Standard Test Method for Effect of Household Chemicals on Clear and Pigmented Finishes. (Chemical Soak Test with Nine Test Solutions)
COATING SYSTEM:
PROTECTO 401 CERAMIC EPOXY Lining: Plant applied Protecto 401 lined ductile iron pipe (DIP) cut into 3 inch x 4 inch coupons.
TEST DURATION and CONDITIONS:
1080 hours (45 days), Room temperature, panels submerged 50% to provide liquid and vapor phase testing.
Coupons, cut from plant applied Protecto 401 Ceramic Epoxy lined pipe, were subjected to specific 1080 hour (45 day), 70 °C partial submersion in a series of strong chemicals. The test solutions and results are tabulated below.
