GB/T 26548.5-2025 Hand-held portable power tools—Test methods for evaluation of vibration emission—Part 5:Drills and impact drills

Scope

This document describes the test method for measuring hand-transmitted vibration radiation at the handle of hand-held power-driven drills and impact drills, and determines the type-testing procedure for the amount of vibration at the handle of drills equipped with drill heads. The results obtained are used to compare machines of the same type but different models.
This document is applicable to straight-shaft drills, gun-handle drills, and angle drills driven by pneumatic or other power sources, which drill holes in various materials through rotating and impact action (see Chapter 5).
This document is not applicable to heavy-duty drills driven by screws or drills powered by internal combustion engines.
Note: To avoid confusion between "power tools" and "insertion tools", this document uses "machines" throughout to replace "power tools".
