分为五大类:
1、化学成分类:标准物质,纯的化合物或是有代表性的基体样品,天然的或添加(被)分析物的(如,用作农药残留分析的添加了杀虫剂的动物脂肪),以一种或多种化学或物理化学特性值表征。
2、生物和临床特性类:与目录A相似的标准物质,但以一种或多种生化或临床特性值表征,如酶活性。
3、物理特性类:以一种或多种物理特性值表征的标准物质,如熔点、粘性和密度。
4、工程特性类:以一种或多种工程特性值表征的标准物质,如硬度、拉伸强度和表面特性。
5、产品仅用于科研其他特性。这些类别又被细分为三级子类,例如,在化学成分类中,以微量锰、硅、铜、镍和铬含量表征的铝合金,列于化学成分一金属一有色金属一铝合金的子类中;在化学成分类别中,标准物质还可进一步被分为单一成分的标准物质和基体标准物质两大类;单一成分的标准物质是纯物质(元素或化合物),或纯度、浓度、熔点、熔化焓值、粘度、紫外可见光吸光率、闪点等参考值已精确确定的纯物质的溶液;这类标准物质的重要用途之一是分析仪器的检定或校准。

标准品管理:
(一)规范记录:
建立标准物质台帐,定期更新台账,明确责任主体;
(二)定期核查:
对于标准物质的种类、级别、介质、浓度含量、有效期、批号、环境条件、储存方法、帐物相符、存放环境条件和有效性等等各参数,要定期核查。
(三)期间核查:
有效期短、使用频率高的标准物质,要经常性的核查;
不常使用的标准物质,在分析检测之前核查即可;
稳定性好,还未开封的标准物质,可延长核查周期;
对已开封的标准物质,根据产品性状以及实验室的条件,灵活进行核查。
标准品或对照品的管理规范:
1.规范购入使用台账,严格表明购入时间、生产批号、来源、数量、使用期限等内容;申购的标准品或对照品的批号要与新颁布标准品或对照品批号相符;
2.严格按照规定条件进行储存,标准品或对照品的性状极不稳定,对储存条件和方式非常苛刻;
3.规范管理和使用:
(1)严格按照说明书要求,由于标准品或对照品的不稳定性,若不安产品说明书的要求操作,极易造成较大的误差,从而影响检测结果;
(2)称量精密准确,标准品和对照品的含量测定要求不同,对精密性的要求很高;
(3)对于长期贮存的制备品,应充分考虑各方面的影响因素,规范操作;
(4)同时配制两份对照溶液以控制检验误差,由于现在药品的标准含量测定方法较多采用对照比较法,在测定过程中,仅配制一份对照溶液容易造成因配制对照溶液过程出现偏差;
(5)自行标定的标准品或对照品,严格规范操作,保证标准的可靠传递,并保证其可溯源性和准确性。
