GB/Z 28820.2-2012 is the second part of the long-term radiation aging standard for polymers, focusing on aging prediction procedures at low dose rates. The standard specifies the methods, steps and related requirements for predicting polymer aging under low dose rate radiation conditions. Through scientific calculation models and experimental procedures, it provides technical guidelines for evaluating the aging trend and service life of polymers in low dose rate radiation environments.
