化学测试混测的风险 The Risk of Compositing Test for Chemical Test

现在越来越多的供应商为了节省成本，会要求实验室在化学测试的时候安排多个部件混测，殊不知这样做会大大提高产品出口的风险，增加测试的成本。首先多个部件混测，每个部件的合格要求就会相应的变小，而且准确性也会差很多，测试不通过的概率就会大大增加，从而造成产品多次重测，其次现在越来越多的国外买家已经明确指出不接受化学测试混测，要求所有部件都要单独进行化学测试。

More and more suppliers require lab to arrange compositing test for chemical test in order to save the cost.But it will raise the risk for product exporting and the cost for product testing.
Firstly,the requirement of compositing test will be decreased，the accuracy will be influenced,the percentage of failure will be increased.
Secondly,more and more overseas' buyer clearly state that they don't accept the result of compositing test for chemical test,all components should be conduct chemical test separately.
