Accelerate your product certification. Get precise, reproducible test data for PE pressure pipes in sub-zero conditions. Our advanced S4 testing validates your products' performance against rapid crack propagation, streamlining your certification process and supporting faster market entry. Meet ISO 13477 requirements through independent verification that advances your business goals.

What is Rapid Crack Propagation Testing at ²ÝÁñÉçÇø?  

Rapid crack propagation (RCP) testing investigates the sudden fractures that can occur in thermoplastic pressure pipes, especially polyethylene (PE), under specific stress and low temperatures. In critical infrastructure, particularly in sub-zero conditions, it is crucial to understand a material's resistance to RCP to ensure long-term safety and performance.  

At ²ÝÁñÉçÇø, we perform ISO 13477-compliant, Small-Scale Steady-State (S4) testing to evaluate your products' resistance to RCP. This efficient, small-scale method delivers reproducible results that aid in product development, certification, and performance evaluation, serving as a faster and more cost-effective alternative to full-scale testing. 

What Can ²ÝÁñÉçÇø Offer You For ISO 13477 Rapid Crack Propagation Testing?   

Components and materials we test 

Our testing program focuses on Polyethylene (PE) Pressure Pipes, where we evaluate crack propagation, particularly in sub-zero conditions, to ensure optimal performance and long-term durability. We also test a broad range of Thermoplastic Pipes, including Polypropylene and PVC, assessing their crack initiation and propagation characteristics under various conditions. Additionally, we conduct thorough testing on Industry-Relevant Resins, supporting manufacturers in refining their formulations to meet industry standards and deliver products that stand the test of time. 

Key tests offered 
Access critical testing data through our comprehensive S4 test program, designed to ensure reliability and performance of your products in demanding conditions:  

• Critical Pressure Test: This test determines the pressure at which RCP occurs, helping you understand your material’s pressure limits.  
• Critical Hoop Stress Test: We assess the hoop stress required for crack initiation and propagation, ensuring that your pipes and materials can withstand internal stresses in real-world applications.  
• Critical Temperature Test: Our testing evaluates the temperature threshold at which rapid crack propagation becomes a risk, particularly important for applications in sub-zero environments. 

Methods and solutions offered 
We utilize advanced testing methods to ensure the highest accuracy and reliability for your materials, helping you make informed decisions regarding performance and certification.
