Fine dust concentration, specifically PM4, in granular materials is a key parameter for evaluating potential emission factors. LCS Laboratory Inc. provides highly sensitive and reliable testing to support industrial hygiene consultants and professionals in maintaining safe environments.
Purpose of the Service
The PM4 concentration test determines the amount of fine dust present in materials such as soil, sand, recycled concrete, construction dust, and sawdust. This analysis is essential for estimating dust emission factors, assessing environmental impact, and ensuring compliance with safety standards.
Technical Details About the Test
- Methodology: Our test is based on ASTM D7928, “Particle-Size Distribution of Fine-Grained Soils Using the Sedimentation Analysis.”
- Enhanced Precision: The method has been modified to replace the standard hydrometer with gravimetric analysis, significantly improving sensitivity to 10 mg/kg.
- Sample Requirements: A 1 kg sample is required for testing and should be delivered in a metal or plastic container.
- Comprehensive Reporting: The 4-micron fraction is extracted, measured, and reported with precision. Further analysis for harmful components like quartz or metals can be conducted upon request.
