Application of Leather Water Vapor Permeability Tester

Customer Background

A leading footwear and apparel testing laboratory provides quality assurance for leather and textile materials used in shoes and garments. The laboratory needed to accurately assess the breathability of materials worn next to human skin, ensuring that footwear and clothing maintain comfort by allowing sweat to evaporate efficiently.

Application Requirements

Material Breathability Testing: Measure the ability of leather and textiles to transmit water vapor over a specified time.

Standard Compliance: Must meet UNI EN IUP/15, UNI EN 13515, EN ISO 20344:6.6, BS 3144, DIN 53333, ISO 17699, and other relevant international and national standards.

Precise and Reproducible Measurement: Require accurate control of environmental conditions (20°C, 65% RH) and timing for reliable testing.

Multi-Sample Testing: Ability to test multiple samples simultaneously to improve efficiency.

Solution

The laboratory implemented the G185 Leather Water Vapor Permeability Tester, which offers the following key advantages:

Quantitative Measurement: Determines water vapor permeability by measuring the mass of water vapor transmitted per unit area and time.

Six Independent Test Stations: Each station includes a sample holder with silica gel desiccant; samples are fixed with a screw cap, enabling simultaneous testing of multiple specimens.

Rotating Worktable: Ensures even exposure of all test samples and facilitates consistent test conditions across stations.

Controlled Environmental Conditions: Test performed under specific temperature (20°C) and relative humidity (65%) for reliable results.

Integrated Timer and Control Panel: Allows for precise setting, monitoring, and recording of test duration.

Application Results

The laboratory achieved high repeatability in water vapor permeability measurements across multiple leather and textile samples.

Simultaneous testing of six samples significantly improved laboratory throughput and operational efficiency.

Provided reliable data to support footwear and apparel manufacturers in designing comfortable, breathable products.
