Temperature Testing Overview

Temperature testing, per MIL-STD 810 Methods 501, 502, and 503, tests an item’s ability to operate in extreme conditions. The testing can occur at a constant temperature exposure or a cyclic temperature exposure.

Constant Temperature Exposure

For constant temperature exposure, the test item is soaked until its temperature has stabilized and the test temperature is maintained for at least two hours following stabilization.

Cyclic Temperature Exposure

Cyclic temperature exposure has two procedures:

          Procedure I – Storage. MIL-STD 810 states that the number of cycles for the storage test is set at a minimum of seven. This is done to coincide with the one percent frequency of occurrence of the hours of extreme temperatures during the most severe month in an average year at the most severe location. (The maximum temperature occurs for approximately one hour in each cycle.)

When considering extended storage, critical materials, or materials determined to be very sensitive to high temperature, increase the number of cycles to assure the design requirements are met.

          Procedure II – Operation. MIL-STD 810 states that the minimum number of cycles for the operational exposure test is three. This number is normally sufficient for the test item to reach its maximum response temperature. A maximum of seven cycles is suggested when repeated temperature response is difficult to obtain.

Accelerated Aging

Accelerated aging testing is used to determine the expected life cycle of a product and can be beneficial in establishing storage period guidelines such as shelf life. One of the most common test procedures for accelerated aging is ASTM F1980, which focuses on sterile barrier systems for medical device packaging.

Through the use of heat, humidity, vibration, and other environmental variables, we can simulate the effects of conditions as they would impact a product or package long term. Temperature testing is a vital tool for accurate accelerated aging testing and our capabilities make us the right testing partner.

Temperature testing is just one of the climatics testing services we offer and our lab is fully equipped with the necessary equipment. Keystone Compliance is a temperature testing lab with significant experience with low-temperature testing and high-temperature testing. Contact us to discuss how we can help you meet your temperature test requirements.

Temperature Test Equipment and Capabilities at Keystone Compliance

Keystone Compliance offers temperature testing and temperature & humidity testing in chambers ranging from small benchtops to large drive-in systems. Our largest chamber has inside dimensions of 12’ wide x 10′ depth x 9’ tall. We have created custom oversized temperature chambers to accommodate much larger devices including cars, drones, and large pieces of machinery. If you have a large unit, we can likely find a way to test it.

Keystone Compliance is capable of moving, installing, and testing multiple rack assemblies. Our other large walk-in temperature test chamber is equipped with twin 30 hp compressors and is capable of temperature transition rates up to 20 degrees Celsius per minute. This chamber permits temperature cycling testing on large items with aggressive transition times.

We realize that temperature and temperature/humidity tests are the longest-running tests in your testing program and understand the importance of reliability and communication. Keystone testing engineers will ensure that your testing is done efficiently to produce the best result for you.

Keystone Compliance operates several different temperature and temperature/humidity test chambers. Chambers range in size from small benchtops to large drive-in systems. 

Temperature test capabilities in our reach-in and walk-in chambers range from low-temperature testing of -70°C to high-temperature testing of 200°C. We also have lab ovens that can reach up to 2,500°C. While these are standard temperature ranges, Keystone is capable of developing custom setups with a low temperature of -196°C. Between our wide variety of equipment and custom testing capabilities, Keystone can accomplish the temperature testing that you need.

Expert MIL-810 Regulatory Temperature Testing Lab

In addition to MIL-STD-810 temperature testing, Keystone has a full scope of expertise including sand and dust, solar radiation, rain, and pyroshock. Keystone has a full lab of test equipment which permits us to provide short lead times on scheduling. Our team strives to give our customers more time and energy on product development instead of testing.
