Annex
A (informative) Bibliography
Defines the nominal outside diameters for metric thermoplastics pipes for conveying fluids in pressure and non-pressure applications. In addition, it defines nominal pressure ratings,. minimum required strengths and overall service coefficients for thermoplastics pipes for pressure applications. Applies to smooth thermoplastics pipes of constant circular cross-section along the whole length of the pipe, whatever the method of manufacture or construction materials.
