Preview of the June 24-26, 2012 Meeting of ASTM C24 on Building Seals and Sealants

Posted on 6/22/2012 10:45:03 AM By Bob Braun

In this blog, I am reporting on the diverse meeting activities that will take place very soon now in San Diego at the three day semi-annual meeting of ASTM C24.

Recently ASC has begun to partner with ASTM C24 on sealant Sustainability.  The last meeting in January provided major focus on this issue, and each subcommittee is charged with developing further actions, which are expected to lead to a future ASTM Standard.  Recently formed ASTM E60 also includes Subcommittee E60.01 on Building and Construction. You can join ASTM Committees through links at and participate in standards development.

I have been involved with C24 since 1997 and hold the chair of the C24.61 Subcommittee on Aerosol Foam Sealants.  I also participate in C16 on Thermal Insulation, D08 on Roofing and Water Proofing, D14 on Adhesives, E05 on Fire Standards, E06 on Building Performance, and E60 on Sustainability.

ASTM Committee C24 on Building Seals and Sealants was formed in 1959. C24 meets twice a year, usually in January and June, with about 50 members attending three days of technical meetings. The Committee, with a membership of approximately 248, currently has jurisdiction over 97 standards, published in the Annual Book of ASTM Standards.  Ken Yarosh is the current C24 Committee Chairman as well as the 2012 Chairman for all of ASTM.

C24’s current scope includes building seals and sealants include aerosol foam sealants, caulking compounds, elastomeric sealants, glazing compounds, preformed sealing tapes, and preformed gaskets.

At the San Diego meeting nine subcommittees will meet to work on creating new standards, and revising existing standards.  I have listed these below.

C24.01  Terminology
C24.03  Citations
C24.10  Specifications, Guides, and Practices
C24.20  General Sealants
C24.30  Adhesion
C24.40  Weathering
C24.61  Aerosol Foam Sealants
C24.73  Compression Seal and Lock Strip Gaskets
C24.87  International Standards
In addition, there will be a Sunday meeting of C24.90 (the Executive Committee), a closing Main Committee meeting, and the following special programs:

C24 Awards Reception/Dinner to recognize outstanding achievement of C24 members

C24 ASTM Presentation on Standards Videos, Value-Added Content, and Online Product Initiatives.  This is a new activity that should encourage each subcommittee to develop video summaries of their various standards and especially their test methods.  Chairman, Ken Yarosh, has personally encouraged this program and has posted a well done example on YouTube for elastomeric glazing sealants. This link is posted below. 

C24 ASTM Training Session on Responsibilities for Subcommittee Chairman, Task Group Chairman and Technical Contact

C24 Research & Liaison Session:  Elastomeric Wall Coatings

This is the annual “Committee Week” meeting, at which approximately ten different Main Committees will meet.  For example, D08 will also meet in San Diego with a full agenda of subcommittee meetings where their standards are created and improved; there will also be full Committee events as well.  D14’s next meeting will be Tuesday October 9th 2012 - Tuesday October 9th 2012.  The full agenda for this meeting has not been posted yet, but usually will be posted one or more months in advance of the meeting.

View the ASTM program for conducting ILS (Inter Laboratory Studies) explaining the protocol and the need to establish precision and bias statements for test methods whenever possible.

You can also view a third video link detailing the history and scope for the 2008 formation of ASTM E60 on Sustainability.

In Blog #7, I will summarize the progress and results from this meeting and review specific actions for C24.61 on aerosol foam sealant.  I hope to see much progress on new test method videos.  Also, I will focus on examples of current industry application videos showing how these can both educate and encourage the use of sealant and adhesives when appropriately done.

Any Questions?
