Champ d’application

This standard applies to rock drilling machines and pneumatic tools, including rock drills, explosion-proof electric rock drills, pneumatic picks, and pneumatic motors. It is mandatory for manufacturers producing these specific equipment types for the Chinese market. The standard does not apply to products outside the specified categories of drilling and pneumatic machinery. It references measurement methods outlined in GB/T 5898.

Exigences techniques

The standard establishes mandatory noise limits expressed as sound power levels in dB(A) for various categories of equipment. Compliance with these noise limits is essential for market access. It categorizes limits based on parameters such as machine mass, operating pressure, and product specifications. For instance, handheld rock drills and pneumatic picks have distinct thresholds based on their weight classes. For pneumatic tools, the standard specifies noise limits for equipment like pneumatic grinders, impact wrenches, and screwdrivers. The limits vary according to tool dimensions, such as grinding wheel diameter or screw tightening capacity. Manufacturers must ensure their products do not exceed the specified sound power levels. Additionally, the standard covers pneumatic motors, including piston and vane types, setting specific noise thresholds for different product series. The requirements are divided into mandatory and recommended sections, with the core noise limit tables being strictly enforced. It also references industry standards like JB/T 7737 for specific categorizations.

Méthodes d’essai

Noise measurement procedures must comply with GB/T 5898. Specific tools such as pneumatic drills, grinders, screwdrivers, and polishers are measured under no-load conditions. All other products, including rock drills and pneumatic picks, must be measured under load conditions to determine their sound power levels accurately.
