What is ISO 19072‑2 - Performance requirements of pyrotechnic devices about?
ISO 19072 is a series of international standards on road vehicles that discusses an increasing number of pyrotechnic devices contributing to occupant safety in vehicles (for example, frontal and side airbags, safety belt pre-tensioner, etc.).
ISO 19072‑2 is the second part of the series of documents that specifies the performance criteria and requirements of a three-way connection interface, including ground connection, linking the pyrotechnic device and harness connector built into a road vehicle.
NOTE: Performance criteria and requirements are defined for:
- A sealed variant
- Two-way (without ground) variant
- Variant without a retainer
Who is ISO 19072‑2 - Performance requirements of pyrotechnic devices for?
ISO 19072‑2 on pyrotechnical devices is useful for:
- Designers, manufacturers and suppliers of pyrotechnic devices
- Mechanical engineers
- Road vehicles designers and manufacturers
Why should you use ISO 19072‑2 - Performance requirements of pyrotechnic devices?
The pyrotechnic device is an integral part of the vehicle to validate security access when in a critical scenario. ISO 19072‑2 provides the functional characteristics of mated connectors of pyrotechnic devices to perform a visual examination and testing mating and unmating sequences.
ISO 19072‑2 provides guidance regarding the test methods to check resistance to tensile and compressive force between the connector and squib holder equipped with initiator and retainer.
ISO 19072‑2 navigates you through the test procedure to ensure the mechanical strength of the retainer in the squib holder.
For a sealed variant of the pyrotechnic device/initiator harness connector assembly, the test sequence is specified in ISO 19072‑2.
Moreover, ISO 19072‑2 lets you design and manufacture high-quality pyrotechnic devices for road vehicles in order to test the performance of vehicles in critical situations and provide safety measures. In this manner, you could ensure the quality, reliability as well as performance of pyrotechnic devices.
What’s changed since the last update?
BS ISO 19072‑2:2019 supersedes BS ISO 19072‑2:2013. BS ISO 19072‑2:2019 includes some technical changes with respect to BS ISO 19072‑2:2013. These include:
- Force and torque requirements for straight connectors
- Force and torque requirements for right-angle connectors
- Includes key, signal contact resistance
- Maximum signal contact resistance
- Maximum contact resistance between ground and squib holder
