This Part is Part 1 of GB/T 28046. This Part is drafted in accordance with the rules given in GB/T 1.1-2009. This Part is prepared by using the redrafting method to amend and adopt ISO 16750- 1.2006 “Road vehicles - Environmental conditions and testing for electrical and electronic equipment - Part 1.General”. The technical differences between this Part and ISO16750-1.2006 are as follows. - ADJUST the order of the terms by bringing the test voltage before the supply voltage operating mode 3 UA, to make it more logical and easy to understand the standard; - Figure 1 uses the old version of the format, which is moderately simplified. Compared with ISO16750-1.2006, the editorial modifications of this Part are as follows. - DELETE the foreword of the International Standard. This Part is proposed by the National Development and Reform Commission. This Part is under the jurisdiction of the National Technical Committee on Automotive of Standardization Administration of China (SAC/TC 114). Drafting organizations of this Part.

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 28046.2 Road vehicles - Environmental conditions and testing for electrical and electronic equipment - Part 2.Electrical loads (GB/T 28046.2-2011, ISO 16750- 2.2006, MOD)3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.4 Classification by mounting locationFor some locations with special environmental conditions (e.g. exhaust system), no standard specifications can be given. In these cases, the load shall be stated in the instructions of the DUT.5 Operating modesThe DUT is electrically operated with test voltage, UB, as in a vehicle with shut-off engine and with all electrical connections made. The DUT is electrically operated with test voltage, UA, with all electrical connections made.6 Functional status classificationAll functions of the device/system perform as designed during the test. However, one or more of them may go beyond the specified tolerance. All functions return automatically to within normal limits after the test. Memory functions shall remain class A. One or more functions of a device/system do not perform as designed during and after the test and cannot be returned to proper operation without repairing or replacing the device/system.7 Tests and requirements7.1 General Unless otherwise specified, all tests shall be performed at room temperature (RT) of (23 ± 5) °C and a relative humidity of 25 % to 75 %. The test voltages shall be as shown in Table 1, unless other values are specified in the other parts or are agreed upon by the users, in which case such values shall be documented in the test reports.8 DesignationEach part of this series of standards accommodates special needs and situations through the use of Code Z “as agreed”. The use of Code Z should be restricted to cases where the supplier and/or vehicle manufacturer determine that the conditions or tests areAnnex A(informative) Example for a test sequence plan Figure A.1 shows an example for a test sequence plan.Annex B(informative) Example of life test/statement of reliability In addition to environmental loads, a product used in the vehicle will be subjected to loads induced by its own function, hereafter referred to as functional loads. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
