The requirement for smoke detectors to function in smoke conditions is given under which standard?

The requirement for smoke detectors to function properly in smoke conditions is addressed in ANSI/UL 268. This standard specifically outlines the performance requirements for smoke detectors, including how they should operate in the presence of smoke. It establishes criteria for testing the sensitivity of detectors and their response to various types of smoke to ensure they can reliably detect smoldering smoke and provide early warning in a fire situation.

By adhering to ANSI/UL 268, manufacturers ensure their smoke detection devices are reliable and effective, which is vital for the safety of occupants in a building. This standard includes various environmental tests to confirm that smoke detectors can function correctly across different conditions, thereby fulfilling their critical role in fire safety systems.
