This Technical Information Paper (TIP) contains information or stock preparation pilot plant facilities which can be
used for contract, cooperative, internal and/or customer research and stock preparation produce development
throughout the world. The tables included describe the equipment available at each facility. The user should contact
the site for detailed information on the equipment and support facilities.

Modeling lets designers predict the performance of water distribution systems to solve a wide variety of design, operational, and water quality problems. Manual M32 provides distribution engineers and operators with information on developing and using computer hydraulic models of water distribution systems. Chapters take the reader from basics through data collection, model design, calibration, and applications. The third edition provides new information on hydraulic calibration, transient analysis, and modeling storage tank mixing and water age.

IEC 60364-7-709:2007+A1:2012 applies only to circuits intended to supply pleasure craft or houseboats in marinas and similar locations. The particular requirements do not apply to the supply of house boats if they are directly supplied from the public network. The particular requirements do not apply to the internal electrical installations of pleasure craft or house boats. For the remainder of the electrical installation of marinas and similar locations the general requirements of IEC 60364 together with the relevant particular requirements of IEC 60364-7 apply. This second edition of IEC 60364-7-709 cancels and replaces the first edition, published in 1994. It constitutes a technical revision. The major changes with regard to the previous edition concern are the removal of the requirements for the electrical installation in pleasure craft (these are now covered by IEC 60092-507) and the alignment of the requirements with those in other parts of IEC 60364. This consolidated version consists of the second edition (2007) and its amendment 1 (2012). Therefore, no need to order amendment in addition to this publication.

This Practice describes the requirements for design, construction, and testing for IEEE 841 or severe duty motors. The motors are premium-efficiency, totally enclosed, fan-cooled (TEFC) or non-ventilated (TENV), single-speed, horizontal or vertical, polyphase squirrel cage induction motors that are 600 volts and below.

This Standard Practice covers design requirements, test performance, marking requirements, and nomenclature for butterfly valves designed for high pressure performance, having a seat plane offset from the plane of the stem centerline.

Required ratings, construction requirements, design test requirements, applications, and suggested practices for all high-voltage enclosed indoor and outdoor and nonenclosed indoor and outdoor switches rated above 1000 V are specified. This includes ratings and requirements for such switches as disconnecting, selector, horn-gap, and grounding for manual and power operation, except for interrupter switches, distribution-enclosed single-pole air switches, and distribution cutouts fitted with disconnecting blades.

ULC Standards is pleased to announce the release of the Second Amendment to the First Edition of CAN/ULC-S566-05, Halocarbon Clean Agent Fire Extinguishers. This is a ULC/UL Harmonized Binational Standard and the requirements contained in CAN/ULC-S566-05, including Amendment 2, are identical to the Second Edition of ANSI/UL 2129, including revisions. The Second Amendment of this Standard has been approved by the ULC Committee on Portable Fire Extinguishers, and has been published with the date of March 30th, 2012.

CAN/ULC-S566-05, including Amendment 2, will be of interest to anyone who manufactures, distributes, uses, regulates or inspects fire extinguishers. These requirements cover the construction and performance, exclusive of performance during fire tests, of portable halocarbon clean agent fire extinguishers. Halocarbon clean agent fire extinguishers are intended to be utilized in accordance with the Standard for Portable Fire Extinguishers, NFPA 10 and the National Fire Code of Canada. The requirements for performance during fire testing of halocarbon clean agent fire extinguishers are specified in the Binational Standard for Rating and Fire Testing of Fire Extinguishers, ANSI/UL 711 CAN/ULC-S508.

Amendment 2 to this Standard includes revisions to clarify cylinder requirements with TDGR (Transportation of Dangerous Goods Regulations) and DOT (Department of Transportation) specifications.
