Hardness

ARDL regularly provides durometer and IRHD testing according to specified methods or customer requirements using hand held and stationary equipment to penetrate a material with a special indentor. The durometer of the material is then recorded after a specified amount of time. This testing can assist customers with determining the durometer across a surface and to ensure that the material meets a specified hardness range.
