17、f this specification.6. General Requirements6.1 WorkmanshipThe pipe and fittings shall be homog-enous throughout and essentially uniform in color, opacity,density, and other properties. The inside and outside surfacesshall be semimatte or glossy in appearance (depending on thetype of plastic) and fr

Holesdeliberately placed in perforated pipe are acceptable. Thesurface sh
19、all be free of excessive bloom. Bloom or chalkingmay develop in pipe exposed to the direct rays of the sun(ultraviolet radiant energy) for extended periods; consequently,these requirements do not apply to pipe and fittings afterextended exposure to direct rays of the sun.NOTE 2Wall thickness may var
