Viral Penetration Testing

   Viral penetration test is a standard method under ANSI/AAMI PB70 to test the protective level of personal protective equipment (PPE) for medical purpose e.g. surgical gown, isolation gown and surgical drapes 

Test Method

ASTM F1670/F1670M-17a
Standard Test Method for Resistance of
Materials Used in
 Protective Clothing to
Penetration by Synthetic Blood

  • evaluate the synthetic blood resistance

  • according to ANSI/AAMI PB70 level 4

      (the highest level) of PPE e.g. surgical drapes
      and isolation gown

  • Screening test before the test of ASTM F1671/F1671M-13

ASTM F1671/F1671M-13
Standard Test Method for Resistance of Materials Used in Protective Clothing to Penetration by Blood-Borne Pathogens Using Ph-X174 Bacteriophage Penetration as a Test System 

  • evaluate the virus penetration resistance

  • according to ANSI/AAMI PB70 level 4
    (the highest level) of PPE e.g. 
    surgical gown and isolation gown
