Emission factors for Compression Molding using SMC, BMC, LMC:

Pending Public Review

Uniform styrene emission factors for the compression molding of SMC (Sheet Molding Compound), BMC (Bulk Molding Compound), and LCM (Liquid Compression Molding) parts need to be available to the industry. A petition to modify the current ACMA UEF 1-2008 standard to add emission factors for the compression molding of SMC has accepted by the UEF Relevant committee. They have duly authorized the ballot by canvass panel of these petitions. For details please refer to the links below:

SMC Emission factor

Ballot Pending

Emission factors for the production of Sheet Molding Compound is needed for the compression molding segment of the composites industry. A petition to modify the name of the current ACMA UEF 2007 Estimating Emission Factors from Open Molding Composites Processes and to add emission factors for the production of SMC to has been accepted by the UEF Relevant committee. They have duly authorized the ballot by canvass panel of this petition. For details please refer to the links below:

LAGA emissions factor

Accepted into standard – 10/13/2009

ACMA has received the ANS Board of Standards approval of the petition for a new factor for lesser atomized gel coat application (LAGA) equipment . The standard will now have the designation of ANSI/ACMA/ICPA UEF-1-2009. The ACMA is an ANSI approved standards developer, and the UEF committee is the relevant standards committee that is responsible for the maintenance and modification of this standard. This revision will aid our members in satisfying state and federal requirements for permit compliance and reporting emissions.

Emissions from the Mechanical Non-atomized Application of Highly Filled DCPD Resins:

Accepted into standard – 4/2/2009

ACMA has received the ANS Board of Standards approval of the petition to include emission factors for highly filled DCPD resins in the ANSI/ICPA/ACMA UEF-1-2007. The standard will now have the designation of ANSI/ACMA/ICPA UEF-1-2009. The ACMA is an ANSI approved standards developer, and the UEF committee is the relevant standards committee that is responsible for the maintenance and modification of this standard. This revision will aid our members in satisfying state and federal requirements for permit compliance and reporting emissions.
