What to verify
- 01
Distance from saltwater and chloride exposure
Ask for the exact evidence, applicable configuration, limits and responsible party. Avoid accepting a headline claim without its conditions.

Evidence before claims
For project products, a useful answer names the model or system, the tested or documented configuration, the operating conditions, exclusions and who is responsible for local engineering or installation. Requirements vary by destination and project.
Use this guide for early project planning and technical review. Project-specific engineering, code review and professional installation requirements should be confirmed for the destination.
