ASKERDurometer Type E |
|
|
The ASKER Durometer Type Efor soft rubber (low hardness), as specified by JIS K 6253 and ISO7619. The application is the same as the standard ASKER Durometer TypeC
Widely used for measuring soft rubber, sponges, and other foamelastomers, as well as rolled-threads, -films and textile windings(yarn packages). |

Pressurefoot |
| The Pressure foot in contact with thespecimen is 44mm in width and 18mm in depth, wide enough to ensureaccurate measurement. The Longer Pressure Foot Type (EL type)is applicable for measurement of narrow or concavespecimens. |

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 the surface. |
