Geltungsbereich und Anwendbarkeit
This standard establishes the noise emission limits for earth-moving machinery as defined in GB/T 8498. It applies to 11 specific categories of equipment, including bulldozers, loaders, excavators, dump trucks, scrapers, motor graders, pipelayers, trenchers, backfill compactors, and rollers. This standard does not apply to machines manufactured before the specified implementation dates of the noise limits.
Technische Anforderungen
Chapter 4 of this standard contains the mandatory noise limit requirements, while the remaining clauses are recommended. The standard sets strict boundaries for both exterior noise emissions and operator-position noise levels. For exterior noise emissions, the standard specifies maximum allowable sound power levels based on the machine category and the engine's net power. Manufacturers must ensure their products do not exceed the specified sound power limits when tested under dynamic conditions. The limits are calculated using specific logarithmic formulas based on the engine's net power ($P$) for higher-power machinery. For operator-position noise, the standard dictates the maximum emission sound pressure levels at the driver's seat, specifically for machines equipped with a driver's cab. The standard introduces a two-tier phase-in approach for noise reduction. Compliance is required in two stages: Stage I (effective from January 1, 2012) and a more stringent Stage II (effective from January 1, 2015).
Prüfverfahren
Noise evaluation must be conducted according to referenced national standards. Exterior noise emissions are measured using the dynamic test conditions specified in GB/T 25614 (identical to ISO 6395). Operator-position noise is measured using the dynamic test conditions outlined in GB/T 25615 (identical to ISO 6396). Additionally, the engine net power, which determines the applicable limit category, must be verified according to GB/T 16936.
Häufige Fragen
What products are regulated under GB 16710-2010?
The standard regulates 11 categories of earth-moving machinery, including bulldozers, loaders, excavators, dump trucks, scrapers, motor graders, pipelayers, trenchers, backfill compactors, and rollers.
Are there any updates from the previous version of GB 16710?
Yes, this version replaced GB 16710.1-1996. Key updates include expanding the regulated machine types from 4 to 11 categories, modifying the engine power classifications, and introducing a two-tier phase-in system for stricter noise limits (Tier I and Tier II).
How does GB 16710-2010 differ from ISO standards?
The standard references testing methodologies identical to international standards such as ISO 6395 and ISO 6396 for dynamic test conditions. However, the specific noise emission limit values and the two-tier implementation schedule are tailored to Chinese environmental and manufacturing requirements.
