(Practice)Standard Practice for Field Sampling of Coating Films for Analysis for Heavy Metals
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) - Standard Practice for Field Sampling of Coating Films for Analysis for Heavy Metals provides a reliable methodology for collecting paint or coating samples from structures or components intended for laboratory analysis of hazardous heavy metal content. Developed by ASTM International, this standard is vital for projects where coatings may contain regulated substances like lead, requiring subsequent safety and environmental controls during removal, renovation, or demolition activities.
By ensuring that samples accurately represent the presence and concentration of heavy metals in coatings, ASTM D5702 helps stakeholders comply with regulatory requirements and maintain safe environments for workers and the public.
Key Topics
- Field Sampling Procedures: Defines controlled methods for removing coating samples from ferrous and non-ferrous substrates using tools such as knives or chisels, straight edges, and measuring gauges.
- Sample Selection: Outlines the need to select sample sites that accurately reflect coating variability, including painting history, prior repairs, and thickness measurements.
- Sample Handling: Provides instructions for transferring samples into clean containers such as plastic bags or polyethylene jars to prevent contamination.
- Documentation and Chain of Custody: Specifies requirements for labeling each sample container with identification, date/time, location, technician’s name, and accompanying chain of custody for traceability.
- Worker Safety and Environmental Considerations: Reminds users to implement appropriate safety, health, and environmental protocols and to observe applicable regulatory limits, as hazardous materials may be present in coatings or surface debris.
Applications
ASTM D5702 is broadly applicable wherever there is a need to identify and quantify hazardous metals in coatings prior to activities such as:
- Building Renovation and Demolition: Ensuring the identification of lead, chromium, or other hazardous metals in paint before starting removal or disturbance processes, to comply with health and safety regulations.
- Infrastructure Maintenance: Assessing bridges, water towers, or industrial structures during routine inspections or ahead of recoating projects to avoid unintentional exposure to hazardous constituents.
- Environmental Site Assessment: Characterizing potential contaminants on legacy industrial sites as part of due diligence, remediation projects, or regulatory compliance.
- Worker Safety Programs: Supporting development of protective measures for employees who may be exposed to hazardous metals during maintenance or decommissioning work involving coated surfaces.
- Laboratory Analysis Support: Providing representative field samples for certified laboratory testing to determine the actual mass of heavy metals present in coatings, crucial for accurate risk evaluation.
Related Standards
ASTM D5702 references or complements other widely used coating and sampling standards, including:
- ASTM D4138: Practices for Measurement of Dry Film Thickness of Protective Coating Systems by Destructive, Cross-Sectioning Means
- ASTM D6132: Test Method for Nondestructive Measurement of Dry Film Thickness of Applied Organic Coatings Using an Ultrasonic Coating Thickness Gage
- ASTM D7091: Practice for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to Ferrous Metals and Nonmagnetic, Nonconductive Coatings Applied to Non-Ferrous Metals
Adhering to internationally recognized methodologies such as ASTM D5702 helps ensure accurate field sampling of coatings, supports worker and public health, and aligns with best practices endorsed by the World Trade Organization’s technical barriers to trade principles.
