Severe wind and rain conditions can be encountered anywhere in the world, often with little notice. Excessive wind can interfere with communications equipment, lead to premature wear and corrosion, and limit radar effectiveness. Properly testing your product or system components against wind and rain is necessary both for regulatory compliance and overall quality control.
At NTS, we have a long history of providing wind testing for civilian and military devices. We can design a testing program that lets you anticipate the effects of severe rain and winds, allowing you to make the necessary engineering changes to develop a better product overall.
Wind-driven rain testing assesses the effects of falling rainwater on various types of devices and enclosures. The wind and rain testing we perform here at NTS studies, among other factors, the effect of rain and subsequent moisture penetration on water resistant enclosures, water removal systems (drainage), radio communications, optical properties, radar effectiveness, weight increases and impeded functionality of mechanical devices, thermal exchange and propellant burn rates.
To simulate even the most severe wet weather conditions, NTS employs several types of wind propelled rain generators, the most powerful being a tandem fan fixture pushing rain at up to 90 mph. The same test equipment enables large coverage areas at lower speeds, easily covering a 15ft x 8ft (4.5m x 2.5m) area with 40 mph (64 kph) spray. NTS can throttle down the rain spray to any required velocity and volume you may require. Test items are either tested at their functional temperature or can be heated up to 50°F (10°C) higher than the water spray to further induce leakage.
Ultimately any system component, device or product that’s exposed to the elements needs to be properly tested for wind and water resistance. NTS can design a custom training program that takes all environmental factors into account and delivers useable findings that can help you further refine your products.
NTS maintains one of the largest nationwide networks of wind testing labs. We have the capabilities to precisely calibrate our tests to replicate diverse environmental conditions and identify with precision how these stresses affect your product.
