9、 Function performance status classification (FPSC).22 ISO 11452-4:2005(E) iv ISO 2005 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is nor
10、mally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in
11、the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepar
12、e International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that som
13、e of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11452-4 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. This third editio
14、n cancels and replaces the second edition (ISO 11452-4:2001), which has been technically revised. ISO 11452 consists of the following parts, under the general title Road vehicles Component test methods for electrical disturbances from narrowband radiated electromagnetic energy: Part 1: General princ
15、iples and terminology Part 2: Absorber-lined shielded enclosure Part 3: Transverse electromagnetic mode (TEM) cell Part 4: Bulk current injection (BCI) Part 5: Stripline Part 7: Direct radio frequency (RF) power injection The radiating loop method is to form the subject of a future part 8.

16、-4:2005(E) ISO 2005 All rights reserved v Introduction Immunity measurements of complete road vehicles are generally able to be carried out only by the vehicle manufacturer, owing to, for example, high costs of absorber-lined shielded enclosures, the desire to preserve the secrecy of prototypes or a
17、 large number of different vehicle models. For research, development and quality control, a laboratory measuring method can be used by both vehicle manufacturers and equipment suppliers to test electronic components.

18、cles Component test methods for electrical disturbances from narrowband radiated electromagnetic energy Part 4: Bulk current injection (BCI) 1 Scope This part of ISO 11452 specifies bulk current injection (BCI) test methods for determining the immunity of electronic components of passenger cars and
19、commercial vehicles regardless of the propulsion system (e.g. spark-ignition engine, diesel engine, electric motor). The electromagnetic disturbances considered in this part of ISO 11452 are limited to continuous narrowband electromagnetic fields. See ISO 11452-1 for general test conditions. 2 Norma

21、ent test methods for electrical disturbances from narrowband radiated electromagnetic energy Part 1: General principles and terminology 3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO 11452-1 apply. 4 Test conditions The frequency range of the BCI te
22、st method is a direct function of the current probe characteristic. More than one type of current probe may be required. For testing automotive electronic systems, the applicable frequency range of the BCI test method is 1 MHz to 400 MHz. The user shall specify the test severity level(s) over the fr
23、equency range. Suggested test levels are included in Annex E. Standard test conditions shall be according to ISO 11452-1 for the following: test temperature; supply voltage; ISO 11452-4:2005(E) 2 ISO 2005 All rights reserved modulation; dwell time; frequency step sizes; definition of test severity l
