UL Standard for Safety for Outlet Circuit Testers and Similar Indicating Devices,

UL 1436

Scope

These requirements apply to outlet circuit testers, ground-fault circuit-interrupter testers, and similar indicating devices that are

For use on 15- and 20-A, 3-wire, 125-V receptacles,

Intended to be connected to the receptacle for a period of time only as long as is necessary to note the indicated pattern of lights or other similar indicating means, and

Not intended to be a comprehensive instrument or to determine the quality of the grounding circuit.

These requirements also apply to retention testers and other indicating devices with a retention testing capability (hereafter referred to as retention testers) that are intended to indicate the force exerted on the blade or blades of the tester by the contacts of a receptacle.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this Standard, and that involves a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements to determine that the level of safety as originally anticipated by the intent of this Standard is maintained. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this Standard shall not be judged to comply with this Standard. Where appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this Standard.
