Описание (английский):

This document specifies two alternative methods for determining hygroscopic sorption properties of porous building materials and products: a) using desiccators and weighing cups (desiccator method); b) using a climatic chamber (climatic chamber method). The desiccator method is the reference method. This document does not specify the method for sampling. The methods specified in this document can be used to determine the moisture content of a sample in equilibrium with air at a specific temperature and humidity.

Overview

EN ISO 12571:2021 - Hygrothermal performance of building materials and products: Determination of hygroscopic sorption properties (ISO 12571:2021) defines standardized laboratory procedures to measure how porous building materials absorb and desorb moisture from air. The document specifies two alternative test routes - the desiccator method (reference method) and the climatic chamber method - to determine the equilibrium moisture content of a sample at a given temperature and relative humidity. The standard does not cover sampling methods; it focuses on test apparatus, procedures, calculations and reporting.

Key topics and requirements

Test methods

Desiccator method: uses desiccators and weighing cups; treated as the reference technique.
Climatic chamber method: uses controlled-environment chambers to establish humidity and temperature points.

Objective: determine hygroscopic sorption properties (sorption and desorption curves) and equilibrium moisture content at specified temperature and relative humidity.

Apparatus and specimen: requirements for desiccators, weighing equipment, climatic chambers and test specimen specification (number and preparation).

Procedure: stepwise instructions for establishing sorption and desorption curves, control of environmental conditions, and criteria for equilibrium.

Calculation and reporting: how to calculate moisture content (mass/volume bases), express sorption curves, and prepare a compliant test report.

Accuracy and control: guidance on measurement error, control of humidity/temperature, and verification of test environment.

Informative annexes: practical guidance on relative humidities above saturated solutions, preparation of saturated solutions, example procedures, and alternate methods (e.g., glass jar technique).

Applications

Determining equilibrium moisture content and sorption isotherms for porous building materials (e.g., masonry, insulation, wood-based products, plasters).

Supplying validated input data for hygrothermal simulation and moisture transport models used in building physics and durability assessments.

Supporting product development, quality control and performance claims related to moisture buffering, mould risk, and long-term durability.

Informing specification and selection of materials in damp-prone environments and aiding compliance with building regulations and performance standards.

Who uses this standard

Laboratory technicians and accredited test labs performing hygroscopic measurements.

Manufacturers of building materials and components for product characterization and quality assurance.

Building physicists, hygrothermal modelers and researchers using sorption data for simulations.

Specifiers, architects and consultants assessing moisture-related performance and material suitability.
