The ASTM E2197-17 standard developed by the American Society for Testing and Materials (ASTM) evaluates the ability of test substances to inactivate vegetative bacteria, viruses, fungi, mycobacteria and bacterial spores on hard, non-porous environmental surfaces and brushed stainless steel disc carriers representing medical devices. A test method for In addition, this standard is designed to have survivors compared to the average of at least three control carriers to determine whether the performance standard is met. For appropriate statistical evaluation of results, the number of viable organisms in the test vaccine must be high enough to account for both the standard of performance and experimental variation in results.
This test method does not involve any wiping or scrubbing. In addition, these tests should be performed by persons trained in microbiology in facilities designed and equipped to work with infectious agents at the appropriate biosafety level. It is the research assistant's responsibility to determine if Good Laboratory Practices (GLP) regulations are required and to follow them as appropriate.
With this test method, any loss of viable organisms by washing is eliminated and thus statistically valid data is obtained using far fewer test carriers than is required for simple predictive methods.
Firmness in the test is achieved by a soil load, microtopography of the brushed stainless steel carrier surface, and the ratio of the smaller test substance to surface area, which is typical for many disinfectant applications.
ÇA list of organisms frequently used in the evaluation of microbicidal activities of disinfectants for use on environmental surfaces or in medical devices is included in the annex to the standard. This appendix also includes culture conditions for each organism.
Our organization, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, within the scope of ASTM E2197-17 standard. It also provides standard quantitative disc carrier testing services to determine the bactericidal, virucidal, fungicidal, mycobactericidal and sporicidal activities of chemicals.
