IEC 60456 Clothes Washing Machines Appliance Performance Test Lab With 12 Test Stations
Standard:
IEC 60456 Clothes washing machines for household use - Methods for measuring the performance;
GBT 4288 Household and similar electrical washing machine.
Application:
This Performance Test Lab is used for measuring the performance of clothes washing machines for household use.
Feature:
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.
System Components:
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
| NO. | Item | Functional Use | Remarks |
| 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 |
