EN ISO 12628:2022/A1:2025 PDF

Overview

EN ISO 12628:2022/A1:2025 is an amendment to the European and international standard for thermal insulating products used in building equipment and industrial installations. Specifically, it addresses the methods for the determination of critical dimensional properties-dimensions, squareness, and linearity-of preformed pipe insulation. Developed collaboratively by CEN and ISO technical committees, this document standardizes the requirements for test reporting, ensuring uniformity in measurement and documentation processes across the insulation industry.

Maintaining precise geometric properties of preformed pipe insulation is essential to effective thermal performance, energy efficiency, and long-term durability in both residential and industrial settings. This amendment updates the test report content requirements to strengthen traceability and reproducibility in testing outcomes.

Key Topics

• Standardization of Dimensional Characterization

  • The amendment clarifies and supplements previous requirements for reporting the dimensions, squareness, and linearity of preformed pipe insulation.
  • Ensures the accurate and consistent assessment of insulation products for technical and regulatory compliance.

• Comprehensive Test Reporting

  • Specifies detailed information to be included in test reports, such as product identification, test procedure details, and individual measurement values.
  • Enhances transparency and accountability by enumerating attributes like product name, factory, manufacturer, production code, packaging, and test conditions.

• Enhanced Traceability

  • Mandates that information regarding sampling, specimen conditioning, process deviations, testing conditions (including tropical climates), and apparatus be systematically captured.
  • Provides for the recording of all individual measurement values and their means, facilitating effective quality control and product comparison.

Applications

EN ISO 12628:2022/A1:2025 is applicable to a wide array of industries and professionals involved with thermal insulation, including:

• Building Equipment and HVAC Ensuring that preformed pipe insulation for heating, ventilation, and air conditioning systems meets dimensional criteria for optimal performance.

• Industrial Installations Critical for process piping in facilities where energy conservation and plant reliability depend on high-quality, well-fitted insulation materials.

• Product Testing and Certification Laboratories, manufacturers, and certification bodies benefit from the revised reporting requirements, which support reliable compliance checks and product validation across different countries.

• Regulatory Compliance and Quality Assurance Explicit requirements for test documentation help satisfy regulatory mandates and streamline auditing processes for construction and industrial operations.

Related Standards

• EN ISO 12628:2022 The main standard for the determination of dimensions, squareness, and linearity of preformed pipe insulation, to which this amendment applies.

• ISO 163 Covers general thermal performance and energy use in buildings, under which ISO 12628 is categorized.

• Additional CEN/ISO Standards for Insulating Materials Many standards cover testing methods, handling, and application of thermal and acoustic insulating products in the construction and industrial sectors.

Practical Value

This amendment to EN ISO 12628:2022 ensures improved reliability in the assessment and reporting of dimensional properties for pipe insulation products. Compliance helps manufacturers, suppliers, and testing laboratories demonstrate product consistency, facilitating international trade and regulatory adherence. Standardized reporting improves communication among stakeholders, lowers the risk of installation errors, and underpins the performance and safety of thermal insulation systems in buildings and industrial facilities.

For organizations engaged in the development, testing, and installation of preformed pipe insulation, implementing the requirements outlined in EN ISO 12628:2022/A1:2025 fosters greater product credibility and market acceptance throughout Europe and globally.
