In addition to the guidance provided in Part One, paragraphs 5.14 and 5.17, the following information is provided to assist in the evaluation of the test results. Apply any data relative to failure of a test item to meet the requirements of the materiel specifications to the test analysis, and consider related information such as:
- a. Any fungal growth on the test item must be analyzed to determine the species.
- b. Any fungal growth on the test item material(s), whether from the inoculum or other sources, must be evaluated by qualified personnel for:
- (1) The extent of growth on susceptible components or materials. Use Table 508.8-II as a guide for this evaluation, but any growth must be completely described.
MIL-STD-810H
METHOD 508.8
- (2) The immediate effect such as discoloration or other visual degradation that the growth has on the physical characteristics of the materiel.
- (3) The long-range effect that the growth could have on the materiel (possible storage issues if degradation is noted).
- c. Evaluate human factors effects (paragraph 2.1.1.3).
- d. Cleaning solution used if other than water.
| AMOUNT OF GROWTH | RATING | COMMENTS |
|---|---|---|
| None | 0 | Substrate is devoid of microbial growth. |
| Trace | 1 | Scattered, sparse or very restricted microbial growth. |
| Light | 2 | Intermittent infestations or loosely spread microbial colonies on substrate surface. Includes continuous filamentous growth extending over the entire surface, but underlying surfaces are still visible. |
| Medium | 3 | Substantial amount of microbial growth. Substrate may exhibit visible structural change. |
| Heavy | 4 | Massive microbial growth. |
