These requirements cover machines intended for general industrial use, operating from a voltage of 1000 volts or less. This equipment is intended for installation in ordinary locations, in accordance with the National Electrical Code, ANSI/NFPA 70, where the ambient temperature does not exceed 40°C (104°F) maximum.
These requirements also cover the following type of machines, complying with the Electrical Standard for Machinery, NFPA 79; Machine Tools, Plastics Machinery, Wood Machinery, Assembly Machines, Material-Handling Machines, Inspection/Testing Machines, Packaging Machines, Factory Automation Equipment, Pick and Place Machines and Industrial additive Manufacturing Machines.
Equipment intended for use in hazardous locations, as defined in the National Electrical Code, ANSI/NFPA 70, are covered by the Standard for Explosion-Proof and Dust-Ignition-Proof Electrical Equipment for Use in Hazardous (Classified) Locations, UL 1203.
Fire-protective signaling systems are covered by the Standard for Control Units and Accessories for Fire Alarm Systems, UL 864.
A freestanding assembly of circuit breakers and busses for control of electric light and power circuits or equipment intended for field installation in dead-front switchboards are covered by the Standard for Switchboards, UL 891.
Equipment intended to supply automatic illumination, power, or both, to critical areas and equipment essential to safety of human life is covered by the Standard for Emergency Lighting and Power Equipment, UL 924.
Swimming pools and spas are covered by the Standard for Electric Spas, Equipment Assemblies, and Associated Equipment, UL 1563.
Fuel cells, photovoltaic systems, or utility interactive systems are covered by the Standard for Inverters, Converters, Controllers and Interconnection System Equipment for Use With Distributed Energy Resources, UL 1741.
Emergency alarm equipment is covered by the Standard for General-Purpose Signaling Devices and Systems, UL 2017.
Equipment for gas or vapor detection is covered by the Standard for Gas and Vapor Detectors and Sensors, UL 2075.
Communication equipment, such as telephone equipment, intended for installation in accordance with Chapter 8 of the NEC, is evaluated to the Standard for Information Technology Equipment - Safety - Part 1: General Requirements, UL 60950-1.
Physical access control systems, which provide an attended or unattended means of monitoring or controlling traffic through portals of a protected area for security purposes; or in key management systems, which regulate or control access to the use of a device by electrical, electronic or mechanical means, are covered by the Standard for Access Control System Units, UL 294.
Equipment for theft deterrent or warning purposes, such as detectors, security containers or alarms for merchandise or property, are covered by the Standard for Antitheft Alarms and Devices, UL 1037.
Equipment primarily intended to energize or de-energize electrical loads to achieve the desired use of electrical power is covered by the Standard for Energy Management Equipment, UL 916. Such equipment is intended to control electrical loads by responding to sensors or transducers monitoring power consumption, by sequencing, by cycling the loads through the use of preprogrammed data logic circuits, or any combination thereof.
Robotics and associated control equipment is covered by the Standard for Robots and Robotic Equipment, UL 1740.
Consumer 3D Printers are evaluated to the Standard for Information Technology Equipment - Safety - Part 1: General Requirements, UL 60950-1 and the Standard for Audio/Video, Information and Communication Technology Equipment - Part 1: Safety Requirements, UL 62368-1.
