If not specified, the test parameter for relative humidity shall be set at 50 5% and voltage set to Unom, where Unom, is nominal voltage. The d
27、riving test can be performed in all types of weather. However, in situations where severe weather makes certain driving maneuvers unsafe, modules using those maneuvers shall be postponed until road conditions improve. 4.2.2 Test Conditions. Deviations from the requirements of this standard shall hav
