4. TEST INSTRUCTION

4.1 Microwaves creepage

Specification: the microwaves creepage –a distance of 50mm of the external

surface of the device could not exceed 1miliwatts for squared centimeters.

Experience: a (275 +/-5) g load of potable water at (20 +/-2) ºC temperature

inside a recipient of thin walls of borosilicate glass with diameter upper 85mm

is places at the horizontal support center, the device supplied with nominal

voltage and operated with controls adjusted to maximim power. The

microwaves meter is moved over the device surface with objective the locate

microwaves creepage.

The maximum creepage colud not exceed 1 miliwatts per squared

centimeters.

4.2 Output power measurement of microwaves

It must be utilized borosilicate recipient with external diameter of

aproximately 190mm and height of 90mm and thickness of 3mm.

At the begining of the experience, the oven and the recipient must be at

environment temperature. And used to the experince potable water with 10

+/-1 ºC initial temperature. The water temperature is measured immediately

before to placed in recipient.

An amount of 1000 +/-5g of water is added in recipient. The recipient is

placed at plate center of the oven. The device is supplied with nominal

voltage at the adjustment of maximum power. It must be placed the needed

time for that the water reach 20 +/-2ºC. After the time finishing it leave the

recipient and it measured immediately.

Notas:

üThe water is mixed before your temperature be measured.

üDevice of mixing and measurement must have low capability of heating.

üSpecified power 800 Watts (IEC 705)

üPower tolerance +15-10%

The output power of the microwaves is calculated by formulation:

P = (1/T) x [4,187 x Mw x (T2 –T1) + 0,55 x Mc x (T2–T0)] / T

Where:

P = microwaves output in watts.

Mw = water mass in grammes.

Mc = recipient mass in grammes.

T0 = environment temperature in ºC.

T1 = water initial temperature in ºC.

T2 = water final temperature in ºC.

T= heating time in seconds, excluding the heating time of the magneton

filament.

MSE-301

4.3 Input power

The oven will have to be supplied with nominal voltage and a load of 1 liter of

water.

The measured input power could not present deviation more than 60W in

relation to the specified value, or either, the speficied value for consumed

power will be:

Consumed power = 1340 + 60W.

4.4 Oscillation frequency of the microwaves

The nominal frequency 2450MHz can vary +/-15MHz.

4.5 Creepage current and dielectric hardeness

Inicial experience: Submit a device to a climstic expereince during 72 hours

at the following conditions: 24 hours at the environment temperature and 48

hours a 30 +/-2ºC and 93 +/-2% of relative wetly.

Creepage current

The device creepage current could not exceed 0,5mA for class 01, when

submitted to a 1000V voltage.

4.5.1 Dielectric hardness

It could not occur anything spark ou fail when submitted to sinusoidal voltage

of 60Hz frequency, during 1 minute accordance the following description:

-beetwen the body and the poles of the supply cord, 1250V.

4.6 Heating

The device is placed as if was inlaid under of ceiling as

the following specifications.

a) minimum height in relation to device 150mm

b)depht of the ceiling 300mm, from the wall of the corner of experience.

c) minimum length 150mm more than the device width.

d) the device must be supplied with voltage 1,06 time the nominal voltage.

As the microwaves, the device is operated during 9 consutives periods of 10

minutes separated by an rest period of 1 minute.

It was adopted as load 1000g of water at 20ºC temperature. During the rest

period, the door is opened and replaced in the recipient.

During the heating experience, the temperature addition

could not exceed the specified values in the table A.

2. Next the motor of the revolving. 60

3. Externallateral of the oven beside the transformer.60

4. Externalcentral superior of the oven 60

5. Insulation of white cable next the superior interlock. 65

6. Insulation of the black grey that come from the transformer primary

rolling. 65

4.7 Operation without load

The microwaves oven must be operated without load

during themost time permitted by timer.

The oven could not suffer no damage. Any device of

safety will have to act.

4.8 Supervision device

To curt-circuit the supervisor device of the door. Supply

the device with nominal voltage with the door closed. The

door opening will provoke the automatic power off of the

microwaves generator.

4.9 Protection against electric chock (miniature standard finger)

The standard finger miniature (figure 101 of the IEC 335 -

-25) cannot touch live parts when applied without

appreciable force in device parts that are accessible only

when the oven is operated in normal use.

4.10 Cutting parts

The device will not have present cutting partes that can

bring risk to the user during a normal operation or

maintans.

4.11 Insulation

Do not have be used as insulation the following materials:

üwood, cotton, silk, ,commom paper, with staple, hygroscopic.

MSE-301

4.12 Amianthus

Amianthus cannot be used in construction of devices.

4.13 Internal wiring

4.13.1 Internal wiring guide

The internal wiring guide must be smooth and free of

cutting parts.

The wiring cannot have contact with wings barbs of

cooling or similar.

The metallic orifice must be smooth and corners without

tips except if have bushings.

The wiring must not have contact with mobile parts.

4.14 Internal wiring insulation

The internal wiring insilation must resiste at the voltage

experience applied of 2000V, 60Hz during 15 minutes if

have not marking equivalent to IEC227, IEC245, NBR

13249 and NBR 9374.

4.15 Wire heart identification

The supply cord of class 01 devices must have a wire

heart that connect the earthing terminal of the device to

the earthing terminal of the electric net.
