The GB/T 39249-2020 standard is for rubber and plastic hoses and non-reinforced hoses (fabric reinforced). It specifies low temperature flattening test methods for evaluating the flattening performance of such hoses in low temperature environments. The standard specifies the requirements for test equipment, covering low temperature environment simulation devices and flattening test equipment. Detailed description of sample preparation, low temperature conditions setting and flattening operation procedures. By observing the deformation and damage of hoses after low temperature compression, it provides quantitative evaluation of product performance in cold environment and helps enterprises to ensure product mass.
