2、 a member of CEN, is obliged to publish EN 853 as a British Standard. However, attention is drawn to the fact that duringthe development of this European Standard, the UK committeevoted against its approval as a European Standard. This is due to concerns about the abrasion test method detailed inAnn
3、ex A (normative). It is the opinion of the UK committee that theabrasion test method is not reliable and gives inconsistent results.The UK participation in its preparation was entrusted to TechnicalCommittee PRI/66, Rubber and plastics tubing, hoses and hose assemblies.A list of organizations repres
