History
The Leeb measuring method was first brought into measurement technology in 1978. It is defined as the
quotient of an impact body’s rebound velocity over its impact velocity, multiplied by 1000. Harder materials
produce a higher rebound velocity than softer materials. For a specific group of material (e.g. steel,
aluminum. etc.), Leeb hardness value represents a direct relationship to its hardness properties. For ordinary
metal, conversion curves of hardness HL versus other standard static hardness (HB, HV, HRC, etc.) are
available, enabling you to convert HL into other hardness values.
Leeb Hardness Test (definition)
An impact body with a spherical test tip made of tungsten carbide is propelled against the sample surface by
a spring force and then rebounds back. At a distance of 1mm from the sample surface, the impact and
rebound velocity of the impact body are measured by the following method: A permanent magnet embedded
in the impact body, when passing through the coil in its coil holder, induces in the coil an electric voltage
proportional to the velocities of the magnet. Leeb hardness is expressed by the following formula:
1000*
Vi
Vr
HL 
Where: HL is Leeb Hardness
Vr is the rebound velocity of the impact body
Vi is the impact velocity of the impact body
The voltage characteristic of output signal, when the impact body passes through the induction coil is
illustrated in the following figure:
Voltage characteristic of output signal
A Leeb’s Hardness Tester measures the hardness of sample material in terms of Hardness Leeb (HL), which
can be converted into other Hardness units (Rockwell B and C, Vickers, Brinell and Shore D).
Notation of Leeb’s Hardness
When measuring the hardness of a sample material using the traditional static hardness testing method, a
change of applied pressure will result in a change in the hardness reading. This will also happen during a
Leeb’s Hardness test when one changes the impact device. In hardness measurement of the same test sample
with different impact devices, the Leeb’s hardness values obtained will vary.
For example: 720HLD≠720HLC
Because different converting curves are obtained from different impact devices, when converting hardness
HL into another hardness values, the notation for the converted hardness value should include the impact
device used.
For example:
Hardness HRC converted from hardness L using impact device D should be written as 35, 9 HRCLD.
Where:35=Hardness value HL
9=Hardness value HRC
L=Leeb’s Method
D=Impact device

5 Preparation before Measuring
5.1 Requirements for the Sample
The surface temperature of sample should be less than 120 C.
The samples must feature a metallic smooth, ground surface, in order to eliminate erroneous measurements
brought about by coarse grinding or lathe scoring. The roughness of the finished surface should not exceed
2μm.
5.2 Requirements for the Weight of the Sample
For samples weighing over 5 kg and of compact shape, no support is needed.
Samples weighing between 2-5 kg, and also for heavier samples with protruding parts or thin walls, should
be placed on a solid support in such a manner that they do not bend or move by the impact force.
Samples weighing less than 2 kg should be firmly coupled with a stable support weighing over 5 kg.
For coupling purposes,
The coupling surface between the sample and base plate should be flat, plane parallel and ground.
A thin proper layer of coupling paste is to be applied to the contact surface of the sample.
The sample should be firmly pressed against the surface of the base plate by moving it with a
circular motion.
The direction of impact should be perpendicular to the coupling surface.
For the coupling operation, the following prerequisites must be fulfilled:
The contact surface of the sample and the surface of the base plate must be flat, plane parallel and
ground.
The direction of the test impact must be perpendicular to the coupled surface.
Minimum thickness of the sample for coupling (5mm).
Proper Coupling:
Proper coupling requires a little experience. Insufficiently coupled samples produce large variations of
individual measurements, L-values which are too low and the operation is characterized by a rattling noise
upon impact of the test tip.
Example for coupling a test piece with a base plate:
5.3 Requirement for the Surface Hardened Layer of the Sample
Surface -hardened steels and especially case-hardened steels produce L-values which are too low when case-
hardening depth is small because of their soft core. When measuring with impact device D the depth of the
hardened layer should be no less than 0.8 mm.
Surface of the test sample should not be magnetic.
For test sample of curving surface with radius of curvature R less than 30mm, a small support ring
should be used.

Application of the coupling
paste (As thin as possible).
A particular advanced of coupling is the possibility
of obtaining a very uniform, rigid connection
between the sample and the support, totally
eliminating stresses at the sample surface. The
resulting variation in measured values is very low.
Mutual rubbing of both
parts while firmly press the
sample against the base
plate.

When measuring hardness with this tester, the following has to be noticed: Despite the low mass of the
impact body and low impact energy, a relatively large impact force of short duration is generated when the
impact body hits the measuring surface. The max. impact force of impact device D is 900N.
For heavy samples of compact shape, no particular precautions are necessary.
Smaller and lighter samples or work pieces yield or flex under this force, producing L-values which are too
small and of excessively large variation. Even with big or heavy work pieces it is possible for thin-wall
regions or thinner protruding parts to yield upon impact. Depending on the frequency of the resilient
yielding action, the measured L-value may be too small or too large. In many situations, potential problems
can be checked in the following manner:
a) Medium-weight samples and also heavier samples with protruding parts or thin walls should be placed on
a solid support in such a manner that they do not move or flex during the test impact.
b) Light-weight samples should be rigidly “coupled” with a non-yielding support such as a heavy base plate.
Clamping in a vice is of no value, since the samples become exposed to stress and because complete rigidity
is never attained. As a rule, the measured L-values would be too small and show excessive variations.
5.4 Samples with Curved Surfaces
Impact testers only work properly, if the impact body has a certain position in the guide tube at the moment
of impacting the test surface. In the normal position, automatically present when testing flat and convex-
cylindrical samples (such as round samples), the spherical test tip is located exactly at the end of the guide
tube.
However, when testing spherically or cylindrically shaped concave surfaces, the impact body remains
further within the guide tube or protrudes further therefore. Thus, with such types of curved surfaces, it is to
be observed that radii of curvature do not drop below the values indicated in the following Fig.
Curved surfaces should always be tested with the small support ring.
Impact device types D Rmin=30mm
For impact devices D, special support rings are available to accommodate smaller radii on convex or
concave surface.
