ASTM E1053 : 2011 – Standard to Assess Virucidal Activity of Chemicals Intended for Disinfection of Inanimate and Nonporous environmental surfaces
ASTM E1053 is a surface test to determine virucidal activity of chemicals intended for the disinfection of inanimate and nonporous environmental surfaces. Products to be evaluated for virucidal efficacy using ASTM E1053 include liquid, aerosol, or trigger-spray microbicides.
ASTM E1053 test can be performed for most viruses that are grown and multiply on cell cultures. Additionally, this test can be used for other virus cultivation mediums such as embryonated egg culture.
ASTM E1053 Test Conditions & Requirements
- Test temperature – 22 ± 2 °C
- Contact time – As suggested by manufacturer
- Interfering substance – Fetal bovine serum or organic soil load
- Log reduction – For a product to pass virucidal efficacy criteria, it must achieve 4.8 log reduction value.
ASTM E1053 Test Method
- Viral suspension is uniformly spread over the surface of separate (size of 100 × 15 mm) glass petri dishes.
- On dried virus film, test sample is inoculated and maintained at 20°C for desired contact time. Meanwhile, in test control, the sample is replaced with an equal amount of buffer solution.
- The inoculated surfaces of the plates are scraped and passed through Sephadex gel filtration column to determine the titre of the remaining virus.
- This filterate is further diluted and plated to determine infectious titre.
