Breathable Standards Breathable Standards When industrial workers must perform their job in foul weather, it certainly makes the job more difficult. Why then should that worker be uncomfortable as well? Traditional liquid-proof products not only keep liquid out but also keep the heat that your body produces while working contained inside the suit. The build up of heat then condenses and soaks back into your clothing where you end up soaking wet and uncomfortable. Today, the breathable technologies that previously existed only in the recreation market now can be applied to products that are designed to protect against industrial hazards. This means that not only can you be safe but comfortable at the same time. Breathability can be measured several ways. ASTM E96 measures the amount of moisture vapor that transmits through a material (MVTR). ASTM F1868 measures the ability of a material to release heat as it is built up, or Total Heat Loss (THL). Regardless of the method, the result yields a product that increases worker comfort without compromising safety. Resource Info Breathable vs. Non-Breathable Raingear P.O.
