This article relates to ISO 16840-6:2015
Overview
This standard covers the means of generating aging effects in a seat cushion that reproduce those seen in use. It provides methods of determining changes in the physical and mechanical properties of seat cushions based on their age and use. It 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.
