This Standard specifies a method for testing the leaktightness of assemblies of plastics pipes and fittings with elastomeric sealing-ring socket joints or inspection openings that may be subject to diametric distortion and/or angular deflection. It includes, but is not limited to – single sockets on pipes, double sockets, sockets on fittings, and inspection openings on fittings. It is also applicable to elastomeric sealing-ring sockets made of other materials, e.g. ductile iron, intended for use with plastics piping.
