  • 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:

  • 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.

  • 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.

  • 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.

  • 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.

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.

  • 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.
