With increased demand for evaluation of oxidative resistance to chlorinated water, Element offers extensive testing capacity to demonstrate the chlorine resistance of plastic piping materials and systems. We apply ASTM F2023 (PEX, PE-RT), ASTM F2263 (PE), and ASTM F3497-21 (PP) for testing and evaluation of the long-term chlorine performance.

Chlorine resistance testing is part of Element's global Plastic Pipes & Fittings Testing program, provided to resin manufacturers, pipe extruders, certification bodies and utility companies worldwide, where independent, reliable and reproducible test data is required for product classification and life time evaluation.

Evaluation of oxidative resistance to hot chlorinated water 

Chlorine resistance tests are performed to evaluate the oxidative resistance of piping materials and systems to chlorinated water. While many pipe materials have proved to be resistant to degradation, the ageing process can accelerate under more aggressive conditions with significant impact on lifetime and durability. For example, the common use of chlorine for disinfection purposes is increasing the importance of evaluating chlorine resistance of piping materials and systems.

Our accredited facility generates reliable and reproducible chlorine resistance data for an extensive range of pipe dimensions and assemblies with a capacity of 200 chlorine test stations, allowing our customers to use the test results for certification to “ANSI NSF”.

Testing to ASTM F2023, ASTM F2263 and ASTM F3497-21

For chlorine resistance tests Element applies the standard methodology of ASTM F2023 (PEX, PE-RT), ASTM F2263 (PE), and ASTM F3497-21(PP) for testing and evaluation of the long term chlorine performance. These methods can also be used for other piping materials.

Test principle

The testing is conducted under accelerated conditions at elevated temperatures and pressures. The most common and accepted approach is to perform exposure under ”worst case” conditions.

Standard test conditions

• Dimensions: up to OD 63 mm (2” US)
• Capacity: >200 pipe samples
• Temperatures: 40-120 °C
• Chlorine concentration: 0.5 – 4.3 ppm (mg/dm3), others are available upon request
• pH: 6.8 is set as standard (others on request)
• Flow rate: 54 dm3/h (others are available upon request)
