Ever seen a Cracked Round Bar (CRB) test? In this video, we showcase in slow motion how a polyethylene test specimen fails under cyclic loading. The CRB test is specifically designed to simulate the slow crack growth (SCG) process in polyethylene (PE) and delivers faster results than traditional methods such as PENT and FNCT.
Kiwa is a global expert in SCG testing and conducts the CRB test in accordance with ISO 18489. This test is performed at operating temperature and without accelerating agents such as detergents, making it highly representative of real-world conditions.
