ISO 25947-1:2017

Overview

ISO 25947-1:2017 is an international standard developed by the International Organization for Standardization (ISO) that focuses on terminology related to fireworks in Categories 1, 2, and 3. This standard provides clear and consistent definitions for terms used in the design, construction, primary packaging, and testing of these fireworks. By standardizing the language and concepts, ISO 25947-1:2017 supports manufacturers, testers, regulators, and users in ensuring safety, compliance, and uniform understanding within the fireworks industry.

The document is part one of a series and aimed specifically at improving communication and quality assurance when handling fireworks of these three categories. It covers essential terminology such as pyrotechnic compositions, effects, components, and nonconformities, providing a foundation for product development, testing, and regulatory adherence.

Key Topics

• Firework Categories: Specifically addresses Categories 1 (indoor fireworks), 2 (garden fireworks), and 3 (display fireworks).
• Terminology Definitions: Defines critical terms such as:
  • Firework Case: The container designed to retain pyrotechnic compositions and influence firework behavior.
  • Pyrotechnic Composition: Substance or mixture producing visual, aural, or gas-evolving effects upon ignition.
  • Initial Fuse and Ignition Head: Components responsible for initiating firework function.
  • Bursting Charge and Propellant Charge: Specific pyrotechnic components causing explosions or propulsion without bursting the case.
  • Nonconformities: Classifications of defects (critical, major, minor) affecting safety or usability.
  • Net Explosive Content (NEC): The mass of explosive composition excluding ignition elements.
  • Testing Terms: Including batch tests, type tests, and acceptance quality limit (AQL).
• Packaging Concepts: Explains primary pack and selection pack terminology relevant to retail and consumer handling.
• Safety-Related Definitions: Critical for identifying hazardous conditions, such as critical nonconformities and projected debris.

Applications

ISO 25947-1:2017 is designed primarily for professionals involved in the production, quality control, testing, and regulatory oversight of fireworks in categories 1, 2, and 3. Its key applications include:

• Product Design and Manufacturing: Ensures using standardized terminology during design, construction, and quality inspections.
• Quality Assurance and Testing: Assists in defining criteria for batch testing, type testing, and interpreting nonconformities to maintain safety and performance.
• Regulatory Compliance: Provides authorities with uniform terminology for safety inspections, certifications, and enforcement of regulations.
• Consumer Safety Information: Clarifies packaging terms and product definitions that contribute to improved consumer understanding and safe handling.
• Industry Training and Documentation: Acts as a reference guide for staff training and technical documentation within the fireworks industry.

Related Standards

ISO 25947-1:2017 interacts closely with other standards to form a comprehensive framework for fireworks:

• ISO 25947-2: Defines categories and types of fireworks for Categories 1, 2, and 3.
• ISO 26261 series: Pertains to Category 4 fireworks, including higher hazard products.
• ISO 2859-1:1999: Provides sampling procedures for inspection by attributes, referenced for acceptance quality limits (AQL) and nonconformity classes.
• ISO/IEC Directives: Guide the development, maintenance, and approval of ISO standards, ensuring international collaboration and consistency.
