# The fungus test must be needed before installing cables or wires at long-running facilities or factories. If the fungus grows, the corona creepage or discharge should be occurred.
# This DATA is from MIL-STD-810G, METHOD 508.6.

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. |
