Standard Practice for Field Sampling of Coating Films for Analysis for Heavy Metals
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.
1.3 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. For specific hazard information, see Section 5, Note 1, and Note 3.
1.4 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.

Overview
ASTM D5702-18(2022) is a globally recognized standard practice developed by ASTM International for the field sampling of coating films to analyze for heavy metals, such as lead. Proper identification and quantification of hazardous metals in coatings is crucial prior to conducting any project involving the removal, cutting, grinding, or burning of paint. The standard outlines a consistent method to control and document the removal of coating samples from various substrates, ensuring laboratory results reliably reflect the true content of heavy metals in the coating.
This method can be used in the field, fabrication shops, or laboratory environments. It is applicable to both ferrous and non-ferrous substrates, supporting environmental, health, and worker safety compliance in accordance with international standardization principles.
Key Topics
- Sampling Procedures: Provides step-by-step guidance on selecting appropriate areas for coating removal to accurately characterize the extent of hazardous metals present.
- Recommends removing a minimum of three samples per structure.
- Specifies cleaning sample areas and using precise tools for coating removal.
- Sample Collection and Handling:
- Stresses the use of clean, non-contaminating containers (e.g., polyethylene bags) for safe sample transport.
- Requires thorough documentation, including sample ID, date, location, and technician details.
- Accurate Measurement:
- Mandates measuring coating thickness with appropriate instrumentation (e.g., dry film thickness gauges).
- Emphasizes avoiding inclusion of substrate material to prevent contamination.
- Chain of Custody:
- Outlines documentation for maintaining sample integrity, from collection through laboratory analysis.
- Safety Considerations:
- Includes guidelines for developing site-specific health, safety, and environmental practices.
- Advises on special procedures if hazardous materials are likely to be present in surface debris and chalk.
Applications
ASTM D5702-18(2022) is essential in various industries and scenarios, including:
- Building Renovation and Demolition: Before initiating work that could disturb old coatings, use this standard to assess heavy metal content and determine necessary protective measures.
- Environmental Compliance: Organizations can demonstrate due diligence in identifying hazardous paints and coatings to meet regulatory requirements and minimize liability.
- Industrial Maintenance: Facilities operations rely on this standard to ensure safe processes during repainting, maintenance, or decommissioning activities.
- Historical Preservation: Restoration projects of heritage structures apply these practices to safeguard workers and comply with environmental protection standards.
- Quality Assurance: Ensures reliable sampling protocols for subsequent laboratory analysis, supporting accurate reporting and risk assessment.
