| Resumen: | This document specifies two methods for determining the air flow value of flexible cellular polymeric materials: Method A, for conventional types of flexible cellular polymeric material; Method B, for all types of flexible cellular polymeric material, but especially for materials with a low permeability to air. For method B two methods are specified in this document: Method B1: with manual measurement; Method B2: with automatic measurement. |
