1.1 The two purposes of this test method are to determine the susceptibil- ity of textile materials to mildew and rot and to evaluate the efficacy of fungicides on textile materials.
2. Principle
2.1 Tests I, II, III and IV can be used, singly or in combination, depending on the type of exposure to which the textile material will be subjected. For example, if the final product will come in contact with soil, Test I, which simulates this ex- posure, should be used; if the finished product will never come in contact with soil or tropical conditions, a much less severe test (e.g., II or III) should be used. Test II is specifically designed for cellu- lose-containing materials while Test III is for all others. For all materials intended for outdoor and above ground use, Test IV should be used. The two important considerations when evaluating textile materials in relation to fungal growth are (1) the actual deterioration of the textile product (rot), and (2) growth not neces- sarily deteriorating the product but mak- ing it unsightly (mildewy) often with an unpleasant and musty odor. products may be indicated when specific 2.2 Certain pre-exposures of textile end-uses are critical (see Appendix A). When the end-use will be near high tem- perature and the fungicide may be vola- tile, a preliminary oven exposure may be desired. When the end-use will be in tropical exposures or outside with rainfall present, a leaching exposure should be performed before mildew evaluation is made. When at all possible, the textile material should be exposed to the ex- pected conditions of use prior to perform- ing this test.
4. Safety Precautions NOTE: These safety precautions are for information purposes only. The pre- cautions 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 also be consulted and followed.AATCC 30 pdf download.
