COMPANY INFORMATION Part of the INNOVATECH Holding, Group of companies, based in The Netherlands. With its foundation laying in the 19th century (1890) INNOVATEST® has a rock solid position in the market of materials testing instruments, optical measuring equipment and general testing instruments such as surface roughness, wall thickness, vibration, and other portable testing equipment. For the last 25 years, the owners have largely invested in the product tier Hardness Testing, while still keeping their focus on other product lines. Commitment With a wide range, - fit to any budget -,...

HARDNESS TESTING HARDNESS Hardness is the property of a material enabling it to resist plastic deformation, usually by penetration of another object. The term “hardness” may also refer to stiffness, temper or resistance to bending, scratching, abrasion or cutting. Scientists and journalists often confuse stiffness with hardness. This however is incorrect. Osmium (platinum family) is stiffer than diamond but not as hard as diamond. The usual method to obtain a hardness value is to measure the depth or area of an indentation left by an indentor of a specific shape, with a specific force...

HARDNESS TESTING Knoop (HK) Indenting the test material with a “elongated” diamond pyramid, subjected to test forces usually not exceeding 1kgf. A precision microscope or high resolution USB camera is used to visualize and measure the indentations, magnifications up to 600x are most common. Brinell (HB) Indenting the to be tested material with a 1, 2.5, 5, or 10mm diameter hardened steel or carbide ball subjected to a load/force ranging from 1 to 3000kg. A microscope or USB camera is used to visualize and measure the rather large indentations. Leeb (HL) (rebound method) Portable hardness...

All instruments in this catalogue are calibrated to ISO/EN/DIN, ASTM or factory standards. INNOVATEST® supplies each hardness tester with a traceable calibration certificate. Hereunder follows a part of the list of the participating organizations in the multilateral agreement WECC dated December the 1st 1989 and the respective brands showing on the calibration certificate of each individual organization. The purpose of the harmonization of all local standards is to create a cross border platform of quality standards with no need to apply for new certificates in the other participating...

ROCKWELL HARDNESS TESTERS 90 YEARS OF ROCKWELL TESTING HISTORY The Rockwell Hardness test is a hardness measurement based on the net increase in depth of impression when a load is applied. Hardness values are commonly given in the A, B, C, R, L, M, E and K scales. The higher the value in each of the scales, the harder the material. Hardness has been variously defined as resistance to local penetration, scratching, machining, wear or abrasion. In the Rockwell method of hardness testing, the depth of penetration of an indentor under certain arbitrary test conditions is determined. The...

ROCKWELL HARDNESS TESTERS The superficial Rockwell scales use lower loads and shallower impressions on brittle and very thin materials. The 45N scale employs a 45-kg load on a diamond cone-shaped Brale indentor, and can be used on dense ceramics. The 15T scale employs a 15-kg load on a 1/16inch diameter hardened steel ball, and can be used on sheet metal. Readings below HRC 20 are generally considered unreliable, as are readings much above HRB 100. Typical values Very hard steel (e.g. a good knife blade): HRC 55 - HRC 62 Axes, chisels, etc.: HRC 40 - 45 Several other scales, including the...
