What is IEC 60335-2-7 ?

IEC 60335-2-7 is an essential standard for the safety of electrical hand tools. This standard, which is part of the IEC 60335-2 series, outlines the minimum requirements for the design, manufacture, and testing of hand tools. It is widely recognized that the use of electrical hand tools can pose a serious safety risk to users, especially if proper safety measures are not taken.

The scope of IEC 60335-2-7 is to establish a common standard for the safety of electrical hand tools, which can be used for various purposes, such as woodworking, metalworking, and DIY projects. The standard covers various aspects of the hand tools, including electrical characteristics, power supply, and user controls.

Some of the key requirements of IEC 60335-2-7 include the use of insulated handles, which are designed to reduce the risk of electrical shock. The standard also requires the use of risk-free power supplies, which are designed to minimize the risk of electrical fires or other safety hazards. Additionally, the standard calls for the use of user controls, such as circuit breakers or fuses, which can help to prevent electrical accidents.

IEC 60335-2-7 also specifies the testing procedures that must be followed to ensure that electrical hand tools meet the safety requirements established by the standard. This testing includes both laboratory testing and field testing, which are designed to verify that the hand tools are safe to use in a variety of different environments.

It is important to note that IEC 60335-2-7 is just one of several international safety standards that are used to ensure the safety of electrical appliances. It is crucial for manufacturers to carefully design and manufacture their hand tools to meet the safety requirements established by this standard. By doing so, they can help to minimize the risk of electrical accidents and injuries, which can have serious consequences for both consumers and manufacturers.

In conclusion, IEC 60335-2-7 is an essential standard for the safety of electrical hand tools. It is widely recognized that the use of these tools can pose a serious safety risk to users, especially if proper safety measures are not taken. By following the key requirements outlined in this standard, manufacturers can help to minimize the risk of electrical accidents and injuries, which can have serious consequences for both consumers and manufacturers.
