EN只拉一次
ASTM; 如果合适可以再做扭拉测试作者: yin168 时间: 2011-10-29 21:21
hewei,你好,请问ASTM哪个条款有提到合适的情况下可以再进行扭拉呢?合适的情况又是指哪些呢?谢谢...作者: 小李子子 时间: 2011-10-29 21:21
请看8.81作者: yin168 时间: 2011-10-29 21:22
ASTM F963 08 Clause 8.8 最后的一段话
Projections, parts, or assemblies
that are mounted rigidly on an accessible rod or shaft designed
to rotate along with the projections, parts, or assemblies shall
be tested with the rod or shaft clamped to prevent rotation. If
a component that is attached by a screw thread that has been
assembled by the manufacturer, or that has been assembled to
the manufacturer’s instructions, becomes loosened during application
of the required torque, continue to apply the torque
until either (1) the required torque is exceeded, or (2) the part
disassembles. The test should be terminated if it becomes
obvious that the part under test will continue to rotate at less
than the required torque limit and will not disassemble.
8.8.1 8.8.1 If the part disassembles, evaluate it for compliance
with the appropriate requirements. If the disassembly exposes
an accessible component that can be grasped as noted above,
repeat the torque test on that component.
8.8.1中的the disassembly part是不是指Projections, parts, or assemblies
that are mounted rigidly on an accessible rod or shaft designed
to rotate along with the projections, parts, or assemblies shall
be tested with the rod or shaft clamped to prevent rotation.呢??
如果是的话,那这个纸牌是不是不需要拉呢??谢谢作者: 小李子子 时间: 2011-10-29 21:22
是指rojections, parts, or assemblies
that are mounted rigidly on an accessible rod or shaft designed
请看8.9
所有拉力应该在扭力的基础上完成,
你试想一下:既然能够做扭力,那么该部件是不是能被食指和拇指夹住,或被牙齿咬住,及
那么拉力的前提条件就是:能被食指和拇指夹住,或被牙齿咬住,以及可预见的可触作者: yin168 时间: 2011-10-29 21:22
呵呵,其实这个问题和那个小部件的问题是同根同源的,也是做EN71,如果3+以上不用做滥用测试,那就不会有小部件了,也就不需要加警告语了..................正常使用是不会产生小部件的呀....作者: 小李子子 时间: 2011-10-29 21:23
PETER 兄:产品是做EN啊!
我还以为做ASTM作者: Denny.Xie 时间: 2011-10-30 09:21
EN 与ASTM是不一样的，要分开来学作者: worldlink 时间: 2011-10-30 12:43
有没有答案呢，我也想学学。作者: waynesong320 时间: 2011-11-1 14:55
缺口處已拉爛了，已經有小件了。。。。。。。作者: aiyuzhibo 时间: 2012-6-20 23:04

亏你还是高级验货员?我那10多经验不是低档次的了?
