The most probable number (MPN) bioburden test method can be a valuable tool for determining bioburden counts when the typical bioburden test methods are problematic on a particular product or when a ...

A new test method for elastomers and thermoplastic elastomers has been developed and now is standardized, according to ASTM 8363-20. The purpose of the TSSR test is to rapidly characterize those ...

My March column addressed flexural test methods for composite materials. I noted that the details presented in the various available national and international standards were not mutually consistent ...

A material’s hardness relates to its mechanical resistance when subjected to mechanical indentation by another harder body. Diamond is considered the hardest natural material and is typically used for ...

Until the mid-1970s, compression testing of composite materials received relatively little attention. Up to that point it, had generally been assumed that the compressive stiffness was approximately ...
