SIST EN ISO 14451-6:2013 PDF

Overview

EN ISO 14451-6:2013 (ISO 14451-6:2013) - published by CEN in conjunction with ISO - specifies the requirements, test sequence and categorization for airbag modules as part of the ISO 14451 series on pyrotechnic articles for vehicles. The standard applies to type tests and sets acceptance criteria and a test matrix for design verification, environmental and safety performance. It does not apply to items containing military explosives or commercial blasting agents (except black powder or flash composition).

Key topics and technical requirements

• Scope and applicability
  • Type testing of complete airbag modules; excludes military explosives.
  • Documentation requirements referenced to ISO 14451-2 (design and documentation completeness).
• Test sequence and matrix (Clause 5)
  • Specifies the order and combination of tests required for categorization (see Clause 6).
• Primary test types and acceptance criteria
  • Drop test (ISO 14451-2, 4.2): Acceptance - no ignition, no spill out of pyrotechnic composition.
  • Vibration and temperature test (ISO 14451-2, 4.3): Acceptance - no ignition, no spill out.
  • Thermal humidity cycling and functioning test (ISO 14451-2): Acceptance - no ignition.
  • Electrostatic discharge (ESD) test (ISO 14451-2, 4.5): Acceptance - no ignition.
  • Fire test (ISO 14451-2, 4.6): Heating rate specified 80 K/min; acceptance - only foreseeable fragmentation or opening allowed; burner orientation must engulf the module cross-section where pyrotechnic elements reside.
  • Functioning test (ISO 14451-2, 4.9): Verifies correct deployment/function after environmental exposure.
• Categorization (Clause 6)
  • Defines categories based on test outcomes and compliance with acceptance criteria.
• Conformity and regulatory linkage
  • Annex ZA relates the standard to EC Directive 2007/23/EC for placing pyrotechnic articles on the market, offering a presumption of conformity when implemented.

Applications

• Product type approval and safety validation of airbag modules for passenger cars, curtain modules and other vehicle restraint systems.
• Development and verification during design, qualification testing, supplier assessment and regulatory compliance activities.
• Basis for certificates from independent test laboratories and evidence for OEM procurement specifications.

Who should use this standard

• Airbag and restraint-system manufacturers
• Automotive OEM safety and compliance engineers
• Third‑party test laboratories performing type tests
• Regulatory authorities and certification bodies
• Procurement and quality managers specifying supplier acceptance criteria

Related standards
