scope:

This part of EN 1115 specifies the characteristics of fittings made from glass-reinforced thermosetting plastics pipes (GRP) based on unsaturated polyester resin (GRP-UP) intended to be used in underground drainage and sewerage under pressure. It also specifies the test parameters for the test methods referred to in this standard. It applies to fittings intended to be used for the conveyance of surface water or sewerage under pressure, both buried and above ground, outside buildings, at temperature up to 50°C. This part specifies the dimensional and performance requirements for bends, branches, reducers, saddles and flanged adaptors made from GRP-UP, with or without thermoplastic liners. This part applies to fittings fabricated from straight pipe or moulded by filament or tape winding, or by using hand lay-up or contact moulding or hot or cold press moulding.
