First of all, the following references are indispensable for the application of the Standard:
- ISO 34-1, Rubber, vulcanized or thermoplastic: Determination of tear strength.
- ISO 37, Rubber, vulcanized or thermoplastic — Determination of tensile stress-strain properties.
- ISO 188, Rubber, vulcanized or thermoplastic — Accelerated ageing and heat resistance tests
- ISO 815-1, Rubber, vulcanized or thermoplastic — Determination of compression set.
- ISO 1431-1, Rubber, vulcanized or thermoplastic — Resistance to ozone cracking.
- ISO 7619-1, Rubber, vulcanized or thermoplastic — Determination of indentation hardness.
In Section 3, all terms and definitions are clearly explained in the document to avoid confusion. That includes bearing capacity, body, burst pressure, diameter, percentage deformation etc.
In Section 4, classification i.e. types, models & sizes are thoroughly discussed. Popular types are especially highlighted in this part of the ISO document.
Section 5 clearly explains the type of materials used to manufacture highly durable air bags. Quality rubber materials are essential, as shown.
Section 6 breaks down various tests available. From gas-tightness tests, compression tests to bearing capacity tests, there are a lot of aspects to check on.
The rest of the Standard provides a guideline for various other issues like documentation, type approval etc.
The ISO document generally provide a framework for airbag quality control. However, compliance to the Standard does not necessitate a high quality air bag. This is because there are a lot of details when it comes to fabrication skill and materials that ensures the quality of the product.
