1 Scope

GB/T 32800.11-2023 is Part 11 of the Chinese safety series for hand-held non-electric power tools and covers nibblers and shears. These are pneumatic tools that cut sheet metal by punching or shearing it, and their hazards are specific: the cutting head is close to the hand steadying the workpiece, the offcut leaves as a stream of hot sharp slugs, and the sheet itself has an edge that will cut the operator whatever the tool does. They also vibrate and are loud enough to matter over a working day. The standard sets the safety requirements and protective measures for the general case, machinery safety, thermal safety, noise reduction, vibration, materials and substances, ergonomics and the control devices, then the inspection, with the general test conditions and the tests for noise, vibration and unexpected start, followed by the information for use. It took effect on 1 October 2023.

This document applies to hand-held non-electric power tools for punching and shearing through reciprocating motion (hereinafter referred to as "punching and shearing machines and shears") knife"): Punches and shears can be driven by compressed air, hydraulic oil or an internal combustion engine, with or without suspension (e:g: balancing devices) It can be used by one operator with support of one or two hands:

Note 1: At the time of publication of this document, it was not known that there were punching and shearing machines and scissors driven by internal combustion engines: Once the existence of such power tools is confirmed, this document will be reviewed Amended to incorporate it: This document applies to the following products:

--- punching and shearing machine;

Note 2: See Appendix B for examples of punching and shearing machines and scissors: This document does not apply to special requirements and modifications for punching and shearing machines and scissors installed on the holding device: This document covers, in addition to the use of punching and shearing machines and scissors in potentially explosive atmospheres, reasonably foreseeable misuse in the intended use and in the factory All noteworthy hazards, hazardous conditions or hazardous occurrences when using the tool under the specified conditions:

Note 3: EN13463-1 gives the requirements for the use of non-electrical equipment in potentially explosive atmospheres:
