What is UL Standard 1480?

UL Standard 1480 is a technical standard developed by Underwriters Laboratories (UL) that specifies the requirements for the performance and safety of loudspeakers for commercial use. This standard ensures that the loudspeakers meet specific criteria in terms of electrical, mechanical, and environmental characteristics.

Electrical Characteristics

The first set of requirements outlined in UL Standard 1480 pertains to the electrical characteristics of the loudspeakers. These include parameters such as power handling capacity, impedance, frequency response, and distortion levels. The standard specifies the tests that need to be conducted to measure these characteristics and sets limits within which the loudspeakers must perform to achieve compliance.

Mechanical Characteristics

In addition to electrical characteristics, UL Standard 1480 also addresses mechanical aspects of loudspeaker design. This includes requirements for structural integrity, durability, and mounting options. The standard ensures that the speakers are built to withstand physical stresses such as vibration, impact, and environmental conditions. It outlines the tests that need to be conducted to evaluate these mechanical characteristics.

Environmental Characteristics

Lastly, UL Standard 1480 defines the environmental characteristics that loudspeakers must meet. These include requirements related to temperature range, humidity resistance, and exposure to various chemicals. The standard ensures that the speakers can function reliably in different settings, including indoor and outdoor environments. It provides guidelines for testing the speakers under different environmental conditions to verify their performance and safety.
