What is UL 60335-2-345 ?

Title: Understanding UL 60335-2-345 and UL 60335-2-360: Safeguarding Battery-Operated Products

The use of battery-operated handheld motor-operated and intensified photodiode flashlight products has increased significantly in recent years, driven by their convenience and versatility. However, these products pose potential safety hazards if not designed, manufactured, and used properly. To address these concerns, Underwriters Laboratories (UL) has developed two safety standards: UL 60335-2-345 and UL 60335-2-360. In this article, we will深入探讨这两个标准, 阐述它们对确保电池-operated产品安全的重要性. UL 60335-2-345: Safety Requirements for Battery-Operated Handheld Motor-Operated and Intensified Photodiode Flashlight Products

UL 60335-2-345 is a safety standard developed by UL specifically for the safety requirements of battery-operated handheld motor-operated and intensified photodiode flashlight products. This standard aims to provide guidelines and requirements for ensuring the safe use of these products, which may have various applications in security, law enforcement, outdoor recreation, and emergency situations.

The primary purpose of UL 60335-2-345 is to identify potential risks and hazards associated with these products and establish criteria to mitigate them. The standard covers various aspects, including electrical safety, fire safety, and performance.

Key Requirements of UL 60335-2-345:

Electrical Safety:

a. Appliance must have a List A, which outlines the maximum allowable voltage and current ratings for various components.

b. The appliance must also have a List B, which specifies the minimum allowable resistance values for the appliance's electrical components.

Fire Safety:

a. The appliance must have a fire-resistant casing that meets UL 7104 standards.

b. The appliance's electrical components must be designed to self-extinguish in case of overheating.

Performance:

a. The appliance must have a specified output voltage, current, and flash time.

b. The appliance's performance must meet the requirements specified in UL 60335-2-345.

UL 60335-2-360: Safety Standards for Appliance Using Flammable Refrigerants

UL 60335-2-360 is a set of safety standards developed by UL for appliances using flammable refrigerants. The primary objective of UL 60335-2-360 is to address the unique challenges associated with appliances using flammable refrigerants and ensure their safe operation.

Key Requirements of UL 60335-2-360:

Appliance Design and Construction:

a. The appliance must have a fire-resistant casing that meets UL 7104 standards.

b. The appliance's design must prevent the formation of electrical continuity between different parts of the appliance.

Refrigerant Leakage:

a. The appliance must not leak refrigerant, which could come into contact with an open flame or sparkling water.

b. The appliance must also not release any flammable vapors when in operation.

Operating Temperature:

a. The appliance must be able to operate within the temperature range specified by the manufacturer.

b. The appliance must not exceed the maximum allowable operating temperature for flammable refrigerants.

Conclusion:

UL 60335-2-345 and UL 60335-2-360 are essential safety standards developed by UL to ensure the safe use of battery-operated handheld motor-operated and intensified photodiode flashlight products. By complying with these standards, manufacturers can ensure that their products are safe to operate and pose minimal risk of fire or explosion. As such, it is crucial to follow the guidelines and requirements outlined in these standards to minimize potential hazards associated with these products.
