K nowing which standard to use is very important when selecting a test method for evaluating a product. When selecting a specification, the user needs to take into consideration the purpose of the standard. A good example is CISPR 12 and CISPR 25.Both CISPR 12 and CISPR 25 include radiated emissions measurements for vehicles. However, there are a few fundamental differences that the user CISPR 25 contains limits and procedures for the measurement of radio disturbances in the frequency range of 150 kHz to 2 500 MHz. The standard applies to any electronic/electrical component intended for use in vehicles, trailers and devices. Refer to International Telecommunications Union (ITU) publications for details of frequency allocations. Abstract. CISPR 25:2021 contains limits and procedures for the measurement of radio disturbances in the frequency range of 150 kHz to 5 925 MHz. This document applies to vehicles, boats, internal combustion engines, trailers, devices and any electronic/electrical component intended for use in vehicles, boats, trailers and devices. See CISPR 12. See CISPR 12-4. Test limits and methods of measurement of radio disturbance characteristics of vehicles and devices, broadband and narrowband, 150KHz to 1000MHz. RE. RI: CISPR 25. See CISPR 25: See CISPR 25-5: Performance levels and methods of measurement of magnetic and electric field strength from electric vehicles, 9kHz to 30MHz CISPR 25:2008 contains limits and procedures for the measurement of radio disturbances in the frequency range of 150 kHz to 2 500 MHz. The standard applies to any electronic/electrical component intended for use in vehicles, trailers and devices. This document is available in either Paper or PDF format. LISN Automotive LISN to CISPR25 LINE IMPEDANCE STABILISATION NETWORKS THE FULL SPECIFICATION ACCESSORY FOR AUTOMOTIVE CONDUCTED EMISSIONS TESTING • Two versions, rated to 25 or 100A continuous. • Rigorous, accredited calibration to 108MHz • Full calibration data included with each LISN. • Commercial, military and other special types available to order. What is shown in Table 1 is the conducted EMI emission limits from 150 kHz to 108 MHz for vehicle components, which is described in standard CISPR 25 (GB/T 18655-2010) complied by measurements International Standard CISPR 25 has been prepared by CISPR subcommittee D: Electromagnetic disturbances related to electric/electronic equipment on vehicles and internal combustion engine powered devices. This third edition cancels and replaces the second edition published in 2002. This edition constitutes a technical revision. Keywords: CISPR 25, ALSE Validation, Site Attenuation, Test Bench grounding Introduction The results of a radiated emission measurement depend on the wave propagation characteristic of the test site. It is required to define this characteristic to ensure a good reproducibility and to obtain similar results from different test facilities.
