SPRI Nuclear Moisture Testing Protocol Approved as ANSI Standard
WALTHAM, Mass. – A nuclear moisture testing protocol developed by SPRI – with the extensive input of RCI Inc. – has been approved by the American National Standards Institute (ANSI) as a national standard. SPRI represents sheet membrane and component suppliers to the commercial roofing industry and worked closely with RCI Inc. on the new ANSI/SPRI/RCI NT-1 2012 standard.
SPRI’s task force based its standard on a 20-year-old protocol, “Detection and location of latent moisture of building roofing systems by nuclear radio isotropic thermalization,” which can be found in Appendix E of RCI Inc.’s Manual of Practice. The document contains information on proper handling of nuclear based moisture survey equipment in the field, as well as calculating and analyzing survey results.
