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 For undated references, the latest version (including all modification orders) applies to this document. GB/T 2812 Test Methods for Safety Helmets GB 12011 Foot Protection Electrical Insulated Shoes GB/T 16927.1 High Voltage Test Techniques Part 1: General Definitions and Test Requirements GB/T 17889.2 Ladders Part 2: Requirements, Tests and Markings GB21146. Personal Protective Equipment Occupational Shoes GB 26861 Electric Power Safety Work Regulations High Voltage Test Room Part DL/T 740 Capacitive Tester DL/T976 Live Working Tools Preventive Testing Regulations for Devices and Equipment DLT 1209 Technical Requirements for Climbing Operations and Protective Equipment in Substations - Terms and Definitions - The following terms and definitions apply to this standard. 3.1 Electric 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: Inspection, testing, or testing conducted to identify potential hazards in electrical safety equipment and prevent equipment or personal accidents. The 4 categories of electrical safety equipment can be divided into four categories: personal protective equipment, insulation safety 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 DLT976. 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
