本来一直以为ASTM是有一边尺寸小于100mm,就不需要做厚度测试了，今天一看，发现不是如此，这句话的意思应该是当塑料薄膜和袋子的短边的尺寸为3.94in.(100mm).袋子的尺寸应该以袋子的形状来测量，而不是剪开成为单层薄膜来测量．+ a* [6 {4 h J3 ^8 g

dimension 是指袋子的尺寸大小还是厚度大小呢？？欢迎大家讨论，谢谢作者: shartboy 时间: 2009-12-4 23:06
这点讲的是胶袋或者塑胶薄膜只要最小一边的尺寸小于100mm就是豁免的，不需要进行厚度测量。胶袋的长宽尺寸是以袋子的形状来测量，而不是剪开来测量。作者: peterxu 时间: 2009-12-4 23:43
可是他没有一个单词和豁免有关呀？？？作者: shartboy 时间: 2009-12-5 09:56
