ISO 8760:1990/Cor 1:2009

Overview

ISO 8760:1990/Cor 1:2009 is a technical corrigendum to the international standard ISO 8760:1990, issued by the International Organization for Standardization (ISO). This document specifically addresses the method for determining the mass concentration of carbon monoxide (CO) in workplace air using detector tubes designed for short-term sampling with direct indication. The corrigendum updates key technical aspects of the method to improve accuracy and reliability in industrial hygiene and occupational health monitoring.

Key Topics

• Workplace Air Quality: The standard focuses on assessing CO levels in occupational environments, ensuring safe air quality for workers.
• Carbon Monoxide Measurement: Provides a precise method for detecting mass concentration of CO, a critical toxic gas.
• Detector Tubes Method: Utilizes direct reading tubes for short-term sampling, offering quick and practical analysis without complex instrumentation.
• Technical Corrections:
  • Equation Adjustment: Corrects the symbol from “ρ(CO)” to “ϕ(CO)” in the concentration calculation formula for accurate representation.
  • Measurement Accuracy: Specifies that the reading error must be less than 4 ppm to keep the maximum random error under 25%, enhancing the method’s reliability.
• Standardization Committee: Developed by ISO Technical Committee 146 (Air Quality), Subcommittee SC 2 (Workplace Atmospheres), emphasizing its focus on occupational health.

Applications

This standard is essential for:

• Industrial Hygiene Monitoring: Enables environmental and safety professionals to measure CO exposure levels in factories, workshops, and other workplaces.
• Occupational Health and Safety Compliance: Helps organizations comply with regulatory requirements by providing a reliable and standardized method for CO detection.
• Short-Term Sampling Needs: Ideal for quick assessments of air quality to identify immediate hazards related to carbon monoxide poisoning.
• Risk Management: Supports hazard identification and control in environments where combustion processes or machinery may emit CO.
• Air Quality Research: Facilitates scientific studies related to workplace atmosphere contamination by carbon monoxide.
