What is Slow Crack Growth Testing at ¹ú²ú͵ÅÄ×ÔÅÄ? 

Slow Crack Growth (SCG) testing evaluates how plastic pipes resist crack formation and propagation under long-term stress conditions. It specifically assesses microscopic cracks that develop slowly over time due to environmental stress cracking (ESC) or mechanical fatigue, which can eventually lead to pipe failure. At ¹ú²ú͵ÅÄ×ÔÅÄ, we conduct thorough ISO 13479 testing by subjecting PE and PEX pipes to controlled notching and hydrostatic pressure in tap water, measuring time to failure to determine crack growth resistance. This critical testing ensures your products maintain structural integrity under real-world conditions.

What can ¹ú²ú͵ÅÄ×ÔÅÄ Offer You For Slow Crack Growth  testing of plastic pipes? 

Components and materials we test:
We test all grades of PE and PEX pipes under specific pressure and temperature conditions tailored to your material type, using tap water at 80°C as the test medium. From PE 80/100 to PEX 80/100/125, each material undergoes precise testing with pressures ranging from 8.0 to 10.8 bar, ensuring a comprehensive evaluation of your specific pipe grade.

Key tests offered: 
Our comprehensive testing program includes testing a minimum of three PE or PEX pipe samples, each with controlled notching at four predetermined strategic stress points, carefully designed to simulate long-term mechanical stress and installation conditions, helping verify the pipe’s durability in actual field applications. Following the notching process, the samples are exposed to continuous hydrostatic pressure in tap water at 80°C. We measure time to failure under specific pressure conditions, with requirements varying from 500 hours for PE materials to 5,000 hours for PEX materials. 
Our tests include:  

• Notching process testing
• Hydrostatic pressure testing

Cutting-edge equipment we use:
Access one of only a handful of facilities globally equipped with 5,000 test stations, ensuring reliable and reproducible test data for your product evaluation needs.
