1 Scope 1.1 This Standard specifies the technical requirements for the interconnection of distributed resources (DR) and distribution systems up to 50 kV line to line. This Standard covers all distributed resource technologies with an aggregate capacity of 10 MW or less at the point of common coupling (PCC). 1.2 This Standard does not define the maximum DR capacity or the upper voltage…

1 Scope 1.1 This Standard applies to helmets intended to provide head injury risk reduction for recreational alpine skiers and snowboarders. These helmets can also be worn for other non-motorized recreational snow sport activities. This Standard defines the areas of the head that are to be protected for impact injuries. It covers the basic performance requirements for shock absorption, helmet…

ISO/TR 21707:2008 specifies a set of standard terminology for defining the quality of data being exchanged between data suppliers and data consumers in the ITS domain. This applies to Traffic and Travel Information Services and Traffic Management and Control Systems, specifically where open interfaces exist between systems. It may of course be applicable for other types of interfaces, including…

Scope 1.1 This Standard provides requirements for in-service examinations and positive pressure leakage-rate testing of concrete containment structures of a containment system that are designated as class containment components. 1.2 Periodic testing and inspection of other components and appurtenances of the containment system designed in accordance with the CSA N285 series of Standards are…

1 PURPOSE AND SCOPE This standard specifies the test method used to determine the coefficient of permeability of a soil at the end of a drill casing driven in by ramming. NOTES - 1 This test method is particularly adapted for soils with coefficient of permeability greater than 10- 6 m/s.. 2 The coefficient of permeability or hydraulic conductivity, in metres per second (m/s), is expressed by the…

1 PURPOSE This standard specifies the test method used to determine the coefficient of permeability of a soil around a cavity, named lantern, opened under the end of a drill casing driven by ramming. NOTES - 1 This test method is particularly adapted for soils with coefficient of permeability greater than 10- 7 m/s. 2 The coefficient of permeability or hydraulic conductivity, in metres per…

ISO 7743:2008 specifies methods for the determination of the compression stress-strain properties of vulcanized or thermoplastic rubber using a standard test piece, a product or a part of a product. Three methods are given: using a standard test piece with the metal plates lubricated; using a standard test piece with the metal plates bonded to the test piece; using a product or a part of a…

1 Scope 1.1 This Standard specifies requirements for three-phase live-front pad-mounted distribution transformer units that (a) consist of a transformer and a separable or integral cable entrance compartment; (b) are rated 75 to 3000 kV-A and intended for operation on three-phase underground distribution systems having the preferred rated voltages specified in Tables 1 and 2; and (c) are…

1 Scope 1.1 This Standard applies to compact and household refrigerators, refrigerator-freezers, freezers, wine chillers, and hybrid wine chillers that are electrically operated on a 60 Hz alternating current, with a nominal supply voltage of 115 V. 1.2 This Standard applies to (a) refrigerators and refrigerator-freezers with a maximum capacity of 1100 L (39 ft3); (b) freezers with a maximum…

1 Scope 1.1 This Standard applies to manufactured and modular homes designed to be supported on longitudinal floor beams. Note: For simplicity, the term "manufactured home" is used in this Standard to refer to both manufactured homes and modular homes. 1.2 This Standard includes requirements for the following aspects of manufactured home installation: (a) site preparation; (b)…
