ISO 19072-2:2019 PDF

Overview

ISO 19072-2:2019 defines test methods and general performance requirements for connector interfaces between road-vehicle pyrotechnic devices (e.g., initiators for airbags, pretensioners) and their harness connectors. The standard covers both three-way (including ground) and two-way (without ground) connection variants, plus a variant without a retainer. It specifies the mechanical, electrical and environmental tests needed to verify connector performance and safety in automotive applications.

Key topics and technical requirements

This part of the ISO 19072 series focuses on measurable performance criteria and test methods, including:

• Connector variants and annexes: sealed three-way assemblies (Annex A), two-way assemblies (Annex B), and assemblies without retainers (Annex C).
• Functional tests: visual examination, mating and unmating operations (maximum connecting/disconnecting force
