work piece arecohered each other, the indentor changes shape ofwork piece by pressurized force caused by spring of
durometer and work piece makes force against thisforce. Force amount of indentor is indicated as
hardness when this pressurized force and repulsive
force are equivalent.
If repulsive force is weak, it shows low value (soft), on
the contrary, if repulsive force is strong, it shows highvalue (hard). There are various type of durometers ofwhich force of springs and shape of indentors aredifferent. The reason why there are various kinds ofdurometers, it is for the purpose of showing degree of
hardness with higher sensitivity against difference ofmaterial characteristics and shape of surface which
work pieces have. Select a suitable product referringto the figure in the right.

Hard material

Model Selection of Durometer

Soft material

Durometers show the degree of hardness by value whether a non-rigid material like rubber is soft or hard (hardness gauge for rubber or plastic).
Recently, JIS standard and ISO standard have been drastically revised and details of hardness tester of rubber and method of measuringhardness are changed.
As an all embracing manufacturer of non-rigid material hardness tester, Teclock proposes lots of measuring methods of measuring hardness of
not only rubber and plastic but many non-rigid materials and elastic materials.

Measuring hardness with Durometer

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

58

In order to solve individual difference ofmeasured value, it is clearly mentioned in
the standard to measure hardness bymounting durometer to stand.

1. In case of measuring by pushing by hand, putting pressurized
surface of durometer held by hand from the top vertically with acertain speed to the flat face of work piece which is put on the flatface . Then, after adhering it, regard the value measured within thepassed time prescribed by standard as “hardness”.
2. In case of measuring hardness by mounting durometer to stand,measuring speed (not more than 3.2mm/sec.), pressurized load(type A, E is 1kgf, type D is 5kgf) and pressurized surface diameter(φ18mm) of type A / D durometers including tolerance arestandardized.
3. Measuring point of test piece is to be inside from its edge by 12mm
or more and clearance is to be 6mm and more. Thickness isnormally 6mm and more, and 10mm and more for type E.
4. Test environment : Temperature is 23℃±2, humidity is 50±5% andmedian or average is applied for measured value. If 50 show in type
A case, it is described［A50］.
These are ruled for each standard.

Compliance with JIS K 6253 standard

AnalogNew JIS compliance

DigitalISO compliancefor Hardness test of vulcanized or thermoplastic rubberThis is Durometer to comply with JIS K 6253 (new JIS) standard established in 1993 for the purpose of conforming to ISO (International Standard
Organization). Durometrers consist of 3 types namely, Type A for medium hardness, Type D for high hardness and Type E for low hardness.
Type A tends to indicates higher value by 1~2 points compared with former Type A durometers. Type D is suitable for hard rubber having morethan 90 hardness measured by type A durometer and Type E is suitable for soft rubber of which hardness is 20 and below measured by Type A
durometers.

Standard Type
Digital Durometer with Peak Hold Function

This is the model for which peak hold (Maximum value is held)
function is mounted.
This is effective to measure hardness of Elastomer of which
maximum value is unreadable due to relaxation phenomenon.
Minimum read value is o.5 and it is a half of analog type.
Measured data can be treated as statistics by connecting with
optional printer SD-763P.

Some of Rubbers, Elastomer' elastic body is not easily read the maximum value after firm contactingwith a presser foot of durometer , due to the stress relaxation. The pointer indicates the descendent
value but the peak pointer is holding the maximum measured value. The peak pointer type 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 from peak pointer after
measuring. The upper / lower limiters equipped will be effectively used in tolerance judgment.

Deep Hole / Long Leg Type

AnalogDigital

In some cases, such as the measurement surface of uneven or with a narrow flat area and the bottom of deep hollow, it may be impossible toachieve the proper results because of the difficult contact of the presser foot. The Deep Hole (H) type and the Long Leg (L) type make suchmeasurements possible with a small or long presser foot. Both are supplied with Peak Pointer and the upper/lower limiters. The Long Leg typemeets also to DIN 53505 standard.

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

Durometer Tetster

This is inspection machine which simply checks spring load value of analog type durometer. Putting definedload with 3 pieces of standard weight to the inverted durometer and inspecting whether graduation of 25,
50 and 75 correctly point out. Calibration certificate can be issued. (Digital type durometer and other makes
products can not be calibrated.)
In addition, in the standard of overseas and also domestic, inspection method by using mechanism of evenbalance and with normal position of durometer is introduced.

Nomenclature

1.Confirmation of performance

Durometer

Please confirm requested standard and type of durometer on 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 at internal 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

Adapter

Pointer
Dial
Peak PointerCheck Point(1) Check before using
Base① Confirm whether operation is smooth.
② Confirm whether accretion is on pressurized surface or indentor.
Indentor③ 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 or excessive load.
(4) Keep the products away from direct sun light, excessive high or low temperature, and high humidity or dust. Avoid using and storing the
products under the circumstances of water or oil.
(5) Do not press the products to hard samples like glass or metals excepting for the purpose of checkup and inspection.
(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.

4. Maintenance(1) In case that outer dial can not be read due to dirt of crystal, please wipe stains from the crystal by using a dry cloth or a cloth dampened
with neutral detergent.
(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 by parties not authorized by TECLOCK can not
be warranted by us.

5.Periodical inspection

Durometers are needed to be inspected during a certain period, which depends on usage frequency. Especially, in case that instruments arecontrolled by "inspection, measuring and test instruments " of ISO 9000 series, it is important element.
(1)Indentor height : Indicator should indicate 0 on free condition. Then it is checked whether indicator is in 100 by pressing pressurized surface
onto hard and flat and smooth 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 ofstandard. In case that there is abrasion or damage , indentor needed to be changed.
(3)Spring force : It is checked by giving load against each indicated value whether indicator correctly indicates. Please use durometer tester"GS-607 series" to check load of ● mark check point of 25, 50 and 75 on outer dial. Permissible error of indicated value is ± 1.
