ASTM WK83234
Revision of C67/C67M-21 Standard Test Methods for Sampling and Testing Brick and Structural Clay Tile
Rationale
The current freezing and thawing test method in C67/C67M typically requires a minimum of 12.5 weeks to complete. Method B is an automated method based on C666/C666M that has been adapted to testing brick and requires specialized hardware but provides the same pass/fail performance as Method A in typically 2.5 to 3 weeks of testing and has failure responses that better mimic those in typical application. Research testing was performed to adapt the methods used in ASTM C666/C666M to test fired units and provide pass/fail results that were statistically no different to the existing method in ASTM C67/C67M.
