SIST EN 1946-1:2000

Thermal performance of building products and components - Specific criteria for the assessment of laboratories measuring heat transfer properties - Part 1: Common criteria

This standard gives specific technical criteria to be used within the frame of the general criteria given in EN45001 and EN45002 for the assessment of laboratories performing heat transfer property measurements of building products and components according to standardized test methods. It is relevant both to assessments conducted internally and to those carried out formally by an accreditation body, and is intended to be of assistance to all interested parties.

Wärmetechnisches Verhalten von Bauprodukten und Bauteilen - Technische Kriterien zur Begutachtung von Laboratorien bei der Durchführung der Messungen von Wärmeübertragungseigenschaften - Teil 1: Allgemeingültige Regeln

Diese Europäische Norm legt die technischen Kriterien fest, die nach den allgemeingültigen Kriterien von EN 45001 und EN 45002 zur Begutachtung von Laboratorien bei der Durchführung der Messung von Wärmeübertragungseigenschaften von Bauprodukten und Bauteilen nach den Normprüfverfahren zu erfüllen sind. Sie gilt sowohl für die interne wie auch die grundsätzlich von einer Akkreditierungsstelle durchgeführte Begutachtung und ist als Hilfestellung für alle Beteiligten konzipiert.

Performance thermique des produits et composants pour le bâtiment - Criteres particuliers pour l'évaluation des laboratoires mesurant les propriétés de transmission thermique - Partie 1: Criteres communs

La présente norme donne les critères techniques particuliers à utiliser dans le cadre des critères généraux donnés dans l'EN 45001 et l'EN 45002 pour l'évaluation des laboratoires effectuant le mesurage des propriétés de transmission thermique de produits et composants pour le bâtiment selon des méthodes d'essai normalisées. Elle s'applique aussi bien aux évaluations menées en interne qu'à celles effectuées officiellement par un organisme d'accréditation. Elle est utilisable par toutes les parties concernées.

Overview

SIST EN 1946-1:2000 is a European standard developed by CEN that establishes specific technical criteria for the assessment of laboratories measuring the heat transfer properties of building products and components. This standard supplements the general laboratory assessment criteria outlined in EN 45001 and EN 45002, focusing specifically on thermal performance testing according to standardized methods. It applies to both internal laboratory assessments and formal evaluations by accreditation bodies. The standard aims to ensure reliable, accurate, and consistent measurement results in the building industry, promoting quality and confidence across laboratories involved in thermal insulation and related testing.

Key Topics

• Laboratory Assessment Criteria: Defines specific requirements for competency, equipment calibration, testing procedures, and quality control in laboratories measuring heat transfer properties.
• Thermal Performance Testing: Focuses on standardized test methods for evaluating the thermal insulation efficiency of building products and components.
• Compliance with EN 45001 and EN 45002: Enhances the existing general criteria with tailored technical provisions for heat transfer testing.
• Accreditation and Internal Audits: Provides guidance applicable to both formal accreditation processes and internal quality assurance systems.
• Common Criteria Framework: Part 1 of the EN 1946 series outlines general rules applicable across all relevant laboratories, serving as a foundation for more specific subsequent parts.

Applications

• Building Product Manufacturers: Ensures their laboratories meet established technical criteria to produce accurate thermal performance data.
• Testing Laboratories: Improves the quality and reliability of heat transfer measurements for building components such as insulation materials, walls, windows, and roofing products.
• Accreditation Bodies: Offers a standardized benchmark for evaluating laboratories specializing in thermal performance testing.
• Architects and Engineers: Gains confidence in thermal data sourced from compliant laboratories, supporting energy-efficient building design.
• Regulatory Compliance: Assists manufacturers and testing facilities in meeting mandatory building regulations related to energy efficiency and thermal insulation.

Related Standards

• EN 45001: General criteria for the operation of testing laboratories.
• EN 45002: Complementary rules to EN 45001 for specialized testing.
• EN ISO 6946: Building components and elements - Thermal resistance and heat transfer.
• EN ISO 9869: In-situ measurement of thermal resistance and thermal transmittance.
• ISO 8990: Determination of steady-state thermal transmission properties by means of guarded hot plate apparatus.

By aligning laboratory practices with SIST EN 1946-1:2000, the building industry achieves greater accuracy in thermal performance data, contributing to enhanced energy efficiency, sustainability, and compliance with international standards. This fosters trust among manufacturers, clients, and regulatory authorities, ultimately supporting the development of high-quality, thermally optimized building solutions.
