Foundation, British Standards Institute, German Industrial Norms and Japanese Industrial
Standards.

manufacture of pipes is Type I, Grade 1 PVC compound, and Type IV, Grade 1 CPVC
compound as stated in ASTM D-1784. Raw material used in extrusion shall contain the
specified amounts of colour pigment, stabilizers, and other additives approved by the
National Sanitation Foundation. Dimensions and Wall Thicknesses Physical dimensions,
wall thickness and tolerances of PVC and CPVC pipes meet the requirements of ASTM, DIN
and BS specifications for pipes.
Marking

manufacturer’s name or trademark, size of pipe, material designation, batch number and
month of production. There must be clear distinguishing on those products that are PVC
