23、ements of this standard based on continuing survaillance which should be coupled with an assessment of a suppliers quality system against the appropriate standard, .e. EN IS0 9001. 1 Scope This European Standard specifies the requirements, sampling, test methods and conditions of delivery for seamle

24、ss round copper tubes covered with solid plastics material. It is applicable to tubes intended for: - distributing networks for hot water and cold water; - hot water heating systems (temperature not exceeding 95 OC) including underfloor heating systems; - domestic gas and liquid fuel distribution. N

25、OTE The primary purpose of the covering is to protect the copper tube against external corrosion in service. In addition, the covering can give some protection against impact and mechanical loading during transportation, installation and operation. Coverings whose primary objective is thermal insula
