The SPFA Equipment Committee has completed the update of SPFA-137 TechDoc entitled "SPF High Pressure Equipment Guidelines." This is a substantial revision of the document, last published in 2005. It includes descriptions of all chemical handling equipment from the A- and B-component storage to the spray gun. Many thanks to the task group volunteers for this project including John Courier, Jake Jacobson, Nick Pagano, Joe Hearon and Tim Newmeyer.
