ASTM D804-97

1.1 Although the naval stores industry has been a continuing producer of chemical products for many centuries, the nature of the industry, its products, and its terminology have changed. In particular, the original practice of recovering naval stores through the processing of the exudate from pine trees (gum naval stores) has been supplemented by their extraction by solvent (wood naval stores) and by wood pulping chemicals (sulfate naval stores). Thus, this terminology contains some old terms now mostly of historic value, together with the terms of the modern naval stores industry.
