What is IEC 60335-2-24:2010 + A1:2012 + A2:2017?

IEC 60335-2-24 is an international standard for the safety of electrical appliances. It provides guidelines and requirements for the testing of appliances such as washing machines, dishwashers, and dryers.

Scope and Application

This standard applies to household and similar electrical appliances that use water as a medium for cleaning or treating clothes, fabrics, or other textile products. It covers both commercial and industrial appliances that fall within this category.

Appliances like washing machines and dishwashers often involve water and potentially hazardous substances. Therefore, it is crucial to have a set of regulations and safety measures in place to ensure the safe operation and minimize the risk of harm to users.

Main Requirements and Testing Procedures

The standard outlines various requirements and testing procedures that appliances must meet to comply with safety standards. These include:

- Protection against electric shock: All accessible parts of the appliance that carry voltage should be adequately insulated to prevent the user from coming into contact with electric current.

- Mechanical strength and stability: The appliances should be designed and built to withstand mechanical stress, ensuring they remain stable during operation and do not pose any risk of injury due to toppling or falling.

- Temperature rise: The standard defines limits for temperature rise in different components of the appliance, such as motors, heating elements, and control devices, to avoid overheating and potential hazards.

- Insulation resistance and dielectric strength: Appliances undergo tests to measure insulation resistance, which indicates the integrity of insulation materials and electrical circuits. Dielectric strength tests help determine if the insulation can withstand high voltage without breakdown.

Conclusion

IEC 60335-2-24 is a crucial standard in ensuring the safety of appliances that use water for cleaning or treating textiles. By complying with the requirements and testing procedures outlined in this standard, manufacturers can provide consumers with safe and reliable products, minimizing the risk of electrical accidents, mechanical failures, and other potential hazards.

It is essential for manufacturers, regulators, and consumers to be aware of the guidelines set forth in IEC 60335-2-24 to ensure the safe usage of such appliances in daily life.
