards and Publications, nor shall the existence of such Standards and Publications preclude their voluntary use
4、 by those other than ECIA members, whether the standard is to be used either domestically or internationally. Standards and Publications are adopted by ECIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, ECIA does not assume any liability to any pa

This EIA standard is considered to have International Standardization implications, but the International Electrotechnical Commission activity has not progressed to the point where a valid compari
6、son 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. It is the responsibility of the user of this Standard to establish appropriate safety and health practices a
7、nd to determine the applicability of regulatory limitations before its use.

9、mum outside diameter of the cable jacket for diameters less than 20 millimeters (0.8 inch), unless otherwise specified in the referencing document. For 24 AWG conductors or smaller the roller diameters shall be specified in the referencing document. 2.1.1.3 Equipment for checking the electrical cont
10、inuity of the conductor-to-contact joints, prior to, during, and subsequent to testing. 2.1.1.4 Equipment, such as magnifiers (approximately 3X) for examining cable-to-plug seal or cable jacket prior to and subsequent to testing. 2.1.2 Test condition II, flat cable 2.1.2.1 A fixture capable of gripp
11、ing the cable 305 millimeters (12 inches) from the connector with uniform tension of 350 Newtons/meter 20 Newtons/meter (2.0 pounds/inch 0.1 pound/inch) of cable width and capable of moving either the cable or connector through an arc of 140 10; see figure 2, method 2, unless otherwise specified in
12、the referencing document. 2.1.2.2 Equipment capable of monitoring current of 100 milliamperes and to indicate a discontinuity of 1 microsecond or longer interruption of current flow. 3 Test specimen 3.1 Description The test specimen shall consist of a cable terminated to a plug or receptacle connect
13、or with molded boot or mechanical strain relief. 3.2 Preparation 3.2.1 Test condition I, round jacketed cable The test specimen shall be mounted as show in figure 1 with the following conditions: 3.2.1.1 Its cable is loosely but almost tangentially situated between the two rollers that are spaced fa
14、rther apart than the maximum diameter of the cable, see 2.1.1.2. 3.2.1.2 Dimension X (see figure 1) shall be between the junction of the molded boot or mechanical strain relief and the cable jacket and the centerline if the rollers. Dimension X shall be specified in the referencing document. 3.2.1.3
15、 A weight of 454 grams (1 pound) shall be attached to the free end of the cable assembly, unless otherwise specified in the referencing document. EIA-364-41E Page 3 3.2.2 Test condition II, flat cable The test specimen shall be mounted as shown in figure 2. 3.2.2.1 The assembled wired connector shal
16、l be installed in the fixture described in 2.1.2.1. 3.2.2.2 Connector mounting and cable tension fixture shall be clamped so slippage is minimal Care shall be taken that applied clamping pressure is not so great as to damage connector or cable. 4 Test procedure 4.1 Test condition I, round jacketed c
17、able NOTE For cross reference to previous MIL-STD-1344 designations see Annex A. 4.1.1 Check the electrical continuity of the conductor to contact joints. 4.1.2 With the test specimen mounted as in 3.2.1 and figure 1, forces are applied so as to cause the molded boot or strain relief to be repeatedl

Unless otherwise specified, the cycling rate shall be 12 cycles per minute to 14 cycles per minute. 4.1.3 Unless otherwise specified in
19、 the referencing document, at the completion of 100 cycles, examination of seal, jacket and cable holding fixture shall be made to determine the presence or absence of failure modes; see 1.2.1. Electrical continuity shall then be checked to determine presence or absence of failure mode; see 1.2.2 th
