ASTM D5337-23 PDF

Overview

ASTM D5337-23: Standard Practice for Setting and Verifying the Flow Rate of Personal Sampling Pumps specifies procedures for calibrating, setting, and verifying the flow rate of personal air sampling pumps in workplace environments. These pumps are essential tools in occupational exposure assessment, ensuring accurate collection of airborne contaminants for workplace air quality evaluation. The standard outlines best practices to maintain the precision and reliability of sampling equipment through traceable calibration methods and documentation.

By adhering to ASTM D5337-23, organizations can ensure that their air sampling results are accurate and reliable, supporting compliance with occupational health regulations and improving the protection of worker health.

Key Topics

• Flow Rate Calibration: Detailed steps for calibrating and verifying the flow rate of personal sampling pumps before and after workplace air sampling.
• Working Standard Flow Meters: Instructions for using both traceable and non-traceable working standard flow meters, with a preference for traceable devices.
• Traceability and Accreditation: Recommendations for ensuring calibration traceability to national or international standards, and the use of accredited laboratories.
• Measurement Devices: Guidance on implementing a variety of flow meters, such as bubble burettes, electronic near-frictionless piston meters, rotameters, and mass flow meters, for accurate volume measurements.
• Primary and Secondary Calibration: Procedures for both primary (traceable) and secondary (field) calibration devices, including establishment of calibration graphs.
• Quality Control: Requirements for pre- and post-sampling flow rate checks to identify potential deviations and ensure sampling integrity.
• Safety and Compliance: Emphasis on user responsibility in establishing proper safety, health, and environmental practices while applying the standard.

Applications

ASTM D5337-23 is crucial for a range of occupational hygiene and industrial hygiene applications:

• Workplace Air Monitoring: Ensures correct air sampling flow rates for accurate assessment of exposure to hazardous substances like dusts, fumes, vapors, and gases.
• Regulatory Compliance: Supports organizations in meeting occupational exposure limit requirements, and in preparing for regulatory inspections.
• Sampling Equipment Maintenance: Provides a consistent procedure for routine calibration, verification, and maintenance of personal sampling pumps to improve data quality.
• Health and Safety Programs: Enables professionals to establish reliable exposure monitoring programs that protect worker health and safety.
• Industrial and Laboratory Settings: Standardizes calibration procedures across different environments, from field sites to analytical laboratories, ensuring comparability of results.
