Today’s title is two questions, so why write about dishwashers? One day when I was searching for what I wanted to know on the Internet, I found content about dishwasher testing standards that was included in a certain entry. A simple thing made the editor see two unprofessional people who were the first to answer this question. I think it is unprofessional. The content of the answer can be said to be completely based on personal feelings, or the question has other purposes. At least we think that if the dishwasher test standard is like what he said, then it is not A standard, but a dispensable standard.
I would like to ask when the dishwasher was invented, and why is there a dishwasher test standard for dishwashers? Secondly, someone is too irresponsible. Is the answer to a question valuable and scientific without serious understanding of research? Such included content is seriously misleading to newcomers and consumers who do not understand the industry or have just entered the industry.
Let’s answer the second question first: why do water cups need to be tested for dishwashers?
The dishwasher was invented in 1850, and the actual commercial production of the dishwasher was produced by a German company in 1929. After nearly 100 years, the dishwasher has been continuously developed, upgraded and optimized by many companies until now. Popular in many families. We don’t advertise to any electrical appliance company, so we don’t introduce who makes better products or anything like that.
The popularity of dishwashers not only reduces people’s labor, but also ensures that the kitchen utensils washed by the dishwasher are cleaner. Friends who have used dishwashers have a habit. When cleaning kitchenware, they do not wash them independently because of their different functions. Most of them put the items that need to be cleaned into the dishwasher at the same time and then wash them together. There are ceramics in them. utensils, glassware, wooden utensils, stainless steel products, etc., water cups will also be placed in them for cleaning.
Why do water cups need to be tested for dishwashers? The reason is actually very simple. People are accustomed to using dishwashers, and the shape of the water cup is difficult to clean, so people who own dishwashers 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 printing technology on the surface of water cups. In addition, the materials used in many stainless steel water cups were not up to standard. After cleaning, you will find that the surface paint peels off and the printed pattern is blurred, especially some materials are not up to standard. After cleaning with dishwashing liquid, the inner tank showed obvious blackening and corrosion, and market complaints continued to increase at any time. Therefore, some countries have formulated necessary water cup dishwasher testing standards for water cups, and require them to pass. Only those who pass can enter. the other party’s market.
So what are the testing standards for dishwashers? The testing standards for dishwashers are not completely consistent around the world and will vary according to geographical regions, countries and brand requirements. As of the beginning of 2023, these standards will gradually become unified, and even if they are somewhat different, they will still fluctuate around the same basis. This basic standard is: For stainless steel water cups with paint or plastic powder sprayed on the surface and pattern printing, they must be fully operated according to a standard dishwasher and performed continuously for 20 times or more. The surface of the cleaned stainless steel water cup must not have paint peeling off. , the pattern is blurred or disappears, and the inner tank of the water cup will be completely cleaned without blackening or corrosion. At the same time, the overall water cup will not be deformed or shrunk. Wait for the water cup to dry naturally and perform the heat preservation test again. The performance of the water cup should not be reduced due to dishwasher cleaning.
A standard operation: the dishwasher water temperature is 75°C, put in the corresponding standard amount of detergent and dishwashing salt, and perform a standard cycle of 45 minutes.
