After two years of revision, the National Standardization Administration recently approved the new national standard “GB/T 4288-2018 Household and similar electric washing machinesâ€, and plans to officially implement it on October 1 this year. The new washing machine national standard has modified the nominal mode of washing machine capacity to increase the wear test. How do we choose washing machine products under the new standard?
The current washing machine standard GB/T 4288-2008 was implemented in 2008. It regulates the naming method of washing machines and dewatering machines. It uses kilograms as the unit of rated washing capacity, according to washing ratio, washing uniformity, water consumption, water consumption. The quantity, noise, moisture content and trouble-free running time divide the washing machine into four grades A, B, C and D. However, after implementation, many problems were found. For example, consumers cannot clearly understand the washing machine capacity through quality. Even a few manufacturers use speculative and "virtual standard" capacity. The primary purpose of the new standard is Debug.
capacity
In the old standard, the maximum mass of disposable laundry is used as the rated load, which brings a problem. The density of different fabrics is different, the same is 0.5KG quality, one piece of clothing may be 0.3L, and the other is likely to change. In 0.5L. Therefore, some speculations make some small-sized washing machines with small washing quality. These products do wash 5, 6KG clothes, and can be filled with a few low-density clothes in the inner barrel space, and the experience is extremely poor.
In the new standard, the rated capacity is used instead of the rated load in L. When measuring the rated volume, a thin plastic bag will be placed in the inner tub of the washing machine and filled with clean water, then the weight difference before and after the water injection will be calculated. Finally, the volume will be calculated based on the weight difference, and the average of three tests will be taken as the final result. After using liters instead of kilograms, consumers can clearly understand the actual capacity of the barrel inside the washing machine. (I really don't know how much 1L is. I know when I take the bottle of Coca-Cola.)
naming method
The old standard stipulated that the rated load is part of the washing machine model. Now the effective load is used instead of the rated load, and the naming method is naturally modified. Under the new standard, the washing machine name naming convention is mostly kept up to the old standard, but the mass value is replaced by the volume, and the value of the rated load is multiplied by 10 to the capacity value (rounded). For example, a washing machine with a rated load of 7KG and an effective volume of 60.3L is named "XQB70-MZ" under the old standard name, and becomes "XQB60-MZ" under the new standard.
PS: The specification of the dehydrator is still the value of the dehydration mass (KG) multiplied by 10, and the value does not represent the volume.
Go to D class plus A+ class
Debug is only one of the goals. In order to promote industrial innovation and bring better washing machine products to consumers, the new standard adopts a stricter classification standard and removes the grades in the A, B, C and D standards. The lowest D level, the new A+ level. This is like creating 101. It was divided into four classes A, B, C, and D. However, after the new round of competition, all classes A, B, and C could not be eliminated. Among them, the praise king became the A+ class.
If you look at the rules of the game in detail, you will find a new test item - (clothing) wear rate when the new standard is rated. In other words, as long as the assessment of vocal music and dancing, it is now necessary to assess the ability of the players to sing, and the strength is not enough to brush down.
After 10 years of implementation of the GB/T 4288-2008 standard, it has been unable to effectively protect the rights and interests of consumers. It is imperative to introduce and implement new standards. The new standard will also eliminate manufacturers with insufficient market strength and non-compliance, and purify the market environment.
