ASTM E2255/E2255M-22

SIGNIFICANCE AND USE 4.1 This practice supports lead poisoning prevention activities by providing standardized procedures for conducting visual assessments. 4.2 This practice is intended to be used with other ASTM standards, as appropriate, for conducting lead-hazard assessments. 4.3 This practice is intended for use by individuals trained to conduct visual assessments associated with lead-hazard activities and in reporting their results. This practice is also applicable for use by others interested in visual assessment of properties for lead hazards, such as building code officials, building operators, homeowners, and insurers. SCOPE 1.1 This practice describes procedures for conducting visual assessments in buildings to visually identify the type and location of potential lead hazards. These potential hazards are associated with deteriorated leaded paint, lead in dust, or lead in soil. 1.2 This practice addresses visual assessment procedures for lead-hazard activities such as: lead risk (hazard) assessment (Guide E2115), clearance examination (Practices E2271/E2271M and E3074/E3074M), assessment of paint condition, and re-evaluation inspection. It also can be applied to visual assessments following paint maintenance or renovation or repainting activities, or combinations thereof. 1.3 Because there is considerable overlap among the requirements for lead-hazard activities, this standard first describes a generic visual assessment procedure, and then defines a specific procedure for each assessment type in terms of additions to, or deletions from, the generic procedure. 1.4 This practice does not address testing needed to confirm the presence of lead hazards. 1.5 This practice contains notes, which are explanatory and are not part of the mandatory requirements of this standard. 1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
