INSTRUCTION MANUAL
PARTS IDENTIFICATION
TEST SAMPLES
SPECIFICATIONS
・Hardness test for rubber and plastic.
APPLICATIONS
This product is compliant with the following
standards with regards to Indenter shape, size,
dimensions, and spring force.
JIS K 6253
『Rubber, vulcanized or thermoplastic - Determination
of hardness』
ISO 7619(E)
『Rubber-Determination of indentation hardness by
means of pocket hardness meters』
STANDARDS
・This product is to be used as Hardness Measuring Instrument for
plastic and rubber. Please use only as directed.
・Only use within applicable measuring range for each model. Use
beyond specified range may cause errors or damage to instrument.
・Never press indenter against hard surface, such as glass or metal,
with the exception of testing using the Wear Test Block.
・Do not apply force greater than 2-3 times force specified by the
relevant standards (JIS, ASTM, ISO, DIN, etc.)Excessive force
may affect accuracy and cause damage to the instrument.
・Do not apply lateral pressure or move the indenter when in contact
with test sample.
・Instrument is designed for using in vertical orientation with
downward pressure. Use in horizontal or upward direction will result
in inaccurate measurements.
・Please Note – Measurements taken by this instrument will vary
from those taken using a different measurement standard, such as
JIS K6301, etc.
・This is a precision measurement instrument, Do not drop or apply
excessive force as it may result in inaccuracy.
・Do not use in wet or oily locations.
・Do not disassemble or modify.
・Do not use organic solvents (thinner, benzine, etc.)to clean.
Please insure that Test Samples meet the following conditions.
・Top and bottom surfaces should be smooth and parallel.
・Sample is free from scratches, air bubbles, and contamination.
・Sample meets the size conditions below:

Measurement
Points (5x)
①Loosen the Dial Locking Screw and rotate the Bezel to align the
Pointer with “0”. Re-tighten the Dial Locking Screw.
②Place the test sample on a flat, rigid surface.
③Determine the locations for applying the indenter for test.
Locations should satisfy the two conditions below: (Figure:1)
(1)More than 12mm from edge of test sample. (ADM-A、ADM-D)
More than 15mm from edge of test sample. (ADM-E)
(2) Separated by at least 6mm from adjacent measurement points.
④Hold the Durometer so that the two conditions below are
satisfied: (Figure:2)
(1)The Pressure Plate is parallel to test surface.
(2)The indenter body is perpendicular to test surface.
⑤Without causing shock, gradually press the indenter into the
surface until the Pressure Plate is against the surface of he test
piece.
⑥When the Pressure Plate is in contact with the surface, wait
following period before taking a reading:
・Vulcanized rubber: after 3 seconds
・Thermoplastic rubber: after 15 seconds
⑦Measurement is median value of the five measurement values
taken at different locations
※“Median”is determined by arranging values in ascending order,
and the median is the value in the center.
HOW TO USE
①Loosen the Dial Locking Screw and rotate the Bezel to align the
Pointer with “0”. Re-tighten the Dial Locking Screw.
②Rotate the Follower Knob counterclockwise, moving the
Follower to the right hand side of the Pointer. (Figure:3)
③Take measurement. Maximum position of pointer will be records
by the Pointer Follower.
USING THE POINTER FOLLOWER
With continued use, the indenter will wear. Check the wear
regularly using the following procedure and take the extent of wear
into account when taking measurements.
①Loosen the Dial Locking Screw and rotate the Bezel to align the
Pointer with “0”. Re-tighten the Dial Locking Screw.
②Place the supplied Wear Test Block on a flat, rigid surface
③Put the indenter into the test hole and press gradually to avoid
damage to the Wear Test Block. The gauge will read the
number indicated below for indenter with no wear.
※If indenter is worn, a lower number than specified will be indicated.
