What are the Dishwasher Test Standards?Why should the water cup pass the dishwasher test?

Today's title is two questions, why does the editor write an article about dishwashers? One day, when the editor was searching for the content he wanted to know through the Internet, he found a content about the dishwasher test standard included in a certain entry. A simple matter made the editor see two unprofessionals, and the person who answered this question first I think is unprofessional. The content of the answer can be said to be completely explained based on personal feelings, or the answer to this question has other purposes.

At least the editor thinks that if the dishwasher test standard is as he said, it is not a standard, but a dispensable standard.May I ask when was the dishwasher invented? Why is there a dishwasher test standard for dishwashers? Secondly some are too irresponsible, does the answer to a question have a price and the science doesn't seriously understand the research? The content included in this way is a serious misleading for newcomers and consumers who do not understand or have just entered the industry.

The editor first answers the second question, why is the water cup tested in the dishwasher?

The dishwasher was invented in 1850, and the real commercial production of the dishwasher was produced by a German company in 1929.After nearly 100 years, dishwashers have been continuously developed, upgraded and optimized by many companies, until now they are popular in many families. The editor does not advertise for any electrical appliance company, so I will not introduce who produces better products.

The popularity of dishwashers not only reduces people's labor, but also ensures that the kitchen utensils cleaned by dishwashers are cleaner. Friends who have used dishwashers have a habit of not washing kitchen supplies independently because of different functions. Most of the items that need to be cleaned are placed in the dishwasher at the same time, and then washed together. There will be ceramics, glassware, wooden utensils, stainless steel products and so on. The water cup is also a member that will be placed in it for cleaning.

Why do water cups have to be tested in the dishwasher? The reason is actually very simple, because people are used to the dishwasher, and the shape of the water cup is not easy to clean, so people who own a dishwasher will put the water cup in the dishwasher for cleaning. In the early days, the surface spraying technology of stainless steel water cups was not mature, especially the surface printing technology of water cups.

In addition, the materials used in many stainless steel water cups are not good enough. After cleaning, it will be found that the surface paint has peeled off and the printed pattern is blurred. In particular, some materials that are not up to standard have obvious blackening and corrosion in the inner tank after cleaning with detergent. Complaints from the market are increasing at any time, so some countries have formulated mandatory water cup dishwasher test standards for water cups, and require that they must pass, and only those that pass can enter the other party's market.

So what are the test standards for dishwashers? The test standards for dishwashers are not completely consistent around the world, and will vary according to geographical regions, countries and brand requirements. By the beginning of 2023, these standards will gradually be unified, and even if they are somewhat different, they will still fluctuate around one basis. The basic standard is: For stainless steel water cups that have been sprayed with paint or plastic powder and processed with pattern printing, they must completely follow the standard operation of the dishwasher and perform 20 or more consecutive operations.

After cleaning, the surface of the stainless steel water cup should not have paint peeling off, and the pattern should be blurred or disappear. The inner liner of the water cup is cleaned thoroughly without blackening and corrosion, and at the same time, the water cup as a whole will not be deformed or shrunk. After the water cup dries naturally, the heat preservation test should be carried out again, and the performance of the water cup cannot be reduced due to washing in the dishwasher.

A standard operation: the water temperature of the dishwasher is 75°C, put in the corresponding standard amount of detergent and dishwashing salt for a standard cycle of cleaning for 45 minutes.
