ASKERDurometer Type F |
|
|
The ASKER Durometer Type Ffor much softer specimens (low hardness) gives accurate readings asit features a larger indentor and pressurefoot.
The durometer exclusively for various foam materials such asurethane foam, sponge, etc.
There is no need to press the durometer into the specimen, butjust to place it onto the specimen. As it is soft, the weight ofthe durometer constitutes the pressure to the specimen. |

Hardness TesterSelection Chart | | | 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. |

| Option |
|
| | | | Two-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 thesurface |
