实验室间纺织品甲醛测试稳定性探讨

Study of stability of inter-laboratory formaldehyde test in textiles

纺织品甲醛含量作为强制性检测项目,要求第三方实验室具有稳定的技术能力,以保证检测结果的准确有效。分析了连续4年参加同一项目比对的实验室测试结果,以此来判断这些实验室甲醛测试能力是否满足要求。结果表明,大部分实验室采用国标或欧标,无论是利用水萃取法还是蒸汽吸收法进行检测,实验室技术能力均较稳定。

As a compulsory testing project,test for formaldehyde content of textiles requires that the third-party laboratory has stable and sustainable testing capability to guarantee the accuracy and effectiveness of testing results.In order to verify the formaldehyde testing capacity of the laboratories,inter-laboratory testing results from the same project in four consecutive years are compared and analyzed.The results show that most of the laboratories adopted national or European standards,and their technical capabilities are stable for both water extraction and vapor absorption methods.
