IEC 60320-1 Clause 24.1.2
The ball pressure test is made on plastic materials to check their resistance to heat.
The test specimen is placed in an oven a weight
with a ball-shaped tip is placed onto the test specimen.
If the test specimen becomes soft, the ball will make a dent.
By measuring the diameter of this dent, the heat resistance of the material can be classified.
