About This Item
ASTM E1979 is a technical standard that describes an ultrasonic extraction practice for preparing paint, dust, soil, and air samples for later lead determination. It is designed to support consistent sample preparation before analytical testing, which can improve comparability and reduce variability in results. By focusing on extraction rather than final analysis, the standard helps laboratories and field programs apply a more uniform approach when lead assessment is needed.
What is ASTM E1979?
ASTM E1979, titled Standard Practice for Ultrasonic Extraction of Paint, Dust, Soil, and Air Samples for Subsequent Determination of Lead, provides a defined practice for using ultrasonic energy to extract lead from collected samples. Its purpose is to support a consistent preparation step before lead measurement is performed by an appropriate analytical method. The standard is product-relevant for organizations that need a recognized ASTM standard to guide sample handling and extraction in a controlled, repeatable way.
Where is ASTM E1979 used?
This standard is commonly used in laboratories and environmental testing workflows where paint, dust, soil, or air samples are collected for lead evaluation. It is especially relevant when sample preparation must be standardized before instrumental analysis or compliance testing. ASTM E1979 may be applied in quality control settings, environmental assessment programs, and other technical workflows that rely on reliable extraction of lead from these sample types.
Why is ASTM E1979 important?
ASTM E1979 matters because consistent extraction is a key step in producing dependable lead test results. Using a recognized practice can help support compliance efforts, improve reproducibility, and reduce uncertainty in sample preparation. For purchasers and technical teams, the standard provides a clear reference for evaluating procedures, aligning laboratory methods, and supporting more defensible results in lead-related testing and reporting.
