Amount of growth | Grade | 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. |
