The HG/T 5229-2017 "Hot Air Aging Box" standard specifies the structure and basic parameters, technical requirements, test methods, inspection rules, signs, Encasement, transportation and storage of hot air aging boxes used for aging tests of vulcanized rubber or thermal plasticity rubber. The standard is suitable for evaluating the aging performance of rubber materials in high temperature environments to ensure the Reliability and durability of products during use. The aging box is mainly composed of studios, sample racks, forced ventilating devices, heating thermostatic Control systems and temperature display devices to provide a stable aging environment. The standard also refers to relevant national standards, such as general technical conditions for rubber testing equipment, to ensure that the design and use of aging boxes comply with industrial standards and safety requirements.
