Define the exposure before the material
Aggressive environments can include salt, chemicals, washdown, high humidity, dust, UV, temperature cycling, and corrosive gases. The enclosure material, coating, hardware, gaskets, cable entries, drainage, and maintenance plan must be considered together.
Inputs to collect
| Input | Why it matters |
|---|---|
| Chemical and salt exposure | Drives material, coating, and inspection choices |
| Water and washdown | Affects seams, drainage, gaskets, and cable entries |
| Temperature and UV | Influences finish, cooling, and service life |
| Internal heat and components | Sets ventilation or cooling requirements |
| Mounting and vibration | Determines mechanical and sealing details |
| Lifecycle and evidence | Aligns maintenance, spares, and product claims |
Scope boundary
Choose only from evidence applicable to the actual build and site. This guide does not guarantee corrosion life, ingress protection, or hazardous-area compliance.
