ISO 15106-4:2008 specifies an instrumental method for determining the water vapour transmission rate of single-layer plastic film and sheet, as well as multi-layer structures including plastics, using a gas chromatograph. The method provides rapid measurement over a wide range of water vapour transmission rates.

Abstract

Overview

ISO 15106-4:2008 - Plastics - Film and sheeting - Determination of water vapour transmission rate - Part 4: Gas‑chromatographic detection sensor method - specifies an instrumental procedure for measuring the water vapour transmission rate (WVTR) of single‑layer plastic film, sheet and multi‑layer structures using a gas chromatograph. The method provides a rapid, sensitive measurement over a wide WVTR range and is intended for laboratory quality control, R&D and material comparison.

Key topics and technical requirements

Principle: A wet and a dry chamber are separated by the test specimen; permeating water vapour is collected in a sampling loop and quantified by gas chromatography.
Apparatus essentials:
- Transmission cell with wet and dry chambers; transmission area 0.5 cm² to 100 cm².
- Gas chromatograph capable of measuring water vapour with at least 0.05 µg accuracy.
- Gas flow controller (recommended 5–100 ml/min) and humidity controller (water reservoir).
- Vacuum pump capable of
