Temperature and Environmental Stress Testing

Temperature and Environmental Stress Testing

Temperature Testing

Determines how well equipment can operate in both high and low temperature environments. The testing can involve constant temperature exposure or cyclic temperature fluctuations to simulate real-world conditions.

Testing Categories

High-Temperature Testing

Evaluates how equipment performs in extreme heat conditions.

Low Temperature Testing

Assesses the performance of equipment in extremely cold environments.

Temperature Shock Testing

Tests the reaction of equipment to sudden changes in temperature, from hot to cold, or vice versa, in a short time frame.

Testing Capabilities

Dayton T. Brown, Inc. has over 30 chambers capable of simulating a wide range of high and low temperature and humidity conditions.

Chamber sizes range from 2.1 ft³ to 4,500 ft³, with relative humidity levels between 2% and 98%.

Our 25 ft. drive-in chamber (25 ft. x 15 ft. x 12 ft.) is equipped with over 240 HP of refrigeration, 240,000 KVA of heat, and a 42 KVA steam generator for humidity control.

Standard chambers simulate temperatures from -80°F to +325°F.

Enhanced facilities are available for testing at temperatures as low as -120°F.

Dual chambers for temperature shock testing to accommodate different sizes of test items.

ESS – Environmental Stress Screening

A critical testing process that’s designed to identify and eliminate manufacturing defects early by exposing products to accelerated environmental stresses. This ensures that only the highest-quality products are delivered to customers, reducing field failures and increasing reliability. By simulating real-world conditions, ESS improves product performance, durability, and compliance with regulatory standards.

Testing Categories

Temperature Cycling

Repeatedly exposes products to high and low temperatures to reveal potential failures caused by material expansion, contraction, or thermal stress.

Vibration Screening

Subjects items to mechanical vibrations to identify structural weaknesses and ensure durability during transport and operation.

Combined Environmental Testing

Integrates multiple stressors, such as vibration and temperature, to simulate the most challenging real-world conditions.

Testing Capabilities

Customizable testing profiles tailored to meet project-specific requirements.

Temperature cycling from -70°C to +150°C for rapid stress application.

Vibration frequencies from 5 Hz to 2,000 Hz for precise stress replication.

Combined environmental chambers for simultaneous temperature and vibration testing.

Quick-turn capabilities to meet tight deadlines and immediate testing availability.
