Overview
ISO 22863-16:2025 - Fireworks - Test methods for determination of specific chemical substances - Part 16: Procedure for identification of report or burst charge defines a standardized laboratory procedure to identify the type of report (bang) or burst charge used in consumer and display fireworks. Published as the first edition in 2025 by ISO/TC 264, this standard helps determine whether a charge is a perchlorate/metal, nitrate/metal, black powder, or another pyrotechnic composition through staged qualitative testing.
Key topics and requirements
- Scope: Specifies the identification procedure for report or burst charges in fireworks; part of the ISO 22863 series on chemical test methods for pyrotechnics.
- Referenced methods: Uses results from related parts of ISO 22863 for targeted tests:
- Identification logic: A decision flow (Figure 1) directs the analyst to check for metals, perchlorates and nitrates in sequence to classify:
- Perchlorate/metal compositions (metals + perchlorates)
- Nitrate/metal compositions (metals + nitrates, no other oxidants)
- Black powder / other (nitrates only and no active metal)
- Sample preparation:
- Disassembly per ISO 22863-1 and isolation of the report or burst composition.
- For mixed components, sieve the material on a 35 mesh analytical sieve and collect the screened material for testing.
- Qualitative identification:
- Follow the Figure 1 flowchart and perform separate qualitative tests for perchlorates, nitrates and metals using fresh subsamples for each assay.
- Test report requirements: Laboratory name/address, date, reference to ISO 22863-16:2025, sample description, identification methods used, results and any anomalies observed.
Applications and users
This standard is intended for:
- Independent testing laboratories performing fireworks chemical characterization
- Fireworks manufacturers and quality control teams verifying composition types
- Regulatory authorities and customs assessing compliance and potential hazards
- Event safety specialists and forensic analysts investigating incidents involving pyrotechnics
Practical uses include classification of charges for safety labeling, compliance verification, risk assessment, and support for regulatory enforcement.
