3、29.5 and 33.1Subject: Weight requirement for Flexing Test and Crimp Connection SecurenessTest for conductors smaller than 18 AWGDECISION:29.5 Each connector is to be secured in the jaws of the flexing machine so that the point of flexible lightbody exit is at the center of rotation. The rotating jaw
4、s are to be adjusted to rotate to an angle of 90degrees to each side of the centered position. At the centered position, the flexible light body is to hangvertically and a test weight of 10 ounces (284 g) for 18 AWG and larger conductors or 4 ounces (113 g)for conductors smaller than 18 AWG shall be
5、 attached to the flexible light body approximately 12 inches(305 mm) from the point of rotation.33.1 Six samples of the individual crimp connections used to make electrical connection to the flexiblelight conductors or connectors are to be subjected to this test. Samples are to be tested before thec
6、rimped connections have been assembled or molded into its final application. Each terminal is to be heldrigidly and a force of 20 pounds (89 N9.1 kg) weight for 18 AWG and larger conductors or 8 pounds (36N) for conductors smaller than 18 AWG shall be applied attached to the conductor in a direction
7、 normalto the longitudinal axis of the terminal and conductor. The forceweight is then to be gradually applied tothe conductor released to hang freely suspended and maintained for a duration of one minute.RATIONALE FOR DECISION:Table 14.1 was recently updated to include 22 AWG and 20 AWG conductors.
8、 The requirements for theweights in Section 29, Flexing Test, and Section 33, Crimp Connection Secureness Test, however, remainunchanged from the 18 and 16 AWG conductor sizes and needed to be updated to reflect the appropriateforces that should be applied when 22 AWG or 20 AWG conductors are employ
