1.1 This test method covers the determination of the electromagnetic shielding effectiveness of glazings or glazing configurations. 1.1.1 The intended application of this test method is for glazings or glazing configurations to be evaluated for their transmittance or shielding capability to electromagnetic frequencies. 1.1.2 This is a component test. It is not applicable to full systems such as walls, floors, ceilings, shielded racks, or window systems. 1.1.3 The intention of this test method is to standardize a measurement procedure for glazings or glazing configurations, with and without coatings, films, interlayers, or other enhancements, as single or insulating units at a standard size and when mounted in a standardized frame. 1.1.4 This test method is to provide a means of generating data for the glazing or glazing configuration infills that can be used by the consumer, designer, and system manufacturer to understand the capability and contribution of glazings or glazing configurations to a system used for Electromagnetic Interference (EMI) security. 1.2 This test method is for use in the assessment of EMI transmittance for frequency ranges 100 kHz to 20 GHz. Specific test frequencies within these ranges are required. 1.3 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Section 8 on Hazards. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method provides measurement procedures for determining the electromagnetic shielding effectiveness of glazings and glazing configurations as a material. This test method specifies a method for comparing the glazings and glazing configurations as an infill component to allow comparison of between different infills. In addition, this test method is written to minimize variations in measured shielding effectiveness at a given frequency and test point regardless of test personnel, equipment, and test site. Therefore, the shielding effectiveness of a glazing or glazing configuration from any supplier can be determined. This test method specifies a minimum set of measurements over a frequency range to determine shielding effectiveness. 5.2 Source Fields— Performance of a shielded enclosure and glazing or glazing configurations are to be assessed for three source fields: magnetic, electric, and plane wave.
