This document provides guidance on the operation of fireworks displays by professional teams of people with specialized knowledge. It is not applicable to the use of theatrical pyrotechnic articles on stage, in filming locations, or any other locations. It is not applicable to displays that involve only fireworks of categories 1, 2 and 3.

This document 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 10 mg/kg. It is generally recommended to perform a simple preliminary qualitative test to check whether a quantitative analysis is required.

This document specifies the preparation methods of the test samples for the qualitative and quantitative analysis of specific chemical substances in fireworks. The document applies to the following substances to be tested using ISO 22863 (all parts): — hexachlorobenzene; — lead and lead compounds; — arsenic or arsenic compounds; — mercury compounds; — chlorates; — white phosphorus; — picrates or picric acid; — zirconium with a particle size of less than 40 µm; — content of nitrogen in nitrocellulose.

This document 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 document, a limit of detection of 1 mg/kg (expressed as dry matter) can be achieved.

ISO/TR 21865:2017 describes the relevant responsibilities of the involved manufacturers of fireworks articles and corresponding laboratories for the application of the ISO 25947 series and the ISO 26261 series. By applying this approach, a clear separation of the responsibilities of the manufacturers and the third party laboratories is achieved in order to demonstrate the conformity to the relevant safety specifications defined in these standards.
