  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Electromagnetic Pulse

    EMP - Keystone Compliance

    An electromagnetic pulse (EMP) is a short burst of electromagnetic energy that can be extremely damaging to electronic equipment. EMP energy can be transferred in the form of electromagnetic radiation, an electric field, electrical conduction or a magnetic field. Since EMPs have a short duration, their impact can occur across large ranges of frequencies. EMPs can be produced naturally, occur from man-made equipment. Natural EMPs include lightning strikes and electrostatic discharges (ESD), geomagnetic storms/coronal mass ejections of solar origin. Man-made EMPs include power line surges, pulses created by ignition systems, nuclear electromagnetic pulses (NEMP) and non-nuclear electromagnetic pulses (NNEMP).

  • 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.

  • 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.
