ISO 22863-9:2021 discusses fireworks. ISO 22863-9 specifies the test method for the determination of the mercury content in pyrotechnic compositions by hydride generation atomic fluorescence spectrometry.
ISO 22863-9 on mercury content in pyrotechnics is useful for:
Mercury is used as colourant in the fireworks which produces red colour.
ISO 22863-9 provides the test method for the determination of the mercury content in pyrotechnic compositions by hydride generation atomic fluorescence spectrometry which will help you use mercury in the specific limit to produce fireworks with ensures the safety of the user.
