EN 12664:2001 - Overview
EN 12664:2001 (CEN) defines principles and testing procedures to determine the thermal resistance of building materials and products using the guarded hot plate and heat flow meter methods. The standard covers test specimens in the dry state or conditioned to equilibrium with moist air, targeting materials of medium and low thermal resistance. It applies to specimens with a thermal resistance of ≥ 0.1 m²·K/W and a (hygro)thermal transmissivity or thermal conductivity up to 2.0 W/(m·K). The document notes that many masonry specimens will usually have thermal resistance < 0.5 m²·K/W.
Key Topics and Requirements
- Measurement methods: Use of guarded hot plate and heat flow meter techniques to obtain reliable thermal resistance (R-value) data.
- Specimen conditions: Tests may be performed on dry specimens or those conditioned to moist-air equilibrium to reflect realistic hygrothermal behavior.
- Scope limits: Applies to products with R ≥ 0.1 m²·K/W and thermal conductivity ≤ 2.0 W/(m·K).
- Principles and procedures: Standard specifies fundamental measurement principles, required test arrangements, specimen handling and preparation, and how to determine thermal resistance from measured data.
- Reporting: Test results and conditions must be clearly documented to support product characterization and comparison.
Applications and Who Uses EN 12664
- Testing laboratories - perform standardized thermal resistance measurements for product certification and R-value verification.
- Material and insulation manufacturers - validate thermal performance of boards, mortars, plasters, masonry units and other building products in both dry and moisture-conditioned states.
- Product certification bodies and regulators - assess compliance with thermal performance requirements for building codes and labels.
- Building designers and energy modelers - use measured thermal resistance values to improve energy simulations and specify materials with reliable hygrothermal data.
- Research institutions - study material behavior under varying moisture conditions and compare measurement techniques (guarded hot plate vs. heat flow meter).
Related Standards and Notes
- EN 12664 is part of the family of CEN standards addressing thermal performance of building materials and complements other test methods for thermal conductivity and hygrothermal properties.
- When specifying tests or interpreting results, ensure the chosen method (guarded hot plate or heat flow meter) and specimen conditioning match the intended application (dry vs. moisture-equilibrated performance).
