EN ISO Standard 20345/347 says that boots must pass water penestation tolerance up to 3cm² to offically classify as water-resistant.
GORE-TEX® take their testing to the extreme, every new GORE-TEX® Footwear prototype is put through its paces in rigorous tests in the Gore testing labs. Not only is the GORE-TEX® Footwear style tested, but the entire system of outer material, insulation, membrane and lining has to prove its excellence under the toughest conditions. Only when a shoe fulfills the high quality and performance standards of GORE-TEX® products, is it cleared for production.
Their are three types are testing procedures for water testing; the Trough Test, Dynamic Test, and the GORE-TEX® standard tested Gore Walking Simulator
The GORE-TEX® testing procedures:
The GORE Walking Simulator
The Walking Simulator tests the waterproof performance of GORE-TEX® footwear. Test shoes are placed on flexible foot forms equipped with moisture sensors that are subject up to 200,000 steps in a water bath. If moisture enters the shoe, the testing stops and the sensor indicates the source of the leak. The shoe or boot must then be modified and submitted for another round of testing, to prove that they meet the rigorous GORE-TEX® footwear standards.
The Wicking Test
The GORE-TEX® lining isn’t the only component in footwear that ensures durable waterproofness. Materials used in the upper must also be non-wicking to prevent water from being transported into the shoe or boot over the GORE-TEX® lining. That’s why we test all upper components from the shoe’s leather and foam to the stitching and laces to ensure that the whole shoe or boot meets the waterproof performance standards.
The Centrifugal Tester
Boots filled with water are spun at high speeds. The resulting pressure forces water through even the smallest of holes to discover leaks. These tests are performed at every Gore certified factory.
The Comfort Test
Breathability is not only a feature of the GORE-TEX® membrane. All materials used, from the lining through to the outer material, contribute to the high breathability and climate comfort of GORE-TEX® Footwear. In the Comfort Test the entire shoe is tested for breathability which ensures that all components are working together to deliver climate comfort in the intended use.
GORE-TEX® protected boots are used where comfort is key. Look to GORE-TEX protected Work Boots for the protection and comfort level needed to not only protect your staff but to keep them comfortable. Many studies have been done that prove that if you are wearing the correct footwear not only do they keep you safe but also keep your feet dry and warm, then you are able to concentrate on the job you are doing more effectivity.
As a Groundsman working outdoors at all times of year and in all weathers is difficult enough, but to have to do it with cold, wet feet is just asking a bit too much. GORE-TEX® Protection means you no longer need to face this issue, and you can get on with the important stuff comfortably!
