Introduction It is recommended that tubes manufactured to this European Standard are certified as conforming to the requirements of this standard based on continuing surveillance which should be coupled with an assessment of a supplier's quality management system against EN ISO 9001. NOTE Appropriate precautions should be taken if applying insulating material because it could be detrimental to the copper tube. SIST EN 12735-1:2010
