2.3.4. To study mechanical properties by hardness Test
Samples were prepared by 12 cm x 12 cm x 0.3 cm and
then hardness was tested by Durometer. Test for 5 point on the
sample and then find an average. Durometer is a hardness scale
based on the indentation hardness of a material. The Durometer
test determines the hardness by measuring the depth of
penetration of an indenter under a large load compared to the
penetration made by a preload.
