ČSN EN ISO 20342-4

This document specifies conditions and test methods for the durability of assistive products for tissue integrity (APTI) when lying down. These methods are additional to the ones in ISO 20342-1. This document is applicable to both reactive and active APTIs, such as mattresses and overlays, and includes single-patient multiple-use products. This document does not apply to single-use products. NOTE - This document is intended to help differentiate the durability characteristics between APTIs. It is not intended for determining overall performance or for ranking or scoring of such APTIs.
