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 exposure. can be used: if the finished product will never come in contact with soil or tropical conditions, a much less severe test (e.g., 11 or 111) can be used. Test 11 is specifically designed for cellulose-containing materials while Test ill is for all others. For materials intended for outdoor and above ground use. Test IV can be used. The two important considerations when evaluating textile materials in relation to fungal growth are (I) the actual deterioration of the textile product (rot), and (2) growth not necessarily deteriorating the product, but making it unsightly (mildewy), often with an unpleasant and musty odor.
2.2 Certain pre-exposures of textile products may be needed when specific end-uses are critical (see Appendix A). When the end-use will be in high temperature environments and the fungicide niay be volatile, a preliminary oven exposure may be desired. When the end-use will be in tropical CXOSUCS or outside with rainfall present, a leaching exposure should be perthrmed before mildew evaluation is made. When at all possible, the textile material should be exposed to the expected conditions of use prior to performing this test.

5. Purpose and Scope
5.1 This procedure is used to evaluate the loss of strength of textile materials after exposure to soil and soil micro-organisms. This procedure is generally considered to be the most severe test for textile products. Only those specimens that will come in direct contact with soil-such as sandbags, tarpaulins, tents- need to be tested by this procedure. It can also be used for testing experimental textile fungicides.AATCC 30-2017e pdf download.
