Application
The Button Impact Tester is designed to assess the impact resistance of plastic sew-through flange buttons. The tester evaluates the button’s ability to withstand a falling mass of 0.84 kg (29.5 oz), released from heights of 32mm, 44mm, 67mm, 83mm, 95mm, 117mm, or 200mm, as required. Failure is determined by cracking, chipping, or breakage of the button.
Testing Method
Bursting Strength Test Procedure
The Bursting Strength Tester uses continuous pressure to determine the tensile strength of fabric, paper, or board until it bursts. The tester calculates the bursting strength based on the burst time and pressure using intelligent algorithms, and the results are presented via PC-controlled software. The tester is suitable for various standards and provides an accurate calculation of bursting strength.
Bursting Strength Calculation Formula
Bursting strength (kN/m²) = A – B
Where:
- A is the average burst strength (kN/m²)
- B is the number of diaphragm calibration (kN/m²)
Note: 1 MPa = 1000 kN/m²
Calibration Process
To calibrate the tester, compare the results of a sample test with the calibration plate under the same parameters. If the results match, no further calibration is needed. Otherwise, adjust the calibration pressure and set the tester to the correct value.
Types of Bursting Strength Testers
This tester can evaluate the bursting strength of various materials, including:
- Fabric (woven and knitted)
- Paper and cardboard
It is widely used in industries such as textiles and packaging for testing materials’ resistance to bursting under pressure.
