This standard specifies the structure、 classification、 requirements、 testing、 inspection rules、 marking、 packaging、 storage、 etc. of insulation pads for live working. This standard applies to insulation pads made of insulating materials for voltage levels of 35kV and below、 laid on the ground or grounded objects to protect operators from electric shock. The following normative references are essential for the application of this document. For dated references、 only the dated version applies to this document. For undated references、 the new version (including all modification orders) applies to this document. GB/T 2900.55 Electrotechnical Terminology Live Working (GB/T 2900.55-2002、 IEC 60050-651、 EQV) GB/T 14286 Terminology for Live Working Tools and Equipment (GB/T 14286-2008、 IEC 60743: 2001、 MOD) GB/T 16927.1 High Voltage Testing Techniques Part 1: General Definitions and Test Requirements (GB/T 16927.1-2011、 IEC 60060-1: 2010、 MOD) 3 Terms and Definitions Defined in GB/T 2900.55 and GB/T 14286、 and the following terms and definitions apply to this document. 3.1 Rubber materials Elastomer is a polymer material that can quickly restore its initial size and shape after repeated deformation under weak pressure、 including natural and artificial rubber、 latex and rubber polymers、 as well as thermoplastic rubber. 3.2 Certification test is a test conducted to confirm that the electrical insulation strength of the test object is higher than the specified voltage value under specified test conditions. 4. The structural insulation pad should be made of rubber or other materials、 and the upper and lower surfaces should adopt anti slip designs such as wrinkles or diamond patterns to enhance the surface anti slip performance
