The use of rolling devices can provide a means to evaluate the adhesion of weather seals, for quality control in new installations, general evaluation of existing installations, and the investigation of water and air leakage through building enclosures. In order to better facilitate the use of rolling devices, ASTM International Committee C24 on Building Seals and Sealants is developing a…

In the past, the only measurement used to determine whether sealants could endure a great deal of foot traffic was hardness. Because research presented at symposia and from the field has shown that other factors need to be considered in the design and use of traffic sealants, ASTM International Committee C24 on Building Seals and Sealants has a new proposed standard that encompasses a wider range…
