ASTM E2144

ASTM E2144 is a technical standard for personal sampling and analysis of endotoxin in metalworking fluid aerosols in workplace atmospheres. It provides a structured approach for collecting and evaluating airborne exposure in environments where metalworking fluids may become aerosolized. This matters because consistent sampling and analysis can support more reliable exposure assessment, workplace hygiene decisions, and documentation when evaluating potential endotoxin-related concerns.

What is ASTM E2144?

ASTM E2144 is the Standard Practice for Personal Sampling and Analysis of Endotoxin in Metalworking Fluid Aerosols in Workplace Atmospheres. As a practice standard, it is intended to guide how personal exposure samples are collected and analyzed rather than to define product performance. Its technical focus is on endotoxin associated with metalworking fluid aerosols, making it relevant to exposure monitoring and laboratory analysis workflows. ASTM E2144 helps users apply a consistent method when assessing airborne conditions in work areas where metalworking fluids are present.

Where is ASTM E2144 used?

ASTM E2144 is commonly used in workplaces where metalworking fluids are applied and aerosolized during machining, cutting, grinding, or similar operations. It is relevant to industrial hygiene programs, exposure monitoring activities, and analytical laboratories that support workplace atmosphere assessments. The standard may also be used by safety and health professionals, quality teams, and compliance staff who need a defined method for personal sampling and analysis. ASTM E2144 is most useful when evaluating worker exposure in settings with potential endotoxin-containing aerosols.

Why is ASTM E2144 important?

ASTM E2144 is important because it supports consistent measurement practices for a workplace exposure concern that can otherwise be difficult to evaluate. Using a recognized standard can improve comparability between samples, strengthen documentation, and support more dependable decision-making in hygiene and compliance programs. For organizations managing metalworking fluid aerosols, the standard can help reduce uncertainty in testing and provide a clearer basis for exposure assessment, product evaluation, and risk management.
