Describes materials, dimensions, classification, design, testing and marking for pressure and non-pressure pipes, fittings and joints made from glass reinforced thermosetting plastics with or without an aggregate filler. Applicable to pipes and associated fittings having diameters from 100 to 4000 for use at pressures up to 25 bar and intended conveying potable and non-potable water, foul sewage and storm water. Also used for conveying industrial wastes providing its suitability has been established.
