The main failure modes caused by mold:
1. Microorganisms digest organic materials during normal metabolic processes, thereby degrading substrates, reducing surface tension, and increasing the penetration of moisture;
2. Enzymes and organic acids produced during metabolism can cause metal corrosion, glass etching, oil hardening, and other physical and chemical changes in matrix materials.
3. Microorganisms form a bioelectric bridge between components, which may cause circuit failures.

Service Background
Mold is a widely distributed microorganism in nature, widely present in soil and air. Mold testing is a project in climate and environmental testing, used to assess the ability of products or materials to resist mold erosion. Like general environmental testing, it selects participants in actual transportation
