ASTM E2011-21. Standard Test Method for Evaluation of Hygienic Handwash and Handrub Formulations for Virus- Eliminating Activity Using the Entire Hand.
Test accredited by ENAC (Spanish National Accreditation Entity).
Test with the Certificate of Good Laboratory Practices (GLPs).
This test is designed to evaluate the ability of products for hand washing or hand rub to reduce or eliminate people's skin viruses. This test performs full hand exposure and reflects the actual conditions of use, such as handrub during manual decontamination, and also allows alternative products such as alcohol-based or non-alcohol based liquids, gels and foams to be tested according to the manufacturer instructions. Both hands, including the nail beds, of the participating subjects are exposed to high-titer virus suspensions. The test is performed with a minimum of six subjects for each combination of test substance and virus to be evaluated. Some of the following viruses may be used in the test: type 2 or type 5 Adenovirus, Hepatitis A virus, Murine Norovirus, Rhinovirus, Rotavirus and/or Feline Calicivirus. The exposure time of the test substance must be a representative time to the actual conditions of use, 10 to 20 seconds for a hand soap and 20 to 30 seconds for a hand sanitizer. The test uses an interfering substance, consisting of fetal bovine serum at a final concentration of 5%. In our laboratory, the test is performed including the controls indicated by the ASTM E2011-13 standard and by the UNE-EN 14476: 2014 + A1 2015 standard. The customer must choose a contact time and a test concentration or manufacturer's instructions on how to add the product. The applicant for the test must record these requirements on the test form.
