A new ASTM International standard will support the use of stucco in the construction industry. The new standard (soon to be published as C1860) was developed by the ASTM International committee on gypsum and related building materials and systems (C11).

“The new standard provides a way to measure the tensile strength or bond strength of stucco in vertical applications,” says ASTM International member and task group chair Matthew J. Innocenzi, P.E. “The results of this test method, when coupled with sound engineering mechanics and analyses, can be used as a tool to help evaluate the performance of stucco when subject to lateral loads.”

Innocenzi, principal of Nick Innocenzi and Sons Consulting Engineers and Associates LLC, notes that the standard fills an important need for a consensus-based test method for testing stucco. Engineers, architects, test specifiers, and consultants will all find the standard useful.
