分為五大類:
1、化學(xué)成分類:標(biāo)準(zhǔn)物質(zhì),純的化合物或是有代表性的基體樣品,天然的或添加(被)分析物的(如,用作農(nóng)藥殘留分析的添加了殺蟲劑的動(dòng)物脂肪),以一種或多種化學(xué)或物理化學(xué)特性值表征。
2、生物和臨床特性類:與目錄A相似的標(biāo)準(zhǔn)物質(zhì),但以一種或多種生化或臨床特性值表征,如酶活性。
3、物理特性類:以一種或多種物理特性值表征的標(biāo)準(zhǔn)物質(zhì),如熔點(diǎn)、粘性和密度。
4、工程特性類:以一種或多種工程特性值表征的標(biāo)準(zhǔn)物質(zhì),如硬度、拉伸強(qiáng)度和表面特性。
5、產(chǎn)品僅用于科研其他特性。這些類別又被細(xì)分為三級(jí)子類,例如,在化學(xué)成分類中,以微量錳、硅、銅、鎳和鉻含量表征的鋁合金,列于化學(xué)成分一金屬一有色金屬一鋁合金的子類中;在化學(xué)成分類別中,標(biāo)準(zhǔn)物質(zhì)還可進(jìn)一步被分為單一成分的標(biāo)準(zhǔn)物質(zhì)和基體標(biāo)準(zhǔn)物質(zhì)兩大類;單一成分的標(biāo)準(zhǔn)物質(zhì)是純物質(zhì)(元素或化合物),或純度、濃度、熔點(diǎn)、熔化焓值、粘度、紫外可見光吸光率、閃點(diǎn)等參考值已精確確定的純物質(zhì)的溶液;這類標(biāo)準(zhǔn)物質(zhì)的重要用途之一是分析儀器的檢定或校準(zhǔn)。

標(biāo)準(zhǔn)品管理:
(一)規(guī)范記錄:
建立標(biāo)準(zhǔn)物質(zhì)臺(tái)帳,定期更新臺(tái)賬,明確責(zé)任主體;
(二)定期核查:
對于標(biāo)準(zhǔn)物質(zhì)的種類、級(jí)別、介質(zhì)、濃度含量、有效期、批號(hào)、環(huán)境條件、儲(chǔ)存方法、帳物相符、存放環(huán)境條件和有效性等等各參數(shù),要定期核查。
(三)期間核查:
有效期短、使用頻率高的標(biāo)準(zhǔn)物質(zhì),要經(jīng)常性的核查;
不常使用的標(biāo)準(zhǔn)物質(zhì),在分析檢測之前核查即可;
穩(wěn)定性好,還未開封的標(biāo)準(zhǔn)物質(zhì),可延長核查周期;
對已開封的標(biāo)準(zhǔn)物質(zhì),根據(jù)產(chǎn)品性狀以及實(shí)驗(yàn)室的條件,靈活進(jìn)行核查。
