Aperçu de conformité

Cet aperçu n’est actuellement disponible qu’en anglais.

Champ d’application

This standard applies to internal combustion engine-powered earth-moving machinery, horizontal directional drilling machines, and forklift wheel loaders. It explicitly excludes electric earth-moving machinery as defined in GB/T 44254 and machines manufactured before the implementation of the specified noise limits. Manufacturers of diesel or gas-powered construction equipment must comply with this standard to enter the Chinese market.

Exigences techniques

GB 16710-2025 establishes the mandatory noise emission limits for earth-moving machinery to protect the environment and operator hearing. The standard specifies two primary categories of noise limits: external noise emission limits (sound power level) and operator position noise limits (emission sound pressure level). The limits are categorized based on the machine type (e.g., excavators, loaders, dumpers, rollers) and the engine net power. Compliance is enforced in two distinct implementation phases: Stage I starting from January 1, 2027, and a stricter Stage II starting from January 1, 2030. Manufacturers must ensure their equipment meets the respective tier limits based on the manufacturing date. The standard also references GB/T 25078 for recommended low-noise machine design methods.

Méthodes d’essai

The standard outlines specific testing procedures to measure noise emissions. For external sound power level determination, it references dynamic and stationary test conditions according to GB/T 25612 and GB/T 25614, with specific provisions for certain machines like scrapers and vibratory rollers under GB/T 25684.13-2021. For operator position emission sound pressure level measurement, it mandates the use of procedures defined in GB/T 25613 and GB/T 25615, depending on the machine type. Accurate testing according to these referenced standards is mandatory for certification.

Questions fréquentes

What products are regulated under GB 16710-2025?

It regulates internal combustion engine-powered earth-moving machinery, horizontal directional drilling machines, and forklift wheel loaders. Electric earth-moving machinery is excluded.

When do the new noise limits take effect?

The standard introduces a two-phase implementation. Stage I limits are effective from January 1, 2027, while the more stringent Stage II limits apply from January 1, 2030.

Does GB 16710-2025 replace an older version?

Yes, this is the second revision, replacing the previous GB 16710-2010. It includes updated noise limits, modified testing methods, and an expanded scope of applicability.
