Overview
ISO 16528-2:2007 - Boilers and pressure vessels - Part 2: Procedures for fulfilling the requirements of ISO 16528-1 - is a procedural ISO document that specifies a standard format and conformance procedure for standard-issuing bodies to demonstrate that their boiler and pressure vessel standards meet the performance requirements of ISO 16528-1:2007. It is intended to identify existing national or regional standards that adequately address the safety-related performance objectives set out in Part 1, and to provide a transparent, consistent way to document that conformance.
Key topics and requirements
ISO 16528-2:2007 focuses on process and documentation rather than prescriptive technical rules. Main elements include:
- Conformance procedure
- Steps for demonstrating that a standard satisfies the performance requirements of ISO 16528-1.
- Guidance on completing and publishing conformance information.
- Conformance tables (standard format)
- Table 1 - Failure mode summary: Identify which principal failure modes (e.g., brittle fracture, ductile failure, excessive deformation, buckling) are addressed (Y/N/P) and list any additional failure modes.
- Table 2 - Detailed failure mode checklist: For each failure mode, document explicit/implicit design rules, fabrication details, material requirements, examination and testing requirements, and use/application limits with clause references and explanatory comments.
- Table 3 - Detailed technical requirements checklist: Cross-reference how the standard covers ISO 16528-1 technical topics such as materials, design loadings, design methods and margins, examination and inspection, welding and heat treatment, testing, marking, and conformity assessment.
- Supporting process
- Use of a task force from ISO/TC 11 to assist standard-issuing bodies.
- Posting completed conformance tables on the ISO/TC 11 website (publication does not imply ISO adoption of the technical content).
Applications and users
ISO 16528-2:2007 is primarily useful for:
- National/regional standard bodies seeking to demonstrate that existing codes meet ISO performance requirements.
- Regulators and conformity assessment bodies evaluating equivalence between local standards and ISO performance objectives.
- Manufacturers, design engineers, and certification bodies who need to compare standards, document compliance paths, or justify use of non‑ISO codes.
- Technical committees and reviewers tasked with harmonizing boiler and pressure vessel safety requirements.
