What is UL60335-2-34 standard?

The UL60335-2-34 standard is a technical safety standard developed by Underwriters Laboratories (UL), which focuses on the safety requirements for electrical appliances equipped with rotating discs, such as clothes dryers and washing machines. This standard is widely recognized and used in various industries to ensure the safe operation of these types of appliances in both residential and commercial settings.

Key requirements of the UL60335-2-34 standard

1. Mechanical Strength and Stability: The standard requires that the appliance's structure, components, and enclosure can withstand the mechanical stresses generated during normal operation. This includes resistance to vibration, impact, and forces caused by imbalance or emergency stop situations.

2. Electric Shock Hazards: The standard sets out specific requirements to prevent electric shock risks, including insulation and grounding. It checks for factors like clearance distances, creepage distances, and earthing connections to ensure user safety.

3. Thermal Risks: Appliances covered under this standard need to be designed to manage potential fire hazards and high temperatures effectively. It includes testing against over-heating, flammability, and thermal stability to prevent any possible damages or accidents.

Testing and certification of compliance

To demonstrate compliance with the UL60335-2-34 standard, manufacturers submit their products to accredited testing laboratories. These labs evaluate the appliances based on the standard's requirements through various tests and inspections. When all the safety criteria are met, the product receives the UL mark, indicating that it meets necessary safety standards.

It is crucial for manufacturers to conform to these safety standards not only for legal obligations but also to gain consumer trust. This ensures that consumers can have confidence in the safety and reliability of the electrical appliances they use in their daily lives.
