大家都用什么规格的测厚规
如题，大家都谈谈用怎样规格的测厚规，目前可能只有ISO 8124里面对测厚规要求的比较细致，要求参数如下：
1.上下两个测量面是平面且直径6±1mm，两个平行面误差5微米
2.施加的负荷是0.75±0.25N
3.能够准确到4微米（EN 71 要求 1微米）
如果大家又符合这些参数的测厚规，请告知怎样购买，谢谢
雖然按UL要求買了一個,但一直很少用,:L CHENGFEGO 发表于 2013-12-19 15:46 static/image/common/back.gif

请教一下UL什么要求 千分尺不符合要求吗？
一直在用千分尺

请教一下UL什么要求
a dial micrometer having a 6.3 to 6.4 mm (0.248 to 0.252 in) diameter flat presser foot
exerting a total force of 0.83 ±0.03 N (3.0 ±0.1 ozf) on a rectangular anvil measuring
approximately 9 x 2 mm (0.35 x 0.08 in). The face of the anvil on the minor dimension shall be
slightly convex. Alternatively, these measurements shall be made with a dead-weight dial
micrometer having a presser foot 6.4 ±0.2 mm (0.248 ±0.010 in) in diameter and exerting a total
of 85 ±3 gf or 0.83 ±0.03 N (3.0 ±0.1 ozf) on the specimen – the load being applied by means
of a weight. The presser foot shall be at least 2 mm (0.08 in) onto the edge of the specimen for
each measurement. Micrometers shall have a resolution and accuracy of 0.01 mm (0.001 in);
f) a micrometer with a resolution and accuracy of 0.001 mm (0.0001 in);
就是UL用來測量啞鈴片厚度的,

某些参数更加苛刻，不过不适用iso 8124 yearl 发表于 2013-12-19 15:58 static/image/common/back.gif

国际标准更新后，感觉在力值方面应该达不到要求 lengchuan000 发表于 2013-12-19 16:47 static/image/common/back.gif

刚才问了计量的同事，千分尺的测量力是5N至10N，显然不符合要求。
