The checks include:Pipes• appearance • dimensional accuracy • pressure• melt-flow index• heat reversion.Fittings• appearance• dimensional accuracy• appearance and dimensional stability after heating to 60°C – 110°C • melt-flow index.1.7 A label bearing the BBA identification mark incorporating the number of this Certificate is attached to each pipelength and fitting or to each crate of pipes or box of fittings.2 Delivery and site handling2.1 Pipes are supplied in lightweight, reinforced brackets and should be stored on a flat surface in stacks not morethan 1.7 m high and away from heat sources, to avoid distortion.2.2 The pipes are marked with:• material HDPE • outside diameter and wall thickness • BS EN 1519-1 : 2000• manufacturer’s mark.2.3 The fittings are supplied in boxes which are marked with the associated outside diameter and reference code.Page 11 of 16
