Test Package Request Form. This procedure must be carried out with bacterial species: Concentrations for all organisms and methods are done using automated equipment; as in Tempo Filler and Reader from BioMerieux and the Autoplater and Q-count from Spiral Biotech. Type of bacteria used: The choice of one or the other of the indicated inoculation methods depends on the properties of the surface of the textile product under test. All tests should include the test product with the antibacterial treatment, as well as a control tissue without antibacterial treatment supplied by the manufacturer.

In order to consider the result as significant, a reduction in the number of bacteria between 2 200743 3 logarithms must be obtained, considering a powerful activity if the value of the reduction is greater than 3 logarithms.

JIS L Determination of antibacterial activity of antibacterial finished

This implies the use of methods to corroborate the existence of antibacterial activity, applicable to textile products with antibacterial finishes, including fabrics, napas, threads and other materials for the manufacture of garments, bedding, domestic furniture and miscellaneous items, whatever the type of 220743 agent used organic, inorganic, natural or synthetic or any of the methods used by manufacturers for their incorporation into the textile product.

Determination of antibacterial activity of textile products. Staphylococcus aureus and Klebsiella pneumoniae.

Facebook Linkedin Instagram Twitter Google. The standard is applicable to all textile products, including cloth, wadding, thread and material for clothing, home furnishing and miscellaneous goods regardless of the type of antimicrobial agent used.

For the counting of the bacteria in the test products and in the controls, the conventional method of counting CFU colony forming units or the ATP-luminescence measuring can be used 200743 the amount of ATP in bacterial cells, expressed in moles of ATP-adenosine 220743.

For the method of inoculation by absorption, 0. Pseudomonas aeruginosa, Escherichia coli and methicillin resistant Staphylococcus aureus Test samples are run in triplicate and are sterilized by high pressure steam in the autoclave. Ecotoxicology – Test with algae, Daphnia magnaCrustaceans Palaemon spp.

ISO 20743 – Antimicrobial Textile Test

Inoculated samples are incubated for 18 hrs testing is run in triplicate for each organism and time point the bacteriostatic activity value and bactericidal activity value are calculated as log reductions JIS-L and ISO are very similar to AATCC This standard proposes three methods for inoculating the samples: Do not use Google Chrome Contact.

Isso client must choose, if desired, one or the other of the three inoculation methods indicated, as well as between the two detection methods indicated.

Initially, the ISO standard was introduced for the qualitative evaluation of antibacterial activity, for which quantitative methods such as those included in this standard had to be developed.
