《GB/T 28643-2012饲料中二噁英及二噁英类多氯联苯的测定同位素稀释-高分辨气相色谱/高分辨质谱法》由TC76（全国饲料工业标准化技术委员会）归口，主管部门为国家标准化管理委员会。

Scope

This standard specifies the determination of 17 2,3,7,8-chloro-substituted polychlorinated dibenzodioxins (PCDDs) and polychlorinated dioxins in feed by isotope dilution-high resolution gas chromatography/high resolution mass spectrometry. Benzofurans (PCDFs) (hereinafter referred to as PCDD/Fs) and 12 kinds of dioxin-like polychlorinated biphenyls (DL-PCBs) (see Table A.1 and Table A.2). This standard applies to feed raw materials, compound feeds, concentrated feeds, concentrate supplements, additive premixed feeds and feed additives. The detection limits of PCDD/Fs and DL-PCBs in feed analyzed by this standard method are shown in Table B.1.
