GB/T 26548.4-2020 is the English-translated version of 手持便携式动力工具振动试验方法第4部分：直柄式砂轮机.

GB/T 26548.4-2020 is the Chinese standard "Hand-held portable power tools - Test methods for evaluation of vibration emission - Part 4: Straight grinders".

Its scope clause reads: This part of GB/T 26548 specifies the test method used to measure the vibration of the handle of a straight shank grinder, and determines that the specified test method is installed.

The type test procedure for the vibration of the handle when the wheel inspection machine is running under no load.

This part is suitable for driving by compressed air or other methods, using type 1 flat grinding wheel, type 4 double bevel grinding wheel and type 16 (cone with core) Grinding head), 18 type (cylindrical grinding head with core), 18R type (half spherical grinding head with core), 19 type (elliptical cone grinding head with core) with core grinding head and wire brush in Hand-held machines for grinding and surface finishing operations on various materials (see Chapter 5).

The measured results are used to compare different forms of the same The amount of vibration of the model machine. This section does not apply to mold grinders where the insert tool is installed on the chuck.

Note 1.The typical machines covered by this section are shown in Figure 1~Figure 3. Note 2.In order to avoid confusion between the terms "power tool" and "insertion tool", "machine" is used instead of "power tool" throughout this section. Its clauses include generalrequirements).

1 Scope

This part of GB/T 26548 specifies the test method used to measure the vibration of the handle of a straight shank grinder, and determines that the specified test method is installed.

The type test procedure for the vibration of the handle when the wheel inspection machine is running under no load.

This part is suitable for driving by compressed air or other methods, using type 1 flat grinding wheel, type 4 double bevel grinding wheel and type 16 (cone with core)

Grinding head), 18 type (cylindrical grinding head with core), 18R type (half spherical grinding head with core), 19 type (elliptical cone grinding head with core) with core grinding head and wire brush in

Hand-held machines for grinding and surface finishing operations on various materials (see Chapter 5). The measured results are used to compare different forms of the same

The amount of vibration of the model machine.

This section does not apply to mold grinders where the insert tool is installed on the chuck.

Note 1.The typical machines covered by this section are shown in Figure 1~Figure 3.

Note 2.In order to avoid confusion between the terms "power tool" and "insertion tool", "machine" is used instead of "power tool" throughout this section.
