    Abstract - (Show below) - (Hide below)

    Specifies general requirements and application classes for small diameter pipes (up to 67 mm) in alternative metric sizes standardized for plastics pipes or copper tubes. Gives performance requirements for associated fittings and is supported by supplementary Parts for pipes of specific materials and a separate installation specification.
