Foreword
GB/T 33588 "Lightning Protection System Components (LPSC)" is divided into 7 parts.
---Part 1.Requirements for connectors;
---Part 2.Requirements for air-termination, down conductor and grounding electrode;
---Part 3.Requirements for Isolation Discharge Gap (ISG);
---Part 4.Fastener requirements for conductors;
---Part 5.Requirements for grounding electrode detection boxes and grounding electrode seals;
---Part 6.Requirements for Lightning Strike Counter (LSC);
---Part 7.Requirements for grounding resistance-reducing materials.
This part is Part 7 of GB/T 33588.
This section was drafted in accordance with the rules given in GB/T 1.1-2009.
This part replaces GB/T 33588.7-2017 ``Lightning Protection System Components (LPSC) Part 7.Requirements for Grounding Resistance Reduction Materials'',
Compared with GB/T 33588.7-2017, the main technical changes are as follows.
---Added test steps for resistivity measurement of powder grounding resistance reduction materials (see 5.3.3);
---Added requirements for flat steel, round steel and galvanized steel for grounding body samples (see 5.9.1);
--- Deleted the "corrosion test of buried ground resistance reduction materials to steel grounding bodies" (see 5.9.3 of the.2017 edition);
--- Added "Type test procedure for grounding resistance-reducing materials" (see Appendix A).
This part uses the redrafting method to refer to IEC 62561-7.2018 ``Lightning Protection System Components (LPSC) Part 7.Ground Resistance Reduction
"Material Requirements" is compiled, and the degree of consistency with IEC 62561-7.2018 is not equivalent.
