This standard specifies a method for the determination of the indentation hardness of plastics and ebonite by means of durometers of two types: type A is used for softer materials and type D for harder materials (see the Note in 8.2). The method permits measurement either of the initial indentation or of the indentation after a specified period of time, or both.
