The ASTM E2011-21 standard, published by the American Society for Testing and Materials (ASTM), defines a test method for evaluating hand washes or hand rubs for their ability to reduce viral contamination from hands. Knowledge of virological techniques is required for this test method.
With the test method described in the ASTM E2011-21 standard, virucidal activity for both handwash and handrub formulations is determined by comparing the reduction in virus infectivity from hands treated with a test article to hands treated with a control article. This test method is similar to the test method described in the ASTM E1838 standard (ASTM E1838-17 Standard test method for determining the virus-removing effectiveness of hygienic hand washes and hand rubs using the fingertips of adults).
If any product is not found suitable for testing with the ASTM E2011-21 standard, then the ASTM E1838-17 test method is applied as an alternative test method.
The ASTM E2011-21 test method is performed on healthy individuals with undamaged skin on their hands and lower arms. These individuals avoid using antimicrobial products for at least one week before the test. Immediately before testing, subjects' hands are washed for one minute with a mild, non-antimicrobial soap and then dried. To reduce the possibility of cell culture assay contamination while test samples are plated for evaluation, the hands are then decontaminated with ethanol and optionally rinsed with sterile water to remove any ethanol residue. A suspension of the selected test virus is prepared and spread evenly over all surfaces of the subjects' hands, then left to dry. When evaluating handwash formulations, the subject's hands are moistened with water after viral inoculation. The hands are then treated with conditions that reflect real-world usage conditions. Then the subject's hands are rinsed and the sample is taken.
Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, provides hygienic hand wash and hand rub formulations for virus eradication activity by using the whole hand within the scope of ASTM E2011-21 standard. It also provides standard testing services for evaluation.
