Scope: This document specifies the classification and marking, requirements, test methods, inspection rules, marking, packaging, transportation and storage, installation, commissioning and acceptance of solid heat storage devices (hereinafter referred to as "solid heat storage devices") with an access voltage of 10 kV and 35 kV. This document applies to intelligent electrically controlled heat storage devices with a rated working voltage of 10 kV and 35 kV, a rated input power of more than 1 MW, and a solid heat storage medium in civil buildings, industrial buildings, and other heat demand fields, where the heat output medium is hot water, hot air, or steam. The key content discussed includes the following: Chapter 3 defines nine basic terms: solid heat storage device, solid heat storage material, heat output medium, heat transfer medium, heat storage body, heat storage body temperature, effective heat storage capacity, effective heat release capacity, and thermal efficiency. Chapter 4 specifies the classification and marking requirements for solid heat storage devices. Chapter 5 stipulates the design, raw materials, manufacturing and assembly, appearance, thermal efficiency, maximum surface temperature of easily accessible parts, tightness of the piping system, electrical control system, electrical safety, and noise requirements for solid heat storage devices. Chapter 6 prescribes the test conditions, manufacturing and assembly, appearance, thermal efficiency, maximum surface temperature of easily accessible parts, tightness of the piping system, electrical control system, electrical safety, and noise test methods for solid heat storage devices. Chapter 7 defines the types of inspection rules, on-site inspection, and type inspection rules, as well as the judgment rules for inspection. Chapter 8 stipulates the requirements for marking, packaging, and accompanying documents, transportation, and storage. Chapter 9 specifies the requirements for insta
