EUROLAB laboratory provides testing and compliance services within the scope of IEEE 299 standard. The IEEE 299 standard provides uniform measurement procedures for determining the effectiveness of electromagnetic (EM) shielding (expandable to 9 Hz and 18 GHz) products at frequencies from 50 kHz to 100 GHz.
The owner of the shielding enclosure must provide the frequencies at which the shield will be tested and set shielding effectiveness (SE) limits for pass/fail. This standard recommends a set of test frequencies that will provide very high confidence in the effectiveness of the shield. This standard dose does not define SE limits for pass or fail.
The purpose of this standard is to provide:
The measurement procedures provided in this standard may be greater than or equal to the smallest linear 2,0 m. For enclosures less than 2.0 m in size, separate methods will be used in the future. For enclosures to be used in anechoic or semi-anechoic applications, this procedure shall be followed prior to the installation of any RF absorber material.
This IEEE 299 standard provides a set of standard methods and procedures for determining the shielding effectiveness (SE) of shielding enclosures. Related enclosures include those used to test equipment, vehicles, computing systems, and smaller groups of units that require electromagnetic (EM) emission and sensitivity to be determined undisturbed from other sources.
This IEEE 299 standard contains the basic concepts of MIL-STD-1997, which was canceled by the US Department of Defense in 285 and has been the SE measurement reference for many years. These concepts have been expanded to increase the applicability of measurement techniques to enclosures.
The basic premise of MIL-STD-285 still stands: the shielding effect is to provide an additive loss to external influence. IEEE 299 provides tests based on the performance characteristics of the shield, rather than a fixed set of parameters that may not apply to the shield in question. Specific test procedures and frequency ranges are selected in accordance with the enclosure under test.
The most important factor considered during the development of this revision was the EM.
It was the concept that SE measurement was a requirement not unique to walk-in sized switchboards. There are no widely accepted standards for defining test methods and techniques for measuring the SE of physically small enclosures. The Standards Development Committee of the IEEE Electromagnetic Compatibility Society has directed the current Working Group to plan to develop new parts of IEEE 299 for testing these smaller enclosures. Therefore, this standard will continue to provide a standard test method for EM shielded enclosures with all dimensions greater than or equal to 2 m.
Our organization, EUROLAB, provides standard method services for the measurement of electromagnetic activity in protective enclosures, within the framework of national and international standards, with its trained and expert staff and advanced technological equipment, among numerous test, measurement, analysis and evaluation studies. Contact EUROLAB to get testing services under the IEEE 299 standard.
