Review of ASTM D4323 - 84(2009) Standard Test Method for Hydrogen Sulfide in the Atmosphere by Rate of Change of Reflectance in advance of a renewal ballot indicated this standard is in need of significant revision to represent current technology. Included in this revision is replacement of Fig. 1 and Fig. 2 with a single FIG. 1 Typical Rate of Change of Reflectance Type H2S System. Following, is the proposed revision of D4323.
Keywordsatmospheres; hydrogen sulfide; tape sampler; Air pollution/toxicity assessment; Atmospheric analysis; Field testing--atmospheric analysis; Health hazards; Hydrogen sulfide--atmospheric analysis; Pollutants; Rate of change of reflection; Reflectance and reflectivity--atmospheric analysis;
