Full title and description

ISO 10456:2007 — Building materials and products — Hygrothermal properties — Tabulated design values and procedures for determining declared and design thermal values. This International Standard gives tabulated design data and procedures for determining declared and design thermal values and for converting values between different temperature and moisture conditions for thermally homogeneous building materials and products.

Abstract

ISO 10456:2007 specifies methods for the determination of declared and design thermal values for thermally homogeneous building materials and products, together with procedures to convert values obtained under one set of conditions to those valid for another set of conditions (valid for design ambient temperatures between −30 °C and +60 °C). The standard provides conversion coefficients for temperature and moisture (valid for mean temperatures between 0 °C and 30 °C) and tabulated design data for use in heat and moisture transfer calculations.

Scope

ISO 10456:2007 applies to thermally homogeneous building materials and products and provides tabulated design thermal values and conversion procedures so that thermal resistance, thermal conductivity and thermal transmittance data can be declared or converted consistently for use in heat- and moisture-transfer calculations. The procedures cover design ambient temperatures in the range −30 °C to +60 °C and include temperature- and moisture-related conversion coefficients for mean temperatures between 0 °C and 30 °C.

Key topics and requirements

• Tabulated design thermal values for common thermally homogeneous building materials and products.
• Procedures to determine declared and design thermal values for materials and products.
• Conversion coefficients for temperature and moisture to adjust measured or declared values between different conditions (mean temperatures 0–30 °C).
• Applicability limits and instructions for use in heat and moisture transfer calculations (design ambient temperatures −30 °C to +60 °C).
• Compatibility with related EN/ISO documents and national implementations; corrigendum issued in 2009 to amend specific table entries.

Typical use and users

Engineers, architects, building physicists, product manufacturers, test laboratories and regulatory authorities use ISO 10456:2007 to obtain consistent design thermal values for building materials and products, to convert laboratory values to design conditions, and to support thermal calculations for compliance, energy modelling and hygrothermal assessments.

Related standards

Standards commonly used alongside ISO 10456 include EN/ISO and national standards on thermal resistance and transmittance (for example EN ISO 6946 / ISO 6946), standards for laboratory determination of thermal resistance (EN 12667, EN 12664), water vapour transmission (ISO 12572) and standards on calculation of U‑values for glazing (ISO 10292). Many national adoptions appear as BS EN ISO 10456:2007 and equivalent EN ISO publications.

FAQ

Q: What is this standard?

A: ISO 10456:2007 is an International Standard that provides tabulated design thermal values and procedures for determining and converting declared and design thermal values of thermally homogeneous building materials and products.

Q: What does it cover?

A: It covers methods and tabulated data for thermal properties (resistance, conductivity, transmittance), conversion procedures for temperature and moisture effects, and limits of applicability for design ambient temperatures from −30 °C to +60 °C.

Q: Who typically uses it?

A: Architects, building physicists, energy modellers, product manufacturers, testing laboratories and regulatory bodies use the standard when selecting, declaring or converting thermal values for building materials and when performing hygrothermal and energy calculations.

Q: Is it current or superseded?

A: The 2007 edition (Edition 3) is the published edition; a technical corrigendum (ISO 10456:2007/Cor 1:2009) was published in December 2009. ISO lists the 2007 edition as the current published edition while a revision project (ISO/AWI 10456) is recorded in the ISO work programme. Users should check the ISO catalogue or national standards body for the latest status before use.

Q: Is it part of a series?

A: ISO 10456 is part of the family of ISO and EN documents addressing hygrothermal performance, thermal insulation and thermal transmittance of building components (it is often published/adopted as BS EN ISO 10456:2007 in national catalogues and cross-referenced with related EN/ISO thermal performance standards).

Q: What are the key keywords?

A: Hygrothermal properties, thermal resistance, thermal transmittance, design values, declared values, conversion coefficients, building materials, heat transfer, moisture transfer.
