What we’re talking about
Test and Evaluation for Robustness Test and Evaluation for robustness of a product is an involved process. For electrical and electronic equipment an evolution of design engineering evaluation has been required to meet acceptable failure rates for fielded product. Instituting these test methodologies requires looking beyond a test to pass approach. Robustness in Military Applications
Military product testing is performed at various stages of a products development and service initiation. The earliest phase of this testing is known as Developmental Test and Evaluation. This phase is conducted by the product developer and includes a detailed regime of climatic, dynamic, EMI/EMC, and electrical compatibility test procedures. The United States Department of
Preparing for EMI Testing can save time and money. Most EMI tests do not provide the news we want to hear on the first trip, therefore preparing to go the lab then is a task that should be thought out. Emissions and immunity testing is an important part of your product development. Successful testing can
It wasn’t long ago that EMC Testing and Risk Management wouldn’t have appeared in the same sentence. Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) testing has normally been performed to meet the criterion established for a desired label. Once compliance testing has been passed, it’s off to market. Medical Equipment Safety Concerns A modern medical
The health effects of RF energy have been a concern voiced by many in recent years. Questions have been raised about the use of cell phones and the introduction of 5G. Now the military has raised concerns about the cognitive effects of radio frequency energy on pilots. U.S. Military Concerns About RF Noise Exposure A
Components for hypersonic applications are required for an increasing number of Department of Defense (DoD) projects. These components and assemblies must be able to function under very demanding circumstances. Typical stresses include altitudes exceeding 100,000 feet, rapid temperature changes, vibration, pyroshock, and acceleration. This provides unique challenges to designers and those involved in test and
Witnessing EMI/EMC testing is a complex task. Conducting this task properly can add value to your product development efforts. More often than not products fail their initial testing. Because of this, iterations of redesign and retest are required. This can result in budgetary and scheduling issues for your design team and delay getting your product
CVG Strategy Offers Product Test Management Services Product Test Management Services can assist in keeping product development schedules on track during the Covid-19 pandemic. Many product developers are already behind schedule due to lock downs. Sending engineering staff on travels to laboratory may not be a desirable option at this time. CVG Strategy can help
What Test Witnesses Need to Know About Accelerometers and Laboratory Testing Shock and Vibration analysis utilizing accelerometers and laboratory testing is a requirement for many commercial and defense standards. Because accelerometers provide the feedback to the excitation system, proper selection and placement is essential. To achieve optimal testing validity the test witness and test manager
Effective Test Program Management Requires Planning Effective Test Program Management can add value to product development when its true value has been identified. Too often product testing is left to the last moment, calls are made to test laboratories to ask what testing is required. Equipment and somebody from the engineering team is transported off
MIL-STD-810 Humidity MIL STD 810H Humidity Method 507 is a test method for evaluating products that are likely to be stored and/or operated in a warm, humid environment. MIL-STD-810 Environmental Engineering Considerations and Laboratory Tests is a Department of Defense (DoD) standard for military and commercial applications. It is a series of laboratory test method
What is an Electromagnetic Pulse? Electronic products have Electromagnetic Pulse Vulnerabilities that could cripple infrastructure systems across the planet. It is a serious concern that a number of agencies have reported on at length. The Critical National Infrastructure Commission report of 2008 is one such example that outlines some dire possibilities. Electromagnetic Pulses (EMP) can
The Growth of RF Spectrum Usage, EMI and Device Coexistance Increased reliance on radio frequency communication has created issues for Electromagnetic Interference (EMI) and Device Coexistence. Cellular devices and equipment using the Internet of Things (IoT) are major causes of this increase. This has effected product development strategies for both commercial and defense applications, particularly
The Need for Adequate Product Packaging Evaluation Product packaging evaluation is essential for a product’s success. Excellent design and proper manufacture mean little if the product delivered to the customer is damaged. Assessing packaging requirements requires an understanding of the product to be shipped fragility and a knowledge of the nature of transportation and storage
Product Compliance Testing Product compliance testing is a requirement for bringing products to market. These tests vary dependent on which global market sectors are being targeted. Requirements differ from product type to product type and standards are constantly being created and revised. It requires a great deal of effort to stay current on what testing
MIL-STD-810 H Places Added Requirements on Product Developers and Test Labs. MIL-STD-810 H was released in 2019. This revision not only included major alterations and in many cases complete rewrites of test methods and procedures but also revised requirements that effect the manner in which all testing must be conducted. These requirements effect both test
