About this file
This document is an Attachment E detailing Blend Tolerance specifications for CARB (California Air Resources Board) Primary Gas Standards, specifically for Group III Gases. The table provides comprehensive blend tolerance parameters for various gases including THC (Total Hydrocarbons), CO (Carbon Monoxide), NOx (Nitrogen Oxides), CO2 (Carbon Dioxide), CH4 (Methane), and O2 (Oxygen).
The document presents a detailed tolerance matrix that specifies target concentrations, range values, span gas concentrations, and acceptable tolerance limits for each gas. Different concentration levels have varying tolerance percentages, ranging from 1% to 10%, with lower and upper concentration limits precisely calculated. For instance, at a 5 ppm THC target concentration, the tolerance is 10%, allowing a range between 3.96 and 4.84 ppm. The specifications appear to be critical for ensuring precise gas mixture standards and quality control in emissions testing and environmental monitoring contexts, particularly within California's regulatory framework.
