Shore durometer R designation also mandates the employment of an operating stand. Some conditions and procedures that have to be met, according to DIN ISO 7619-1 standard are: The final value of the hardness depends on the depth of the indenter after it has been applied for 15 seconds on the material. If the indenter penetrates 2.54 mm (0.100 inch) or more into the material, the durometer is 0 for that scale. If it does not penetrate at all, then the durometer is 100 for that scale. It is for this reason that multiple scales exist. But if the hardness is <10
