EN 1779:2026 – Non-Destructive Testing: Leak Testing – Criteria for Method and Technique Selection

Non-Destructive Testing – Leak Testing – Criteria for Method and Technique Selection

Released as a robust revision to the 1999 edition, EN 1779:2026 provides a comprehensive framework for selecting the most suitable leak test methods and techniques, focusing on gas leakage assessment for systems that can be either evacuated or pressurized.

Scope and Core Content

• Details criteria and procedures for assessing leak tightness by measuring or indicating gas leakage.
• Excludes hydrostatic and electromagnetic leak detection, focusing on gas phase methods.
• Includes a normative Annex A to compare standard test methods and guidance tables (e.g., test type, measurement vs. localization, test object design, functional/environmental requirements).
• Clarifies units and terminology in alignment with EN ISO 20484:2017, ensuring consistent application.

New in the 2026 Edition:

• Updated table and figures for method comparison and test selection
• Fresh section 8.1 providing enhanced principles for method and technique selection
• Revised normative references, ensuring latest global alignment

Who Should Use EN 1779:2026?

• NDT/NDE professionals in manufacturing, plant maintenance, and product verification
• Component and system designers requiring assurance of functional and environmental leak tightness
• Quality assurance and compliance managers responsible for critical containment or pressurized systems

Applied in fields such as process industries, energy utilities, pharmaceuticals, medical devices, and automotive systems, EN 1779:2026 ensures safety, regulatory compliance, and product reliability.

Key highlights:

• Systematic test method selection based on leakage rates, type of gas, geometry, operational risk, and safety/environmental concerns
• Identification and measurement of leaks in both local and total areas
• Consideration of pressure, temperature, flow regime, and corresponding test method factors

prEN ISO/ASTM 52969 – Additive Manufacturing of Metals: Non-Destructive Testing and Evaluation – Classification of Imperfections in DED Parts

Additive Manufacturing of Metals – Non-Destructive Testing and Evaluation – Classification of Imperfections in DED Parts (ISO/ASTM DIS 52969:2025)

Reflecting the rapid growth of additive manufacturing (AM) for metal parts, prEN ISO/ASTM 52969 brings new clarity to the classification of imperfections that can occur during Directed Energy Deposition (DED) processes. While it stops short of providing acceptance criteria, this standard defines and illustrates the main imperfection types and their typical causes—essential for both manufacturing process development and subsequent inspection.

What’s Covered?

• Systematic classification scheme for imperfections in DED-manufactured metal parts:
  • Crack types and formation origins
  • Porosity/cavity characteristics
  • Solid inclusion types
  • Lack of fusion (including cross-layer, vertical/horizontal, and operational influences)
  • Shape/dimensional imperfections
  • Other irregularities
• Links imperfection types to probable process causes and includes visual illustrations in Annex A.
• Adopts a numbering system for clear communication of defect types in industry documentation.

Industry Application

• Particularly valuable for AM part designers, NDT specialists, and quality personnel
• Facilitates clear communication between AM service bureaus, customers, and regulators
• Supports the implementation of robust inspection and quality monitoring regimes without dictating go/no-go criteria (since those depend on application-specific standards)

Key highlights:

• Endorsed by both ISO and ASTM, reflecting maximum international alignment
• Offers a tool for root-cause analysis and continuous improvement in metal additive manufacturing
• Covers DED variants: laser, electron beam, arc/wire (WAAM), including powder and wire feed processes

Industry Impact & Compliance

These standards collectively raise the bar for quality, risk mitigation, and global competitiveness in manufacturing and testing. Here’s what you need to know about compliance and transition:

• Mandatory or Voluntary? Depending on contractual obligations, regulatory demands, and industry sector, adherence may be required or strongly recommended.
• Transition Timelines: For revised standards, organizations should monitor transition periods or co-existence clauses as specified by industry or national regulatory bodies.
• Benefits of Early Adoption:
  • Reduces likelihood of test errors and ambiguous results
  • Enhances market access by ensuring alignment with presiding regulations and global buyers’ requirements
  • Strengthens internal quality management and continuous improvement
• Risks of Non-Compliance:
  • Potential for failed audits, rejected products, or unsafe equipment
  • Legal liability if products fail in service
  • Loss of certification or negative brand reputation

Action Points:

• Quality and compliance managers should promptly review how these standards interact with relevant design, testing, and inspection workflows.
• Ensure all relevant personnel are trained on new procedures and documentation practices.
• Update internal specifications to reflect terminology, reporting requirements, and selection criteria as outlined in each publication.

Technical Insights: Core Requirements and Implementation Best Practices

Common Threads Across the 2026 Testing Standards

• Clear Test Selection Guidance: All three standards emphasize the necessity to systematically select and justify appropriate test methods—including detailed tables, checklists, and cross-references to relevant terminology.
• Control of Environmental and Process Variables: From vibration frequency bands to gas selection in leak testing and machine setup in DED manufacturing, precise control and documentation are essential.
• Emphasis on Data Recording and Reporting: Each standard requires that specifications and test results be unambiguously recorded and reported to facilitate traceability, repeatability, and regulatory inspection.
• Competence of Personnel: Qualification of staff—either via internal assessment or certification to standards like EN ISO 9712:2022 (for NDT personnel)—is highlighted as a foundation for reliable results.

Implementation Best Practices

1. Gap Assessment: Benchmark current lab/test facility practices against the new requirements, identifying necessary updates in equipment, procedures, and documentation.
2. Documentation & Reporting: Adopt recommended tables and templates from each standard, especially for reporting test results, deviations, and severity levels.
3. Calibration & Metrological Control: Ensure all measurement systems are up-to-date with latest traceability and calibration protocols.
4. Cross-Disciplinary Collaboration: Especially for leak detection and AM imperfection classification, bring together design, production, maintenance, and quality teams for holistic review.
5. Industry-specific Customization: Tailor severity levels, acceptance criteria, and imperfection designations to your specific application and regulatory context.

Testing and Certification Considerations

• For vibration and environmental testing, consider third-party laboratory certification (such as ISO/IEC 17025 accreditation).
• For additive manufacturing and leak testing, participation in round-robin or proficiency testing can demonstrate compliance and build customer trust.
