The term that best describes equipment that has undergone testing and is certified to meet specific standards is "labeled." This designation indicates that the equipment has been assessed by a recognized testing organization and has met the necessary safety and performance standards. When equipment is labeled, it typically carries a mark or certification from a safety or testing agency, signifying that it has passed rigorous testing and is safe for use according to established guidelines.

Labeled equipment provides consumers and professionals with assurance regarding its safety and reliability, which is crucial in fields such as electrical work, where adherence to standards is vital for preventing hazards. A label often includes information about the standards the product meets, which helps users make informed decisions about the equipment they choose to use.
