1 .I This part of IS0 2039 specifies a method for determining
the indentation hardness of plastics by means of the Rockwell
hardness tester using the Rockwell M, L and R hardness scales.
1.2 A Rockwell hardness number is directly related to the indentation
hardness of a plastic material; the higher the
Rockwell hardness number, the harder the material. Due to a
short overlap of Rockwell hardness scales by this procedure,
two different Rockwell hardness numbers of different scales
may be obtained on the same material, both of which may be
technically correct.
1.3 For materials having high creep and recovery, the timefactors
involved in application of the major and minor loads
have a considerable effect on the results of the measurements.
1.4 An alternative method of using the apparatus to give
hardness on the Rockwell-cc hardness scale is specified in the
annex which shows how this scale may be related to the hardness
measurement of IS0 2039-l.
