What is UL 1520?

UL 1520 is a technical standard that sets requirements for the safety testing and certification of personal care appliances, such as hair dryers, curling irons, electric shavers, and similar devices. This standard is developed by Underwriters Laboratories (UL), a global safety certification company.

Background and Purpose

The development of UL 1520 was driven by the need to ensure the safety of consumers using personal care appliances. These devices often involve the use of electricity, heat, and moving parts, making it essential to establish safety guidelines and performance requirements.

The purpose of UL 1520 is to evaluate the design, construction, and operation of personal care appliances to minimize the risk of fire, electric shock, mechanical hazards, and other potential dangers associated with their use. By complying with this standard, manufacturers can gain confidence in the safety of their products and provide assurance to consumers.

Key Requirements

UL 1520 outlines various requirements that personal care appliances must meet to obtain certification. These requirements address different aspects of product safety, including electrical insulation, cord durability, temperature control, motor protection, and more.

For example, the standard specifies that the appliance's construction should prevent accidental access to live internal parts to minimize the risk of electric shock. It also sets requirements for proper grounding, ensuring that any electrical faults are safely redirected to ground.

Additionally, UL 1520 states criteria for measuring the surface temperature of hair straighteners, curling irons, and similar devices to avoid burns or other injuries. The standard establishes appropriate limits to prevent excessive heat generation and sets specific test methods to assess the thermal performance of these appliances.

Certification Process

To obtain UL 1520 certification, manufacturers need to submit their products for testing by an accredited testing laboratory. These tests are conducted based on the standard's requirements and cover various aspects of safety and performance.

If a product passes all necessary tests, it receives UL certification, which can be displayed on the appliance or its packaging. This certification mark indicates that the device has been thoroughly evaluated and found to meet the stringent safety requirements defined by UL 1520.

It is important to note that UL 1520 certification is not a one-time process. Manufacturers must commit to regular inspections and periodic retesting to maintain compliance with the standard and ensure ongoing product safety.
