Clark Testing is providing compliance testing for equipment manufacturers throughout the United States with a fully accredited EMC laboratory. Clark Testing's EMC lab is 17025 accredited by A2LA and provide manufacturers with product certification and validation services as well as pre-compliance and compliance qualification for a wide range of industries. Its EMC compliance testing services are uniquely complimented by our vibration, seismic, shock and thermal aging capabilities. Clark is the lab of choice with a broad array of environmental testing capabilities enabling the clients to benefit from a single source for all their testing needs.
Clark Testing has several state of the art EMC/EMI chambers which are equipped to handle many industry requirements such as Military, Power Generation, Aerospace, Automotive, Telecom, and Medical. Whether your project is in the design, development, or pre-compliance and qualification stages, its experienced staff will provide you with top quality and timely results.
It is adding new capabilities to the Clark Testing laboratory monthly, targeting additional compliance standards to meet customers' need for to introduce new products to market quickly and with confidence.
The Railway electromagnetic environment is intricate. Multiple systems coexist and operate simultaneously to achieve safe and efficient transportation of goods and people. These systems like signaling or telecommunications are required to operate in an often harsh conditions created by the electrified railway and propulsion systems used. These systems and the increasing spectral crowding create electromagnetic interference (EMI) that needs to be dealt with to insure the safety and continued operation of today’s Trains.
Some common standards used for railway electromagnetic compatibility (EMC) are:
Nuclear Power and Power Generation
For over 25 years Clark Testing has supported the Nuclear Power industry providing testing and project management for all aspects of Nuclear EQ (equipment qualification) programs, from EMC to Seismic. With the integration of digital instrumentation and control (I&C) systems replacing the obsolete analog systems, the Nuclear Regulatory Commission (NRC) uses the test methods and levels from the Electric Power and Research Institute (EPRI) called out in the EPRI TR-102323. EPRI initially surveyed seven nuclear power plants in the United States to craft the emission limits and immunity levels. Since the initial release of EPRI TR-102323 in 1994 the NRC has created its own document, the NRC Regulatory Guide RG 1.180, released in 2000 and references the EPRI TR-102323. The guidance and test programs laid out in these documents is intended to control emissions from the next generation digital I&C equipment and electronic systems to minimize electromagnetic interference and establish immunity performance so the equipment can stand up in the Plant’s electromagnetic environment.
Some common standards used for Nuclear electromagnetic compatibility (EMC) are:
Military equipment and devices need to be able to withstand the most demanding requirements. From changing environments to active threats, commercial designs can be terribly inadequate for military applications. Because of the unique applications most military equipment will be subject to, Military EMC requirements were developed. MIL-STD 461 covers multiple platforms and installations with different limits and levels for each.
