Bibliography

Describes apparatus, test methods, and disclosure requirements for generating aging effects in a seat cushion that reproduce those seen in use.

This part of ISO16840 specifies apparatus, test methods, and disclosure requirements for generating aging effects in a seat cushion that reproduce those seen in use. It also provides methods of determining changes in the physical and mechanical properties of seat cushions based on their age and use. This part of ISO16840 provides a set of tests that simulate wear and tear, which can be useful to validate warranty claims and to provide information about product, life, and performance limitations associated with product use.
