Shore a hardness unit of measure

For measuring Shore A the foot indents the material while for Shore D the foot penetrates the surface of the material. Material for testing needs to be in laboratory climate storage at least one hour before testing. Measuring time is 15s. Force is 1 kg +0.1 kg for Shore A, and 5 kg +0.5 kg for Shore D.
