ASKERDurometer Type B
ASKER
ASKER

The ASKER Durometer Type Bfor semi-rigid rubber (from normal hardness to high hardness), asspecified by ASTM D2240

It is used for measuring harder specimens, such as earthenwareclay or mossed pottery, than the Type A durometer, because theindentor is spring-loaded as in the ASKER Type A, but is a conicalshape as in the ASKER Type D.

Pressure foot
The Pressure foot in contact with the specimen is44mm in width and 18mm in depth, wide enough to ensure accuratemeasurement. The Longer Pressure Foot Type (Btype)is applicable for measurement of narrow or concavespecimens.

Our product line consists of varioustypes of durometers applicable to specific materials
as indicated in the chart above.

Type A Durometer (ASKER A type), conforming to JIS K 6235 is themost popular type of durometer for measuring rubber hardness.

However, verification is recommended because a significantdifference is estimated to be the largest when a durometerindicates measurement values from 10 to 90 points.

For hard specimens for which Type A Durometer readings indicatemore than 90 points, measurements should be undertaken using theType D Durometer (ASKER D type). However, for soft specimens withmeasurements of less than 20 points, the ASKER C type or Type EDurometer (ASKER E type) should be used. The most importantconsideration in using durometers is to select the correct type forpurposes of measurement according to the specimen.

ASKEROption
ASKER
ASKER ASKERTwo-pointer type (max-hand andactive hand) of Rubber Hardness Tester
The stationary set hand (max-hand) makes the maximum value easierto read and allows the creep characteristics of a specimen.

Accurate measurement is made possible for specimens* for whichstress relaxation occurs over time or for specimens for which it isdifficult to take readings from the front.

*Materials for which the reading decreases immediately after theindentor has been pressed against the surface.

ASKER ASKERConstant Loader forDurometer
·Constant loarder assures uniform test pressure eliminatingfalse readings due to differences between operators in measuring byhand.
·High accuracy and repeatability of the hardness readings areassured by the flexible joint function.
ASKER
ASKER ASKERIndentor ExtensionTester
·The gauge to check the indentor height on a durometer and thereading indicator mechanism.
·Inspection is conducted at 2, 50, and 100 pointsrespectively.
ASKER
ASKER ASKERLoad Tester forHardness Tester
·Tester to check load properties of the spring on a durometer
·Inspection is conducted at 2, 50, and 75 pointsrespectively.
