A polyethylene pipe must pass 12 design and resistance test standards in order to be used as a product. These standards are:

The first test: density test: the raw material for the production of carrogate pipe must meet the ISIRI175-5 standard, and the manufactured product must follow the ISIRI9116 standard. The second test: MFI melt flow index test: raw materials used in production as well as the production pipe must include ISIRI6980 and ISIRI9116 standards. Third test: long-term cyclic resistance test: domestic and international standards ISIRI9110 and DIN1961 determine the long-term cyclic resistance of polyethylene double-walled pipe. The fourth test: short-term cyclic resistance test: the manufactured carrugite pipes must benefit from the internal standard ISIRI9116 and ISO 9969. The fifth test: the flexibility of the pipe is confirmed by ISIRI9116 and EN1446. . Sixth test: Soot amount: The percentage of spiral tube soot is determined by the domestic standard ISIRI7175-2 and ISIRI9116. Seventh test: Soot dispersion, which must be in accordance with the standards set by ISIRI7175-6 and ISIRI9116.

Eighth test: Impact test: The standard set by Iran ISIRI9116 and EN744 standard, sufficient resistance of the level against They guarantee a hit. Ninth test: Thermal return test: Carogite pipes must work according to ISIRI9116 and ISIRI7175-3 standards in order to get the thermal return approval. 10th test: The linear tensile test of Carrogate pipe, which indicates its resistance to tensile forces, is confirmed by ISIRR9116 and EN1979 standards. 11th and 12th tests: The appearance of the polyethylene pipe and the marking of the pipe must be in accordance with the internal standards of ISIRI9116.
