Every shipment shall pass below testing before shipping, to make sure top quality !

A. Pipes

1. Vicat Softening Temperature Measurement:

Conforming to G/T8802 or ASTM D1525 or ISO 306 standard; minimum Vicat Softening Temperature for UPVC pipes shall be not less than 79℃ and for CPVC pipes it shall not less than 110℃;  

 

2. Drop Hammer Test: Conforming to G/T6112 standard; for testing the maximum impact data of the pipes.

 

3. Tensile Strength Test: Conforming to G/T8804 or ASTM D638 or ISO 527 standard for Tensile Stress, Yield Stress and Elongation Rate on the tested pipes.

 

4. Hydrostatic and Burst pressure: ANSI pipes shall be tested according to ASTM D1785 standard.; The pipes of local specification shall be tested conforming to GB/T15560-1995 standard.

 

5. Longitudinal Reversion: Test shall be conducted conforming to GB/T6671-2001, firstly the samples heated up to 150±2℃ and then measure the longitudinal reversion dimension, which should be not over 5%.

 

6. Dichloromethane Immersion: The test shall be conducted conforming to GB/T13526 standard, after dichloromethane immersion, then measure and investigate the transformation of cutting surface ﹑damage condition inside and outside of the pipe and the variation of its area.

 

B. Fittings

 

1. Vicat Softening Temperature Test: The test shall be conforming to G/T8802 or ASTM D1525 standard; it requires the UPVC temperature shall be not less than 74℃ and CPVC shall be not less than 103℃.

 

2. Hydrostatic Pressure Test: connect with pipe of same grade and type, test its compression resistance.

 

3. Falling Weight Test: The test shall be conducted conforming to G/T8801 or ASTM D5628 standard, preserved the test samples in freezer 0±1℃ for 30 minutes and then falling the samples freely from five different azimuth at the demand height(D≤75mm,at 2m, D＞75mm, at 1m),the fitting should be in good condition after test.

 

4. Hot Oven Test: The test shall be conducted conforming to GB/T8803-2001 standard, The samples shall be stored in oven for temperature up to 150±2℃. No cracking, bubbling, split at the molding line or other surface damage shall be found.

 

5. Drop Hammer Test: The test shall be conducted conforming to sG/T6112 standard, check up the maximize impact of fitting.

 

C. Valves

 

1. Vicat Softening Temperature Test: The test shall be conforming to G/T8802 or ASTM D1525 standard; the minimum temperature for the UPVC valves not less than 74℃ and for CPVC valves it shall be not les than 103℃.EE: XRW-300 Thermal deformation, Vicat softening temperature tester.

 

2. Hydrostatic Pressure Test : connect with pipe of same grade and type, test its compression resistance.
