The issuing authority shall not be held responsible for identifying any or all such patent rights. Road vehicles - Test method of electrical disturbances from conduction and coupling - Part 1: Definitions and general considerations 1 Scope This document specifies the test conditions, functional characteristic state classification for electrical transient conducted emissions and immunity tests of electrical/electronic components. This document applies to electrical/electronic components for M, N, O, L vehicles. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Parts of GB/T 21437 give test methods and procedures, test instruments and limits for electrical disturbances of electrical/electronic components caused by conduction and coupling. They provide a standard specification between vehicle manufacturers and parts suppliers. Immunity tests for complete vehicles are usually carried out by vehicle manufacturers. Laboratory test methods are used in the research development and quality control process of electrical/electronic components. The tests in each part of GB/T 21437 are "bench tests". Some of the bench test methods require the use of artificial networks. This is for comparability between the results of different laboratories. These test results can guide component and system development and facilitate the resolution of production-phase problems. Protecting components and systems from potential harassment is the basis for complete vehicle validation. It needs to understand the correlation between laboratory electrical/electronic component testing and real vehicle testing. A bench test with a test pulse generator can be used to evaluate the immunity of components to transients on power or data lines. The methods given in the various parts of GB/T 21437 cannot yet cover all transient forms generated in the vehicle. The test pulses described in different parts are only characteristic of typical pulses. ......

GB/T 21437.1-2008/ISO 7637-1.2002 Book GB/T 21437.1-2008/ISO 7637-1.2002 4 GB/T 21437 overall goals and practical applications GB/T 21437 is concerned with the problem of transient disturbances in road vehicles and their trailers. It involves transient launches, instants along the wire State conduction and the potential sensitivity of electronic components to electrical transients. The test methods and procedures, test instruments and limits given in the various sections are intended to simplify the electromechanical parts caused by conduction and coupling. The standard specification for disturbances provides a basis for agreement between the vehicle manufacturer and the component supplier to help rather than constrain. Due to the secrecy of the prototype or a large number of different models, the immunity test of the vehicle is usually only carried out by the vehicle manufacturer. because Laboratory test methods are used by vehicle manufacturers and equipment manufacturers to test the development and quality control of electronic components. The tests specified in the different sections are referred to as "stand test." Some of the bench test methods require the use of a manual network that can provide different Comparable results between laboratories. At the same time, these tests also give the basis for device and system development and can be applied in the production phase. Protecting the system from potential harassment should be considered part of the vehicle's confirmation. Understand the correlation between laboratory testing and real vehicle testing It is very important. A bench test using a test pulse generator can be used to evaluate the transient immunity of the device to the power or data lines. this method It is not possible to cover all transient forms produced in a vehicle, and the test pulses described in the different sections are only typical pulse characteristics. Some devices are particularly sensitive to some characteristics of electrical disturbances such as pulse repetition rate, pulse width, and time relative to other signals. a standard The test cannot be applied to all situations. For this particular, potentially sensitive device, it is necessary for the designer to design and A deep understanding of the function to anticipate appropriate test conditions. The device under test shall be subjected to the test applicable to the device specified in the relevant part of GB/T 21437. For those who need to reproduce the measured equipment Tests on the use and installation location should be written into the test plan to help ensure that potentially sensitive components and systems are technically and economically Line optimization design. 2002.
