Test Plans and Procedures

Engineering Design, Test Plans and Procedures are integral parts of a successful compliance program. VEC can develop and tailor specific Test Plans for your product and program. A detailed Plan considers the end-use of the product as well as the regulatory and specifications required.

Defining test levels, test methods, operational requirements and monitoring are all critical to a well-organized test plan. We have prepared plans for MIL-STD 461, 464 and 810 applications, the Nuclear Power Industry (EPRI TR-102323), tailored procedures for the wireless industry and evaluation plans for compliance with European Directives.

Engineering Design Services

Our engineering services include engineering design and analysis for: emissions control, product safety, product performance, RF radiation prediction and antenna-to-antenna coupling.

The design and support should start early in the process and consists of a review of schematic, layout and parts lists and bills of materials. Comprehensive review before layout and manufacturing can save time and cost during compliance testing.

Critical aspects of EMC design include an analysis of critical nets on PCBs, impedance and termination control of high-speed circuits. Power supply, power and ground plane design is crucial for low-noise performance and a high degree of immunity.

We also specialize in electromagnetic (EMI/RFI) design for architectural and engineering projects including shielding design and grounding. We offer technical advice on lightning protection, overvoltage, surge design and analysis as well as perform forensic investigations and failure and root-cause analysis.

Laboratory Support Services

Our team has performed thousands of EMC, Safety, Wireless and Environmental tests on a variety of equipment, from Military System to Enterprise Communications and Consumer products.

We supply design and troubleshooting support during testing to quickly turn failures into successes. Specific support includes board and box-level consulting to determine the root cause of failure and engineered solutions to achieve compliance. Leveraging decades of years of testing, we can pinpoint solutions to save you time and money in the lab.

Working with our laboratory partners, we support on-site and laboratory testing to assist you with tricky EMI problems, product safety compliance, and mechanical fatigue and failure.
