Which standard is used for testing electric coin-operated clothes dryers?

The standard used for testing electric coin-operated clothes dryers is UL 2158. This standard specifically addresses the requirements and safety performance for electric clothes dryers, including those that are coin-operated. It sets forth criteria related to the design, construction, and performance of these appliances to ensure that they operate safely and efficiently in a commercial setting.

UL 2158 evaluates aspects such as electrical safety, mechanical safety, and the effectiveness of protective devices, which are essential for preventing hazards during use. This makes it a critical standard for manufacturers of coin-operated washing and drying equipment, ensuring they meet regulatory requirements and provide safe devices for consumers.

Other choices referenced are related to different types of equipment: UL 1077 covers supplementary protectors, UL 1492 pertains to household and commercial appliances not specifically tied to coin operation, and UL 60335 is focused on safety of household and similar electrical appliances, which does not directly apply to coin-operated dryers. Thus, UL 2158 is the correct and relevant standard for testing electric coin-operated clothes dryers.
