UL 346-2005防火信号系统用水流量指示器

1.1 These requirements cover vane type waterflow indicators intended for use in fire protective signaling systems to be employed in ordinary indoor locations, in accordance with the National Fire Alarm Code, NFPA 72. 1.2 Waterflow indicators covered by these requirements include sizes 3/4 inch and larger. The indicator sizes refer to the nominal inside diameter of the main sprinkler pipe or tubing on which they are installed. 1.3 A vane type waterflow indicator is an assembly of a mechanism having electrical contacts arranged to transmit a coded or noncoded signal when the vane, located in the supply pipe (riser) of a sprinkler system, is moved by the flow of water in the pipe. This flow is normally caused by the opening of one or more sprinkler heads resulting from a fire condition. The signaling contacts are intended to be connected to circuits of private fire protective signaling systems. 1.4 These requirements do not cover pressure-operated waterflow indicators.

UL 2097-2006电子设备用双绝缘系统的参考标准

These requirements cover double insulation systems intended for use in ungrounded electronic equipment marked \"Double Insulation,\" \"Double Insulated,\" or with the double-insulation symbol intended to be employed in accordance with the National Electrical Code, ANSI/NFPA 70. Equipment marked \"Double Insulation,\" \"Double Insulated,\" or with the double-insulation symbol shall comply with the applicable requirements in this standard and in the standard covering the particular type of equipment - the end-product standard. In cases where the end-product standard contains requirements for double insulation, the end-product standard takes precedence. It is intended that the requirements in this standard be applied to end products marked as described unless the end-product standard specifies different requirements. These requirements were developed for categories that do not have double insulation requirements, to provide guidance about double insulation systems, and to promote consistent approaches to double insulation. Double insulation requirements for electronic equipment are applicable to the double insulation systems used in products contained in various end-product, component and systems standards. Guidelines and Applications for Double Insulation Systems for Electronic Equipment in Appendix a covers: a) Level of Protection Provided by Double Insulation, b) Methods to Address Product-Specific Double Insulation Requirements, and c) Guidelines for Including Double Insulation Requirements in an End-Product Standard. 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 to determine that the level of safety as originally anticipated by the intent of this standard is maintained. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard shall not be judged to comply with this standard. Where appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
