resistance in automotive components): Equivalent of D2 (Note 2)
Note 1) A concrete testing method is to check for any adverse effect on the structure
after leaving it submerged for 30 minutes under 1 m of water (with
temperature difference between water and switch no larger than 5°C).
Note 2) A concrete testing method is to check for any adverse effect on the structure
after leaving it submerged for 10 minutes under 10 cm water (with
temperature difference between water and switch no larger than 30°C).
