GB/T 12490-2014 in English

《GB/T 12490-2014纺织品 色牢度试验 耐家庭和商业洗涤色牢度》由TC209（全国纺织品标准化技术委员会）归口，TC209SC1（全国纺织品标准化技术委员会基础标准分会）执行，主管部门为中国纺织工业联合会。
本标准规定了测定各种类型的常规家庭用纺织品耐家庭和商业洗涤色牢度的方法。工业及医院用纺织品可能需要(在某些方面)洗涤条件更为剧烈的特定洗涤程序。
由于试验过程中解吸附作用和(或)摩擦作用,经一次单个(S)试验,试样所造成的褪色和沾色非常接近于一次家庭和商业洗涤,而经一次复合(M)试验,则接近五次以上温度不超过70 ℃的家庭和商业洗涤的效果。M 试验比S试验的机械作用更为强烈。
本标准的方法并不反映在商业洗涤程序中的荧光增白剂的效应。
本标准的试验方法根据给定的洗涤剂和氯漂方法制定,使用其他的洗涤剂和氯漂方法可能需要不同的试验条件。

This standard specifies methods intended for determining the resistance of the colour of textiles of all kinds and in all forms to domestic or commercial laundering procedures used for normal household articles using a reference detergent. Industrial and hospital articles may be subjected to special laundering procedures which may be more severe in some aspects.
The colour loss and staining resulting from desorption and/or abrasive action in one single (S) test closely approximates to one commercial or domestic laundering. The results of one multiple (M) test may in some cases be approximated by the results of up to five domestic or commercial launderings at temperatures not exceeding 70℃. The M tests are more severe than the S tests because of an increase in mechanical action.
The methods specified in this standard do not reflect the effect of optical brighteners present in commercial washing products.
The methods specified in this standard are designed for the detergents and bleach systems given. Other detergents and bleach systems may require different conditions and levels of ingredients.
