The Bundesmann Rain Tester simulates natural rainfall to evaluate the water repellency, wetting behavior, and absorption characteristics of textiles, including waterproof fabrics. The instrument features a rainfall unit with 300 uniform drips and a test-driving unit with rotating sample cups and cross-shaped wipers, ensuring precise and repeatable testing conditions.
Application
This tester is widely used for:
Measuring surface wetting, water absorption, and outflow of clothing and textile materials.
Testing waterproof fabrics for outdoor apparel, protective clothing, and technical textiles.
Supporting quality control, R&D, and process optimization in the textile and apparel industries.
Ensuring compliance with international water repellency and hydrostatic resistance standards.
Standards
JIS L 1092 – Test method for water resistance of textiles
GB/T 14577 – Bundesmann rain test method for fabric water repellency determination
ISO 9865 – Textiles: Determination of water repellency of fabrics using the Bundesmann rain test
BS EN 29865 – Textiles: Determination of water repellency of fabrics using the Bundesmann rain test
DIN 53888 – Textiles: Determination of water resistant permeability – Hydrostatic test
Features
(1) Rainfall portion consists of 300 identical drips for uniform precipitation.
(2) Test-driving portion has four sample cups with an outer diameter of 10 cm.
(3) Sample cups are mounted at 15° from vertical for realistic simulation.
(4) Each cup includes a sample installation box and cross-shaped wiper that gently rubs the fabric underside.
(5) Cups rotate around the instrument center, ensuring consistent exposure.
(6) Rainfall intensity is adjustable via a valve (100–300 ml/min per 100 cm²).
(7) Cross-wiper ensures uniform friction and contact pressure for accurate results.
