ASTM E2275 is a standard practice for evaluating water-miscible metalworking fluid bioresistance and antimicrobial preservative performance. Metal Working Fluids (MWF) are regularly used in challenging environments and are often exposed to significant microbial populations. Untreated or untested, MWF’s ability to function properly can be compromised by microbial contamination.  ASTM E2275 is also used to determine the overall […]

ISO 11348 is the standard method for the determination of the inhibitory effect of water samples on the light emission of Vibrio fischeri. ISO 11348 determines the inhibition of the luminescence emitted by the marine bacterium Vibrio fischeri (  This method is applicable to: waste water aqueous extracts and leachates fresh water (surface and ground water) sea and brackish […]

ISO 11348: Water Quality Luminescent Bacteria Test

ISO 20743 is a standard antimicrobial test method that determines the antibacterial activity of antibacterial- finished textile products. Standard organisms tested against for ISO 20743 include S. aureus and K. pneumoniae; other organisms may be used by customer request. Depending on the intended use of the product, different testing options can be selected to determine […]

ISO 20743 – Antimicrobial Textile Test

ISO 22196 is an antimicrobial surface test that performs the measurement of antibacterial activity on plastics and other non-porous surfaces. Based on the JIS Z 2801, ISO 22196 is a surface test generally used with standard bacteria that can be substituted depending on the needs of the customer. The standard ISO 22196 test method is […]

ISO 22196 – Antimicrobial Plastic Test

ISO 846 evaluates the effects and propagation of bacteria on plastic materials that are exposed to the environment. The 4 options for ISO 846 (A, B, C, and D) include tests for fungi, bacteria separately and in the mixed inoculum. The ISO 846 test method is often used for plastic exposed to the environment but […]
