The Element

" To check out whether the product is literally curves, measuring its geometrical parameters. Height and width of diagonal metal tape measure parallel to the edge glass. Thickness of a product is measured using the gauge at four points (in the middle of each side of glass). The results should be within tolerances. Surfaces clean glass the presence of different chips and detect visual damage in diffused daylight. Another test which are the control samples after the party making glass, is the definition of optical distortions.

The essence of the method of evaluation is that through the windows looking at the screen like "zebra", which is a system of equally spaced black and white stripes, inclined at an angle of 45 to the horizontal. Image should remain unchanged under any scenario of view. Like the profile, windows must be tested for resistance to weathering products (GOST 30779-2001). Sample is cyclically repeated harmful effects: saline solution, ultraviolet irradiation, alkali, freeze, acid, heat. Windows, which went through 12 such cycles, found fit to a 7-year life.

If the number of covered cycles is more or less a guarantee of quality is determined by extrapolation. Tests for quality furniture fittings, not only last for a long time, but will also provide additional comfort and safety in the home. Many producers of the element window system has established a process for control of products for a number of parameters. For example, in the company of Kale, it runs every 15 minutes in all stages of manufacturing furniture.
