Full title and description

Fireworks — Test methods for determination of specific chemical substances — Part 1: General. This part specifies preparation methods of test samples for the qualitative and quantitative analysis of specified hazardous or restricted chemical substances in fireworks.

Abstract

ISO 22863-1:2020 defines general principles and sample-preparation procedures applicable across the ISO 22863 series for testing fireworks for specific chemical substances (for example: hexachlorobenzene; lead and lead compounds; arsenic compounds; mercury compounds; chlorates; white phosphorus; picrates/picric acid; fine zirconium; and nitrogen content in nitrocellulose). It sets out how to obtain representative test samples and prepare extracts for subsequent qualitative or quantitative analysis.

Scope

This part gives general requirements and sample-preparation methods to be used by the other parts of ISO 22863 when determining specific chemical substances in pyrotechnic compositions and finished fireworks. It applies to the listed substances (hexachlorobenzene; lead and lead compounds; arsenic and arsenic compounds; mercury compounds; chlorates; white phosphorus; picrates/picric acid; zirconium of particle size < 40 µm; and determination of nitrogen in nitrocellulose) and is intended to ensure that analyses carried out under the series are comparable and representative.

Key topics and requirements

• Definitions and terminology used across the ISO 22863 series (to ensure consistent interpretation).
• Requirements for representative sampling of pyrotechnic compositions and finished fireworks prior to analysis.
• Sample handling, storage and safety precautions to prevent contamination or degradation of analytes.
• General procedures for sample preparation and extraction that feed into specific analytical methods in subsequent parts of the series.
• References to analytical techniques and limits of detection addressed in the specific parts (e.g., GC for hexachlorobenzene, AAS/XRF/ICP for lead).

Typical use and users

Used by chemical and materials testing laboratories, regulatory agencies, fireworks manufacturers and importers, product safety and compliance teams, and forensic/explosives investigators. Typical applications include pre-market compliance testing, routine surveillance of imported fireworks, incident investigations, and research into pyrotechnic composition safety.

Related standards

ISO 22863 is a multipart series. Relevant companion parts include (examples): Part 2 — Hexachlorobenzene by gas chromatography (ISO 22863-2:2020); Part 3 — Lead and lead compounds by atomic absorption (ISO 22863-3:2020); Part 4 — Lead analysis by XRF (ISO 22863-4:2021); Part 5 — Lead analysis by ICP (ISO 22863-5:2021). These parts provide the specific analytical methods that rely on the general sample-preparation requirements of Part 1.

FAQ

Q: What is this standard?

A: ISO 22863-1:2020 is Part 1 of the ISO 22863 series — the general-methods document that specifies how to prepare and handle samples of fireworks and pyrotechnic compositions for the determination of specified chemical substances.

Q: What does it cover?

A: It covers representative sampling, sample handling and storage, safety precautions, and general extraction/preparation procedures used prior to the specific analytical tests described in the other parts of ISO 22863. It lists the substances to which the series applies (see scope).

Q: Who typically uses it?

A: Accredited testing laboratories, fireworks manufacturers and importers, regulators and product-safety professionals, and forensic/explosives investigators who need standardized sample-preparation methods for chemical testing of pyrotechnic materials.

Q: Is it current or superseded?

A: ISO 22863-1:2020 was published in February 2020 and is the first edition. ISO standards are typically reviewed every five years; consult ISO or your national standards body for the current review or amendment status.

Q: Is it part of a series?

A: Yes — it is Part 1 (general) of the ISO 22863 series. Specific analytical methods are given in subsequent parts (for example, Parts 2, 3, 4 and 5 cover hexachlorobenzene (GC), lead (AAS), lead (XRF) and lead (ICP), respectively).
