GB/T 26548.7-2020
Hand-held portable power tools—Test methods for evaluation of vibration emission—Part 7:Nibbler and shears (English Version)

Scope: This part of GB/T26548 specifies the test method for the hand-transmitted vibration measurement of the handle of hand-held power-driven punching and shearing machines and scissors, and determines the type inspection procedure for the vibration of the gripping part of the handle when the machine is operated under the specified test conditions. The measured results are used to compare the vibration of different types of machines of the same type. This section applies to punching machines and scissors driven by compressed air or other means for cutting sheet metal or composite material (see Chapter 5). Note: In order to avoid confusion between "power tool" and "insert tool", "machine" is used throughout this section instead of "power tool".
