Escopo e aplicabilidade

This standard applies to all types of self-propelled grain combine harvesters operating in the agricultural sector. It specifically regulates both dynamic environmental noise and noise levels at the operator's position. Compliance is mandatory for all manufacturers distributing these machines in China.

Requisitos técnicos

GB 19997-2005 establishes mandatory noise emission limits for combine harvesters based on their cab configuration. The standard categorizes operator environments into three distinct types: enclosed cabs (fully sealed with climate control), general operation cabs (fully enclosed without AC), and simple cabs or open stations (providing only basic weather protection). The standard sets specific maximum allowable decibel levels for both dynamic environmental noise and operator-position noise. Manufacturers must ensure their equipment does not exceed the prescribed dB(A) limits for their specific cab category. The strictest limits are applied to premium enclosed cabs, while more lenient thresholds are given to simple or open cab configurations.

Métodos de ensaio

Noise evaluation under this standard relies on established industry methodologies. Dynamic environmental noise is measured according to the procedures outlined in JB/T 6268 (Self-propelled harvesting machinery noise determination method). Operator-position noise is measured following the acoustic measurement guidelines specified in GB/T 16955.

Perguntas frequentes

What products are regulated under GB 19997-2005?

This standard regulates the noise emitted by all types of self-propelled combine harvesters used in grain harvesting. It is mandatory for all manufacturers targeting the Chinese market.

How does GB 19997-2005 classify different types of combine harvesters?

The standard classifies harvesters into three categories for noise limits: enclosed cabs (with climate control), general operation cabs (simple enclosure without AC), and simple cabs or no cab (open operator stations).

What testing standards are referenced for noise measurement in GB 19997-2005?

Dynamic environmental noise is measured according to the procedures specified in JB/T 6268, while noise at the operator's position is measured following the GB/T 16955 acoustics standard.
