EN 14476: 2013 + A2: 2019. Quantitative suspension test for the evaluation of virucidal activity in the medical area. Test method and requirements (Phase 2, step 1) under specific conditions for PT5 of BPR.

Test accredited by ENAC (Spanish National Accreditation Entity), for standard mandatory viruses and additionals.

Test with the certification of Good Laboratory Practices (GLPs).     

This test is performed according to EN 14476: 2013 + A2: 2019 standard adapted according to the specific conditions of the BPR Guidance. The test is performed with the mandatory viruses Adenovirus type5, Murine norovirus and Enterovirus (for example Coxsackievirus B4 or B5). The assay temperature is 15°C and the time of contact and the soling conditions depend on the intended use of the PT5 product, as indicated in the table below.

The product must be assayed at least at three concentrations, including one in the non-active concentration range and another in the active concentration range (these two last concentrations are selected by the testing laboratory). To consider the product as virucidal a 4 logarithmic reduction in the infectivity of viruses must be obtained.
