Scope
What IEC 62305-4 covers
Six interconnected measures — all required together. No single measure provides adequate protection in isolation.
Assess and reduce the electromagnetic threat from all four lightning source types — direct strikes, near-structure, and conducted surges on incoming service lines.
Certified air terminals, 25mm × 3mm copper tape, heavy-duty polymer earth chambers, bonding conductors, and test points — all traceable to the IEC 62561 series with full material certifications.
Full installation by trained technicians to MS IEC 62305 / JKR specifications. Works are documented throughout with photographic evidence and inspection hold points for consultant or authority review.
Continuity testing, earth resistance measurement, and full commissioning report per IEC 62305-3. Test certificates are issued in a format accepted for JKR, BOMBA, and consultant authority submission.
Scheduled post-installation inspections and maintenance to ensure ongoing compliance throughout the system lifecycle. Annual or biennial service programmes available per IEC 62305-3 inspection intervals.
As-built drawings, material traceability records, test certificates, and compliance documentation suitable for JKR, BOMBA, local authority, and international consultant review.
