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.

Life Cyclic Durability Testing
-
Environment Associates can provide everything you need for cyclic durability testing and performance fixturing. Services include mechanical cycling to a position or load, fatigue cycling to a fixed load, rotational torque cycling, and simple push/pull cycling. EA can design your fixture with electro-dynamic, air, or hydraulic assistance to mechanically move your part. All of our fixtures can be manufactured to withstand a wide range of temperature, humidity and vibration inputs. If required, forces can be monitored electronically, using a wide variety of inputs (i.e. strain gages, load cells, rotational transducers, thermocouples, shunts, and more). EA can create holding and check fixtures to perform “pre” and “post” evaluation for dimensional issues that may occur during testing. EA can provide fixtures for single tests run internally for EA test labs and can manufacture fixtures to be purchased directly by the customer for their internal use.

Wind & Rain Testing
-
Using an adjustable aircraft prop coupled to a high-powered engine provides the ability to perform wind and rain testing to MIL-STD-810, RTCA DO-160 as well as other environmental testing requirements.

Vibration Testing
-
As specialists in dynamic testing, we provide equipment capable of exerting a 6,000 to 40,000 pound force with the capacity to perform closed-loop control from a single input to multiple channel inputs (from 2 to 32) with averaging or notched channel control. Vibration control systems can be programmed for real time monitoring, scheduled for length of time, or level scaled by dB or percentage, or scaled at various durations at different acceleration levels.

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.

Product
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.

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.

Product
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.

Shock Impact Testing
-
Environment Associates provides everything you need in drop shock testing — package/container, drop shock/impact systems and electro-dynamic simulated pulses. With our equipment, we specialize in tuned, matched impacts from 20 Gs to 30,000 Gs and from 30 ms to .02 ms in sine, saw-tooth, square-wave, gunfire and rotational cam pulses for almost any set of standards, or for any real-life condition. We can also handle a large range of weights and sizes. EA’s specialists will match the right test, equipment and configurations to your product. We also provide fixture design and special set-up solutions to mount and monitor your product’s functionality during and after testing.

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.

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 Vacuum Testing
-
When you want to test your product for extreme space conditions, that include temperatures from 155°C to -175°C at space vacuum altitudes, Environment Associates is your solution. Using this test to determine the unique failures of space mechanisms that orbit the earth is key in improving system reliability. Thermal vacuum testing is similar to thermal cycling but adds deep space vacuums for detecting corona/arcing and intermittence and increases a product’s out-gassing. The key failure modes found during this test are: 1) electrical iIntermittence, 2) thermal control issues, 3) arcing, 4) corona, 5) material out-gassing, and more, to determine a product’s flight-worthiness for workmanship and processing issues.

Accelerated Aging Testing
-
Accelerated aging is a testing method used to estimate the useful lifespan of a product when actual lifespan data is unavailable. This occurs with products that have not existed long enough to have gone through their useful lifespan: for example, a new type of car engine or a new polymer for replacement joints or medical products and packaging.
