IEC 60335-1 clause 11.2 Black Test Corner For Temperature Rising
Test Corner
Product information:
This test corner conforms to the standard requirement of IEC
60335-1 clause 11.2, IEC60065 clause 7, etc. It is designed and
manufactured to provide the required environment for the
temperature rising test of all kinds of electrical, electrical
products. It can be customized according to the different testing
samples.
The number on every connector socket and the test point number on
the test corner are corresponding.
This test corner adopts K-Thermocouple for measuring.
Technical parameters:
1. Inner size: L*W*H: 1000*1000*1000mm (Side plate*2, base plate*1,
top plate*1)
2. Thermocouple: The diameter of the thermocouple is less than
0.3mm
3. The thermocouple arrangement: Arranged on the side panels and
bottom panel, and all the measuring points will be leaded to one
panel by thermocouple for easy connection with data logger (the
data logger should be prepared by user)
4. The sheet copper used for temperature measurement: the diameter
of 15mm and the thickness of 1mm. 48 pcs of copper sheet for model
SN1102-2.
5.The number of temperature measuring points: 48 points for model
SN1102-2
6.The arrangement of temperature measuring points: 100*100mm,
square stationing.
7.Plywood: The thickness is 20mm and the front side is painted with
Berlin black and the reverse side is with gray film plate.
8. The movable part: there are 4 removable wheels installed on the
bottom of the device.
Sinuo can customize different sizes with different temperature
measuring distribution according to client's specific requirements.
And our test corners are well painted, the themocouples and
measuring coppers are well arrayed, all the themocouples are leaded
to the terminal block, which is covenient for client to connect to
the temperature measuring and recording instruments.
Test Method:
1. Prepare a thermocouple with plugs on the two ends, insert one
plug into the socket of corresponding measuring point (please refer
to the Attachment: Distribution map of measuring points), insert
the other end into the temperature measuring instrument.
2. In order to make the temperature measuring instrument work
stably, the temperature measuring instrument should be powered on
before the normal test, and the measurement should be started after
30 minutes of warm-up.
3. Use a temperature measuring instrument with a resolution of
0.5°C and a range of 50°C to measure the indoor ambient temperature
"T".
4. The specimen is placed at the proper position in the test
corner, and powered on.
5. After the test starts, stay for 3 to 5 minutes and then read out
the indicating value "T1" shown on the temperature measuring
instrument, the actual temperature value of the measuring point.
6. The temperature rise value at a certain point T=T1-T.
