Introduction

To standardize the vibration measurement method for handheld portable power tools, the International Organization for Standardization has published ISO 28927, a document with 13 parts.

This document is a Type C standard as defined in ISO 12100.

For machines designed and manufactured in accordance with the requirements of Class C standards, when the requirements of Class C standards differ from those in Class A or Class B standards, when the requirements of type C standards are met, they shall prevail over those of other types of standards.

GB/T 25631 provides the general technical conditions for the measurement of vibration radiation of handheld and hand-guided machinery. GB/T 26548 (all parts) Based on this standard, the vibration test method for handheld portable machines is given, and the operation of the machine under type inspection conditions and the vibration test of the type are specified.

The standard structure and chapter numbering are consistent with GB/T 25631 for other requirements for performance testing.

This document uses the basic positioning method of sensors first adopted in the European series of standards EN60745 (all parts).

The sensor is preferably placed in the area between the thumb and index finger of the hand because this position interferes least with the operator's grip on the machine.

The values obtained are type test values and are intended to represent the average of the upper quartile of typical vibration levels of the machine in actual use.

However, actual values can vary widely depending on many factors, including the operator, the work task, and the tools or consumables inserted.

The maintenance status of the machine itself may also be important. The influence of the operator and operating procedures on low-amplitude vibration is particularly important under real working conditions.

In this case, it is not recommended to use a radiation value lower than 2.5m/s2 to evaluate the vibration level under actual working conditions.

The vibration magnitude is used to evaluate mechanical vibration.

Vibration test method for hand-held portable power tools Part 13: Fastener driving tools

1 Scope

This document describes a test method for measuring hand-transmitted vibration in the handle of fastener driving tools.

Type inspection procedure for the vibration level of the handle grip.

This document applies to tools for driving fasteners using nails, staples or pins, driven by compressed air or other means.

This document applies to tools with single sequential fire, trigger fire, automatic reset trigger fire, or continuous trigger fire (see Figures 1 to 3).

This document is not applicable to tools operating in full sequential firing mode, as the intervals between individual firings are much longer.

However, Annex C provides informative guidance for comparing vibration values for different tools of this type (see Figures 4 and 5).

NOTE. Current knowledge does not allow any conclusions to be drawn regarding the physiological and pathological effects of single and continuous shocks, as well as their repetition rates.
