Fireworks - Test methods for determination of specific chemical substances - Part 6: Zirconium with a particle size of less than 40 µm by inductively coupled plasma optical emission spectrometry (ICP-OES)
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.
