自20世纪60年代以来，AATCC和其他测试和开发小组一直使用标准参考洗涤剂。AATCC标准参考洗涤剂124和WOB（不含增白剂）是AATCC采用的第一种配方，代表了那个时代典型的家庭洗涤产品，主要是磷酸盐制成的粉末洗涤剂。由于环境压力，洗涤剂配方变化的激增和磷酸盐的消除，标准参考洗涤剂124和WOB已经过时。自从124和WOB停止使用以来，新的代表性洗涤剂已可供使用。以下段落提供了洗衣粉趋势和AATCC标准参考洗涤剂的一些观点。

The AATCC and other testing and development groups have used standard reference detergents since the 1960s. AATCC Standard Reference Detergent 124 and WOB (without brightener) were the first formulations adopted by the AATCC to represent typical home laundering products of that era, primarily phosphate-built powder detergents. The proliferation of detergent formula variations and the elimination of phosphate due to environmental pressures made Standard Reference Detergents 124 and WOB obsolete.Since the discontinuation of 124 and WOB, new representative detergents have been available for use. The following paragraphs provide some perspective on laundry detergent trends and the AATCC standard reference detergents.
