Decision C700 to adopt a new work item for the revision of EN 622-4.

Scope

This document specifies the requirements for softboards as defined in EN 316, with a density from 230 kg/m³ to 400 kg/m³.

The values listed in this document relate to product properties but they are not characteristic values to be used in design calculations.

NOTE Panels which are intended for use exclusively as thermal insulating products are covered by EN 13171.

Purpose

The imitation of fibre boards of type SB.LS and SB.HLS to short­term and instantaneous load duration will be deleted and the denomination of those boards therefore will be changed from SB.LS to SB.L and SB,HLS to SB.HL, respectively. This is necessary to include these board types in EN 1995­1­1 for load bearing purpose.
