Introduction
This document is the Class C standard specified in GB/T 15706.
For machines designed and manufactured in accordance with the requirements of category C, when the requirements of Class C standards differ from those in Class A or Class B standards
, The requirements in category C standards are superior to other criteria.
GB/T 25631 gives the hand-held and hand-guided mechanical vibration measurement of the general technical conditions, GB/T 26548 to the standard
Based on the vibration test method of hand-held portable machine, which stipulates the operation of the machine under the type test condition and the type test
Can other requirements. Its standard structure and chapter number and GB/T 25631 consistent.
GB/T 26548 of this part of the European standard EN60745 used in the first use of the sensor basic positioning method, due to extension
The reason for the continuation is inconsistent with GB/T 25631. The sensor is preferred to be placed near the area between the thumb and forefinger of the hand
The interference to this position is minimal for the operator to hold the machine.
It has been found that the rust generated by the derusting hammer and the needle shredder is greatly varied when used. The main source of vibration is the impact of the role,
The change in vibration is caused by changes in machine operation and the properties of the material being treated. Different supporting materials can also cause vibration
difference.
The test procedure used in this section is the machine operating on steel or concrete surfaces. In order to achieve better reproducibility of measurement results,
It is important that the material support and the insertion tool are in good condition when used. Workplace vibration exposure is assessed using ISO 5349
program of.
The value obtained is the type test value used to indicate the average of the upper quartile of the typical vibration of the machine in actual use. however,
The actual value sometimes changes greatly, depending on many factors, including the operator, the task, and the insertion of tools or consumables. The machine itself
The maintenance status may also be important. The effect of operator and operating procedures on low amplitude vibration is particularly important in real working conditions. because
This, less than 2.5m/s2 of the vibration radiation value, in the real working conditions are not recommended assessment. In this case, it is recommended to use 2.5m/s2 vibration
Momentum values are used to directly evaluate the vibration of the machine.
If a specific workplace requires a precise value, it is necessary to perform measurements in accordance with ISO 5349 in this working condition. In reality
The vibration value measured under the working conditions may be higher or lower than the value obtained in this part of GB/T 26548.

1 Scope
This part of GB/T 26548 specifies the hand-held power-driven derusting hammer and the needle shredder handle parts of the hand vibration vibration measurement
The test method determines the type checking procedure for the vibration of the handle grip at the time of operating the machine under the specified test conditions. Its measured
The results are used to compare the vibration of different types of machines of the same type.
This part applies to compressed air or other power driven, by means of reciprocating work tools or needle beam in a variety of materials to remove oil
Paint, rust, or scale, (see Chapter 5).
Note. In order to avoid confusion with the "power tool" and "insert tool", this part of the "machine" instead of "power tool".
