Shore Durometer Shore A durometer, Shore A hardness tester HS-A
HS-A durometer is an essential characteristic of various rubber, elastomers and plastic products.
It is feature portability, ease of operation, with facility, high resolution and it is available in GB/T 531 -1999 and ISO 7619, ASTM D2240.
Test range: 0-100 HA
Available test range: 10-90 HA
Stroke: 2.5 mm
Tip dimension: 0.79mm
Net weight: 0.2kg
Put the sample on a solid plane, hold the durometer to make the indenter at least 12mm away from the sample edge, and stably put the legs of durometer on the sample. Thus the indenter straightly goes into the sample till the legs completely get to the sample. Check the reading in 1s.Repeat such test 5 times at different place which are at least 6mm away from the test point and find the average reading (the distance between porous materials is at least 15mm).
Check to make sure before test that figure indicates zero (if not indicates zero, users may press “ZERO” key).When press the durometer on the glass plane, the figure should indicate 100 degree (the top of indenter and its legs should tightly touch the glass).If it does not indicates ZERO or 100 degree, slightly press the pointer several times; if there is still error, it is advisable to send it back to the manufacturer.
If it allows, rubber samples should be under the laboratory standard temperature. If the test result of the sample by A-type durometer goes beyond 90 degrees, it is advisable to use D-type durometer.When the test of the sample by D-type durometer goes below 20 degrees, it is advisable to use A-type durometer.If the figure on A-type durometer is below 10 degrees, it is incorrect and can’t be used.
When all the tests are over, users should clean the gauge, put it back into the box and keep it in a dry place.
