1. Forewords
1.1. 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.
1.2. 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
Vris the rebound velocity of the impact body
Viis 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, Vicker,
Brinell and Shore D).
1.3. 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
2. Features and Applications
2.1. Introduction
This instrument is an advanced state-of-the-art palm sized metal hardness tester with
many new features which are light weight, easy operation, integrated design, high
contrast display, low operating temperature, auto compensating for impact direction and
etc. It can be widely used for measuring hardness of almost all ferrous and non-ferrous
metal materials for scale of Leeb hardness, Rockwell C, B &A, Brinell, Vickers, Shore and
Strength.
It has a memory capacity of 400 blocks and 360000 data which can be downloaded to
computer via USB or Bluetooth (Optional). The measuring value can be printed out from
tester to micro-printer by USB or Bluetooth. All stored data can be recalled and read on
the tester easily.
It also has a very unique feature, which impact device can convert between D and DL
simply by changing impact body. This two-in-one probe is equivalent to two individual
probes. With this optional accessory, you can take measurement at very narrow surface
such as slot bottom, gear tooth that probe D cannot match.
The 3.7V Li-ion rechargeable battery inside the tester can be charged via USB from PC or
via individual battery charger from mains wall power. With data software for PC,
customers can download measuring values from THE TESTER to PC and make process
such as save, delete, create testing report and export them to Excel.

5. Preparation before Measuring
5.1. Requirements for the sample
5.1.1. The surface temperature of sample should be less than 120 C.
5.1.2. 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

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.

with impact device D/DL the depth of the hardened layer should be no less than 0.8 mm.
5.4. Surface of the test sample should not be magnetic.
5.5. For test sample of curving surface with radius of curvature R less than 30mm, a
small support ring should be used.

0.05 - 2 kg
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/DL 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.
5.7. 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.
