3 Terms and definitions
The terms and definitions defined in GB/T 35165 apply to this document.
4 Principle
The dry sample is placed on two circular shafts and a load is applied to the middle of the sample to measure the load value at the time of the fracture of the sample, thereby calculating the bending.
strength.
5 instruments
5.1
The balance with a measurement accuracy of not less than 0.01% of the sample quality.
5.2 A blast drying oven capable of maintaining temperatures between (40 ± 5) °C and (70 ± 5) °C.
5.3
Measurement tools with a measurement accuracy of not less than 0.1 mm.
5.4 Test machine
The relative error of the indication value does not exceed ±1%, and the load of the sample damage is within the range of 20%~90% of the indication value of the equipment.
5.5 Specimen loading device
consists of two support shafts and a load shaft that applies pressure at the center. The distance between the two support shafts should be
The sample length can be adjusted, as shown in Figure 1. The diameter of the three shafts should be no more than 20mm and the length should be greater than the width of the specimen.
