After two years of revision, the National Standardization Management Committee recently approved the new national standard 'GB/T 4288-2018 electric washing machines for household and similar purposes' and plans to implement it on October 1 this year. The new washing machine GB changes the capacity of washing machines. Nominal method, increase the abrasion 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 designation of washing machines and dewatering machines, and uses kilograms as the unit of rated washing capacity, according to the ratio of washing, washing uniformity, water consumption, and water use. The amount, noise, moisture content, and trouble-free operation time divided the washing machine into four grades: A, B, C, and D. However, many problems were found after implementation. For example, consumers could not clearly understand the capacity of the washing machine through quality, and even a few manufacturers used it. Opportunity, 'virtual label' capacity, the primary purpose of the new standard is Debug.
capacity
In the old standard, the maximum mass of washable dry laundry was used as the rated load. This brought a problem. The density of different fabrics was different. The same was 0.5 KG, one garment might be 0.3 L, and the other was likely to change. Into 0.5L. So some opportunistic to create some small size and large washing quality of the washing machine, these products do wash 5, 6KG clothes, can put a few pieces of low-density space inside the barrel of the stuffed, the use experience is very poor.
In the new standard, the rated capacity is used instead of the rated load. The unit is L. When measuring the rated volume, a thin plastic bag is first put into the inner drum of the washing machine and filled with clean water. Then the weight difference before and after the water injection is calculated and finally the weight difference is calculated. Calculate the volume and take the average of the three tests as the final result. After replacing the kilogram with liter, the consumer will be able to clearly understand the true capacity of the inner drum of the washing machine. (It is not clear how much the 1L has, and the bottle of big cola can be known. )
naming method
The old standard specifies the rated load as part of the washing machine model. Now replacing the nominal load with the effective volume, the naming scheme naturally needs to be modified. Under the new standard, the washing machine name naming convention is mostly maintained with the old standard, but the quality value is replaced by the volume. , Change the value of the rated load by 10 to the capacity value (rounding). For example, a washing machine with a rated load of 7 KG and an effective volume of 60.3L is named under the old standard name 'XQB70-MZ'. To the new standard will become 'XQB60-MZ'
PS: The specification of the dehydrator is still expressed as the value of the dewatering mass (KG) multiplied by 10, the value does not represent the volume.
Go to Class D plus Class A+
Debug is just one of the goals. In order to promote industrial innovation and bring better washing machine products to consumers, the new standard adopts a more stringent grading standard and removes grades A, B, C, and D. At the lowest D level, the A+ level was added. This is like creating 101. It was originally divided into four classes A, B, C, and D. However, after the new round of competition, all classes A, B, and C cannot be selected. Praise became A+ class.
If you look at the details of the competition rules again, you will find that a new test item has been added to the new standard assessment level—the wear rate of (clothing). That is to say, as long as you assess vocal music and dance, you need to assess the ability of the players to sing. The strength is not all brushed down.
After 10 years of implementation of the GB/T 4288-2008 standard, it has been impossible to effectively protect the rights and interests of consumers. The introduction of new standards is imperative. The new standard will also eliminate companies that lack market strength and do not meet the specifications. Market environment.
