  • Lightning Testing and Surge Immunity Testing

    Keystone Compliance

    Keystone Compliance offers engineering services for standard and custom lightning transient immunity testing requirements and surge immunity testing requirements. Lightning testing can be completed in single-stroke, multiple-stroke and multiple-burst testing. Direct lightning testing is typically required for exterior aircraft systems. Indirect lightning testing is required for most aircraft electronics, both internal and external. Indirect lightning simulates secondary currents and voltages that travel through circuitry and cabling. The testing is also referred to as a surge immunity test.

  • 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:

  • Solar Radiation Testing

    Keystone Compliance

    Solar radiation test setups are custom designed for each test setup. Solar arrays can be provided for small or large test articles. Arrays are designed and calibrated prior to placement of the test article. Testing takes place within any of our various temperature chambers. Solar arrays are microprocessor controlled and are capable of delivering greater than the 1,200 watts per meter squared as required by most commonly used test specifications. Custom programs can be designed to simulate real world test cycles of sunrise to sunset. Keystone Compliance offers Solar radiation testing for heating effects only.

  • Shielding Effectiveness Test

    Keystone Compliance

    Shielding effectiveness testing determines the ability of material to reduce the electromagnetic field in a space by blocking the field with barriers made of conductive and/or magnetic materials. Shielding effectiveness testing can be applied to a broad range of radio frequencies. Electromagnetic Shielding is typically applied to both enclosures and cables. The shielding can reduce the coupling or radio waves, electromagnetic fields and electrostatic fields. The amount of reduction can vary based on the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest. Also impacting the effectiveness of the shielding is the size, shape and orientation or apertures in a shield to an incident electromagnetic field. Electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as RF Shielding.

  • Shock Testing

    Keystone Compliance

    Keystone Compliance offers shock testing on our electrodynamic shakers as well as through the use of our pneumatic shock machine. Additionally, Keystone Compliance possesses the necessary equipment to produce and analyze Shock Response Spectrum (SRS) shock events. The latest revisions of many federal and military specifications are requiring, or offering, shock response spectrum as an alternative to typical classical shock testing.

  • 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.

  • Climatics Testing

    Keystone Compliance

    Keystone Compliance operates an altitude test chamber capable of simulated altitudes up to 100,000 feet while providing temperature conditioning from -70 to +100 degrees Celsius.

  • 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.

  • Ingress Protection: Dust Protected and Dust Tight (IP5X & IP6X)

    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 dust. These tests are numbered IP5X and IP6X. The first digit, in the case of dust protected, would always be a 5, and in the case of dust tight, would always be a 6. The first digit, represented by the “X”, ranges from 0 to 9 and specifies the protection from liquid.

  • Wind and Rain Testing

    Keystone Compliance

    Keystone Compliance operates wind and rain generators that are capable of producing wind speeds exceeding 160 mph. Rain fall rates are practically limitless but are typically controlled to 4”, 6”, or 8” per hour. Automated turn tables are often utilized to ease testing of large products. Multiple generators can be setup to provide a large coverage area. Custom setups are a specialty for Keystone Compliance personnel when setting up a wind driven rain test.

  • Thermal Shock Testing

    Keystone Compliance

    Keystone Compliance currently offers thermal shock testing in two chambers. Both chambers offer approximately five-second transition times and can accommodate smaller products. We also have the ability to provide thermal shock testing to larger products by using two separate walk-in temperature and humidity chambers. If you have a large unit, we can likely find a way to test it.

  • Drop Testing

    Keystone Compliance

    Drop testing, per MIL-STD 202 Method 203, is used to determine the effects on component parts of random drops tested and repeated impact due to handling, shipping, and other field service conditions. This drop testing is an accelerated test designed to indicate structural and mechanical weaknesses of types not necessarily detected in shock and vibration tests. Package drop testing can help determine the survivability of a product’s packaging and help manufacturers identify potential warranty issues from poor packaging or improper handling instructions.

  • EMI Site Survey

    Keystone Compliance

    An EMI site survey is an independent assessment of the potential Electromagnetic Interference (EMI) risks that might interfere with an implantable electrical device such as a pacemaker or defibrillator. The assessment should be completed by a qualified and accredited independent test lab such as Keystone Compliance and in collaboration with the employer, manufacturer of the device, patient and physician. A site survey is conducted by taking various electromagnetic measurements throughout the facility. Keystone Compliance uses a broad range of industry-accepted standards and specifications to determine which electromagnetic fields exist. Following completion of the on-site survey, Keystone Compliance provides the customers with a detailed site survey report that will help identify EMI sources and zones with the potential to interact with an implantable electrical device. This information should then be shared with the physician and employer to develop an action plan to reduce potential negative effects to the patient’s health.

  • Dynamics Testing

    Keystone Compliance

    Keystone Compliance is a drop test lab capable of testing products to the drop testing requirements of various test standards including the random drop test in MIL-STD 202. Our drop test machine is capable of precise drops from different heights at different angles and onto different surfaces. Our three shakers can simulate loose cargo test conditions that might be experienced as a product is in transit.

  • Electrostatic Discharge Testing / ESD Testing

    Keystone Compliance

    Electrostatic discharge testing, also known as ESD testing is an essential test for many product. Electrostatic discharge can cause a number of problems including but not limited to mechanical failures, coal dust explosions, fuel vapor explosions and bodily injury. ESD is the sudden transfer of electricity between to electrically charged objects. This electrostatic transfer can be caused by contact, dielectric breakdown or an electrical short. ESD testing simulates various electrostatic impacts that equipment might experience either during transit or operation. The impact of electrostatic discharge can be significant whether the ESD even is so slight that is undetectable by hearing or sight or as spectacular as electrical sparks or lightning. An electrostatic discharge test determines whether a product is in compliance with its ESD protective area and procedures. Electronics manufacturers must identify ESD-reducing measures when their products are either susceptible to ESD or likely to create ESD. These measures can include establishing electrostatic protective areas that are free of static, controlling humidity, using measures to eliminate charging such as avoiding highly charging materials and taking steps to remove static such as grounding human workers or requiring antistatic devices. An ESD test confirms that the equipment correctly operates per the test requirement and the manufacturer’s operating procedures.
