ASTM D2240 durometers allow for a measurement of the initial hardness, or the indentation hardness after a given period of time. The basic test requires applying the force in a consistent manner, without shock, and measuring the hardness (depth of the indentation). If a timed hardness is desired, force is applied for the required time and then ...

It is the softest of the Tygon formulations with a durometer hardness of Shore A 40 (ASTM Method D2240-02). Because of the low durometer of this material it is often used in low-torque peristaltic pumps.

Indentation hardness tests compose the majority of processes used to determine material hardness, and can be divided into three classes: macro, micro and nanoindentation tests. [2] [3] Microindentation tests typically have forces less than 2 N (0.45 lb f). Hardness, however, cannot be considered to be a fundamental material property.

The Shikkui Surface Coatings have been tested in accordance with the ASTM International standards by accredited testing laboratories in the United States. • Fire Resistance (ASTM E84) Class A (Type I in other codes) • VOC Content (ASTM D3960) Zero-VOC material • Shore D Hardness (ASTM D2240) 61-85 (depending on product)
A neo-Hookean solid [1] [2] is a hyperelastic material model, similar to Hooke's law, that can be used for predicting the nonlinear stress–strain behavior of materials undergoing large deformations.
