Overview
SIST 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
Applications
SIST 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.
