If the plastics&housing described in the FUS procedure is UL R/C QMMY2, then you need to control the ratio of the recyle material, but if the one is the UL R/C QMFZ2, then basically, UL does not care how much the recycle material was used, and that's the responsiblity of the manufacturer to make sure the fabricated parts can comply the standard's requirements.作者: Andy.Yang 时间: 2014-6-19 12:53 本帖最后由 Andy.Yang 于 2014-6-19 12:55 编辑 4 D' F( j2 e. w# o$ l9 q2 F
