摘要
参考EN71-3:2013+A2:2017对玩具产品中的第一类材质进行测试的时候,发现该标准原文中未对该类材质的取样规格进行明文规定,由于各测试方对该标准的理解不同,导致测试的结果也千差万别,另外测试样品溶液的PH值也是影响最终测试结果的另外一个因素。
Referring to the test results of the first kind of material in toy products in EN71-3:2013+A2:2017,it was found that the original text of the standard did not clearly stipulate the sampling specifications for this kind of material.Due to the different understanding of the standard by different testers,the test results also vary greatly.In addition,the PH value of the test sample solution is another factor that affects the final test results.
