ANSI/SPRI RD-1 is a reference for those who design, specify or install retrofit roof drains, which are designed for installation in existing drain plumbing on existing roofs. This standard does not include consideration of all roof storm water drainage code requirements for specific Hutto TX Roof building sites.
SPRI developed the ANSI/SPRI RD-1 standard for use by architects, engineers, consultants, roofing contractors and property owners of low-slope roofing systems in 2004, and it was last revised and re-approved as an ANSI standard in 2014. The standard is available for download at no cost at www.spri.org.
In addition, SPRI is reviewing ANSI/SPRI IA-1 "Standard Field Test Procedure for Determining the Mechanical Uplift Resistance of Insulation Adhesives over Various Substrates" and plans to canvass the document for re-affirmation as an American National Standard in the coming months.
This standard specifies a field-testing procedure to determine the mechanical uplift resistance of specific roof insulation/adhesive combinations. The testing procedure, which encompasses various types of adhesives, substrates and insulations, was first approved as a national standard in 2005 and again in 2010 and 2014.
