Scope

This document specifies the instruments and measurement accuracy required for measuring the dynamic noise of pure electric off-road dump trucks (hereinafter referred to as "off-road dump trucks"), the test environment, test preparation, determination of test results, preparation of test reports, and other aspects. It describes the measurement methods of A-weighted sound power level environmental emission noise and A-weighted time-averaged sound pressure level driver position emission noise under dynamic test conditions, and establishes the measurement procedures.
This document is applicable to the dynamic noise detection of off-road dump trucks, and other derivative products can be implemented in accordance with it.
