Ball Pressure Test

This test method is used to determine dimensional stability under stress at elevated temperatures.

It analyses the relationship between the degree of deformation and the temperature when the test specimen is subjected to a constant load.

Ball pressure test


Test specimen 127 mm x 12,7 mm x 3 mm
Temperature range 23 °C bis 300 °C
Ball diameter 5 mm
Duration of test 60 min
Weight 20 N


Results of the test method

Temperature at which the ball produces an indentation measuring
2 mm in diameter.
