Standard Practice for Determining the Extent of Cracking in a Sealant using the Difference between the Compressive and Tensile Modulus

Importancia y uso:

5.1 The intent of this practice is to quantitatively determine the amount of cracking of a sealant relative to an unexposed or uncracked sample. Some samples of sealant have been observed to exhibit some degree of cracking some period after installation. The degree of cracking is assessed visually in a qualitative manner that takes into account the area of the cracks at the exposed surface of the sealant, but does not take into account the depth or profile of the cracks. The degree of cracking in the sealant has been used as an indication of performance change.
