ASTM E2783-11 Standard Test Method for Evaluating Antimicrobial Activity for Water Miscible Compounds Using a Time Kill Procedure

ASTM E2783-11 Standard Test Method for Evaluating Antimicrobial Activity for Water Miscible Compounds Using a Time Kill Procedure

The ASTM E2783-11 standard, developed by the American Society for Testing and Materials (ASTM), provides a test method for determining changes in aerobic and anaerobic microorganism populations over a given sampling period when tested against in vitro antimicrobial test materials. The organisms used in this test method are standardized for growth requirements and inoculum preparation and must be grown under test conditions.

The primary purpose of this test method is to provide a set of standard conditions and test organisms to facilitate comparative evaluations of antimicrobial materials miscible in aqueous systems. This test method allows the option of using a test sample size of 10 mL or 100 mL. Knowledge of microbiological techniques is required to apply this test method. Meanwhile, aseptic technique must always be applied.

Briefly, the test method described in the ASTM E2783-11 standard is used to evaluate the in vitro reduction of the microbial population of test organisms after exposure to a test material.

Efficacy testing services performed in in vitro testing labs include biofilm prevention and removal, time killing kinetics, cleanroom disinfectant validation, inhibition zone and special efficacy studies for disinfectants, antimicrobials, and other products that require EPA registrations and FDA 510(K). In vitro laboratory studies are also performed to differentiate existing products in the market and to support unique marketing claims.

The suspension time killing test is preferred by topical germicidal product developers as it is a fast, relatively inexpensive and reproducible method to measure the biocidal potential of a liquid antimicrobial formulation. In this test method, the test substance is directly inoculated with a liquid containing a high concentration of test microorganisms, and then the percentage killed over time is determined. This test method is defined in the ASTM E2315 standard.

Among the numerous test, measurement, analysis and evaluation studies that our organization has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, standard test for the evaluation of antimicrobial activity for water-miscible compounds using a time-killing procedure within the scope of ASTM E2783-11 standard. also provides services.
