ActivePlastics piping and ducting systems—Thermoplastics pipes—Determination of ring flexibility
塑料管道系统 热塑性塑料管材 环柔性的测定
Application Summary AI generated
This standard specifies a test method for determining the ring flexibility of thermoplastics pipes, measuring their ability to deform under load without cracking or failing. It is applied in the quality control and design validation of plastic piping systems used in underground drainage, sewerage, and cable ducting, where pipes must withstand soil and traffic loads. Manufacturers and testing laboratories use this standard to ensure pipes meet mechanical performance requirements for buried or structural applications.
