The Grey Zone of Plant Safety — FRALEX White Paper 2026

The Grey Zone of Plant Safety — Where Industrial Norms End | Free White Paper | FRALEX ESS

Free white paper by Frank Havemann, FRALEX ESS.

Where ASME, API, ISO and EN standards end — and what that means for live interventions on aged, pressurized systems in operation.

Every major industrial norm has a boundary. ASME B31.3 governs design. API 570 governs inspection. ASME PCC-2 governs repair. ISO 24817 governs composite repair. None of them govern the live intervention decision on a degraded, pressurized, operational asset at the moment the norm's own scope ends. This is the grey zone. This paper describes it — and how FRALEX ESS closes it.

For: Insurers | HSE Managers | Asset Integrity Managers | Maintenance Teams | Plant Engineers | Risk Assessors
