Scope

This document specifies the instruments and measurement accuracy required for measuring the dynamic noise of pure electric hydraulic excavators (hereinafter referred to as "excavators"), the test environment, test preparation, determination of test results, preparation of test reports, etc. 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 crawler excavators, and other derivative products can be referenced for implementation.
