Methods of testing plastics - Thermoplastics pipes, fittings and valves - Thermoplastics pipes for the conveyance of fluids - Nominal outside diameters and nominal pressures - Metric series
This part of ISO 161 specifies the nominal outside diameters for metric thermoplastics pipes for the con-veyance of fluids in pressure and non-pressure appli-cations. It also specifies nominal pressure ratings, minimum required strengths and overall service (design) coefficients for thermoplastics pipes for press-ure applications.
It is applicable to smooth thermoplastics pipes of con-stant circular cross-section along the whole length of the pipe, whatever their method of manufacture or material of construction.
