22.4 If a malfunction or breakdown of an electronic component, located in any circuit of the product, results in increased risk of injury to persons, such as a loss of OFF control or unexpected operation, that circuitry shall comply with the requirements in the Standard for Tests for Safety-Related Controls Employing Solid-State Devices, UL 991. A single malfunction is to be considered at a time.
