What is the standard IEC 60335-2-89 ?

IEC 60335-2-89 is an essential standard that sets the limit for the charge of electrically-operated hand-held tools, transportable tools, and lawn and garden machinery. It is vital to ensure the safety of consumers by establishing limits on the amount of electrical energy that can be stored in the device.

IEC 60335-2-94, on the other hand, is a technical standard that focuses on the safety requirements for the design and manufacturing of household and similar electrical appliances. It is specifically designed to ensure that electrical appliances used for commercial and industrial purposes are safe to use and do not pose any risks to users or property.

The key requirements of IEC 60335-2-94 are designed to reduce the likelihood of accidents, injuries, and property damage caused by faulty appliances. Manufacturers must ensure that their appliances meet the following requirements:

* Insulation: The appliance must be designed to prevent electrical currents from passing through the body or clothing.

* Electric shock protection: The appliance must have an adequate circuit breaker or other electrical protection to prevent electrical shocks.

* Mechanical strength: The appliance must be capable of withstandting the forces applied to it, including those resulting from normal use and any anticipated forces.

* Temperature limits: The appliance must not exceed the temperature limits specified in the standard.

* Fire hazards: The appliance must not pose any fire hazards, and any electrical components must be designed to prevent the spread of fire.

By adhering to these safety requirements, manufacturers can reduce the likelihood of accidents, injuries, and property damage caused by faulty appliances. It is essential to understand the importance of IEC 60335-2-94 in ensuring the safety of consumers.
