【求助】求助甲醛测试

紫外可见分光光度计(UV)

  • 谁有ISO14184——甲醛测试的中文版,另外可不可以告知ISO14184和GB/T19941-2005的区别,对于甲醛测试,其检测限除了根据MDL以外,还有依据什么,不同的方法各位一般取多少,可否给个建议,谢谢!

    ISO 14184-1:1998 Formaldehyde Standards

    What is Formaldehyde?
    Formaldehyde is a naturally occurring substance in our atmosphere. It is emitted by animals and humans as a by-product of digestion, and it is created during combustion. It can be found in smoke from fires, smog, tobacco smoke and vehicular exhaust fumes. In more concentrated forms, formaldehyde is used in a number of industrial processes in a variety of industries, including the textile industry.

    Why are there Standards for testing formaldehyde levels in textiles?

    Exposure to unsafe levels of formaldehyde can irritate the eyes and skin. If inhaled, formaldehyde may cause headaches, and trigger or aggravate asthma symptoms.

    The ISO Standards for testing formaldehyde provide internationally agreed methods of testing. Levels of formaldehyde in products can vary greatly, as can the ‘total’ amount versus the ‘free’ amount of formaldehyde.

    Product safety is enormously important. Standards help ensure the safety, and reliability of many products and services.

    What Standards are there for testing formaldehyde levels in textiles?
    There are two internationally recognised (ISO) Standards that set out agreed methods for testing formaldehyde levels in textiles:

    ISO 14184-1:1998 Textiles -- Determination of formaldehyde -- Part 1: Free and hydrolized formaldehyde (water extraction method)
    ISO 14184-2:1998 Textiles -- Determination of formaldehyde -- Part 2: Released formaldehyde (vapour absorption method).
    For more information on these Standards, call Standards New Zealand 0800 782 632.

    Additional information on formaldehyde product safety is available from

    我有ISO14184的标准但没有电子版,其实跟GB2912-1没有区别,它是测试针织内样品甲醛含量的标准,GB19941主要测试皮革甲醛的含量。ISO14184-1称取1g样品,加100ml水。GB19941称取2g样品,加入50ml预热到40°c的十二烷基磺酸钠

    这个说的很详细了,可以直接参考GBT 2912-1就可以了

    萃取试剂不一样:ISO14184 针对纺织布料,萃取液用三级水;GBT19941标准变更不是2005版了,针对真皮(不是真皮,按纺织品做),萃取液0.1%十二烷基磺酸钠
