Annual report describing the activities and goals of the National Voluntary Laboratory Accreditation Program (NVLAP) during 1982, and a directory list of laboratories including the test methods for which they are accredited.

Abstract: This report presents a long-range plan for roofing research. The plan was developed in response to a need for roofing research addressing major materials problems and changes in low-sloped roofing materials technology. The intent of the plan is to establish the technical basis for developing standards and minimum levels of performance to assist in the selection of cost-effective and durable roofing materials. Four major areas of needed research are identified: (1) low-sloped roofing systems, (2) roofing membranes including single-ply and built-up, (3) thermal insulation for roofing systems, and (4) condition assessment and repair of roofs. Within each research area, a goal is given as well as a number of objectives to achieve the goal. A recommended approach to accomplish each objective is also given.

Abstract: This report summarizes NBS standards committee activities and accomplishments during, calendar year 1982. It describes the management of standards activities at NBS, profiles NBS staf* participation on outside standards committees, and highlights significant technical and individual contributions made by NBS staff. In 1982, 457 staff members (or 29% of NBS' professional, scientific, and technical staff) participated in 1,046 outside standards committees of 97 national and international standards organizations.

A report on research conducted by the National Engineering Laboratory, the National Measurement Laboratory, and the Institute for Computer Sciences and Technology under the direction of the National Bureau of Standards. It also presents the services and special programs offered by the Bureau to researchers and organizations.
