1. General Purpose and Scope
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.
2.2 Certain pre-exposures of textile
products may be indicated when specific
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.
3. Terminology
3.1 mildew resistance, n.—in textiles, resistance to development of unsightly fungal growths and accompanying un- pleasant, musty odors on textile materials exposed to conditions favoring such
growths.
3.2 rot resistance, n.—in textiles, re-
sistance to deterioration of a textile mate- rial as a result of fungal growth in or on it.
NOTE: Such deterioration is normally
assessed by measuring loss in tensile strength.
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.xposed
4.1 This test should be performed only
by trained personnel. The U.S. Depart-
ment of Health and Human Services pub-
lication Biosafety in Microbiological and Biomedical Laboratories should be con- sulted (see 24.1).
4.2 CAUTION: Some of the fungi used
in these tests are allergenic and patho- genic; i.e., capable of infecting humans and producing disease. Therefore, every necessary and reasonable precaution
must be taken to eliminate this risk to the laboratory personnel and to personnel in the associated environment. Wear protec- tive clothing, respiratory protection, and impervious gloves when working with
the organisms. NOTE: Choose respira-
tory protection that prevents penetration by the spores.
4.3 Good laboratory practices should
be followed. Wear safety glasses in all laboratory areas.
4.4 All chemicals should be handled
with care.
