Conducting EN 60335-2-31 Testing
EN 60335-2-31 testing involves a series of tests to evaluate the safety and performance of coffee makers. The following steps are involved in conducting this testing:
1. Sample Preparation: Coffee maker samples are prepared for testing by simulating user conditions, such as water flow, temperature, and pressure.
2. Testing Equipment and Instruments: Specialized equipment is used to conduct the tests, including high-voltage testers, thermocouples, and cameras.
3. Testing Environment Requirements: The testing environment must meet specific requirements, including:
Temperature: 18C 5C
Humidity: 40 RH 10
Ventilation: adequate ventilation to prevent overheating
4. Test Procedures:
a. Electrical Insulation Resistance (EIR) test: Measures the resistance between live parts and earth.
b. Dielectric Strength (DS) test: Evaluates the electrical insulation of the coffee makers components.
c. Temperature Rise (TR) test: Assesses the thermal performance of the coffee maker under normal operating conditions.
d. Earth Continuity (EC) test: Verifies the continuity of the earth connection to prevent electrical shock.
