Explosive Atmosphere Testing
A product that is designed for or could potentially be placed in a hazardous, explosive environment must be evaluated, especially if it could cause the environment to ignite. This is imperative for products that operate within engine compartments, electrical panels that are mounted in adverse environments, pumps and much more. We can test using almost any mixture of propane or hexane gas and can support these tests with altitudes up to 50,000 ft. If you are concerned about your product’s potential risks, see us about putting your test plans in action.

Thermal Shock Testing
Thermal shock is a very important test for determining the reliability of a product when subjected to sudden changes in temperature and how this stress source can accumulate deterioration or physical damage in performance.

Salt Spray, Salt Fog & Cyclic Corrosion Testing
We service most industry segments with harsh environment, salt fog corrosion testing.If your product is coated or painted for the marine, automotive or military industries, we are equipped to provide accredited testing within multiple chambers.We provide ASTM sample preparation for coated and painted articles to ensure that your test is performed correctly.We also provide custom configurations with varied salt concentrations and temperatures for many customers with products that are used in unique environments. Products like circuit boards, electronic devices and sensors may all have specialized testing requirements.

Cyclic Durability (Fatigue) Testing
Today’s products are very complex and designed to minimize costs with the use of FEA software that can project fatigue hot spots. Using your analysis results, we can create a test plan that includes mechanical cyclic durability and environments that will best test your design.

Contaminating Fluid Testing
Products manufactured using plastics, coated and painted surfaces, seals or other "A" surface materials can come in contact with spilled chemicals, sweat, cleaners, lubricants and fuels that can be a potential stress source for a product. These stress sources can cause discoloration, deterioration and de-lamination failures. We can create a list of fluids and/or follow TRCA, DO-160, MIL-STD-810 and ASTM guidelines for a list of products that should be used to test your part's compatibility.

Pyroshock Testing
The purpose of Pyroshock (pyrotechnic shock) testing is to simulate the high-frequency, high-magnitude shock pulse experienced by an explosive event (such as an impact on a military tank or an explosive deployment charge). Pyroshock testing can expose failures in electronic components that are sensitive to high-frequency pyroshock energy. Common failures include: relay and crystal oscillator chatter, detachment of larger components from the circuit board, hard failures of small circuit components, and the dislodging of contaminants, which cause short circuits. Severe damage to crucial components used in space or in the military can produce critical results, such as loss of life, due to malfunction.

Connector Testing
If your product uses a connector or terminal, it can be susceptible to a unique set of failures that warrant specific connector testing conditions to determine the robustness of your design.

Acceleration (Centrifuge) Testing
Environment Associates provides centrifuge equipment for acceleration testing. Our acceleration testing equipment measures 3 ft. (0.91 m) and a 6 ft. (1.82 m) lengths that provides constant accelerations of 50 Gs and can handle payloads of 20 lbs. to 50 lbs. The Acceleration Testing is also called G-Force Testing

Tensile & Compression Testing
If you are looking for a value on the forces needed to assemble a product, or what it will take to overcome a connector latch or other device that mates together, let Environment Associates perform these tests for you. We can test in both tensile and compression on samples that are less than 14" (35.56 cm) wide and can handle product travel less than 54" (137.6 cm), with sensitivities at 0.01 lbs. (4.53 grams) at a wide range of speeds. EA specializes in the determination of connector performance for many different applications and styles.

Fungus Testing
Fungus can cause products to malfunction during operation and can grow on just about anything if the conditions are right. It will break down certain plastics, rubbers, paints and gaskets if it attaches itself and is left to grow. Fungus is known to short out electronic circuits.

901 Shock Testing
Environment Associates performs high-impact mechanical shock for all grades, classes and types of Navy ship board machinery, equipment, systems and structures. Our lightweight shock machine is approved by the Naval Surface Warfare Center for use in testing the survivability of Navy shipboard equipment to MIL-S-901D on items and fixturing weighing up to a combined 500 lbs.

Solar Radiation Testing
Solar radiation on materials can cause cosmetic deterioration with the fading or oxidation of plastic. This oxidation can make components start to fade and weaken. The heating effects of the sun can cause plastic, vinyl and/or metal components to shift or distort, causing operational interruption, shorts and false control inputs. The most significant effect is discoloration that cheapens the look of any quality product. These effects can be accentuated when combined with temperature and humidity.

Altitude Testing
Our environmental testing facilities simulate altitude testing from -400 ft. (-121 meters) to outer space at 100,000 ft. (30,480 meters) or up to 10-6 Torr (1.3e-7 kPa) with temperature applied as low as -300°F (180C). We can reach these heights within 5 minutes or less. We are capable to handle products measuring up to 4ft X 4ft X 8ft to many standards, including MIL-STD-810 and RTCA DO-160.
