Description / Abstract: These requirements cover products that are intended for use in printing establishments. Included are such products as sheet–fed, web–fed, and offset presses and controls, composing and typesetting machines, cutting and folding machines, and other products that are used in the preparation of mats. The products covered are for connection to interior wiring systems in accordance with the National Electrical Code, and are rated at 600 V or less.

These requirements do not cover white printers, photocopy machines, typewriters, or any other product that is covered by individual requirements that are separate from this Standard.

Products that generally would be covered by the requirements in this Standard, such as duplicating equipment, are covered by the requirements in the Standard for Information Technology Equipment Safety – Part 1: General Requirements, UL 60950-1, when the product is not intended for use in printing establishments.

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 as determined necessary to maintain the acceptable level of safety as originally anticipated by the intent of this Standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this Standard, cannot be judged to comply with this Standard. Where considered appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this Standard.
