另附录I对六价铬的方法提到:
1。determination of the content of total chromium2.safety assessment of the toy material 就是说对二类我们可以测总铬小于0.005就可以说合格。另可以进行安全评估,评估产品生产工艺,和产品本身的材料一般不含六价铬一般也可以认为是安全合格的
标准都提到:
The method in Annex F is not sufficiently sensitive for category I and II toy materials.
For Chromium VI the method in Annex F the limit of quantification is higher than the migration limit for category I and II toy materials.
能做到三类就可以了

?客户送一类,二类的怎么检测?三类的很容易就可以做出来了

For Chromium VI the method in Annex F the limit of quantification is higher than the migration limit for category I and II toy materials. Compliance with the limits cannot be demonstrated by a migration test, however other options are available:
- determination of the content of total Chromium;
- safety assessment of the toy material.
不能评估,在报告中作出解释。

直接收样就不收好了,就说做不了
这是不可能的。II类0.005mg/kg的限值几乎没有几家实验室有把握做得到的。
上次去上海一家检测外企去参观,他们新买的agilent 的LC-ICP-MS,能够做到10ppt的。
