[中文适用范围]： 本标准规定了适用于表面活性剂或洗涤剂的单一或混合粉状、浆状或液状产品的样品分样方法。 由于下列原因需对样品进行分样: a) 由500 g以上的大批混合样品中制备250g以上的最终样品或实验室样品； b) 由最终样品制备若干份相等的实验室样品， 参考样品和保存样品， 每份样品质量都在250g 以上； c) 由实验室样品制备试验样品。 [外文原描述]： A bulk sample is reduced by a mechanical process until a reduced sample is obtained. The reduced sample may be used for the following purposes: a) the preparation of a final sample or a laboratory sample of mass greater than 250 g from a blended bulk sample of mass greater than 500 g; b) the preparation of several equivalent laboratory samples and/or reference samples and/or storage samples, each of a mass greater than 250 g, from a final sample; c) the preparation of a test sample from a loboratory sample.
