What is UL603352343?

UL60335-2-34 is an international safety standard that specifically covers the safety requirements for electric motor-driven vacuum cleaners, as well as dust extractors and wet pickup cleaners. Developed by Underwriters Laboratories (UL), this standard aims to ensure that these appliances are safe to use and do not pose any risk of electrical shock or fire hazards.

The Scope of UL603352343

The UL60335-2-34 standard applies to household and similar electrical appliances with a rated voltage not exceeding 250V. It covers various aspects of safety, including protection against electric shock, fire risks, mechanical hazards, and abnormal operation conditions. Additionally, the standard provides guidelines for the manufacturers regarding construction, connection, and operation of these appliances.

Key Requirements of UL603352343

One of the key requirements of UL60335-2-34 is the insulation integrity of the motor windings to prevent electrical shock hazards. The standard also requires proper grounding and protection against overcurrent, overtemperature, and overloading. Furthermore, it specifies the use of flame-resistant materials in the construction of these appliances to reduce fire risks.

In terms of mechanical hazards, the standard mandates that vacuum cleaners must have mechanisms in place to prevent access to moving parts during operation. It also addresses noise emissions and sets limits to ensure that these appliances do not exceed certain decibel levels that could harm users' hearing.

Compliance and Certification

Manufacturers of electric motor-driven vacuum cleaners must ensure that their products comply with the UL60335-2-34 standard before they can be sold in markets requiring such certification. Compliance testing involves rigorous assessments carried out by accredited testing laboratories to evaluate whether the appliances meet the safety requirements outlined by the standard. Once certified, manufacturers can affix the UL mark to their products, indicating that they have undergone and successfully passed the necessary safety assessments.

In conclusion, UL603352343 is an important safety standard that sets forth the requirements for electric motor-driven vacuum cleaners, ensuring that these appliances are manufactured and designed with user safety in mind. Compliance with this standard guarantees that such appliances meet the necessary safety standards, mitigating risks of electrical shock, fire hazards, and mechanical injury for users.
