This standard specifies the test method for the determination of Hexachlorobenzene (HCB) in pyrotechnic compositions by Gas Chromatography.

The limit of detection depends on the substance to be determined, the equipment used, the quality of chemicals used for the extraction of the sample, and the clean-up of the extract.

Under the conditions specified in this International Standard, a limit of detection of 1 mg/kg (expressed as dry matter) can be achieved.

This standard specifies the test method for determination of the lead content in pyrotechnic compositions of fireworks by flame atomic absorption spectrophotometry, with a minimum detection limit of 10mg/kg.

NOTE It is generally recommended to perform a simple preliminary qualitative test to check whether a quantitative analysis is required. See annex A.
