Power Tools Basic Requirements

Power tools should be able to be used normally under the following environmental conditions

  • The altitude should not exceed 1000m

  • The temperature of the air medium does not exceed 40°C

  • The relative humidity of the air is not more than 90% (25°C)

Power tools used in special environmental conditions such as tropics, plateaus, underwater, and explosive gases should also meet the corresponding special regulations.

The power tools should be able to work under the condition that the difference between the power supply voltage and the rated voltage does not exceed ±10%.



In addition to good working performance, high labor productivity and sufficient service life, electric tools should also meet the following requirements.

  • Safe and Reliable

In order to prevent electric shock accidents and mechanical hazards in the use of power tools, all accessible metal parts of Class I power tools must be reliably grounded.

Power tools with water source must be designed with a rated voltage not greater than 115V, and be isolated from the power supply.

The structure and installation position of the power switch should be convenient for the power tool to turn on and off the power in time.

There should be protective covers of sufficient strength that do not hinder the operation of working tools that are at risk of touch, such as milling cutters, saw blades, and grinding wheels.

Holes in the power tool housing should prevent accidental access to internal rotating parts and live parts by fingers, etc.

  • Electromagnetic Compatibility

Power tools shouldn’t cause disturbances to radios and TVs when in use. At the same time, power tools should have a good ability to resist electromagnetic disturbances in the electromagnetic environment to ensure that power tools can work normally.

  • Vibration and Noise

Power tools should run smoothly, be easy to operate, and have low noise. When using the power tool, it should not cause noise pollution to the surrounding environment.

  • Light and Compact

In order to reduce labor intensity as much as possible and improve the adaptability to processing objects, power tools should be small in size, light in weight, and easy to operate and control.

  • Sturdy and Durable

Power tools are required to be safe and reliable in use, with high reliability in their insulation structure, mechanical structure, and housing protection, with firm connections and ability to withstand unavoidable impacts and abnormal operations.
