Measuring principle

UCI Method, corresponds to DIN 50159, ASTM A1038

Test indenter

Vickers diamond 136°

Test loads
Newton scale (1kgf = 9.81 N)

Motor probes: 1N (0.1 kgf), 3N (0.3kgf) and 8.6 N (0.9 kgf) Handheld Probes: 10N (1 kgf), 30N (3kgf), 49N (5kgf), 98N (10kgf), (Other test loads on request)

Hardness scales and range
(according to relevant standards), in this case table A1 respectively T1, T2 (low alloy steel). Different measuring ranges are valid for other materials. When exceeding the limits the conversion range will be extended. The calculated values are highlighted in red besides the original data in HV.

Note:
Conversions are acc. to latest ASTM E140-12b^Ԑ1 (2013) and EN ISO 18265:2014.
Conversions into tensile strength: 98N (10kgf) test load only.
