D5952-08 – Standard Test Method Technical Guide

The ASTM D5952 – 08 (Reapproved 2015) standard provides a critical framework for addressing the presence of Legionella in water systems and investigating potential outbreaks of legionellosis. This guide is specifically intended for employers, building owners and operators, facility managers, health and safety professionals, and public health authorities. It covers two distinct scenarios: (1) an initial concern that a water system may harbor Legionella, and (2) the identification of one or more cases of Legionnaires’ disease or Pontiac fever. Per Section 1.1, explicit disinfection and remediation protocols are beyond the scope of this guide. This standard prioritizes SI units (Section 1.2) and directs users to Sections 7.3 and 8.5 for critical hazard statements related to sampling and analysis.
