Conductor Secureness Test是UL817标准中的一个试验项目,意思是导线毗连可靠性测试。美规软线组件和电源软线UL817认证需要举行导线毗连可靠性测试,接下来为各人先容UL817导线毗连可靠性测试。

依据标准:
UL817 (81.1, 81.2)
测试工具:
插头的端子( blade,pin)或软线毗连器的接触片( female contact)与电线毗连好后,模塑或装配到插头或毗连器之前。
样品数目:
Normal: 13 条
Tightened: 20 条
Reduced: 5 条
测试要领:
在电线与端子之间施加一个力(电线大于或即是18AWG时为20磅( 89牛),电线小于18AWG时为8磅( 36牛)),坚持1分钟。
判断:
毗连处无断裂为及格。

Conductor Secureness Test
81 .1 If a conductor of a flexible cord is connected to an element (male blade or pin or female contact) of a fitting before the element has been assembled to the fitting, the connection shall not break under a pull applied for 1 minute between the element and the conductor before the element has been assembled into the fittings. A pull of 20 lbf (89 N) shall be applied if the conductor is No. 1 8 AWG or larger in size. If a smaller cord is used, the pull shall be 8 lbf (36 N).
81 .1 若是在元件装配到配件上之前,软线的导体已毗连到配件的元件(公片或销或母点)上,在元件装配到配件中之前,在元件与导体之间施加1分钟的拉力,该毗连不得断开。若是导体是No. 1 8 AWG或更大的尺寸,则应施加20 lbf (89 N)的拉力。若是使用较小的绳,拉力应为8 lbf (36 N)。
81 .2 While the test in 81 .1 is being performed, the angle between the element and the cord conductor is to be the same as in the completely assembled fitting. The test shall be performed by using dead weights or, at the manufacturer’s option, a power driven tensile testing machine. If a tensile testing machine is used it shall have jaws suitable for holding the specimen and capable of applying the minimum required tensile load to the specimen while separating at a uniform rate not exceeding 1 inch/minute (25.4 mm/min). The machine shall be equipped with a scale from which the load can be read to a value of 0.1 lbf (0.4 N). The accuracy of the scale shall be within ±2 % of the value read, and weights shall be provided for calibrating the machine.
81 .2 在举行81 .1中的测试时,元件与芯线导体之间的角度应与完全组装的毗连件中相同。测试应使用自重,或凭证制造商的选择,使用动力驱动拉力试验机。若是使用拉力试验机,它应该有适合容纳试件的爪,并能够在以不凌驾1英寸/分钟(25.4毫米/分钟)的匀称速率疏散试件时,对试件施加最小所需的拉力载荷;涤Ω门浔敢桓隹潭,从它可以读出负载的值为0.1 lbf (0.4 N)?潭鹊木扔υ诙寥≈档摹2%以内,并应提供用于校准机械的重量。
