IEC 60456 Clothes Washing Machines Appliance Performance Test Lab
With 12 Test Stations
IEC 60456 Clothes washing machines for household use - Methods for
measuring the performance;
GBT 4288 Household and similar electrical washing machine.
This Performance Test Lab is used for measuring the performance of clothes washing machines
for household use.
1. The ambient temperature of the test room shall be maintained at
(23 ± 2) °C throughout the washing machine test. The measured
ambient temperature for washing machine testing shall be reported,
it shall be rounded to the nearest 0.5 °C.
2. The static (gauge) pressure of the laboratory supply water at
the inlet to each test washing machine shall be maintained at (240
± 50) kPa throughout the test, including during filling operations.
3. The temperature of the laboratory supply water to each test
washing machine shall be measured and recorded to the nearest 0,1
°C. It shall be:
– for cold water (1 5 ± 2) °C for all reference programmes except
Cotton 20 °C;
– for cold water (20 ± 2) °C is the recommended option when using
the Cotton 20ºC reference programme. This is recommended for test
washing machine programmes with no internal heating and cold fill
only (cold water wash).
The cold water supply temperature to the reference machine in this
case may be the same as the test washing machine or it may be 1 5
ºC as specified above.
– for hot water the temperature indicated by the manufacturer ± 2
K, or (60 ± 2) °C, if no value is given.
4. The supply voltage to each test washing machine shall be
maintained at the rated voltage±2 % throughout the test. If a
voltage range is indicated, then the supply voltage shall be the
nominal voltage of the country in which the appliance is intended
to be used.
5. The supply frequency to each test washing machine shall be
maintained at the rated frequency ±1 % throughout the test. If a
frequency range is indicated, the test frequency shall be the
nominal frequency of the country in which the machine is intended
to be used.
The washing machine performance test system consists of constant
temperature chamber, cold water supply tank, hot water supply tank,
test station and control and data acquisition system. Its use is as
follows: Appliance Performance Test Lab
|1||Constant Temperature Chamber||Control the temperature in the test chamber so that the test is
performed within the environment required by the standard.||1SET|
|2||Cold Water Supply Tank||Supply test water below the ambient temperature.||2PCS Alternate water supplies|
|3||Hot Water Supply Tank||Supply test water above water temperature below ambient
temperature.||2PCS Alternate water supplies|
|4||Test Station||It is the connection port for sample testing. It has test power
interface, water inlet and outlet interface, thermocouple
interface, water pressure, flow and power meter. It can perform
voltage regulation, power supply selection, water source selection
and various electrical connection tests.||12|
|5||Control and Data Acquisition System||Set test parameters, perform test operations, test data collection,
data collation, report generation, and historical data query.||SET|
