ISO 6887-4:2003规定了食品微生物检验用样品和十进制稀释液的制备规则，但ISO 6887其他部分所述的除外。ISO 6887-1定义了微生物检验用初始悬浮液和十进制稀释液的制备一般规则。ISO 6887-4:2003仅描述了同时适用于几种微生物的制备方法。它不包括仅适用于单个微生物检测和/或计数的制剂，其中有关该微生物的相关国际标准中描述了该制剂的制备方法。ISO 6887-4:2003适用于以下产品:酸性产品的一般情况；脂肪含量高的食物，不包括人造黄油和黄油；面粉、全谷物、谷物副产品、动物饲料和牛蛋糕；非常硬的产品；明胶；人造黄油和黄油；脱水产品和冻干产品（乳制品和蛋制品除外）；鸡蛋和蛋制品；发酵产品（含有活微生物的产品）；糕点和蛋糕。

ISO 6887-4:2003 specifies rules for the preparation of samples and decimal dilutions for the microbiological examination of food products other than those covered in other parts of ISO 6887. ISO 6887-1 defines the general rules for the preparation of the initial suspension and decimal dilutions for microbiological examination.ISO 6887-4:2003 only describes methods of preparation that are applicable to several microorganisms simultaneously. It excludes the preparations that only apply to the detection and/or enumeration of a single microorganism where the methods of preparation are described in the relevant International Standard concerning that microorganism.ISO 6887-4:2003 is applicable to the following products: general case for acidic products; foods with a high fat content, excluding margarine and spreads; flours, whole cereal grains, cereal by-products, animal feeds and cattle cake; very hard products; gelatine; margarine and spreads; dehydrated products and freeze-dried products (except dairy products and egg products); egg and egg products; fermented products (products containing live microorganisms); pastries and cakes.
