The microwave ovens used in residents' daily lives must comply with the relevant effective standards in the testing standards G B4706-2008 "Safety of household and similar electrical appliances - Special safety of microwave ovens, including combination type microwave ovens" and G B4706-2005 "Safety of household and similar electrical appliances - Part 1: General requirements", as well as G B24849-2010 "Energy efficiency limits and levels for household and similar microwave ovens"
2. Testing Content
When testing a microwave oven, the main aspects involved include: anti electric shock protection, power, temperature rise, electrical strength leakage current, and other related items.
. At the same time, check the energy efficiency values in the above aspects, as well as the energy consumption in standby, shutdown, and barbecue states3. Testing Environment
When conducting safety monitoring work, it is necessary to place household electrical equipment in an environment with a temperature between 20 and 25 degrees Celsius and no strong convective air. There are no obvious requirements for humidity and air pressure in this process When monitoring the energy efficiency of electrical appliances, it is necessary to place them indoors at 20-25 degrees Celsius without obvious convective gases, and keep the humidity around 46% -74%
4. Testing Equipment
When monitoring household appliances, commonly used equipment includes: power supply, electrical parameter meter, temperature recorder, thermocouple electronic scale, etc When conducting safety monitoring on equipment, there are no very obvious requirements for using power supply; Need to use an electrical parameter meter at level 0.5; Make the resolution of the thermocouple less than or equal to 0.1 degrees Celsius; There are no obvious requirements for using electronic scales and timers When monitoring the energy efficiency of household appliances, it is necessary to first control the power supply at 220V, with a rated frequency of 50Hz, and a harmonic distortion rate of less than 5%; The error value of the electrical parameter meter and temperature recorder used should not exceed 1%; The error between the electronic scale and the timer cannot be greater than or equal to 0.5%; The diameter of the thermocouple wire that needs to be used should be less than 0.2mm, and when it is between 0-100 degrees Celsius, the error value should not exceed 0.1; If you choose to use a thermometer, its small scale should be within 0.1 and ensure stability within 10 seconds
