standard intends to give auniform requirements for dimension, grade, colour fastness, spongeability application
to the above types of wall coverings.
Inthe formulation ofthis standard, considerable assistance hasbeen derived from EN233:1989 ‘Wallcoverings
inroll form — Specification for finished wall coverings’.
The composition of the Committee responsible for formulation.ofthis standard isgiven at Annex F.
For the purpose of deciding whether a particular requirement of this standard is complied with the final value,
