The drive to protect the environment and to conserve natural resources has brought about a proliferation of regulations Tony Dibiase As the clamor for better and newer electronic products continues worldwide, there is increased concern over landfills accepting growing “mountains” of discarded electronic products. Consequently, global environmental regulatory compliance … [Read more...]
Test Beyond the Specs: Why Test Higher in Frequency and Field Strength?
IEC 61000-4-3: 2006’s frequency escalation Jason Smith and Pat Malloy, AR RF/Microwave Instrumentation Souderton, PA An increasing number of new and proposed EMC standards are pushing the upper frequency test limits higher into the microwave spectrum. The latest EMC standard released, IEC 61000-4-3: 2006, is no exception. The upper frequency test limit has been increased from … [Read more...]
Updates on the New Release of IEC 61000-4-3 Edition 3
Continuous efforts are needed to maintain a consistently repeatable test Jason Smith, AR Worldwide Souderton, PA The IEC 61000-4-3 standard on radiated electromagnetic field immunity has long been used in order to satisfy one key criterion of the European Union’s requirements for obtaining the CE mark. It is usually used in conjunction with a specific product test standard … [Read more...]
Expanded Line of IEC Inlet Filters Includes Higher Attenuation Models
An expanded line of IEC inlet filters from Schaffner EMC includes two new versatile models that offer up to 10 dB better attenuation than other versions in the series. The new FN9244 and FN9244E (with an integrated choke for additional EMI suppression on the earth line) offer a current rating of up to 15 A with an inductance up to 59.5 mH. These devices are well suited for use … [Read more...]
Life Enhancing Medical Products Achieve EMC Compliance
Surface cleanliness is critical to good coating adhesion for any coating process Rocky R. Arnold, Ph.D. WaveZero, Inc. Sunnyvale, CA Many medical product manufacturers achieve electromagnetic compliance (EMC) for their electronic devices by coating the inside of the plastic enclosures with a conductive material; for example, silver-copper particle loaded paint, electroplated … [Read more...]
ETSI Technical Report on EMC, Spectrum Use, and Implanted Medical Devices
The European Telecommunications Institute (ETSI) has issued ETSI TR 102 655 V1.1.1, which deals with electromagnetic compatibility and radio spectrum matters. This document defines new requirements for radio frequency spectrum usage for low-power active medical implants and their peripheral radio control systems. The report also proposes a concept that should permit a … [Read more...]
Reducing Ground Noise Emissions in Critical Electronic Equipment and Facility Ground Systems to Help Prevent Conducted EMI Problems
Many EMI problems involve emissions that circulate through electrical conductors within a facility and within equipment Philip F. Keebler and Kermit O. Phipps EPRI Knoxville, Tennessee Background The electromagnetic environment includes the areas inside and outside electrical and electronic equipment. The areas inside equipment include unused air spaces, circuit boards, cables … [Read more...]
Expanded Line of IEC Inlet Filters Comes in a Variety of Options
The new FN 9244 filters from Schaffner have expanded that company’s existing IEC filter inlet range. They are available in a variety of options and can be mounted in various ways. The line includes three attenuation classes: standard performance, high performance, and very high performance. All the new filters have been designed for a continuous operating voltage of 250 VAC, … [Read more...]
The IEC Advisory Committee on EMC (ACEC): Coordination of International EMC Standards
Since its formation, ACEC has developed a unique structure for EMC publications that is used to this day in the IEC and in other regional standardization organizations. While many EMC engineers are familiar with the electromagnetic compatibility (EMC) standards developed by the International Electrotechnical Commission (IEC), they are probably unaware of how the structure of … [Read more...]
