Water and Climate Exposure Testing

Water and Climate Exposure Testing

Immersion Testing

Immersion Testing evaluates a product’s ability to perform as designed after being partially or fully submerged in water. This critical testing simulates real-world conditions to ensure the reliability of equipment exposed to wet environments, including underwater operations or accidental submersion. Products are typically secured to a heavy plate and immersed to the required depth, providing essential insights into their durability and performance.

Testing Categories

Standard Immersion

Testing standard and oversized equipment by partially or fully submerging in water.

Deep Pressurized Immersion

Simulating deeper immersion depths by pressurizing the tank environment to replicate various submersion conditions.

Specialized Immersion Testing for Hybrid and Electric Vehicles

Focused testing for hybrid and electric vehicles to verify the operation of onboard systems in conductive seawater environments.

Wind and Rain Testing

Wind and Rain Testing evaluates the ability of equipment and materials to withstand environmental exposure to wind and rain, ensuring the effectiveness of protective covers, seals, and water removal systems. This testing helps identify potential vulnerabilities like water penetration and material degradation in various weather conditions.

Testing Categories

Rain and Blowing Rain Testing

Tests the effectiveness of protective covers, seals, and cases in preventing water penetration under varying rainfall and wind conditions.

Exaggerated Rain Testing

Evaluates the sealing capabilities of enclosures under high-velocity rain conditions.

Drip Testing

Simulates condensation or leaks from an above surface area, assessing functionality and integrity under these conditions.

Testing Capabilities

Simulate up to 4 in. of rain with winds up to 40 MPH, with variable rainfall rates ranging from 1 in./hr. to 6 in./hr.

Accommodate items up to 12 ft. x 12 ft. x 10 ft. for high-velocity rain testing to evaluate sealing capabilities.

Simulate condensation or leaks from an above surface area with drip rates up to 11.25 in./hr., tested over an 8 ft. x 8 ft. area.

Ice/Freezing Rain Testing

Ice/Freezing Rain Testing evaluates a product’s performance under icy conditions, ensuring it operates reliably despite environmental challenges. This testing identifies potential issues such as the binding of moving parts, reduced airflow efficiency in cooling systems, or diminished aerodynamic performance. By simulating rapidly changing temperatures, altitudes, and humidity levels, this testing ensures your product meets real-world demands.

Testing Categories

Direct Ice Testing

Simulates the effects of freezing rain and ice accumulation on test items, ensuring their performance under conditions where ice may form on external surfaces.

Internal Ice Testing

Focuses on evaluating how equipment performs when exposed to internal freezing, simulating conditions where humidity is absorbed and rapidly frozen within the item.

Testing Capabilities

Walk-in chambers create ice accumulation on the test item.

Ice thicknesses range from 1/8 in. to 4 in., accommodating various industry requirements.

Temperature/altitude/humidity chambers can simulate cyclic actions, causing test items to "breathe in" humid air before rapidly lowering the temperature to induce internal freezing.
