AATCC 28:2004 pdf download.Insect Pest Deterrents on Textiles
1.1 This test method covers procedures for the evaluation of compounds or treat- ments designed to protect textile fabrics and yarns from damage by insect pests, such as moths or carpet beetles. They comprehend not only the initial protec- tion furnished by the treatment, but also the permanency of the protection during conditions of ordinary service.
2. Principle
2.1 Treated and untreated specimens are subjected to the action of insect pests under controlled conditions for one expo- sure period and then examined for evi- dence of damage. Additional exposure periods are given as necessary until vi- sual damage is evident.
4. Safety Precautions
NOTE: These safety statements are for information purposes only. The precau- tions are ancillary to the testing proce- dures and are not intended to be all inclu- sive. It is the user’s responsibility to use safe and proper techniques in handling materials in this test method. Manufac- turers MUST be consulted for specific details such as material safety data sheets and other manufacturer’s recommenda- tions. All OSHA standards and rules must be consulted and followed.
4.1 Good laboratory practices should be followed. Wear safety glasses in all laboratory areas.
4.2 All chemicals should be handled with care. Use chemical goggles or face shield, impervious gloves and an imper- vious apron during dispensing and mix- ing of the chemicals used in this test method.
6.1 Test specimens are prepared by ap- plying the treatment or compound to be tested in the desired proportion to a piece of standard pure undyed scoured wool (see 18.1). After application, the speci- men is thoroughly aired for a period of not less than 7 days for the removal of all volatile constituents. The size of the piece should be sufficient to furnish specimens for all of the service tests to which it is to be subjected.
6.2 If it is desired to determine the re- sistance of the treatment on a special fab- ric, test specimens are prepared as de- scribed in 6.1 using the special fabric instead of the standard fabric.AATCC 28 pdf download.
