检测方法标准是皮革各项性能指标检测的依据,检测方法标准是否先进,直接影响到皮革性能检测结果的公正和被认可性。中国是皮革大国,标准化工作对促进中国皮革质量的提高,规范中国皮革行业的发展具有很重要的作用,国家和行业对标准的制定也越来越重视,行业的标准意识也越来越高。在皮革标准化工作人员和整个皮革行业的共同努力下,中国皮革检测方法标准已经有了长足的进步,特别是最近几年,标准化工作人员做了很多工作,加快了中国检测方法标准同国际标准的接轨速度,使检测方法标准的采标率有了很大提高。
从表中可以看出,中国皮革检测方法标准与国家标准还有一定差距,特别是随着皮革行业的发展,人们对皮革性能的要求不断发生变化,我们对检测方法标准的制定也要不断适应世界皮革行业发展的需求,加快对旧方法标准的修订和新方法标准的制定。
