1.1 This Standard applies to newly produced, direct gas-fired process air heaters of the recirculating or non- recirculating type (see Clause 3, Definitions), hereinafter referred to as heaters, whose primary purpose is to provide process heating to non-occupied spaces within commercial and industrial buildings and may also include operation as a non-recirculating ventilation air heater (see…

1.1 This Standard applies to newly produced, non-recirculating direct gas-fired heating and forced ventilation appliances, hereinafter referred to as heaters, whose purpose is to address building infiltration, replace building air that is exhausted, offset building conduction heat loss and provide outside air ventilation. All air to the heater is ducted directly from outdoors and the products of…

1.1 This Standard covers requirements for external corrosion protection systems on steel non-pressure tanks that are used for the underground storage of flammable liquids and combustible liquids. The requirements are structured as follows: A Section 5, Cathodically Protected Tanks, covers external corrosion protection using sacrificial magnesium and zinc anodes, low profile nylon isolating…

This National Standard of Canada applies to glazing materials that have been subjected to the test methods described herein. Such test methods are intended to demonstrate minimum performance characteristics designed to reduce the likelihood of cutting and piercing injuries resulting when glazing materials used in areas of human impact (see Annex A) in building and architectural applications…

1.1 This standard applies to pin and sleeve type plugs, receptacles, power inlets, and connectors, rated up to 800 amperes and up to 600 volts ac or dc, and which may include up to eight pilot contacts. These devices are intended to provide power from branch circuits, or are for direct connection to the branch circuit in accordance with the Canadian Electrical Code Part I, the National…
