and check the chemical indicator color change; if the package is broken or torn, the load can
only be used immediately, in that preservation of sterility cannot be guaranteed.
The indicative times for preserving the material are shown below, considering that the material
itself is kept in closed cabinets away from light, heat and humidity.
Type of material
Suggested time (days)
Combination of paper-polypropylene
30 (single) – 60 (double)
Metal containers, with standard-grade filters
28/30
Medical Grade with double orthogonal layer
28/30
We emphasize the fact that the times indicated in the table above are indicative, in that the
preservation of sterility depends on numerous factors, as ambient microbic level, size of the
dust particles, ambient conditions of temperature, pressure and humidity, as well as the degree
of handling of the sterilized materials themselves.
The material should be stocked in sealed cabinets, 30 cm away from the floor and 5 cm from the
ceiling; if this is not possible protect the material in nylon bags.
