b) The pipe length shall be 3 600 mm or over. Tolerances on the length shall be zero for the minus side, and not be specified for the plus side.
Appearance
a) Pipes shall be practically straight, with the both ends practically perpendicular to the pipe axis.
b) The inside and outside surfaces of pipes shall be well-finished and free from defects that are detrimental to practical use. Especially, the inside and outside surfaces of white pipes shall be practically smooth.
c) Black pipes may be repaired by grinding or machining, provided that the thickness after repairing shall be within the given tolerances of wall thickness.
d) The surface of all repaired parts shall blend smoothly into the contour of the pipe.
e) pipes may be coated (e.g. zinc rich painting, epoxy coating, primer coating, etc.) on the outside or inside surface, or on the both surfaces.
Tests
Chemical analysis
