Описание (английский):

L'ISO 15148:2002 prescrit une méthode permettant de déterminer le coefficient d'absorption d'eau liquide à court terme, par immersion partielle sans gradient de température. Elle vise à évaluer la vitesse d'absorption d'eau par action capillaire lors de pluies continues ou battantes pendant le stockage sur chantier ou la construction sur des matériaux d'isolation ou autres qui sont normalement protégés. Cette méthode est applicable à des enduits ou revêtements qui sont soumis à essai avec le support sur lequel ils sont normalement appliqués. Elle n'est pas destinée à l'évaluation de l'absorption d'eau par des matériaux utilisés sous l'eau ou en contact avec des sols saturés, pour lesquels un essai par immersion totale est plus approprié.

Abstract

Overview

ISO 15148:2002 specifies a laboratory partial immersion test to determine the short‑term water absorption coefficient of building materials and products. The method quantifies capillary uptake (mass of water absorbed per unit face area per square root of time) and is intended to assess how materials behave when exposed to driving rain or surface wetting during storage and construction. It is not intended for materials used under sustained immersion or in saturated ground.

Keywords: ISO 15148:2002, water absorption coefficient, partial immersion, hygrothermal performance, capillary absorption.

Key topics and requirements

Principle: Measure mass gain of a specimen whose bottom face contacts water; remove surface water by blotting before each weighing. Results express absorption per unit area per √time.
Apparatus: Accurate balance (±0.1% of specimen mass), water tank with constant level control and point supports, and a timer.
Specimens:
- Representative, regular shape and thickness (preferably full product thickness).
- Water contact area ≥ 50 cm² (preferably ≥ 100 cm²); for materials with large particles, dimensions must exceed particle size requirements.
- At least 3 specimens; if individual face area
