Scope 1.1 General This Standard covers steel valves primarily intended for use in oil or gas pipeline systems. The following types of valves are covered: (a) gate valves; (b) plug valves; (c) ball valves; and (d) check valves. 1.2 Size, nominal pressure class, and category 1.2.1 Size This Standard covers valves in sizes from NPS 2 to NPS 60. (See Table A.1.) 1.2.2 Nominal pressure class This…

Scope 1.1 This Standard applies to non-conductive optical fiber cable and conductive optical fiber cable intended to be installed indoors in non-hazardous locations in accordance with the Canadian Electrical Code, Part I. 1.2 This Standard does not cover hybrid optical fiber cables whose construction (excluding the optical fiber component) is covered in other applicable standards of the…

Scope 1.1 General This Standard describes the apparatus, test methods, and formulas to be used in carrying out the tests and calculations required by CSA electrical wire and cable Standards. 1.2 Acceptance requirements The acceptance requirements expected to be fulfilled through the testing of any particular type of wire or cable are contained in the Standard relating to that type and do not…

Preface This is the harmonized ANCE, CSA, and UL standard for Fire Pump Controllers. It is the first edition of NMX-J-626-ANCE, the first edition of CSA C22.2 No. 263, and the second edition of UL 218. This edition of UL 218 supersedes the previous edition published in 1996. Scope 1.1 Products covered 1.1.1 These requirements cover controllers intended for starting and stopping centrifugal…

Scope 1.1 This Standard applies to motor-operated appliances* intended for use with nominal system voltages of 600 V and less, except that where appliances are driven by universal-type motors or electromagnetic mechanisms, the scope is limited to appliances rated for use on nominal system voltages of 240 V or less. This Standard applies to appliances designed to be used in accordance with…

IEC 62577:2009 applies to a single stand-alone broadcast transmitter operating in the frequency range 30 MHz to 40 GHz when put on the market. The objective of the standard is to specify, for such equipment operating in typical conditions, the method for assessment of compliance distances according to the basic restrictions (directly or indirectly via compliance with reference levels) related to…

IEC 62149-5:2009 specifies performance on the transceiver modules for asynchronous-transfer-mode passive optical network (ATM-PON) systems recommended by the International Telecommunication Union (ITU) in ITU-T Recommendation G.983.1. The main changes with respect to the previous edition are: - Normative references have been updated; - Incorrect "Letter symbols" have been corrected…

IEC 60644:2009 applies primarily to fuse-links used with motors started direct-on-line on alternating current systems of 50 Hz and 60 Hz. Standardizes time-current characteristics to formulate additional pulse withstand requirements regarding testing and to give guidance for the selection of fuse-links to be used with motors. Note: Fuse-links according to this specification should comply with the…

1 Scope 1.1 This Standard provides requirements for the design, fabrication, installation, and maintenance of single-membrane structures that are either reinforced or unreinforced and that are air-supported, frame-supported, or cable-supported. 1.2 The general requirements, structural design methods, loadings, and limit states specified in this Standard are intended to be consistent with the…

1 Scope 1.1 This Standard specifies requirements for single- and multi-conductor insulated cables having metallic interlocked armour without an overall jacket (Type AC90 or ACG90) or with an overall jacket (Type ACWU90 or ACGWU90) that are intended for installation in accordance with the Canadian Electrical Code, Part I, on systems having nominal voltages of 600 V and less. ACG90 and ACGWU90…
