Significance and Use
3.1 The purpose of this terminology standard is to help users understand and apply the large number of specialized terms used in connection with the management of lead hazards by providing a single, comprehensive, and consistent terminology.
3.1.1 This terminology standard includes some terms that may be encountered, but whose use is discouraged. They are included for clarification and in order to provide the user with preferred existing alternate terms.
3.1.2 Architectural terms for individual building components are included to promote consistency of usage and to help ensure that sampling locations are recorded with sufficient accuracy to allow independent confirmation of lead measurements, if necessary.
3.2 A discussion is attached to certain definitions to help make the definition clear or to show how the term and its definition are related to other terms.
3.3 Terms and definitions in this terminology standard are based upon laws, regulations, and practices in the United States of America.
3.3.1 Some of the definitions in this terminology standard are adopted verbatim or are adapted from definitions that are formally stated or implied in laws and regulations.

3.3.2 Users in other countries should refer to applicable national, regional, and local laws, regulations, and practices.
