MICROWAVE MEASUREMENT PROCEDURE

After adjustment of the door, interlock and monitor switches are completed individual or collectively, interlock switch test and microwave leakage test must be performed with survey instrument and test results must be confirmed to meet the requirement of the performance standard for microwave ovens as undermentioned.

Requirement

Every microwave oven shall function in such a manner that when the oven is fully assembled and operating with it’s service controls and user controls adjusted to yield the maximum output, the leakage radiation, at all points at least 5 cm. from the external surface of the oven, does not exceed:

1.1.0mW/cm2 with the test load, 275±15ml of water at an initial temperature of 20±5οC.

2.5.0mW/cm2 when the outer enclosure is removed with a

test load of 275±15ml water at an initial temperature of 20±5οC.

3.5.0mW/cm2 without a test load.

Preparation For Testing:

Before beginning the actual measurement of leakage, proceed as follows:

1.Make sure that the actual instrument is operating normally as specified in its instruction booklet.

Note: Survey instruments that comply with the requirement for instrumentation as prescribed by CSA and NHW performance standard for microwave ovens must be used for testing.

Recommended instruments are:

NARDA 8100

NARDA 8200

2.Place the oven tray in the oven cavity.

3.Place the load of 275±15 ml of tap water initially at 20±5οC in the center of the oven cavity.

The water container shall be a low form of 600 ml beaker with an inside diameter of approx. 8.5 cm and made of an electrically nonconductive material such as glass or plastic.

The placing of this standard load in the oven is important not only to protect the oven, but also to insure that any leakage is measured accurately.

4.Close the door and set the time cooking for several minutes. And start the oven. If the water load is depleted replace it.

Leakage test:

Leakage Test with Enclosure Installed.

1.Grasp the probe of the survey instrument and hold it perpendicular to the gap between the door and the body of the oven.

2.Move the probe slowly, not faster than 2.5cm/sec. along the gap, watching for the maximum indication on the meter.

3.Check for leakage at the door screen, sheet metal seams and other accessible positions where the continuity of the metal has been breached (eg., around the switches, indicator, and vents).

4.Measure carefully at the point of highest leakage and make sure that the highest leakage is no greater than 4mW/cm2, and that the primary interlock switch does turn the oven OFF before any door movement.

Leakage Test without Enclosure.

1.Remove the enclosure (cabinet).

2.Grasp the probe of the survey meter and hold it perpendicular to all mechanical and eleeectronic parts of the oven that is accessible to the user of the oven including, but not limited to, the waveguide, cavity, cavity seams, magnetron and magnetron to waveguide connection.

3.Move the probe slowly (not faster than 2.5cm/sec.), watching for the maximum indication on the meter.

4.Measure carefully at the point of highest leakage and make sure that the highest reading is under the required limit as mentioned above.

CAUTION !

Special attention should be given to avoid electrical shock because HIGH VOLTAGE is generated during this test.

No Load Test

1.Operate the oven without a load and mesure the leakage by the same method as the above test procedure “A. Test Enclosure Installed”.

2.Make sure that the highest leakage should not exceed 5mW/cm2.

Note: Do not perform this test for extended periods.
