Okinawa Exposure Site Location

What is Outdoor Exposure Testing?

These are tests to investigate deterioration and changes on industrial materials and products by placing them outdoors.
We verify the effects of the natural environment including ultraviolet light, heat, rain, atmospheric gases, and salinity, and examine degradation over time.

UV, Solar Heat

Rain/Humidity

Atmospheric Gases

Paint Peeling

Red Rust

Paint Discoloration

Corrosive Environment

We know that the closer a test site gets to the ocean, the more sea salt particles adhere to parts.
Therefore, our exposure site is more susceptible to corrosion than other places.

Sea Salt Particles from the Ocean

What are sea salt particles?

These are particles made up of salt from the ocean & salt water lakes. They are formed by the evaporation of tiny water droplets when bubbles floating on the sea surface burst, and cause corrosion when they adhere to metal.

2/2020

Measurements started.

6/2020

Wind direction changed from NE to SE, resulting in slightly lower June/July levels.

During a typhoon, the volume of sea salt particles flying through the air is off the charts.

General Environmental Data

※Solar radiation data differs from the Meteorological Agency’s environmental data.
(This is due to different light detection areas resulting from measurements at a 30° angle.)
