ISO 15494-2015 pdf free.Plastics piping systems for industrial applications一Polybutene (PB), polyethylene (PE), polyethylene of raised temperature resistance ( PE- RT), crosslinked polyethylene (PE-X), polypropylene (PP) – Metric series for specifications for components and the system. ISO 15494 specifies the characteristics and requirements for components such as pipes, fittings, and valves made from one of the following materials intended to be used for thermoplastics piping systems in the field of industrial applications above and below ground: — polybutene (PB); — polyethylene (PE); — polyethylene of raised temperature resistance (PE-RT); — crossli nked polyethylene (PE-X); — polypropylene (PP). NOTE 1 Requirements for industrial valves are given in this International Standard and/or in other standards. Valves are to be used with components conforming to this International Standard provided that they conform additionally to the relevant requirements of this International Standard. This International Standard is applicable to either PB, PE, PE-RT, PE-X, or PP pipes, fittings, valves, and their joints and to joints with components of other plastics and non-plastic materials, depending on their suitability, intended to be used for the conveyance of liquid and gaseous fluids as well as solid matter in fluids for industrial applications such as the following: — chemical plants;…
