Shore 000 Durometer Is Used to test Hardness of Ultra Soft Gels and
Sponge Rubber
- Overview
Shore dutometer conforms to standards ASTM D2240.
Shore 000 durometer is used to test hardness of Ultra soft gels and
sponge rubber..
Shore A: Soft rubber, plastics, and elastomers, printer's rolls
Shore D: Hard rubber and plastics such as thermo plastics, flooring
and bowling balls.
Shore B: Harder elastomers and plastics. Paper and fibrous
materials, Use above 93 Duro A.
Shore C: Medium hard elastomers and plastics. Also useful to avoid
surface marks.
Shore DO: Dense granular material, textile windings
Shore O: Very soft elastomers, textile windings, soft granular
materials. Use below 20 Duro A
Shore OO: Light foams, sponge rubber gels, animal tissue.
Shore M: Materials as thin as .050"

3.Operation instructions
Put the sample on a solid plane, hold the durometer to make the
pointer at least 12mm away from the sample edge, and stably put the
legs of durometer on the sample. Thus the pointer 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).
4.Notices
Check to make sure before test that the pointer points to zero(if
not indicates zero, users may turn the dial plate to regulate the
pointer to zero).When press the durometer on the glass plane, the
figure should indicate 100 degree(the top of pointer an 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 duorometer 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.
