The information provided above has been furnished as a general guide-line for the design of chemical resistant construction. We cannot guarantee the data reported nor can we assume any liability in connection with its use. Please contact The Belden Brick Company for specific recommendations. Belden Chemical Resistant Floor Brick are manufactured to conform to the specification requirements of both ASTM C279 and ASTM C410 (industrial floor brick). Whenever close dimensional tolerances or minimal distortion is required, ASTM C410, Tables II and III should be used for the dimensional standards of the specification. | ||||
