According to the American Society of Testing and Materials (ASTM) F2100 standard, which specifies the performance requirements for materials used in medical face masks , five performance characteristics have been identified. These are particulate filtration efficiency (PFE), bacterial filtration efficiency (BFE), fluid resistance, differential. Mechanical testing specifications have been developed by the American Society for Testing and Materials (ASTM) and many of these specifications have been adopted by the American National Standards Institute (ANSI). Typically mechanical testing involves such attributes as hardness, strength, and impact toughness

4.1 The primary use of these test methods is testing to determine the specified mechanical properties of steel, stainless steel, and related alloy products for the evaluation of conformance of such products to a material specification under the jurisdiction of ASTM Committee A01 and its subcommittees as designated by a purchaser in a purchase order or contract Hardness Testing Basics. Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation. More simply put, when using a fixed force (load)* and a given indenter, the smaller the indentation, the harder the.
