Abstract: The electric pressure cooker is an upgraded product based on the rice cooker combined with the advantages of the ordinary pressure cooker. It solves the pressure safety problem of the pressure cooker. The increase of the pressure in the pot can speed up the cooking process of the food and save the cooking time. The implementation of electric pressure cooker energy efficiency standards can provide a standard basis for the industry, promote electric pressure cooker manufacturers to improve their products, and contribute to the healthy development of the electric pressure cooker industry. The research can provide a reference for the laboratory of electric pressure cooker manufacturers and third-party testing institutions to control the testing process and improve the measurement accuracy.

Key words: Electric pressure cooker, Uncertainty, Energy efficiency value
