Скачать или смотреть Glass Bending Strength DIN EN 1288 3

4-point bending test on glass according to DIN EN 1288-3 with the special testing machine EM-STB 5 kN.

Testing machine
The bending test shall be carried out using a suitable bending testing machine, which shall incorporate
the following features.
a) The stressing of the specimen shall be capable of being applied from zero up to a maximum value in a manner which minimizes shock and is stepless.
b) The stressing device shall be capable of the specified rate of stressing.
c) The testing machine shall incorporate a load measuring device with a limit of error of ±2,0 % within the measuring range.
d) The supporting rollers and the bending rollers (see Figure 2) shall have a diameter of 50 mm and a length of not less than 365 mm. All the rollers shall be free to rotate.
A workspace width of 1300 mm and a workspace depth of 650 mm can be realised.

Furthermore, the design of the Inspekt S 50 enables modified test space sizes for different glass sheet dimensions.Special testing machine for glass testing
