ASTM Gypsum Committee developing 3 proposed lath standards.
Press Release Summary:
Developed by task group within Subcommittee C11.02, proposed lath standards will help assure that non-metallic lath products perform adequately, provide means for design professionals to generically specify products, and guide contractors in installation. ASTM WK24554, ASTM WK24555, and ASTM WK24556 standards address test methods, installation, and performance requirements of Non-metallic Plaster Bases (lathe) used with Portland Cement Based Plaster, respectively.

ASTM Gypsum Committee Developing Three Proposed New Lath Standards
W. CONSHOHOCKEN, Pa., August 4, 2009-The use of non-metallic plaster bases (lath) is growing in the construction industry, and minimum consensus standards are being set for installation, test methods and performance requirements. A task group within Subcommittee C11.02 on Specifications and Test Methods for Accessories and Related Products is currently developing three lath standards:
ASTM WK24554, Test Method for Non-Metallic Plaster Bases (Lath) Used with Portland Cement Based Plaster;
ASTM WK24555, Specification for Installation of Non-Metallic Plaster Bases (Lath) Used with Portland Cement Based Plaster; and
ASTM WK24556, Specification for Non-Metallic Plaster Bases (Lath) Used with Portland Cement Based Plaster.
Subcommittee C11.02 is part of ASTM International Committee C11 on Gypsum and Related Building Materials and Systems.
According to William Egan, manager, engineering and development, BASF Construction Chemicals LLC-Wall Systems, and a C11 member, each of the proposed new standards will help assure that non-metallic lath products perform adequately, provide a means for design professionals to generically specify products and guide contractors in installation.
"We expect that the proposed standards will be widely used and accepted after they've been approved," says Egan. "However, they're probably of most interest to design professionals, contractors, building owners and building officials."
All interested parties are invited to contribute to the ongoing development of these three work items. "It would be particularly helpful to have input and participation from additional manufacturers of non-metallic lath that currently do not participate in the ASTM standards development process," says Egan.
