本文件规定了通过特定显色反应和电感耦合等离子体发射光谱法（ICP-OES）测定烟火成分中粒度小于40μm的锆的存在和含量的定性和定量分析方法，最低检测限为100 mg/kg。 应用ISO 25947-5时，需要测定粒度小于40μm的锆的存在。如有必要，定量分析可能会带来补充信息。

This document specifies the qualitative and quantitative analysis methods for the determination of the presence and content of zirconium with a particle size of less than 40 μm in pyrotechnic compositions by specific colour-rendering reactions and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), with a minimum detection limit of 100 mg/kg. The determination of the presence of zirconium with a particle size of less than 40 μm is required for application of ISO 25947-5. Quantitative analysis may bring complementary information if necessary.
