标题: UL 987 bench grinder 问题 [打印本页] 作者: simondai 时间: 2008-3-29 22:27 标题: UL 987 bench grinder 问题 手头碰到一个case,是一个8" bench grinder,它２头用的都是布轮，不是砂轮，所以也没有提供WHEEL GUARD和EYE GUARD. / \* B, r. S$ a9 \+ K; p* e5 y/ w/ t
但标准里有如下要求： % `5 j6 v* Z8 G x s . q5 u9 l% y6 a; s* |2 y& n4 z35.4 A grinder shall be provided with a wheel guard to reduce the risk of injury to persons in the event of wheel breakage. # J) R* |; m0 @6 D3 ?. ~/ _. P( e. _2 y" B: i
35.14 A grinder shall be provided with an eye shield employing clear, nonshattering material and mounted so that loosening of the grinding wheel guard is not necessary for adjustment of the shield. The eye shield of a grinder intended for use with grinding wheels more than 5 inches (127 mm) in diameter shall be such that the eye shield can be moved out of place for grinding large objects. 8 U0 M- o( U9 c.

我个人觉的这２个要求不适用与这种布轮类型的bench grinder,但我找不到免除条款．有高手能用标准原话指点下吗？作者: zhh0815 时间: 2008-3-31 15:47
这种标准里面没有考虑周全的产品建议直接和UL工程师协商解决方案, 毕竟最终是要他们认可的.
