Central Forced Air Unitary Heat Pumps With or Without Electrical Resistance
Heat
1. Scope
1.1 This Standard applies to stationary, central, forced air unitary heat
pumps* rated at 600 V or less, single or polyphase, with or without electric
resistance heating, designed to be used in accordance with the Rules of the
Canadian Electrical Code, Part I. For purposes of this Standard a heat pump is
considered to be an electrically driven device.
* Fore convenience, the…
Performance standards in building — Contents and presentation
Specifies the basic contents to be included in performance standards for building components and assemblies, and indicates a standard order for their inclusion. Is intended primarily for use by standards committees preparing performance standards for building components and assemblies. Should also be useful for the preparation of other types of documents.
1. Scope
1.1 This Standard covers minimum requirements for construction, sizes, regular grades, specialty panels, manufacturing tolerances and glue bond types for Poplar plywood intended for construction and industrial applications.
1. Scope
1.1* This Standard applies to insulated conductors intended for use as leads
of transformers, motors, ballasts, solenoids, etc, where the baking temperature
of the windings, coils, etc, to which they are attached will not exceed 150°C,
except for the Type CL 1250 series where the maximum baking temperature will
not exceed 160°C, for Types CL1502 and CL 1503 where the maximum…
1. Scope
1.1 This Standard applies to stationary, electrically heated, warm air,
central furnaces of the forced-air type that discharge air into ducts extending
not less than 30 inches downstream from the heater elements, for use on nominal
system voltages of 600 V and less, designed to be used in non-hazardous
locations in household, commercial, and industrial applications, in accordance…
