Indirect lightning simulates secondary currents and voltages that travel through circuitry and cabling. The testing is also referred to as a surge immunity test.

  • Ingress Protection – Dripping Water Tests (IPX1 and IPX2)

    Keystone Compliance

    Ingress protection testing tests the level of protection an enclosure provides against intrusions. One such set of ingress protection tests is called the dripping water test. These tests are numbered IPX1 or IPX2. The first digit, represented by the “X”, ranges from 0 to 6 and specifies the protection from solid particles. The second digit, in the case of the dripping water ingress protection test, would always be either a 1 or a 2.

Two such sets of ingress protection tests involve exposing the equipment under test (EUT), to spraying water and splashing water. These tests are numbered IPX3 and IPX4. The first digit, represented by the “X”, ranges from 0 to 6 and specifies the protection from solid particles. The second digit, in the case of spraying water, would always be a 3, and in the case of splashing water, would always be a 4.

  • Ingress Protection: Water Jets and Powerful Water Jets Tests (IPX5 & IPX6)

    Keystone Compliance

    Ingress protection testing tests the level of protection an enclosure provides against intrusions. Two such sets of ingress protection tests involve exposing the equipment under test (EUT), to water jets and powerful water jets. These tests are numbered IPX5 and IPX6. The first digit, represented by the “X”, ranges from 0 to 6 and specifies the protection from solid particles. The second digit, in the case of water jets, would always be a 5, and in the case of powerful water jets, would always be a 6.

  • Humidity Testing

    Keystone Compliance

    Keystone Compliance offers temperature and temperature humidity testing in chambers ranging from small bench top to large drive-in systems. Our largest chamber was specifically oversized in design. With inside dimensions of 12’ wide x 15’ long x 10’ tall and an 8’ x 9’ door, Keystone Compliance is capable of moving, installing, and testing multiple rack assemblies. Keystone Compliance also operates a large walk-in chamber that is specially equipped with twin 30 hp compressors and is capable of temperature transition rates exceeding 15 degrees Celsius per minute.

  • Immersion Testing

    Keystone Compliance

    Keystone Compliance offers immersion testing to depths exceeding 100 feet. Immersion test setups are often unique to the test article and require the use of specialized pressure vessels. With multiple pressure vessels available, Keystone Compliance is able to offer immersion testing of various-sized test articles to almost any depth. Keystone Compliance operates various pressure vessels and associated support equipment. Keystone equipment is capable of simulating depths beyond 100 feet. One of the immersion test tanks measures 16 feet tall and has a radius of three feet.

  • Altitude Testing

    Keystone Compliance

    Altitude testing, also referred to as low pressure testing, per MIL-STD 810 Method 502.4, is performed to ensure that equipment can withstand and operate in a low pressure test or high altitude test environment. Altitude testing is intended to be used for air shipment of material in a plane, equipment designed for installation at high ground elevations and explosive decompression due to aircraft damage. Manufacturers of any device that is transported by air should consider the impact high altitude testing or low-pressure testing could have on their products. A low pressure test can simulate the problems high altitude can create such as:

  • Reliability Testing

    Keystone Compliance

    The reliability test program includes a number of qualification tests based on the type of product, the environment within which it is anticipated to operate in and estimated product weaknesses. Establishing an effective but practical and affordable test program can be a challenge. Reducing the number of units tested or the scope of testing might not yield a sufficient sample of results. Testing multiple units or having an expansive test program can be very time consuming and expensive. A very good resource for establishing a reliability test program is MIL-HDBK-781: Handbook for Reliability Test Methods, Plans and Environments for Engineering, Development, Qualification and Production. This handbook provides test methods, test plans and test environmental profiles which can be used in reliability testing during the development, qualification, and production of systems and equipment.

  • Salt-Fog Testing

    Keystone Compliance

    Keystone Compliance has a salt fog chamber that is one of the largest salt fog chambers manufactured and has an inside dimension of 8’ x 4’ x 4’. However, we have created custom oversized 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. The chamber is capable of salt fog testing, salt mist testing, salt spray testing and salt laden testing as described in most popular test specifications.
