This document specifies methods for measurement and/or determination of the dimensions of plastics pipes and fittings and the accuracy of the measurement. It specifies procedures for measuring angles, diameters, lengths, squareness and wall thicknesses for the purposes of checking conformity to geometric limits. NOTE This document is using metric units. However the procedures and tolerances are applicable to other units by using appropriate conversion factors.
