Abstract

Overview

ISO 12572:2016/Amd 1:2024 is an important international standard that updates the methodology for assessing the hygrothermal performance of building materials and products. Specifically, it addresses the determination of water vapour transmission properties using the established . This amendment refines the procedures to enhance accuracy and consistency in measuring how building materials interact with moisture vapor under varying environmental conditions.

Key Topics

Water Vapour Resistance Factor (μ): The amendment revises subclause 8.6 to clearly define the calculation of the water vapour resistance factor, μ, which quantifies a material’s resistance to water vapour diffusion compared to air.
- μ is calculated using Formula (7), relating water vapour permeability of air and material.
- The Schirmer formula (Formula 8) is introduced to determine the water vapour permeability of air (δₐ) based on mean barometric pressure and temperature.
Influence of Barometric Pressure: The amendment highlights that both air and material vapour permeabilities vary with barometric pressure, but μ remains effectively independent of these changes when calculated correctly. Ensuring δₐ corresponds to actual barometric pressure is vital for accurate measurements.
Use of the Cup Method: The standard continues to promote the cup method-a widely accepted test technique where a material sample seals a container with controlled humidity conditions inside. Water vapour transmission rates are then measured, enabling assessment of material performance under realistic hygrothermal conditions.

Applications

ISO 12572:2016/Amd 1:2024 applies broadly in the building and construction industry to evaluate moisture-related properties of materials such as:

Insulation products
Vapor barriers and retarders
Wall and roofing assemblies
Facade materials
Flooring underlays

By providing reliable data on water vapour transmission, this test supports:

Building envelope design to prevent moisture accumulation and related damages like mold growth or structural deterioration
Improved energy efficiency by optimizing vapor control layers
Compliance with international building codes and green construction standards that demand rigorous moisture management
Material development and quality assurance for manufacturers aiming to meet performance benchmarks

Related Standards

ISO 13788: Hygrothermal performance of building components-internal surface temperature to avoid condensation and mould growth
ISO 8990: Thermal insulation-determination of steady-state thermal transmission properties-guarded hot plate apparatus
EN 12572: European equivalent standard describing the cup method for water vapour transmission
ISO/IEC Directives, Part 1 & 2: Governing protocols for developing and maintaining international standards

These complementary standards integrate with ISO 12572 to provide comprehensive guidance for assessing and mitigating hygrothermal risks in building envelopes.
