Full title and description

Fireworks — Test methods for determination of specific chemical substances — Part 11: Phosphorus content by inductively coupled plasma optical emission spectrometry (ICP-OES). This part of ISO 22863 specifies a quantitative laboratory method for measuring the phosphorus content of pyrotechnic compositions used in fireworks using ICP‑OES.

Abstract

This standard specifies the test method for determination of phosphorus content in firework compositions by inductively coupled plasma optical emission spectrometry (ICP‑OES). It applies to fireworks (excluding certain small consumer articles such as Christmas crackers, party poppers or snaps) and includes notes on hazards related to white phosphorus and references relevant conditioning tests.

Scope

Specifies a laboratory procedure to determine total phosphorus content in pyrotechnic compositions intended for fireworks using ICP‑OES. The scope covers sample preparation and analytical measurement for compositions covered by the ISO 22863 series and excludes some small consumer articles (e.g., Christmas crackers, party poppers, snaps). The standard also notes safety considerations where white phosphorus may be present and cross‑references conditioning and safety tests in related ISO documents.

Key topics and requirements

• Principle: quantitative determination of phosphorus by ICP‑OES after suitable sample preparation/digestion.
• Required reagents, calibration and instrument performance checks for reliable ICP‑OES measurement.
• Sample preparation and digestion procedures appropriate for pyrotechnic matrices (to ensure complete phosphorus recovery).
• Calculation and expression of results (reporting units, limits of detection/quantification and repeatability considerations).
• Notes on safety and special cases — in particular the potential presence of white phosphorus and related hazard considerations (cross‑referenced tests such as thermal conditioning in ISO 25947‑4).

Typical use and users

Used by analytical laboratories, fireworks manufacturers, product safety and compliance testing bodies, regulatory agencies, customs laboratories and test houses that evaluate pyrotechnic compositions for safety and conformity. It is intended for technical specialists familiar with ICP‑OES and handling of energetic/pyrotechnic materials.

Q: What does it cover?

A: It covers sample preparation (as applicable within the ISO 22863 series), digestion, instrumental measurement by ICP‑OES, calibration and calculation/reporting of phosphorus results for fireworks compositions, with notes on safety and excluded small consumer articles.

Q: Who typically uses it?

A: Accredited and commercial test laboratories, fireworks manufacturers for quality control, regulatory and enforcement laboratories, and any organization performing compositional safety testing of pyrotechnic products.
