ISO 13477 RCP Test Machine Thermoplastics pipes for the conveyance of fluids — Determination of resistance to rapid crack propagation (RCP) 

ISO 13477 standard applicable to the assessment of the performance of thermoplastics pipes intended for the supply of gases or liquids. In the latter case, air can also be present in the pipe.

The test method for resistance to rapid crack propagation of thermoplastic pipes mainly includes small-scale steady-state test (S4 test). This test method specifies a standardized testing procedure in detail, ensuring comparability of test results between different laboratories and improving the reliability and repeatability of test data

Small scale steady-state test (S4 test)

The S4 test is a novel testing method that uses smaller sample sizes for testing, and can simulate the rapid crack propagation encountered by materials in practical applications under controlled conditions. This method is not only faster and more economical, but also more accurate in evaluating material properties

Test procedures and evaluation criteria

1, Sample preparation: Select suitable thermoplastic pipe samples and perform necessary processing, such as cutting them into specimens of the specified size.

2, Apply pressure and temperature control: Conduct tests under specified temperature and internal pressure to simulate actual usage conditions.

3, Crack monitoring and recording: Monitor the propagation of cracks through specific equipment and methods, and record relevant data.

4, Data analysis: Calculate indicators of the ability to withstand rapid crack propagation based on experimental results, such as crack propagation rate and critical pressure, to provide quantitative evaluation basis for material properties

The significance and application of the Test

Through the S4 test, the safety and reliability of thermoplastic pipes in fluid transportation applications can be evaluated, reducing the risk of sudden rupture caused by material defects, which is of great significance for ensuring the safe operation of public facilities such as water supply networks

In addition, this standard refers to advanced international testing theories and practices, promoting the exchange and mutual recognition of products and technologies at home and abroad
