Significance and Use
3.1 Prior to beginning a project that involves the removal, cutting, grinding, or burning of paint, it is necessary to determine if the coating contains hazardous metals, such as lead. If it does, certain requirements for worker and environmental protection may need to be imposed. The presence and quantity of hazardous metals in a paint can be determined through laboratory analysis. Proper sampling protocol is needed to assure the laboratory results represent the actual amount of heavy metal in the coating. The number and location of samples to be removed must also be determined to characterize properly the extent of the presence of hazardous materials, if any, on a structure.
Scope
1.1 This practice covers a method to control the removal of samples of coating films from substrates for subsequent laboratory analysis for heavy metal content on a mass basis. This technique can be used in the field, the fabricating shop, or laboratory.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
