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.

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.

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.

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.

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.

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.

Temperature & Humidity Testing
Environment Associates is outfitted with multiple chambers to suit all types of temperature and humidity testing needs, including: table-top, standard-reaching, fixed or portable walk-in chambers, and if needed, drive-in chambers. All Environment Associates test chambers are equipped with separate data-acquisition equipment for temperature and humidity monitoring. Our temperature and humidity chambers can be readily equipped with specialized data acquisition to digitally record chamber conditions and the test article at multiple data points. Many of our temperature and humidity chambers are equipped with high-performance, maximum-size compressors to produce superior ramp rates equal to or greater than 15°C per minute.
