Certifications and testing

The T-Safe® filters have been tested in accordance to the bacterial retention protocol ASTM F838-05. This test was conducted by the international ISO 17025 accredited test laboratory Eurofins/Biolab in Italy. The ASTM F838-05 is the Standard Test Method for Determining Bacterial Retention of Membrane Filters Utilized for Liquid Filtration. The filters were tested with the following test organisms:

  • Brevundimonas diminuta
  • Legionella pneumophila
  • Pseudonomas aeruginosa
  • Aspergillus brasiliensis (spores)

The test showed a retention >7Logs thus validating liquid sterilization.

A field-test has been conducted by Statens Serum Institut (DK) on two Danish Hospitals – Herlev and Hillerød – validating the use of T-Safe® filter showers and Tap-Safe up to 92 days.

Hygiene-Institut des Ruhrgebiets in Germany further conducted a Legionella pneumophila bacteria retention test, validating the filter’s integrity throughout the service life of the filter.

Industrial Microbiological Services Ltd. (IMSL)  have tested the T-Safe® products in accordance to ISO 22196 for the products with Biomaster additive to validate the antibacterial activity.
