SIST EN 12667:2002

Overview

SIST EN 12667:2002 is a European standard published by CEN that specifies established principles and testing methods for determining the thermal resistance of building materials and products. The document details procedures for utilizing the guarded hot plate and heat flow meter methods to measure thermal resistance for products with a thermal resistance of at least 0.5 m²·K/W, covering both high and medium performance insulation materials. By standardizing testing approaches, this standard helps ensure reliability and comparability of thermal performance data throughout the construction sector.

Key Topics

• Thermal Resistance Measurement: Focuses on accurately determining the resistance of materials to heat flow, a key property for building insulation products.
• Test Methods:
  • Guarded Hot Plate Method: Recognized for its high accuracy, suitable for reference testing.
  • Heat Flow Meter Method: Widely used due to practicality and adaptability for various materials.
• Scope of Applicability:
  • Targets building products with thermal resistance ≥ 0.5 m²·K/W.
  • Applicable to insulation materials and other products where thermal resistance is critical.
• Reproducibility and Reliability: Emphasizes precise control of testing conditions to ensure consistent results across laboratories.

Applications

SIST EN 12667:2002 plays a crucial role in enhancing thermal insulation standards in the construction industry. Its applications include:

• Building Design and Certification: Supports architects, engineers, and contractors in selecting and verifying insulation materials to meet energy efficiency and thermal performance requirements.
