Physical Testing Methods

Physical Testing Benefits:

Impact Testing (IMP):

General Information

Impact testing was performed on an Instron Dynatup 9250HV.  The ASTM D3763 method was followed using the following parameters: striker diameter (0.5 in or 12.7 mm), striker weight (~26 lb or ~11.8 kg), striker drop height (1.92 ft or 0.59 m) impact velocity (10.9 ft/sec or 3.3 m/s), impact energy (~46 ft lbf or ~62 J) and testing temperature (77°F or 25°C).

Density or Specific Gravity (DEN):

The density of components or sample specimens is measured using a balance apparatus based on ASTM D 792. The density testing was performed using a Mettler Toledo XS105 scale and the manufacturer provided density apparatus.

Hardness Testing

Rockwell Hardness:

The hardness was measured using the Instron Wilson Rockwell 2000B.  The hardness measurements were taken on the prepared cross-section using the listed Rockwell Scales using the method, ASTM E18.  The hardness measurements if necessary may be converted to another hardness scale such as Brinell (HBS) hardness scale using the specification, ASTM E140.

Durometer Hardness (Rubber Property):

The hardness was measured using the Type A Durometer or Type D Durometer.  The hardness measurements were taken on the available plane surfaces of the submitted material samples.  The hardness testing was based on two test methods, ASTM D2240 and ISO 868.  The measurement values are provided for the maximum gauge reading and the reading after the interval of fifteen seconds.
