| Curing Conditions: |
Set A - 14 days moist and 14 days dry |
|
Set B - 28 days moist |
| Test Requested: |
Freeze in air and thaw in water |
| Duration of Test: |
300 Cycles |
| Test Method: |
Conrad Freeze and Thaw Machine programmed to meet cabinet temperatures
as called for in the Freeze and Thaw Procedure B in ASTM C 666
71. |
| Average Durability Factor |
| (Based on 300 cycles) |
