IEC 61970-301:2013 defines the Common Information Model (CIM), that is an abstract model representing all the major objects in an electric utility enterprise typically involved in utility operations. By providing a standard way of representing power system resources as object classes and attributes, along with their relationships, the CIM facilitates the integration of Energy Management System (…

ISO/PAS 12835:2013 is intended for assessment of casing connections for those field applications in which the design of the casing-connection system is strain-based, and in which primary axial loading is on the casing-connection system driven by constrained thermal expansion, and in which that primary loading exceeds the casing-connection system's yield envelope. Consequently, ISO/PAS 12835:…

IEC 62586-1:2013 specifies product and performance requirements for instruments whose functions include measuring, recording and possibly monitoring power quality parameters in power supply systems, and whose measuring methods (class A or class S) are defined in IEC 61000-4-30. These requirements are applicable in single, dual- (split phase) and 3-phase a.c. power supply systems at 50 Hz or 60 Hz…

ISO 10462:2013 specifies requirements for the periodic inspection of acetylene cylinders as required for the transport of dangerous goods and for maintenance in connection with periodic inspection. It applies to acetylene cylinders with and without solvent and with a maximum nominal water capacity of 150 l.

ISO 13399-50:2013 specifies a reference dictionary for reference systems for cutting tools, together with their descriptive properties and domains of values. ISO 13399-50:2013 specifies a reference dictionary containing: definitions and identifications of the classes of reference systems for cutting tools, with an associated classification scheme; definitions and identifications of the data…

Scope 1.1 This Standard applies to clock-operated switches, rated 600 V or less, designed to be used in ordinary locations to close and open circuits to a load at predetermined intervals, and intended to be employed in accordance with the Rules of the Canadian Electrical Code, Part I. The clock-operated switches discussed in this Standard may be a) completely enclosed, plug-in, or cord-…

Preface This is the eleventh edition of CSA B52, Mechanical refrigeration code. It supersedes the previous editions published in 2005, 1999, 1995, 1992, 1991, 1983, 1977, 1965, 1951, and 1939. The 11th edition of this Standard provides the minimum requirements for the design, construction, installation, inspection, and maintenance of the mechanical refrigeration systems, and is complemented…

Scope 1.1 This Standard applies to encapsulated isolating transformers for use as a circuit continuity device, intended to be installed in airport field lighting series circuits for use in nonhazardous locations in accordance with the Canadian Electrical Code, Part I. 1.2 This Standard applies to transformers that consist of primary and secondary coils that are wound upon a core, the…

Scope 1.1 This Standard applies to filters intended for suppressing electromagnetic interference in, or with, apparatus and machines that are to be connected to an ac supply with nominal system voltages of up to 750V and a nominal frequency of up to 60 Hz or connected to a dc supply up to 1060 V dc, intended to be used in nonhazardous locations in accordance with the Canadian Electrical Code, (…

1 SCOPE 1.1 This Standard contains requirements for 65 mm forged quick connect couplings and adapters of the external lug design for use in the forestry service. NOTE: Quick connect coupling and adapter sizes stated refer to the nominal diameter of the forestry hose. 1.2 The couplings and adapters are intended for use with forestry fire hose of the 65 mm standard sizes.
