Standard / test method

DIN EN ISO 20743

Testing of the antibacterial activity of textile products in accordance with DIN EN ISO 20743.

Overview

DIN EN ISO 20743 specifies standardised test methods for the quantitative determination of the antibacterial activity of textile products.

The methods are suitable for textiles with antibacterial treatments and enable comparison with an untreated reference material.

Typical test organisms are Staphylococcus aureus and Klebsiella pneumoniae. Antibacterial activity is evaluated quantitatively by comparing the results obtained for the treated textile with those obtained for an untreated reference material after a defined contact time.

Testing can be adapted to the project according to your testing objective, sample type, sample size, contact time or requested test strains.

Typical applications

Antibacterial textiles

Assessment of textile products with antibacterial finishes or functional treatments.

Product development

Comparison of new textile materials and finishes in terms of their antibacterial properties.

Material qualification

Quantitative testing of antibacterial activity in technical and application-specific textiles.

Frequently asked questions

Which products is DIN EN ISO 20743 suitable for?

DIN EN ISO 20743 is suitable for textile products with antibacterial treatments, including treated fabrics, fibres, textile sheet materials and technical textiles.

Which bacteria are used in DIN EN ISO 20743 testing?

Typical test organisms are Staphylococcus aureus and Klebsiella pneumoniae. Additional test organisms can be considered for specific projects.

How is antibacterial activity evaluated?

Antibacterial activity is evaluated quantitatively by comparing the results obtained for the treated textile with those obtained for an untreated reference material.

What is the difference between DIN EN ISO 20743 and JIS L 1902?

DIN EN ISO 20743 and JIS L 1902 are closely related methods for determining the antibacterial activity of textile products. The appropriate test depends, among other factors, on specifications for the target market and the client's requirements.
