Описание (английский):

ISO 6395:2008 specifies a method for determining the noise emitted to the environment by earth-moving machinery, measured in terms of the A-weighted sound power level while the machine is operating under dynamic test conditions. It is applicable to earth-moving machinery as specified in Annex A and as defined in ISO 6165.

Overview

ISO 6395:2008 specifies a repeatable test method to determine the A-weighted sound power level emitted to the environment by earth-moving machinery operating under dynamic test conditions. It gives procedures for measuring noise from machines defined in ISO 6165 (e.g., excavators, dozers, loaders, rollers) using a simulated dynamic sequence to produce representative, reproducible sound power data for compliance, product comparison, and noise-reduction work.

Key Topics and Requirements

Scope and definitions: Defines key quantities such as time-averaged A-weighted sound pressure level (LpA,T), A-weighted sound power level (LWA) and the machine basic length (l) and machine centre point used to position the measurement hemisphere.

Instrumentation: Recommends integrating/averaging sound level meters (IEC 61672-1 class 1 preferred) capable of the required averaging and data acquisition.

Test site and environment:

Three allowed ground types: hard reflecting plane (concrete/asphalt), combination reflecting plane + sand, and all-sand plane.
For hard reflecting planes, environmental correction K can be assumed ≤ 0.5 dB and set to 0 dB when obstacles are negligible. For sand sites K must be determined and applied.
Requirements for background noise correction, climatic conditions, and instrumentation operating limits are specified.

Measurement geometry:

Use a hemispherical measurement surface with microphone positions defined relative to the basic length and machine centre point.
Size of the measurement hemisphere, microphone placement and machine positioning are standardized to ensure repeatability.

Machine operation:

Procedures for engine speed, fan speed, travel modes and required attachments (manufacturer’s production configuration) are provided to simulate dynamic operation.

Calculation and reporting:

Step-by-step measurement procedure, calculation of LWA including corrections (environmental and background), uncertainty declaration and reporting format are specified.

Annexes: Normative annexes cover basic length and machine-specific test details (excavators, dozers, loaders, dumpers, graders, rollers, etc.), plus guidance and declaration templates.

Applications - Who Uses ISO 6395:2008

Manufacturers of earth-moving machinery for type testing, compliance with noise regulations and product data sheets.

Test laboratories and certification bodies performing sound power measurements under dynamic conditions.

Environmental and occupational noise engineers using measured LWA values for site planning, mitigation and comparative assessments.

R&D teams conducting noise-reduction design and verification.
