This standard specifies the performance testing methods for coffee machines for household and similar purposes. This standard applies to coffee machines for household and similar purposes, but does not apply to appliances specifically designed for commercial or industrial use. The purpose of this standard is to explain and define the main performance characteristics of coffee machines of interest to users, and to describe standard methods for measuring these characteristics. This standard does not address the safety and performance requirements of the product. Due to differences in time and testing materials, components, and subjective judgments of experimental operators, when considering accuracy and repeatability, using the testing method described in the standard for approximately the same time period in the same laboratory using the same instrument by the same operator will have higher reliability than testing a certain instrument in different laboratories. Note 1: Similar use refers to the use of appliances in a similar manner in a normal indoor environment, such as in an office, except for household use. Note 2. The measurement method of this standard is used to test coffee machines with specific purposes such as coffee filters, filter coffee machines, and pressure coffee machines. This standard is also applicable to testing coffee machines with other functions. 2 Normative References: The clauses in the following documents become clauses of this standard through reference in this standard.

In a continuous process, hot water passes through an upward pipeline and then flows downwards through the ground coffee powder before flowing into the container. 3.3 Drip Coffee Machine Filter Coffee Maker A coffee machine with an independent water container. The ground coffee powder and filter are installed above the coffee container, and hot water flows into the coffee container through the filter containing the ground coffee powder. 3.4 Pressure coffee maker A coffee machine that heats water and then uses steam pressure or a pump to force the water through ground coffee powder and filter to make coffee
