Overview

EN ISO 14451-5:2013 (ISO 14451-5:2013) defines the requirements, test sequence and categorization for airbag gas generators - the pyrotechnic gas sources used to inflate vehicle airbags. This European adoption by CEN applies to type tests for pyrotechnic articles for vehicles and excludes articles containing military explosives or commercial blasting agents (except black powder or flash composition). The standard supports conformity with EC Directive 2007/23/EC for pyrotechnic articles.

Key Topics and Requirements

• Scope and applicability
  • Applies to airbag gas generators and to type testing only.
  • Not applicable to military explosives or commercial blasting agents (with noted exceptions).
• Design verification and documentation
  • Requires complete documentation as referenced in ISO 14451-2 test-method requirements.
• Mandatory tests and acceptance criteria
  • Drop test: no ignition; no spill out of pyrotechnic composition.
  • Vibration & temperature test: no ignition; no spill out.
  • Thermal humidity cycling test: no ignition.
  • Electrostatic discharge (ESD) test: no ignition; if igniters are already tested to ISO 14451-8, the ESD requirement for the generator may be considered satisfied.
  • Fire test: specified heating rate of 50 K/min; generator must be engulfed by flames in specified positions (tubular, disc or equivalent); acceptance criteria limit foreseeable fragmentation and hazards.
  • Tank test and functioning test: defined in Clause 4.8–4.9 (see standard for full criteria).
• Test matrix and categorization
  • Clause 5 provides the test matrix to determine applicable tests.
  • Clause 6 defines categorization criteria for airbag gas generators based on test outcomes.

Applications and Users

Who uses EN ISO 14451-5:2013:

• Automotive OEMs and suppliers designing or sourcing airbag gas generators
• Safety engineers and R&D teams working on passive restraint systems
• Accredited test laboratories performing type tests on pyrotechnic articles for vehicles
• Regulatory and conformity-assessment bodies demonstrating compliance with EU Directive 2007/23/EC
• Quality and safety managers responsible for component certification and categorization

Practical value:

• Ensures consistent testing requirements and acceptance criteria for airbag inflator safety
• Helps manufacturers classify generators into safety categories and document conformity
• Reduces risk by standardizing tests for ignition, leakage, ESD resistance and fire behaviour
