ASTM E1792-24 PDF

Overview

ASTM E1792-24 is the internationally recognized standard specification for wipe sampling materials used to collect settled surface dust for the determination of lead. Published by ASTM International, this standard provides detailed requirements for the manufacturing, performance characteristics, testing, and packaging of towelettes designed for lead sampling. The aim is to ensure that laboratory analysis of lead in dust samples collected from surfaces is both accurate and reproducible, supporting safety, regulatory compliance, and public health initiatives.

Key Topics

• Wipe Material Requirements: Specifies physical and chemical properties necessary for effective lead dust collection, including background lead level, lead recoverability, collection efficiency, ruggedness, moisture content, mass, dimensions, and thickness.
• Performance Testing: Details standardized methods to verify wipe performance, using laboratory procedures described in referenced ASTM practices and test methods.
• Sample Handling: Sets guidelines for selecting, handling, and storing wipes prior to testing to ensure unbiased and contamination-free results.
• Packaging and Marking: Mandates individual wrapping, labeling with supplier and lot details, and explicit marking of compliance with ASTM E1792 on packaging.
• Recordkeeping: Requires suppliers to maintain performance data supporting compliance with the specification.

Applications

ASTM E1792-24 is utilized by:

• Manufacturers and Suppliers: To evaluate and demonstrate the compliance of wipe sampling materials for use in lead dust collection, ensuring their products meet technical and regulatory expectations.
• Environmental Health Professionals: To select effective wipes for sampling surface dust in buildings, particularly in environments where lead-based paint or residue is a concern, such as schools, homes, or industrial settings.
• Testing Laboratories: To ensure consistent collection and analysis methodology, contributing to reliable environmental monitoring and risk assessment results.
• Regulatory and Compliance Auditors: To verify that sampling materials used in inspection programs fulfill recognized international standards, supporting health and safety regulations.

By ensuring that the wipes possess low background lead, high collection efficiency, and sufficient durability, E1792-24 helps reduce contamination risk and enhances the confidence in analytical results for lead in surface dust. The standard also assists users in selecting between large and small wipes based on target area size, enhancing the practicality of field workflows.
