The TH Series Freeze/Thaw Chambers accommodate testing standards specifically designed for assessing the durability of materials under cyclic temperature conditions:
AASHTO T103 Test Method: This standard involves three different procedures (A, B, and C) that test the freeze-thaw resistance of concrete specimens to evaluate their durability.
Procedure A: This procedure tests the specimen's resistance to freezing and thawing while submerged in water.
Procedure B: In this procedure, the specimen undergoes freeze/thaw cycles while submerged in a sodium chloride solution, providing insights into the effects of deicing chemicals.
Procedure C: This method involves testing the specimen's resistance to freeze/thaw cycles in an air environment, mimicking conditions where water ingress and subsequent freezing could occur within air pockets.
Iowa Department of Transportation Test Method 211-B: This method is used to assess the freeze and thaw durability in hydraulic cement concrete, particularly focusing on transportation-related infrastructure.
These standards ensure that materials meet the necessary durability and safety requirements under variable temperature conditions.
