Why do water bottles need to be tested by dishwashers?

A dishwasher is an appliance used to clean dishes, bottles and other items. Its invention and production dates back to the early 1900s. The earliest dishwasher was invented by an American named Josephine Cochrane in 1886 to solve the problem of dishwashing in households. At that time, dishwashing was done manually by maids, while Josephine Cochrane’s dishwasher could automate the cleaning process, greatly improving cleaning efficiency.

With the passage of time, the design and technology of dishwashers continue to improve, from the initial manual operation to the current fully automated and intelligent operation. In the 1950s, dishwashers began to enter the home and gradually became popular. Today, dishwashers have become one of the indispensable home appliances in modern households.

With the popularity of dishwashers, the dishwasher test has gradually become a standardized test method to test the cleaning effect of dishwashers. It is to test the cleaning effect of dishwashers on dishes, bottles and other items by simulating the actual use of the situation, in order to ensure that the cleaning effect of the dishwasher meets the standard, and provide consumers with a better cleaning experience.

Why conduct dishwasher testing? First of all, dishwasher is a commonly used home appliance and its cleaning effect is directly related to people’s hygiene and health. If the cleaning effect of dishwashers is not good, harmful substances such as bacteria and viruses on utensils, bottles, and other items cannot be effectively removed, which may pose a threat to people’s health. Second, dishwasher testing can help consumers choose dishwasher products that better meet their needs and improve their buying experience.

Water bottles are essential items in our daily life, and dishwasher testing can ensure that the cleaning effect of water bottles in the dishwasher meets the standard, ensuring the hygiene and health of water bottles. In addition, the dishwasher test can also test the cleaning effect of different materials and shapes of water bottles in the dishwasher, helping consumers to choose a more suitable type of water bottle. People are accustomed to using dishwashers, coupled with the bottle shape of the sake of the bottle is not easy to clean, so people who own dishwashers will put the bottle in the dishwasher for cleaning. In the early days, the surface spraying technology of stainless steel cups was not mature, especially the surface printing technology. In addition, many materials used for stainless steel cups were not up to standard. After cleaning, the surface paint would fall off, and the printed patterns would be blurred. Especially for some materials that were not up to standard, obvious blackening and corrosion would occur in the inner liner after cleaning with detergent. As a result, some countries have formulated dishwasher testing standards for water cups and require them to pass the standards before entering the market.

So what are the dishwasher test standards? Dishwasher test standards are usually developed by the International Organization for Standardization (ISO) and Comité Européen de Normalisation (CEN) and other institutions. One of the most commonly used dishwasher testing standards is the ISO 8442-2 standard, which specifies requirements for dishwasher cleaning effectiveness, cleaning time, water temperature, and amount of detergent used. In addition, there are some other standards, such as the European standard EN 50242, the American standard ANSI/AHAM DW-1 and so on. In conclusion, the invention and production of dishwashers can be traced back to the early 20th century. With the passage of time, the design and technology of dishwashers have been improved and gradually popularized into modern households. Dishwasher testing, as an important standardized test method, ensures that the cleaning effect of dishwashers meets the standards and safeguards people’s hygiene and health.

Dishwasher testing standards are not uniform across the globe, and vary by geographic regions, countries and brand requirements. By the beginning of 2023, these standards will gradually be harmonized, even if there are some differences, but they will still fluctuate around a base. This basic standard is: for the surface sprayed with paint or plastic powder and do the pattern printing treatment of stainless steel bottles, in full accordance with the dishwasher a standard operation and continuous implementation of 20 times and above, after cleaning the surface of the stainless steel bottles can not appear paint peeling, pattern blurring or disappearance of the inner liner of the bottles thoroughly cleaned will not appear blackened and corrosion phenomenon, at the same time, the bottles as a whole will not occur deformation, shrinkage and other issues. The bottle will not be deformed, shrinkage and other problems. And so the bottle of water to dry naturally after the insulation test again, not because of dishwasher cleaning caused by the bottle of water performance decline.

In summary, dishwasher testing is a very important standardized test method, it can ensure that the cleaning effect of the dishwasher in line with the standard, to protect people’s health and hygiene. At the same time, the dishwasher test can also help consumers choose dishwasher products and water bottle types that better meet their needs, and improve the consumer’s buying experience.
