In the EN 12524 standard, a European standard, design data are presented in tabular format for heat and moisture transfer calculations for thermally homogeneous materials and products widely used in building construction. In addition, this standard contains data that enables the calculation and conversion of design thermal values for various environmental conditions.
Furthermore, the International Organization for Standardization (ISO) has published ISO 10456 based on this standard (ISO 10456 Building materials and products - Hygrothermal properties - Tabular design values and procedures for determining declared and design thermal values). This ISO standard provides procedures for converting values obtained under one set of conditions to those applicable to another set of conditions and describes methods for determining declared and design thermal values for thermally homogeneous building materials and products. These procedures are valid for design ambient temperatures between -30 degrees and +60 degrees. ISO 10456 provides conversion coefficients for temperature and humidity. These coefficients are valid for average temperatures between 0 and 30 degrees. The standard also provides tabular design data for use in heat and moisture transfer calculations for thermally homogeneous materials and products commonly used in building construction.
The EN 12524 standard provides tools to partially assess the contribution of building products and services to energy savings and the overall energy performance of buildings. Heat and moisture transfer calculations require design values of thermal and moisture properties for materials used in building applications. Design values are derived from declared values, which are generally valid for thermal insulation materials and based on product-related measured data. Where the design conditions differ from the declared value, the data needs to be converted to valid conditions. This standard provides methods and data for doing this conversion.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services for hygrothermal properties and tabular design values of building materials and products, within the scope of EN 12524 standard, with its trained and expert staff and advanced technological equipment.
