1. Purpose and Scope
1.1 This test method provides a quantitative procedure for the evaluation of the degree of antibacterial activity. Assessment of antibacterial finishes on textile materials is determined by the degree of antibacterial activity intended in the use of such materials. If only bacteriostatic activity (inhibition of multiplication) is intended, a qualitative procedure which clearly demonstrates antibacterial activity as contrasted with lack of such activity by an untreated specimen may be acceptable. However, if bactericidal activity is intended or implied, quantitative evaluation is necessary. Quantitative evaluation also provides a clearer picture for possible uses of such treated textile materials.
2. Principle
2.1 This test method provides a quantitative procedure for the comparison and evaluation of the degree of antibacterial activity after a 24 h exposure to the test bacteria on the test fabric compared directly against an untreated control. After incubation, the bacterial challenge is eluted from the swatches and enumerated and a percent reduction by the fabric specimen is calculated.
3. Terminology
3. 1 activity, n.—o[ an aiitibacterial agent, a measure of effectiveness of the agent.
3.2 antibacterial agent, n.—in textiles, any chemical which kills bacteria (bactericide) or interferes with the multiplication. growth or activity of bacteria (bacteriostat).
4. Safety Precautions
4.1 The safety precautions specified in the method are ancillary to the testing procedures and are not intended to be all inclusive.
4.2 It is the user’s responsibility to reference applicable safety data sheets, use safe and proper techniques. and wear appropriate personal protective equipment in handling materials in this standard.
4.3 Users MUST be consult manufacturers br specific details such as safety data sheets, equipment operating instructions, and other recommendations. Con- suit and follow all applicable health and safety regulations (e.g.. OSHA standards and rules).AATCC TM100 pdf download.
