1.1 These tables have been prepared by the National Institute of Standards and Technology to meet a demand from the wood preserving industry for convenient tables for reducing creosote volumes to the basis of 100176F (38176C) and for reducing specific gravity observations to the same temperature. Tables 1 and 2 give in parallel columns corrections factors for creosote and for mixtures of creosote and coal tar (up to 50% tar) designated as solution, and for coal tar. They are based on density determinations made on a selected range of domestic coke-oven tars.
1.2 Table 2 shows the volume occupied at 100176F (38176C) by a quantity of oil occupying a unit volume at the indicated temperature; for example, 1 gal of creosote measured at 120176F (49176C) will have a volume of 0.9921 gal at 100176F (38176C); thus, if the volume of creosote at 120176F (49176C) equals 10000 gal, then the volume at 100176F (38176C) equals 10000 times 0.9921 or 9921 gal.
1.3 Table 2 gives corrections for observed specific gravity which are simply made by adding them to the observed values for temperatures above 100176F (38176C) and subtracting them for temperatures below 100176F (38176C).
