This National Standard of Canada is equivalent to International Standard ISO 14269-4:1997. 1 Scope This part of ISO 14269 specifies a uniform test method for determining performance levels of operator enclosure panel-type air filters. It is applicable to tractors and self-propelled machines for agriculture and forestry when equipped with an operator enclosure with a ventilation system.

1.1 Scope 1.1.1 This Standard applies to luminaires for use in nonhazardous locations that are intended for installation on branch circuits of 600 V nominal or less between conductors in accordance with the Canadian Electrical Code, Part I (CE Code, Part I), and the ANSI/NFPA 70 National Electrical Code (NEC). 1.1.2 This Standard does not apply to luminaires covered by other standards…

1. Scope 1.1 This Standard specifies the test methods to be used in measuring the energy efficiency of three-phase induction motors, in support of a consumer/user information program. The method of determining and marking the nominal efficiency values is also specified. Note: The test methods contained in this Standard are not limited to specific types of motors, but where this…

1. Scope 1.1 This Standard provides requirements for thermostat models intended to be used for line-voltage (120-240 V) switching of a controlled resistive heating load that may include a fan, if so specified or provided for by the thermostat manufacturer. It includes single- and double-pole thermostats controlling their load either by fast or slow ON/OFF switching. These models may be…

This International Standard specifies the logical specifications of STbus which is a high-performance and highly reliable system bus. STbus adopts a synchronous transfer method with a high-speed clock and a split transfer method enabling to minimize bus holding time during one bus operation and to use a bus efficiently. This International Standard is applicable to a high-performance system bus or…

This International Standard specifies the characteristics of a 130 mm optical disk cartridge (ODC) of Type WORM (Write Once Read Many) with a capacity of 5,2 Gbytes. Type WORM ODCs use writing effects that are inherently irreversible. Written marks cannot be erased and attempted modification of the written marks are detectable. This International Standard specifies _ the conditions for…
