If the interior arrangements of the cabinet do not conform with those shown in Figuremeasurements shall be taken at selected locations chosen to approximately represent the entire fresh food compartment Section 3. An external door that is hinged on the right-hand side when viewed facing the cabinet.

A freezer which is accessible from the front. Please first verify your email before subscribing to alerts. If the model being tested has a long-time automatic defrost system, the test period may consist of two parts: This standard is also available to be included in Standards Subscriptions. The recorded temperature shall be the average temperature at that point during a cycle Section 3. One that can have its vertical position changed without the use of tools. There shall be no loads in the freezer compartments of automatic defrost freezers, refrigerator-freezers and all-refrigerators.

Defrost water from the fresh food compartment is disposed of automatically or collected in a container for subsequent manual removal.

This standard is not included in any agam. Stabilization is defined as a minimum of three consecutive defrost cycles with times between defrosts that will allow the calculation of a Mean Time Between Defrosts MTBD1 that satisfies the statistical relationship of 90 200 confidence. If the document is revised or amended, you will be notified by email. Ice trays Section 3. The first freezer door-opening shall be simultaneous with the fourth fresh food door-opening.

No part of the dispenser unit shall be included as volume. The third part is the optional test to determine the time between defrosts see Section 5. Except when specified for particular tests, the ambient relative humidity need not be controlled.

Electrical measurements shall be made with the following instruments or their equivalents: Standards Subsctiption may be the perfect solution. Also available online from CSA from www. Perform the optional test for variable defrost control models to find CT. Defrost water is disposed of automatically or collected in a container for subsequent manual removal.

The recorded temperature of the wine storage compartment shall be the average of the temperatures recorded at the three locations shown in Figure The second part of the method shall be conducted separately for each automatic defrost system.

Outer door gaskets shall be checked for adequacy of seal to the cabinet and adjusted, if required.

If the model has the quick freeze option, it shall be used to bypass the temperature control. The first freezer door- opening shall occur at the initiation of the test period.

The defrost heater shall not either function or turn off differently during the energy test than it would when in typical room conditions. Also, the product shall not recover differently during the defrost recovery period than it would in typical room conditions.

The locations selected shall be recorded. The total volume to be deducted shall comprise the following: Temperature measuring devices shall be located or shielded so that indicated temperatures are not affected by the operation of the condensing unit or adjacent units. The purpose of this standard is to establish a uniform and repeatable procedure or standard method for measuring specified product characteristics of household refrigerators, household wine chillers and household freezers.

The test is repeated on at least one more unit of the model and until the Mean Time Between Defrosts for the multiple unit tests MTBD2 satisfies the statistical relationship. For types 5 and 6; the height dimension shall be measured from the bottom of the liner or from the top of a trivet, if furnished. These figures graphically support procedures for determination of volume described in Sections 4. If no “off” cycle occurs during the stabilization period, the test period shall be at least 3 hours.

For refrigerators and refrigerator-freezers: Freezer door shelves shall be loaded with the maximum number of filled packages that can be retained on each shelf without added restraints. A control scheme that changes the defrost interval from a fixed length to an extended length without any intermediate steps is not considered a variable defrost control.

A separate insulating element or integral extension of the cabinet interior surfaces around the periphery of the cabinet door or drawer opening s which functions as a thermal barrier to minimize heat flow to the interior of the cabinet. For cycling units, the test period shall be two or more complete compressor cycles comprising at least 3 hours a compressor cycle is a complete “on” and a complete “off” period of the motor.

Chiller and drip trays and interior of cabinet shall be dried prior to start of test after evaporator has been manually defrosted. Electric heaters that would normally operate at typical room conditions with door openings shall also operate during the energy test.

It bypasses the thermostat control and operates continually until the feature is terminated either manually or automatically. If the compartment temperature s measured during these two tests bound the appropriate standardized temperature sthen these test results shall be used to determine energy consumption for a given setting of the anti-sweat heater switch. For analog measuring instruments the smallest scale division must not exceed 1 V.

An enclosed compartment or container provided primarily to retard the dehydration of fruits and vegetables. If the model being tested has a variable defrost 208 Section 3. Unless otherwise specified, the cabinet shall be installed with all of its sides, except the back, more than 10 inches Record the locations selected. The average per-cycle energy consumption for a cycle type Section 3.
