EN 1275 Basic Fungicidal Activity

Test Purpose
The European standard, EN 1275, describes a suspension-based, quantitative, microbiology lab test for establishing the capability of a client’s product to produce a reduction in the number of viable fungal cells under conditions defined by the standard.

Test Summary
A test suspension of fungal cells is added to a prepared sample of the test substance diluted with sterile deionized water. At the Sponsor specified contact time, an aliquot is taken and the fungicidal and/or fungistatic activity is immediately suppressed by dilution or filtration neutralization. The number of surviving fungi in each sample is determined standard culture plating techniques and the reduction in viable counts is calculated.
