What is the dwell time for the Brinell test?
Brinell test procedure. According to the standard (ISO 6506), the test load should be increased to its final value within a minimum of two to a maximum of eight seconds Generally, the dwell time for the test load is ten to 15 seconds (s). If the dwell time is any longer, the duration in seconds must also be specified in the hardness value,...
How big is the indenter ball in the Brinell test?
In case of measuring hardness for softer metals and alloys, the test load force can be reduced to 500Kgf and the indenter ball can be of diameter 5mm to 10mm. In Europe, the Brinell test is often used for small applications wherein a test load force of 1kgf and a spherical indenter of 1mm is used.
