GB/T 13397-2024 Technical specification for silver-metaloxide electrical contacts by alloy internal oxidation method 1 Scope This document specifies the requirements, inspection rules, marking, packaging, transportation and storage of silver metaloxide sheet electrical contacts (hereinafter referred to as "electrical contacts") such as silver-cadmium oxide, silver-zinc oxide and silver-copper oxide manufactured by alloy internal oxidation process (including internal oxidation process and pre-oxidation process), and describes the corresponding testing methods. This document is applicable to silver metaloxide sheet electrical contacts such as silver-cadmium oxide, silver-zinc oxide and silver-copper oxide manufactured by alloy internal oxidation process, which are mainly used in various low-voltage switching appliances. 2 Normative references The following documents contain requirements which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies.
