non-absorptiv

The k-value represents the required decay time to reduce the hydrogen peroxide vapor concentration measured at the beginning of the aeration phase to one tenth of the original concentration. The material classification is based on three separate measurements. The blank value of the test setup is subtracted from each measurement value.

The medium k-value is transferred to the following classification:
• ≤ 5 min: non-absorptive
• > 5 - ≤ 15 min: fast
• > 15 - ≤ 60 min: medium
• > 60 min: slow
• Not determinable: catalytic activity

The k-value can only be used to make a comparative material assessment. Provided the maximum hydrogen peroxide vapor concentration during material exposure is within the defined limit, it does not affect the calculated k-values.
