It supersedes BS EN 853:1997, which is withdrawn.BSI, as a member of

2、CEN, is obliged to publish EN 853 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted against its approval as a European Standard. This is due to concerns about the abrasion test method detailed in Annex A (norm

3、ative). It is the opinion of the UK committee that the abrasion test method is not reliable and gives inconsistent results.The UK participation in its preparation was entrusted to Technical Committee PRI/66, Rubber and plastics tubing, hoses and hose assemblies.A list of organizations represented on
