16. ABSTRACT (A 200-word or less factual summary of most significant information. It document includes a significant bibliography or
literaturo survey, montion it here.)

This publication is a formal report of the second Conference on
Measurements and Standards for Recycled Oil, held at the National
Bureau of Standards on November 29 and 30, 1977. There were seven
sessions on specific subject areas, with a total of 32 presentations
The subject areas were as follows: (1) The Existing Situation,
(II) Environmental Considerations, (III) Nonlubricating End Uses,
(IV) Legislation and Studies, (V) Evaluation of Re-refined Engine
Oils, (VI) Additional Recycled Oil Activities, and (VII) A panel
discussion on the topic: "What Data Base is Required to Establish
the 'Substantial Equivalency' on Re-refined Motor Oils to Virgin
Motor Oils." Included in this report are invited talks given and a
summary of the discussion following session VII.

PERIODICALS JOURNAL OF RESEARCH–The Journal of Research of the National Bureau of Standards reports NBS research and development in those disciplines of the physical and engineering sciences in which the Bureau is active. These include physics, chemistry, engineering, mathematics, and computer sciences. Papers cover a broad range of subjects, with major emphasis on measurement methodology, and the basic technology underlying standardization. Also included from time to time are survey articles on topics closely related to the Bureau's technical and scientific programs. As a special service to subscribers each issue contains complete citations to all recent NBS publications in NBS and nonNBS media. Issued six times a year. Annual subscription: domestic $17.00; foreign $21.25. Single copy, $3.00 domestic; $3.75 foreign. Note: The Journal was formerly published in two sections: Section A “Physics and Chemistry” and Section B “Mathematical Sciences." DIMENSIONS/NBS This monthly magazine is published to inform scientists, ngineers, businessmen, industry, teachers, students, and consumers of the latest advances in science and technology, with primary emphasis on the work at NBS. The magazine tighlights and reviews such issues as energy research, fire Hotection, building technology, metric conversion, pollution ibatement, health and safety, and consumer product perormance. In addition, it reports the results of Bureau prorams in measurement standards and techniques, properties if matter and materials, engineering standards and services, nstrumentation, and automatic data processing. Annual subscription: Domestic, $11.00; Foreign $13.75

NONPERIODICALS donographs—Major contributions to the technical literture on various subjects related to the Bureau's scientific nd technical activities. landbooks—Recommended codes of engineering and indusdal practice (including safety codes) developed in cooperaon with interested industries, professional organizations, nd regulatory bodies. pecial Publications Include proceedings of conferences ponsored by NBS, NBS annual reports, and other special ublications appropriate to this grouping such as wall charts, ocket cards, and bibliographies. pplied Mathematics Series—Mathematical tables, manals

, and studies of special interest to physicists, engineers, bemists

, biologists, mathematicians, computer programmers, ad others engaged in scientific and technical work. lational Standard Reference Data Series—Provides quantitive data on the physical and chemical properties of materials, compiled from the world's literature and critically laluated. Developed under a world-wide program codinated by NBS. Program under authority of National landard Data Act (Public Law 90-396).

NOTE: At present the principal publication outlet for these data is the Journal of Physical and Chemical Reference Data (JPCRD) published quarterly for NBS by the American Chemical Society (ACS) and the American Institute of Physics (AIP). Subscriptions, reprints, and supplements available from ACS, 1155 Sixteenth St. N.W., Wash., D.C. 20056. Building Science Series—Disseminates technical information developed at the Bureau on building materials, components, systems, and whole structures. The series presents research results, test methods, and performance criteria related to the structural and environmental functions and the durability and safety characteristics of building elements and systems. Technical Notes—Studies or reports which are complete in themselves but restrictive in their treatment of a subject. Analogous to monographs but not so comprehensive in scope or definitive in treatment of the subject area. Often serve as a vehicle for final reports of work performed at NBS under the sponsorship of other government agencies. Voluntary Product Standards Developed under procedures published by the Department of Commerce in Part 10, Title 15, of the Code of Federal Regulations. The purpose of the standards is to establish nationally recognized requirements for products, and to provide all concerned interests with a basis for common understanding of the characteristics of the products. NBS administers this program as a supplement to the activities of the private sector standardizing organizations. Consumer Information Series Practical information, based on NBS research and experience, covering areas of interest to the consumer. Easily understandable language and illustrations provide useful background knowledge for shopping in today's technological marketplace. Order above NBS publications from: Superintendent of Documents, Government Printing Office, Washington, D.C. 20402. Order following NBS publications-NBSIR's and FIPS from the National Technical Information Services, Springfield, Va. 22161. Federal Information Processing Standards Publications (FIPS PUB/Publications in this series collectively constitute the Federal Information Processing Standards Register. Register serves as the official source of information in the Federal Government regarding standards issued by NBS pursuant to the Federal Property and Administrative Services Act of 1949 as amended, Public Law 89-306 (79 Stat. 1127), and as implemented by Executive Order 11717 (38 FR 12315, dated May 11, 1973) and Part 6 of Title 15 CFR (Code of Federal Regulations). NBS Interagency Reports (NBSIR)—A special series of interim or final reports on work performed by NBS for outside sponsors (both government and non-government). In general, initial distribution is handled by the sponsor; public distribution is by the National Technical Information Services (Springfield, Va. 22161) in paper copy or microfiche form.
