Surges are an everyday occurrence in the real world and can have major negative affects to electronic devices. These effects range from data corruption, permanent damage to a device and in some cases even fire. Surges can occur for a variety of reasons but the most common causes of electrical surges are:
EN 55022: 2010 was superseded by EN 55032:2012 on 05/03/2017 and ceased to give presumption of conformity with the essential or other requirements of the relevant Union legislation. So why does EN 55022 no longer give presumption of conformity to the EMC Directive 2014/30/EU?
When considering the how to approach the compliance for the RCM Radiocommunications requirements for Australia we need to consider the the ACMA requirements and also the product itself, i.e. what type of transmitter or receiver the product is.
Electromagnetic compatibility (EMC) should be considered at the design stage for electrical and electronic products, long before the EMC compliance testing stage. However sometimes EMC and EMI evaluation and simple checks are overlooked. This check list provides a quick glance at what should be considered.
Electromagnetic Interference (EM) and Electromagnetic Compatibility (EMC) are vital terms for product development and regulatory testing of electronic devices for companies all over the world, including Australia. Although these terms bear very different meanings, they are generally interchanged and the two have become easily confused.
Should radiated emissions testing be performed on a 30m, 10m, 3m or 1m test site has been a controversial debate for a long time in the world of electromagnetic compatibility (EMC) compliance testing. In this article we will skip military (MIL STD 461, RTCA DO-160 etc) and automotive (CISPR 25) type testing as this testing is typically conducted at a 1m distance over the entire frequency (usually 10kHz to 18GHz).
Electromagnetic Compatibility (EMC) is the ability of an electronic device to exist in an electromagnetic environment without causing interference to or being interfered with by other electronic devices within that environment. EMC is typically broken down into two categories:
