SIST EN ISO 29469:2023 PDF

Overview

EN ISO 29469:2022 - Thermal insulating products for building applications - Determination of compression behaviour (ISO 29469:2022) defines a standardized test method for measuring the compression behaviour of thermal insulation materials used in buildings. Endorsed by CEN and published November 2022, this standard supersedes EN 826:2013 and is intended for quality control, reference-value determination and use in short‑term loading and compressive creep test programs.

Key topics and technical requirements

• Scope and purpose: Specifies equipment, specimen preparation, conditioning and procedures to determine compressive responses of insulating products for building applications.
• Test principle: A compressive force is applied perpendicular to the major faces of a specimen at a controlled displacement rate; force and displacement are recorded to produce an F–X curve from which properties are calculated.
• Measured properties:
  • Compressive strength (maximum stress when failure occurs at
