ISO 24353:2008 specifies a test method for determining moisture adsorption/desorption properties of building materials in response to humidity variation. ISO 24353:2008 also defines the adsorption/desorption efficiency of building materials, measured as the change in mass of a specimen moved from a given space to another one of different relative humidity and equal temperature. Moisture adsorption/desorption properties of materials are measured under conditions of a single cycle and several cycles.
Abstract
Overview
ISO 24353:2008 - "Hygrothermal performance of building materials and products - Determination of moisture adsorption/desorption properties in response to humidity variation" - specifies a laboratory test method to quantify how building materials adsorb and desorb moisture when exposed to changes in relative humidity. The standard defines adsorption/desorption content, rates, and adsorption/desorption efficiency (mass change per unit surface area) for single-cycle and cyclic exposures. Test conditions, specimen preparation and measurement procedures are described to ensure repeatable hygrothermal performance data.
Key topics and technical requirements
- Scope: Measure moisture adsorption/desorption response of building materials to stepwise humidity changes; single-cycle and multi-cycle tests (including specific reference to fourth-cycle values).
- Specimens: Representative pieces, size 100 × 100 mm to 250 × 250 mm, thickness equal to the product; one specimen per test condition.
- Preconditioning: Bring specimen to constant mass (increase
