T/SLPA 0004-2026 The specification for selecting the testing locations and quantities of lightning protection devices in explosive and fire-prone areas

Scope

1. Scope of Application Applicable to the detection of lightning protection devices in areas with explosion and fire hazards (such as gas stations, chemical plants, storage tank areas, etc.). 2. Requirements for Testing Agencies and Personnel The testing unit must have Class A lightning protection testing qualifications. The testing personnel must hold valid competency certificates. 3. Testing Frequency The first test should be completed before the thunderstorm season. Thereafter, at least one test should be conducted every 6 months. 4. Main Test Items Including: lightning arresters, down conductors, grounding devices, shielding measures, equipotential bonding, surge protectors (SPDs), etc. 5. Determining the Number of Tests All key items (such as material specifications, grounding resistance, etc.) should be tested. Other items should be sampled according to a certain proportion, generally 5% to 20%, with no less than 1 item. If there are fewer than 20 SPDs, all should be tested; if there are more than 20 SPDs, no less than 20% should be sampled. 6. What to Do if Problems Are Found If the sampled tests fail, the testing scope should be expanded; If the expanded tests still fail, all tests should be conducted and rectification measures should be implemented.
