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"
Shore AO: Low hardness of rubber and foam.
When using single pointer models, one should place the sample in the solid plane, hold the hardness gauge, keep the pressure needle at a distance of at least 12 mm from the edge of the sample, smooth enough pressure in the pressure on the sample, and smoothly press on the sample to a full extent. One should press the pressure needle vertically to the sample, and until pressed to a full extent and contact the sample completely, then read the calibration value within one second.
At measuring points which are at least 6 mm away from each other, measure hardness values for five times, and calculate the average value(for microporous material, the distance between the measuring points should be at least 15 mm). In order to keep the stability of conditions and improve the accuracy of determination, one should install the hardness gauge on the same type of the measuring shelf from a complete production network. When using double pointer models to do measurement, one should rotate the supporting pointer to the wax, etc.
