Understanding the Transition: EN ISO 24231 vs. EN 14360: What is the exact relationship between EN ISO 24231 and EN 14360? For textile testing laboratories and quality control centers, rest assured that these two standards share highly consistent core testing methods. In fact, the International Organization for Standardization (ISO) adopted the established EN 14360:2004 methodology and upgraded it into the globally applicable EN ISO 24231.

The original EN 14360:2004 specified a precise method for testing the rain resistance of garments by exposing a stationary mannequin to artificial rainfall, subjecting it to high-energy water droplets striking from above. Because the fundamental physics of the test remain unchanged, the proven mechanical design of the Wewon Environmental Chambers Co., Ltd. rain tower is already fully compliant with the new EN ISO 24231 requirements.

Our system’s precise construction-featuring a circular drip tray with a diameter of at least 1000mm and exactly 682 high-precision nozzles-perfectly satisfies the rigorous structural and performance parameters mandated by both the legacy and the latest international standards. Of course, we will also prepare the manikin mentioned in the testing standards and deliver it to you along with the rest. We provide you with a one-stop service!

Rain Tower Test System (EN 14360) Garments Waterproofness Test System

●	The test sample is positioned on the manikin and the water supply is started. It shall be waited until the tub is filled, i.e. until the overflow pipe is active.	Test Procedure
●	Then allow raindrops to fall down on to manikin. If not specified, the test duration shall be 1 h. Of course, The time when the raindrops fall on the mannequin can be negotiated with the customer. Some customers have stricter requirements on clothing fabrics, and the time for raindrops to fall will be relatively extended to 2 hours or longer.
●	After the test duration time, allow the test garment to drain for 2 min. Remove the test garment carefully avoiding drops contacting the underwear. This requirement and steps are very clearly specified and explained in the EN 14360 test standard. In order to ensure the authenticity of the test data, please respect the execution !
●	Examine the inner face of the test garment. Measure the surface of all wetted areas on the underwear and determine the total wetted area in cm.
●	A minimum of two separate specimens per type of garment shall be tested. If one specimen fails, then a third specimen shall be tested. Therefore, it is a wise choice to provide 4 or 5 independent samples to the testing center. EN 14360 specifies a minimum of 2 samples for successful testing.
●	If only one test garment is available, the same test garment shall be tested twice. The test garment shall be dried and conditioned as indicated above before the next test starts.
●	The product standard may specify a greater number of tests. A repetition rain test of the same specimen can influence the test results.
●	Normally the second test of the same specimen shows a greater water ingress due to the worse repellency. This is an indisputable fact. Therefore, the data of the first test and the second test are different, we must admit and accept and understand the actual situation.︱Rain Tower Test System (EN 14360) Garments Waterproofness Test

rain tower system with motion-manikin according to ISO 6956 standard

As the global testing landscape evolves, our cutting-edge Rain Tower Test System provides a comprehensive solution for evaluating the waterproofness of protective clothing and outdoor garments.	Advanced Rain Tower Test System: Fully Compliant with ISO 6956, EN ISO 24231, and EN 14360
While the EN ISO 24231 and EN 14360 standards have long relied on exposing a static manikin to artificial rainfall, the newly introduced ISO 6956 standard revolutionizes testing by utilizing a motion-manikin.
This dynamic approach simulates the physiological marching movements of an adult in a real-world rainfall environment.
Our meticulously engineered rain tower system is fully compatible with this transition, seamlessly accommodating both static and motion-manikin configurations to meet the exact testing requirements of advanced textile laboratories.
A defining feature of the ISO 6956 standard is its demand for variable rainfall simulations. Our upgraded rain tower test system not only meets the traditional high-energy droplet requirement of (450±50)l/m2h specified in EN 14360, but is also precisely engineered to control water levels to accurately simulate (150±50)l/m2}h light rain environments.	ISO 6956: Precision Simulation for Light and Heavy Rain Conditions
The robust mechanical structure features a circular tub with a diameter of at least 1000mm, positioned at least 5000mm above the floor.
Equipped with exactly 682 high-precision nozzles with a 0.6mm hole diameter, the system ensures uniform droplet distribution and terminal velocity.
Whether you are testing high-performance outdoor apparel or heavy-duty personal protective equipment, our system guarantees strict compliance with the precipitation parameters of ISO 6956 and EN ISO 24231.
To overcome the limitations of subjective visual inspections, ISO 6956 introduces a digital area measurement system for analyzing the wetted areas on the absorbent underwear.	Next-Generation Digital Measurement and Turnkey Solutions: ISO 6956
We deliver a complete testing solution that includes the industry-standard motion-manikin, a controlled D65 standard lighting booth, and digital image analysis compatibility to calculate accurate wet ratios.
By integrating these advanced capabilities, our ISO 6956 Rain Tower Test System empowers quality control centers to obtain highly reliable, numerical water penetration data.

To facilitate extensive data analysis, the system integrates a range of high-precision sensors, including dynamic flow meters and multi-point moisture sensors, which feed real-time data back to our centralized control software. This allows for unparalleled precision in recreating any desired environmental profile and ensuring repeatable, traceable testing across global standard compliance requirements.

Our advanced software offers user-friendly graphical interfaces for easy configuration, real-time visualization of all parameters, and comprehensive automated reporting. Integrated safety protocols ensure operator well-being, including emergency stop and automated leak detection. To support your long-term success, we offer comprehensive training, regular system calibration services, and ongoing technical support for optimized performance.

Whether your laboratory requires the standard 450 l/m²h cloudburst condition mandated by EN ISO 24231 and EN 14360, or needs to seamlessly transition to the variable 150 l/m²h light rain settings introduced by ISO 6956, this intelligent water supply system ensures precise, stable, and repeatable testing environments for premium protective clothing.

The rain test system with multi-stage filtration and automated pressure regulation, it guarantees that water purity and flow rates remain consistent throughout the evaluation process. The integrated diagnostic sensors actively monitor system health, providing preventative alerts to operators and ensuring minimal downtime while maximizing the lifespan of all critical liquid & pipes components. This is what makes the equipment stand out.

Exposing protective garments to extreme vertical and storm-driven rain conditions is essential for verifying true waterproof performance. In this rigorous evaluation process, specialized manikins equipped with moisture sensors at critical points are subjected to intense cloudburst simulations of over seven times the intensity of a natural downpour.

Our equipment accommodates both the static manikin testing required by EN ISO 24231 and the innovative motion-manikin dynamic testing specified by ISO 6956. By employing proven pass/fail criteria and supporting advanced digital area measurement systems, we provide European and North American testing centers with unimpeachable, quantitative data on garment water resistance.
