ANSI/IICRC S500 Water Damage Restoration

Standard and Reference Guide for Professional Water Damage Restoration (2015)

IICRC announces the publication of a newly revised ANSI-approved ANSI/IICRC S500 Standard and Reference Guide for Professional Water Damage Restoration (4th edition, 2015). To purchase the ANSI/IICRC S500 – 2015 in print, PDF, e-pub, or for subscription access, visit the IICRC webstore.

ANSI/IICRC S500-2015 provides a specific set of practical standards for water damage restoration. It does not attempt to teach comprehensive water damage restoration procedures; rather, it provides the foundation for basic principles of proper restoration practices. ANSI/IICRC S500-2015 does not attempt to include exhaustive performance characteristics or standards for the manufacture or installation of structural components, materials and contents (personal property).

ANSI/IICRC S500-2015 Standard for Professional Water Damage Restoration is a procedural standard. It is based on reliable restoration principles, research and practical experience. In addition, there has been extensive consultation and information obtained from numerous sources. These sources include, but are not necessarily limited to the scientific community, international, national and regional trade associations serving the professional restoration industry, chemical formulators and equipment manufacturers, cleaning and restoration training schools, restoration service companies, the insurance industry, allied trades persons and others with specialized experience. It is subject to further revision as developments occur in technology, testing and processing procedures.

According to S500 Chairman Mickey Lee, the primary revisions made to the Standard and Reference Guide since the 2006 edition was published, include the following:

  • Redefined the Classes of Water Intrusion to offer a more objective means of estimating the evaporation load in a building, basing it on amount of affected materials to be dried rather than by vague descriptions.
  • Restructured the Inspections and Structural Restoration chapters to flow generally in the order a restorer would perform the activities on a typical water intrusion project, making them more usable and easier to follow.
  • Consolidated information and recommended guidance on various materials which previously was scattered in three chapters (i.e. Building Science, Inspections, Structural Restoration) and placed them into a more user-friendly Table of Materials and Assemblies.
  • Provided a rationale for airmover placement based on amount of wet, affected surfaces that is applicable to all classes of water intrusions.
  • Strengthened the third-party references in the building science, microbiology, psychrometrics and drying technology chapters to reflect third party research and enhance their credibility.

ANSI/IICRC S500-2015 Standard and Reference Guide is presented using a two-part format: the standard itself and a supplementary reference guide. The procedural standard is featured in this first section, supported by the reference guide in the second section. The intent is to use the principles outlined in the reference guide as a tool to better understand and apply the standard itself. However, the reference guide is not considered part of this standard.

The S500 Consensus Body Chair is Mickey Lee, and Vice Chair is Chris Taylor. Consensus Body members are Larry Carlson, Jim Holland, Ron Reese, and Howie Wolf.
