Full title and description

STB BS EN 13445-5:2021+A1:2024 — Unfired pressure vessels — Part 5: Inspection and testing. Consolidated edition of EN 13445-5:2021 incorporating Amendment A1 (2024). Specifies inspection, non‑destructive and destructive testing, proof testing, acceptance criteria, marking and documentation requirements for single and serially produced steel unfired pressure vessels, with additional annexes for cyclic operation and creep-range service.

Abstract

This Part sets out the inspection and testing requirements that apply to pressure vessels manufactured to EN 13445‑2:2021. It covers the performance of inspections during fabrication, requirements for NDT and destructive testing, proof testing and calibration, the content of technical documentation and final assessment/marking. Informative and normative annexes include special provisions for cyclic service (Annex G) and for vessels or vessel parts operating in the creep range (Annex F and Annex I). Responsibilities in relation to conformity assessment follow Directive 2014/68/EU (PED) with guidance referenced in CR 13445‑7.

Scope

This Part specifies inspection and testing for individual and serially produced pressure vessels made of steels in accordance with EN 13445‑2:2021. It applies to fabrication inspection, acceptance criteria, routine and special tests, non‑destructive examination methods and qualification of testing personnel where referenced, proof testing and marking. Special provisions are included for cyclic operation and for components expected to operate in the creep range. The document is intended to be used alongside other parts of the EN 13445 series and in the context of the Pressure Equipment Directive (2014/68/EU) for conformity assessment.

Key topics and requirements

• Inspection programme during fabrication: stages, responsibilities and records.
• Non‑destructive testing (NDT): methods, acceptance criteria, sampling, and required qualifications for NDT personnel.
• Destructive testing and material verification: sampling, mechanical tests and metallographic checks where required.
• Proof testing and leak testing: procedures, pressures and acceptance limits.
• Technical documentation: required content for drawings, calculations, test reports and traceability records.
• Marking, final assessment and documentation to demonstrate conformity with the standard and applicable legislation.
• Special annexes: provisions for cyclic service (Annex G) and for creep‑range service (Annex F and Annex I).
• References and interfaces with other standards and regulations (e.g., EN 13445‑2, EN 13445‑4, EN ISO 9712 and Directive 2014/68/EU / CR 13445‑7 guidance).

Typical use and users

Used by pressure‑vessel designers, fabricators and manufacturers, quality and inspection engineers, NDT service providers, notified bodies and conformity assessment authorities, plant owners and operators, and procurement/specification teams. Typical applications include petrochemical, power generation, process industries and any facility manufacturing or placing unfired pressure vessels on the market within jurisdictions that adopt EN standards.
