(40 +1/-0 wipes per roll; 100% polyester; grammage > 45 g/m 2 )
Test product: terralin PAA (1% and 2% working solution)
Test design
The schülke wipes mini-system was in each case filled with 3 litres of the different terralin
PAA working solutions (1% and 2%). To determine the concentration of the respective test
samples, the working solution was pressed out of the wipe rolls after predefined standing
times of 6, 8 and 12 hours and the concentration of peracetic acid was determined for these
standing times.
Results
Usability of terralin PAA
in the schülke wipes mini-system
Analysis of the tested 1% and 2% working solutions of terralin PAA in the schülke wipes
mini-system revealed an adequate active-substance concentration of at least 90 ± 5% for
both strengths at a storage temperature of 25 ± 2 o C. The disinfection performance of the

tested working solutions in the schülke wipes mini-system is thus fully assured in connection
with standing times encountered during the working day.
Summary
In this test we were able to show that the investigated working solutions of terralin PAA are
suitable for use in the schülke wipes mini-system in connection with standing times
encountered during the working day and that disinfection is fully assured when the product is
used correctly.
Thus terralin PAA is well suited for self-filling of the schülke wipes mini-system by the user.
In order to ensure that the surfaces to be treated are adequately wetted, it is recommended
that 3 litres of working solution is used per roll of 40 +1/-0 wipes.
The hygiene requirements concerning the production and storage of disinfection solutions
are to be observed. The water and vessels used for producing the disinfection solution
should be in a satisfactory state of hygiene.
This recommendation will not apply if any modifications have been made to the products
mentioned above.
