Testing ASTM standards

Standard test methods for measuring adhesion by tape test, ASTM Standard ASTM D3359-09, ASTM International, WestConshohocken, PA, 2009. 

Laboratory tests to determine shear strength are the direct shear test, the unconfined compression test, and the triaxial test. ASTM Standards give complete details of these tests. Triaxial tests yield the most reliable results. The manner in which these tests define the failure line as shown in Figure 2.4.

Secure adhesion of the CP film on a substrate is another important mechanical property for long-term function of a bioimplant device. Pull-off tests (ASTM standard procedure D-4541-95) and other ASTM adhesion and hardness assays may provide valuable information on the adherence of CP films to metal substrates [1,137].

The subjection of a material to standard environmental and/or stress history before testing, so that it will respond in a uniform way to subsequent testing or processing. The term is frequently used to refer to the treatment given before testing. ASTM standard conditions for a plastic testing laboratory are 23 2 °C and 50 + 5 % relative humidity.

Because hardness is easy to measure and indicative of many performance capabilities, hardness is typically used as a quality conformance test. ASTM standards C-661 and D-2240 govern hardness measurements.
