3.2.2 Electrical Measurements
Electrical measurements shall be made with the following, or equivalent, instruments:
(a) Watt-hour meter一the watt-hour meter for measuring electrical energy consumption shall have a resolution equal to or less than 1 and a maximum error no greater than 1 . 5% of the measured value for any demand greater than 100 W.
(b) Voltmeters 一voltmeters shall be accurate to within±0.5% of the quantity measured.
3.3.3 Initial Temperature
The initial temperature of the test block shall be within±2 °C of the ambient room temperature. Prior to the test and during the test, the temperature of the test block shall be measured with a thermocouple and a suitable temperature-indicating or -recording instrument.
3.3.4 Thermocouple Installation
The thermocouple shall be installed so that the thermocouple junction is at the bottom of the hole provided in the test block and so that it makes good thermal contact with the test block. If the test block is to be water-cooled between tests, the thermocouple hole shall be sealed, or other steps shall be taken to ensure that the thermocouple hole is completely dry at the start of the next test. A temperature-indicating system shall be provided for measuring the test block temperature with an accuracy as specified in Clause 3.2.1.
3.5.1 Installation
A free-standing range shall be installed with its back against a vertical wall allowing clearance for the wiring connections. The wall shall extend at least 300 mm above and on either side of the range. There shall be no side walls.
A built-in range shall be installed in an enclosure in accordance with the manufacturer's instructions.
3.5.2 Assembly
Ranges shall be assembled completely with the handles, knobs, guards, etc., mounted in place. Any heating elements, baking racks, and baffles shall be in place in accordance with the manufacturer's instructions. Broiler pans shall be removed from the oven.
If multiple racks are supplied with the oven, only one rack shall be used in the oven to support the test block.
3.6.2 Noncycling Thermostat
If the oven thermostat does not cycle on and off, adjust it to, or determine, an oven thermostat setting that will provide an average oven temperature 180±3 °C higher than the room ambient air temperature. Remove the thermocouple after the thermostat has been set.
3.6.3 Cycling Thermostat
If the oven thermostat operates by cycling on and off, adjust it to, or determine, an oven thermostat setting that will provide an average oven temperature 180±3 °C higher than the room ambient air temperature. Determine the average oven internal temperature by measuring the maximum and minimum temperatures in any three consecutive heating cycles of the oven heating elements, excluding the initial cut-off/cut-on action by the thermostat after the temperature rise of 180±3 °C has been attained by the oven. Remove the thermocouple after the thermostat has been set.CAN CSA C358-03 pdf download.
