Description
Но существующим методам контрили н;1иу л:ен1п в закаленном плоском стекле измерению подвергаютс лишь напр жеHU5 в средней плоскости образца, между тем как существенпое значение имеют iaир жени на поверхности стекла, ои1)едел ющие его прочность в услови х :окенлуатации . Непосредственное измерение наириженнн на поверхности илитки стекла путем просвечивани в торец при оольИ1ИХ стеиен х закалки оказываетс практически певозмо кным из-за больиюго градкента нанр жении.But the existing methods of contouring n; 1iu l: en1p in hardened flat glass are only measured on the HU5 stress in the sample's mean plane, while the iair on the surface of the glass, oi1), which diminishes its strength under the conditions of occluluation, are essential. Direct measurement on the surface of an emitter of glass by means of translucent end-to-face during the course of quenching hardening is almost song-like due to a large gradient of force.
Согласно изобретению, наир жение на поверхности закаленного плоского стекла оиредел етс следующим образом.According to the invention, the deflection on the surface of tempered flat glass is determined as follows.

The sample is then doped bilaterally or unilaterally so that reduction of its thickness) is 1-2 / n. The measurements of the waves, | and the voltage, are repeated again. The operation of the song is re-measured by a tolith i; for example, it is produced once, after which it is built
