12Durometer &IRHD Hardness Tester
Abandunt Lineups of Hardness Testers for ISO
and JIS standard.

Durometers show the degree of hardness byvalue whether a non-rigid material like rubber
is soft or hard (hardness gauge for rubber orplastic).Recently, JIS standard and ISO
standard have been drastically revised anddetails of hardness tester of rubber andmethod of measuring hardness are changed.
As an all embracing manufacturer of
non-rigid material hardness tester, Teclock
proposes lots of measuring methods ofmeasuring hardness of not only rubber andplastic but many non-rigid materials andelastic materials.

Durometer Sensor

IRHD(M-method) Hardness Tester for standard canmeasure hardness of O-ring, small rubber parts andthin rubber sheet.

Pocket type and Digital
Durometer with peakhold type.

In order to solve individual difference of measured value, it isclearly mentioned in the standard to measure hardness bymounting durometer to special stand.

Original designed the key parts

Sleek and Ergonomic design

We develop the products after in pursuit of mesurement
quality by easy to hold shape, pressured suface shape forsufficient adheision to work piece and ergonomic design.

Features, Measuring hardness, Durometer standard

We develop and design the most critical mechanical parts,
movements. So, Original Durometer was developed as theapplication measurement equipment of dial gauge using rackand pinion etc.. These movements are supplied to otherdurometer companies by OEM.

Lineups best in the world

Calibration certificate can be issued

Teclock can originally issue 3 kinds of traceability system
diagram, calibration and inspection report.

The variety of materials, from Urethane foam to Plastic canbe mesured by Teclock Durometer. So, We design thePressurized Face shape for sufficient adhesion to many work
materials. Number of Lineups is best in the world.

Measuring hardness with Durometer
1) In case of measuring by pushing by hand, putting pressurized surface ofdurometer held by hand from the top vertically with a certain speed to the flat faceof work piece which is put on the flat face . Then, after adhering it, regard the value
measured within the passed time prescribed by standard as “hardness”
2) In case of measuring hardness by mounting
Pointerdurometer to stand, measuring speed (not morethan 3.2mm/sec.), pressurized load (type A, E isDial
1kgf, type D is 5kgf) and pressurized surface
Peakdiameter (φ18mm) of type A / D durometers
Pointer
including tolerance are standardized.
3) Measuring point of test piece is to be insidefrom its edge by 12mm or more and clearance is
to be 6mm and more. Thickness is normally 6mm
and more, and 10mm and more for type E.
4) Test environment : Temperature is 23℃±2,
Limiterhumidity is 50±5% and median or average isapplied for measured value. If 50 show in type Acase, it is described[A50]. These are ruled forBase
Indentereach standard.

As to measuring hardness by pushing byhand, durometer to work piece form the
top and read value by making pressedsurface adhere to durometer.

In order to solve
individual difference ofmeasured value, it isclearly mentioned inthestandard
tomeasure hardness bymounting durometerto stand.

Model Selection of Durometer

There are many type of durometers
based on spring force, contact point size
and its shape. This is according to theinternational standard, in order to havethe most accurate and the precise
results with the several shape of works
and those material characteristic.
Teclock durometers are in comply with
the international standards, but also
have an own standard to measure thevariety of materials.Please refer to thetable below to choice the most suitablemodel.

Mechanism of the hardness
measurement

SpringContact point with the pressurizing
force gives deformed surface.
Then, a work piece makes force
against this force.Hardness means thatwhen both pressurizing force andrepulsiveforce
areequivalent,measure the depth of indentor. The
depth of indentor indicates from 0 to100. This figure shows the values ofhardness. The figure has no force unit,
but only relative physical value.

Some of Rubbers, Elastomer' elastic body is not easily read the maximum value after firm
contacting with a presser foot of durometer , due to the stress relaxation. The pointer indicates thedescendent value but the peak pointer is holding the maximum measured value. The peak pointertype can easily read the maximum value efficiently. In case the pointer cannot be read directly due
to some obstacles altough the measuring can be done, the mesured value can be confirmed frompeak pointer after measuring. The upper / lower limiters equipped will be effectively used intolerance judgment.

Elastomer. One of the test items is hardness test andrubber industry generally calls type A durometer“shore-A” and type D durometer “shore- D”. In addition,
type C for low hardness range is called ASKER and
GS-701N(G) is the same product ASKER-C. It complies
with hardness test of JIS S 6050 “Plastic eraser ”.
Furthermore, SRIS 0101 (ex Society of Rubber Industry,

JIS K 6301 was established in 1950 and had sustained base of rubber industry of
our country but was discontinued in 1998 because it did not comply with ISO andalso JIS K 6253 was prescribed on its behalf. However, It had been used for 60
years as “Rubber hardness tester” and even now it is used as test data between
certain parties in charge with mutual consensus although movement to new JIS
has progressed and standard is discontinued. There are 2 models such as Spring

Durometer Periodical Inspection and Calibration

Durometer is a testing machine. In case that it corresponds to “Monitoring Machine ” and “Measuring Machine” of ISO 9001 (JISG 9001), controlling machines along with it is needed. Teclock is one of a few manufacturers of durometer which has obtained
the authentication of ISO9001 and can originally issue 3 kinds of traceability system diagram, calibration certificate andinspection report that are needed for calibration documents. In addition, Teclock can issue 3 kinds of documents for durometer
tester and indenter height gauge, that are needed for internal inspection. Use these for control based on internal calibration
standard.

Precautions on use of Durometer
1.Confirmation of performance

Please confirm requested standard and type of durometeron the occasion of receiving. Please refer to the standard of
JIS K 6253, K 7215, K 6301, ISO 7619, ISO 868 and ASTM D
2240 in detail.

2. Test environment(1) Test environment for measuring samples is prescribed atinternal and external standard as " 23±2℃,humidity 50±
5%".
(2) please avoid using it where dust and oil mist attach to it.

3. Precaution on use(1) Check before using
1.Confirm whether operation is smooth.
2.Confirm whether accretion is on pressurized surface orindentor.
3.Confirm whether the indicator indicates "0 point".)(2) Never disassemble device and loose screws.
(3) Do not give the products any shock by being dropped orexcessive load.
(4) Keep the products away from direct sun light, excessivehigh or low temperature, and high humidity or dust. Avoid
using and storing the products under the circumstancesof water or oil.
(5) Do not press the products to hard samples like glassor metals excepting for the purpose of checkup andinspection.
(6) Do not clean with organic detergent ( thinner or benzine )and not put oil onto the products.
(7) Do not apply a load to the indentor in right angle. Do not
hit the products with a hard item.

(1) Indentor height : Indicator should indicate 0 on freecondition. Then it is checked whether indicator is in 100
by pressing pressurized surface onto hard and flat andsmooth surface. Meanwhile, be careful so that indentor
edge shape of Type D durometer is not changed.
(2) Indentor shape : It is checked by measuring microscope
whether dimension and shape of indentor edge is in
the permissible value of standard. In case that there isabrasion or damage , indentor needed to be changed.
(3) Spring force : It is checked by giving load against eachindicated value whether indicator correctly indicates.
Please use durometer tester "GS-607 series" to checkload of ● mark check point of 25, 50 and 75 on outer dial.
Permissible error of indicated value is ±1.

(2) In case that some sort of defect is observed for indicator,
indentor and spring load value by check up and repair or
adjustment is needed, please inform the sales outlet where
the products are bought. Products repaired or adjusted byparties not authorized by TECLOCK can not be warranted

“Duro” of Durometer means “hardness”
Durometers was launched as one of the devices from Shore the US measurement tools
company in the early years of the 1900. “Duro” comes from Latin, and means “hardness” as
etymologically same with “Duralumin” of aluminum alloy. The original device from Shore used
to be used as the Durometer standard, therefore Shore A is still remained as one of the
popularized names of Type A.
Since then, Durometers have been used in all over the world. In Japan, Durometers werecalled “Rubber Hardness Tester” in general. The primary durometers had scales counted bydouble width size than current durometers. Nowadays, the data of hardness is recognized ashigh importance issue. Therefore, the standard of durometers has been getting more stringent
than it used to be.
