It is one of the classic conventional test methods for evaluating hardness, whereby an allocation to the small load or micro range was made from the outset and 10 N was recommended as the highes...") | ||||

The IRHD hardness is determined in accordance with ISO 48-2, which was...") | ||||

Thus, a hard body resists the indentation of a foreign body more than a soft one, from which it can be directly derived that hardness i...") | ||||
