General Information
Overview
EN 1946-2:1999 (CEN) defines specific technical criteria for the assessment of laboratories performing steady-state heat transfer property measurements of building products by the guarded hot plate method. This Part 2 standard complements the common assessment criteria in Part 1 and gives concrete guidance on how laboratories should organize documentation, calibrate equipment, maintain apparatus, and document measurement procedures when testing thermal performance and thermal insulation properties of building components.
Key Topics and Requirements
- Scope of measurement method: Focus on the guarded hot plate method for steady-state determination of heat transfer properties of building products and components.
- Laboratory assessment criteria: Specific technical requirements that laboratories must meet to ensure reliable, reproducible results when using the guarded hot plate technique.
- Documentation and manuals: Guidance on the content and organization of the equipment manual - including descriptions of guarded hot plate apparatus, accessories and operational limits.
- Calibration and maintenance: Requirements for calibration files and maintenance records to demonstrate traceability and ongoing performance of sensors, plates and control systems.
- Measurement procedures: Expectations for the measurement procedure document, detailing steady-state test setup, environmental control, data acquisition and uncertainty considerations.
- Complementary criteria: How Part 2 complements the common laboratory criteria in EN 1946‑1, addressing method-specific issues for the guarded hot plate.
Applications and Users
EN 1946-2:1999 is targeted at organizations and professionals involved in thermal testing and certification of building materials:
- Testing and calibration laboratories seeking assessment, accreditation, or to demonstrate competence in guarded hot plate measurements.
- Manufacturers of thermal and sound insulating materials and building components who require validated thermal conductivity or resistance data for product development and declarations.
- Certification bodies and notified bodies assessing laboratory capabilities and conformity of thermal performance data.
- Researchers and consultants working on thermal performance, building physics, and energy efficiency analyses.
Practical benefits include improved measurement reliability, transparent documentation for audits, and better comparability of thermal property data across labs.
