UL 399-2008飲用水冷卻器

1.1 These requirements cover self-contained drinking-water coolers which employ hermetic refrigerantmotor-compressors and which are designed for connection to alternating-current circuits rated not greaterthan 600 volts in accordance with the National Electrical Code, NFPA 70. The requirements also apply towater coolers which supply both hot and cold water.1.2 These requirements do not include additional requirements applicable to equipment designed for usein hazardous locations as defined in the National Electrical Code, NFPA 70.1.3 A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this standard, and that involves a risk of fire, electric shock, orinjury to persons shall be evaluated using the appropriate additional component and end-productrequirements as determined necessary to maintain the acceptable level of safety as originally anticipatedby the intent of this standard. A product whose features, characteristics, components, materials, orsystems conflict with specific requirements or provisions of this standard cannot be judged to comply withthis standard. Where considered appropriate, revision of requirements shall be proposed and adopted inconformance with the methods employed for development, revision, and implementation of this standard.

UL 935-2001熒光燈鎮流器

1.1 These requirements cover ballasts of the resistance, reactance, and electronic (high frequency) types for use with fluorescent lamps involving a potential of 2500 volts or less in accordance with the National Electrical Code, ANSI/NFPA 70.1.2 A fluorescent-lamp ballast may be determined by investigation to be acceptable for use, in a fixtureor other device, with electric-discharge lamps of other than the fluorescent type.1.3 Fluorescent self ballasted lamps and ballast adaptors are evaluated using the Standard forSelf-Ballasted Lamps and Lamp Adapters, UL 1993. The component ballast is evaluated to requirementsin this Standard.1.4 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 or of electric shockor injury to persons shall be evaluated using appropriate additional component and end-productrequirements to maintain the 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 does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.

UL 1740-2007機器人和自動設備

These requirements cover robots and robotic equipment rated 600 V or less and intended for installation in accordance with the National Electrical Code, ANSI/NFPA 70. Since end-use installation of a robot and robotic equipment may vary for each user application, guidelines for end-product installation may be evaluated to the applicable sections of ANSI/RIA R15.06, Standard for Industrial Robots and Robot Systems-Safety Requirements. Portions of the requirements in this Standard have been excerpted from the Robotic Industries Associations (RIA) Standard for Industrial Robots and Robot Systems - Safety Requirements, ANSI/RIA R15.06. These requirements cover robotic equipment and systems intended for indoor and outdoor use in applications such as parts assembly, parts transfer, automated material handling, inspection, loading, diecasting, deburring, welding, paint spraying, clinical/diagnostic systems, pharmaceutical applications, commercial food processing, automated vehicle refueling systems, library book handling/sorting, clean room applications, medical use for surgery, mobile robots, automated guided vehicles, automated storage/retrieval systems, and the like. Unique features or functions associated with the robotic application, not specifically addressed in this Standard, shall also be evaluated to other applicable Standards/requirements. These may include, but are not limited to, Electrical Equipment for Laboratory Use; Part 1: General Requirements, UL 3101-1; Medical and Dental Equipment, UL 544; Power Operated Pumps for Petroleum Product Dispensing Systems, UL 79. In addition to the requirements in this Standard, robots and robotic systems shall also comply with the applicable sections of the Electrical Standard for Industrial Machinery, ANSI/NFPA 79. Robots and robotic systems intended for use in hazardous locations, as defined by the National Electrical Code ANSI/NFPA 70, shall also comply with the requirements in Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division 1, Hazardous (Classified) Locations, UL 913. In the following text, a requirement that applies to one type of equipment, such as a controller or teach pendant, will be identified by a specific reference. In the absence of a specific reference or if the term robot or robotic equipment is employed, it is to be understood that the requirement applies to all types of equipment covered by this Standard.

UL 1776-2002高壓清洗機
