BS EN ISO 844. Rigid cellular plastics. Determination of compression properties
|Standard number:||19/30381894 DC|
- 83.100 Cellular materials
This document specifies methods for determining the compressive strength and corresponding relative deformation; the compressive stress at 10 % relative deformation; and the compressive modulus of rigid cellular plastics.
Two methods are given. Procedure A employs crosshead motion for determination of nominal compressive properties. Procedure B employs displacement measuring device (including contact and optical types).
