a) Added the terms "impact current" and "surge" and their definitions (see 3.13, 3.14);

b) The classification of lightning strike counters has been changed (see Chapter 4, Chapter 4 of the 2020 edition);

c) Added test requirements for the applicability of tests performed in previous versions (see 6.1);

d) Added test methods for documents and installation instructions (see 6.2);

e) The identification test has been changed (see 6.3, 6.7 of the 2020 edition);

f) The requirements for corrosion resistance test (metal parts) have been changed (see 6.5, 6.3 of the 2020 edition);

g) The figure of "Pendulum impact test device" was deleted (see Figure 1 of the 2020 edition);

h) Added the normative appendix "Applicability of tests performed according to previous versions" (see Appendix D).

This document is equivalent to IEC 62561-6:2023 "Lightning protection system components (LPSC) Part 6: Lightning stroke counters (LSCs) Require".

The following minimal editorial changes were made to this document.

--- Notes were added in 6.1 to facilitate understanding and application;

---Correct "after the test in 5.3.2" in 6.3.2 to "after the test in 6.3.1".

Introduction

GB/T 33588 "Lightning protection system components (LPSC)" aims to establish the lightning protection system components designed and installed according to the IEC 62305 series of standards.

The requirements and test methods for various components used in the life protection system (LPS) are intended to consist of eight parts.

--- Part 1: Requirements for connectors. The purpose is to establish the requirements and test methods for metal connectors in lightning protection systems.

--- Part 2: Requirements for lightning terminals, down conductors and grounding electrodes. The purpose is to establish the requirements for the metallic conductors that constitute lightning terminals and down conductors.

Requirements and test methods for metal grounding electrodes (non-"natural" conductors) and metal grounding electrodes that constitute the grounding system.

--- Part 3: Requirements for Isolating Spark Gaps (ISGs). The purpose is to establish the requirements for isolating spark gaps in lightning protection systems and test methods.

--- Part 4: Requirements for conductor fasteners. The purpose is to establish the metal fasteners used to fix and support air terminals, down conductors and grounding devices.

Requirements and test methods for fasteners for metal and non-metallic conductors.

--- Part 5: Requirements for grounding electrode detection boxes and grounding electrode seals. The purpose is to establish grounding electrode detection boxes installed underground Requirements and test methods for terminal boxes and earthing electrode seals.

--- Part 6: Requirements for lightning strike counters (LSCs). The purpose is to establish the requirements and test methods for lightning strike counters.

--- Part 7: Requirements for grounding resistance reduction materials. The purpose is to establish the requirements and tests for grounding resistance reduction materials in lightning protection systems method.

--- Part 8: Requirements for isolation components of lightning protection systems. The purpose is to establish the requirements for insulation supports and insulation down conductors and their special tight Requirements and test methods for firmware.

Lightning Protection System Components (LPSC) Part 6: Requirements for lightning strike counters (LSCs)

1 Scope

This document specifies the requirements for lightning strike counters and describes the corresponding test methods. Lightning strike counters are based on the lightning current flowing in the conductor.

To record the number of lightning strikes, this type of conductor is used to conduct only part of the lightning current, including some conductors of the lightning protection system (LPS), Conductors of surge protectors (SPDs) or other conductors.

LSCs used in hazardous environments must take additional requirements into consideration.

Note. In EU countries, see CLC/T S50703-2 for component test requirements for use in explosive environments.
