NATIONAL BUREAU OF STANDARDS The National Bureau of Standards' was established by an act of Congress on March 3, 1901. The Bureau's overall goal is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the Nation's physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to promote public safety. The Bureau's technical work is performed by the National Measurement Laboratory, the National Engineering Laboratory, and the Institute for Computer Sciences and Technology. THE NATIONAL MEASUREMENT LABORATORY provides the national system of physical and chemical and materials measurement; coordinates the system with measurement systems of other nations and furnishes essential services leading to accurate and uniform physical and chemical measurement throughout the Nation's scientific community, industry, and commerce; conducts materials research leading to improved methods of measurement, standards, and data on the properties of materials needed by industry, commerce, educational institutions, and Government; provides advisory and research services to other Government agencies; develops, produces, and distributes Standard Reference Materials; and provides calibration services. The Laboratory consists of the following centers: Absolute Physical Quantities? Radiation Research - Thermodynamics and THE NATIONAL ENGINEERING LABORATORY provides technology and technical services to the public and private sectors to address national needs and to solve national problems; conducts research in engineering and applied science in support of these efforts; builds and maintains competence in the necessary disciplines required to carry out this research and technical service; develops engineering data and measurement capabilities; provides engineering measurement traceability services; develops test methods and proposes engineering standards and code changes; develops and proposes new engineering practices; and develops and improves mechanisms to transfer results of its research to the ultimate user. The Laboratory consists of the following centers: Applied Mathematics - Electronics and Electrical Engineering2 — Mechanical THE INSTITUTE FOR COMPUTER SCIENCES AND TECHNOLOGY conducts research and provides scientific and technical services to aid Federal agencies in the selection, acquisition, application, and use of computer technology to improve effectiveness and economy in Government operations in accordance with Public Law 89-306 (40 U.S.C. 759), relevant Executive Orders, and other directives; carries out this mission by managing the Federal Information Processing Standards Program, developing Federal ADP standards guidelines, and managing Federal participation in ADP voluntary standardization activities; provides scientific and technological advisory services and assistance to Federal agencies; and provides the technical foundation for computer-related policies of the Federal Government. The Institute consists of the following centers: Programming Science and Technology - Computer Systems Engineering.

Foreword The Recycled Oil Program of the Office of Recycled Materials, National Measurement Laboratory, National Bureau of Standards (NBS) was formed in 1976 in direct response to the Energy Policy and Conservation Act of 1975 [P.L.94-163, Section 383; 42 U.S.C. 6363(c)]. The goal of this program, as described in this legislation, is to develop test procedures for the determination of substantial equivalency of re-refined or otherwise processed used oil with new oil for various end uses. This legislative responsibility is appropriate for NBS because it involves both the development and evaluation of measurement methods and standards, and because it requires the independent third-party role for acceptance by all concerned parties (virgin oil refining industry, oil re-refining industry, user industries, and government regulators). During the year since our first conference, there have been many new developments in the area of oil recycling. An important new development was passage of the Resource Conservation and Recovery Act (P.L. 94-580). The implications of this law for Federal government specifications and procurement of recycled oil are significant. Also, numerous state laws have been enacted on the subject of oil recycling. Inherent in these new developments, however, is the continued strong need for reliable test procedures and standards, to ensure adequate performance criteria and encourage consumer acceptance for recycled oil products. This volume contains the proceedings of the second Conference on Measurements and Standards for Recycled Oil held at NBS on November 29 and 30, 1977, almost exactly one year after the first conference. As stated above, there were many new developments in oil recycling during this past year, and these proceedings contain information on most of them. In addition to the presentations, these Conferences provide the very valuable service of bringing together the many persons interested in recycled oil from different sectors, public and private, to discuss the new developments, the problems, and hopefully, some of the solutions. These proceedings should be of value to the many people and organizations who are interested and involved in encouraging oil recycling. John D. Hoffman National Measurement Laboratory |
