Textile bondi door rain tester
The G816A Textile bondi door rain tester is designed to evaluate the water repellency of textiles under simulated rainfall conditions. The instrument measures the amount of water passing through the fabric and provides an objective assessment of fabric water repellency during dynamic conditions, such as exposure to rain while in motion.
Application
The tester is suitable for evaluating water repellency performance of various textiles, including:
Outdoor clothing fabrics
Sportswear textiles
Technical textiles for automotive or protective applications
Waterproof coatings on synthetic fabrics
Upholstery and canvas materials
Standards
The G816A Bondis Spray Tester complies with the following national and international standards:
(1) GB/T 14577-1993 – Test Method for Water Repellency of Textiles (China)
(2) ISO 9865 – Textiles – Water Repellency – Spray Test (International)
(3) BS EN 29865 – Textiles – Determination of Water Repellency – Spray Test (UK/Europe)
(4) DIN 53888 – Determination of Water Repellency of Fabrics (Germany)
(5) JIS L1092 – Test Methods for Water Repellency of Fabrics (Japan)

Test Procedures
Install the test specimen in the test cup at a 15° angle.
Adjust the leveling device to ensure the instrument is perfectly horizontal.
Set the desired spray volume (100–300 mL/min) and rotation speed.
Start the rotation of the test cup and cross scraper.
Activate the spray system; the water passes through the textile to measure repellency.
After the test duration, the instrument automatically stops and triggers an alert.
Record the water penetration results and assess fabric repellency according to the standard.
Maintenance Information
Clean the spray nozzles regularly to prevent clogging.
Wipe stainless steel surfaces with a soft cloth to prevent corrosion.
Check rotation motors and scraper mechanism for smooth operation monthly.
Ensure water supply is filtered and free of impurities.
Calibrate spray volume periodically to maintain test accuracy.
