This standard specifies the items、 cycles、 requirements、 and testing methods for periodic preventive testing of power safety tools and instruments. This standard is applicable to the preventive testing of electrical safety tools and instruments. The following normative references are essential for the application of this standard. For dated references、 only the dated version applies to this document. All undated references to the latest version of the document (including all amendments) are applicable to this document. GB/T 2812 Safety and Preconditioning Methods GB 12011 Foot Protection、 Electrical Insulated Shoes GB/T 16927.1 Butong Jade Test Technology Part 1: General Definitions and Test Requirements GB/T 17889.20 Part 2: Requirements、 Tests and Markings GB 21146 1 Non protective Equipment Occupational Shoes GB 26861 Electrical Subsafety Work Regulations High Voltage Laboratory Part DLT 740 Capacitor Type Inspectors DLT976 Preventive Testing Regulations for Devices and Equipment DLT 1209 Technical Requirements for Climbing Operations and Protective Equipment in Substations - Terminology and Definitions - The following terms and definitions are applied to this standard. 3.1 Electrical safety tools and devices are materials、 instruments、 or devices used to prevent electric shock、 mechanical injury、 high-altitude fall、 and other injuries and occupational hazards among power operators. 3.2 Preventive test The inspection、 testing、 or testing of electrical safety tools in order to detect hidden dangers and prevent equipment or personal accidents. The 4 categories of electrical safety equipment can be divided into four categories: personal protective equipment、 insulation safety king equipment、 climbing equipment、 and warning signs、 as follows: a) Personal protective equipment: refers to safety equipment used to protect the human body from acute injury. b) Insulation safety tools: can be divided into basic insulation safety tools (including insulation safety tools for live working) and auxiliary insulation safety tools、 as follows: 1) Basic insulation safety tools: refers to tools that can directly operate live devices、 come into contact with or may come into contact with live objects、 some of which are special insulation safety tools for live working. Preventive testing of insulation safety tools for live working is carried out according to DLT 976. 2) Auxiliary insulation safety tools: refers to safety tools with insulation strength that cannot withstand the working voltage of equipment or lines、 and are only used to enhance the security function of basic insulation safety tools to prevent contact voltage、 step voltage、 leakage current、 and arc from causing harm to operators
