Choosing a washing machine, the buyer pays attention to the characteristics that will satisfy the needs of the family budget and save. To make it easier to navigate, the technique began to classify. The key parameters are considered to be the quality of washing, spin class in washing machines and electricity consumption.

Classification
The common classification for the washing machine is made up of seven letters of the alphabet:
- The highest quality score is indicated by the letter A. According to the numerical indicator of efficiency is 1.3. Such an apparatus will deliver any type of fabric contaminants complex per cycle.
- The second level corresponds to the letter B, which means efficient wash. The numerical quality score from 1 to 1.3.
- Evaluation With the third highest efficiency. Numeric results estimated from 0.97 to 1.
- Last quality is assessed by the letter D. The device of this class washes most tissues with complex pollution. The numerical value from 0.94 to 0.97.
Among the class of washing in washing machines A, B, C and D - the best performance. The rest of the E, F and G are not currently assigned. These characteristics are found only in the secondary market.
How to determine the class of washing and power consumption
Class membership model is established as a result of the test. The performances are compared with the certified parameters of the machine with the most stable results. These devices are produced by authorized manufacturers by European standards.
Test conditions:
- Cycle duration 60 minutes;
- temperature 60 °;
- the same type of tissue with the same contaminants;
- a laundry detergent.
The results are recorded and are evaluated automatically. Performance indicator is determined and assigned to the appropriate class. Thanks to modern technology effectively verifiable model of reference. Therefore it is reasonable to choose the device A class than the reference sample.
spin class
Spin in the washing machine is also verified experimentally. The principle of the test in weighing the fabric before and after treatment. The smaller the difference, the better the machine will press the laundry after washing.
To work in the extraction mode is influenced by:
- drum speed;
- drum diameter;
- continuous operation;
- material type.
Squeezing efficiency class assigned to the washing machine is denoted by the same letters of the alphabet. Performance Index is a percentage. And for this humidity to 45% from the initial level. In the first three levels of it from 45 to 63%.
Increased activity of the drum speed can damage clothes.
energy class
Class wash and spin in a washing machine - is not the only performance that is worth to take into account when buying. An important indicator is considered to be energy efficiency - energy consumption, with which the device is able to wash the linen kg per hour.
For each new model, this parameter is set experimentally:
- taken kg cotton fabric;
- hour wash at 60 °;
- measure the electricity consumption.
With the development of technology has increased efficiency devices. Of the seven levels of energy consumption was only A. His efficiency from 0.17 to 0.19. Pattern with minimum energy consumption are three levels A to the number of "+" marks from 1 to 3.
Each icon indicates a 10% saving electricity:
- A + 10%;
- A ++ 20%;
- A +++ 30%.
What to look for when buying
Despite the seven levels of the quality of work in the wash mode, demand only the first three. The difference between A and B is indistinguishable visually. Devices are not recommended to buy with the assessment of C, since the results of their work below.
By the level of extraction is sufficient quality of the S. This is enough to prepare the laundry for drying without damaging its frequent rotation of the drum. By energy consumption is competition samples A +++, ++ A and A +.
According to established standards, to select the required characteristics are indicated on the rear of each device are duplicated on the original packing and accompanying documents. The store basic parameters indicated on the price list.
