ASTM F1855-00(2019)

Anotace textu normy ASTM F1855-00(2019) :

This specification covers polyoxymethylene (acetal) resin for medical applications. This specification provides requirements and associated test methods for a form of this thermoplastic which is intended for use in manufacturing medical devices, instrumentation or components thereof. Physical and mechanical properties of medical grade polyoxymethylene such as specific gravity, water absorption, equilibrium, tensile yield strength, tensile elongation break, tensile modulus, tensile impact strength, compressive strength, and sheer strength shall be determined. Biocompatibility of acetal resins and implant devices made using these materials shall also be determined.
