1.1 This terminology standard covers definitions for the following: 1.1.1 Terms that are commonly used in the field of management of lead hazards in facilities; 1.1.2 Architectural terms, particularly those associated with older wood-frame buildings; and, 1.1.3 Specialized terms that may be encountered by users in reports and notices that are generated during lead hazard management activities. 1.2 This terminology standard is supplementary to Terminology E631 . 1.3 Definitions adopted or derived from other documents include the following: 1.3.1 Some of the definitions in this terminology standard are adopted as exact copies from other sources. The source is briefly identified at the right margin following the definition and fully identified in Section 2 . 1.3.2 Some of the definitions in this terminology standard are adapted from other sources.
