Standard Guide for Pavement Management Implementation
Abstract: 4.1 This guide provides potential and current pavement management users with an outline of the process and steps to follow when implementing and operating pavement management systems. 4.2 This guide may be used by the ... -
Standard Guide for Examining Electrical and Mechanical Equipment with Infrared Thermography
Abstract: 4.1 This guide can be used by an end user to specify infrared examinations of electrical and mechanical equipment and an infrared thermographer to perform them. 4.2 This guide lists the joint responsibilities of the end ... -
Standard Specification for UNS N08367 Welded Tube
Abstract: The specification covers UNS N08367 welded tube of limited diameter and thickness for general corrosion applications. The tube shall be manufactured from flat-rolled alloy by an automatic welding process with no additional ... -
Standard Guide for Unrestricted Disposition of Bulk Materials Containing Residual Amounts of Radioactivity
Abstract: 6.1 Materials encountered during D&D may contain residual radioactivity varying in amounts from that in irradiated fuel to barely detectable quantities in or on building materials. It is clear that highly radioactive ... -
Standard Specification for Steel Transmission Tower Bolts, Zinc-Coated and Bare
Abstract: This specification covers the chemical and mechanical requirements of hexagon and square-head zinc-coated steel bolts and atmospheric corrosion-resistant bolts for use in the construction of transmission towers, substations, ... -
Standard Guide for Prioritization of Data Needs for Pavement Management
Abstract: 3.1 A key objective of all pavement management systems (PMS) is to provide a factual basis for improving the quality of decision making regarding the budgeting, design, programming, construction, maintenance, and operation ... -
Standard Practice for Reporting Particle Size Characterization Data
Abstract: 3.1 When evaluating the particle size information, if the procedures of the data processing are not available, the user of the data must make assumptions concerning the reported data in the event of analytical inconsistencies. ... -
Standard Specification for Trailers Used for Measuring Vehicular Response to Road Roughness (Withdrawn 2024)
Abstract: This specification details the design, performance, and operating features of trailers used for measuring vehicular response to road roughness. The instrumentation for sensing the movements of the trailer is, however, not ... -
Standard Test Method for Measuring Pavement Roughness Using a Profilograph
Abstract: 4.1 This test method provides a means for measuring the roughness of new or rehabilitated pavements. Results may differ between profilographs of different designs and therefore will not necessarily agree with roughness ... -
Standard Practice for Scanning Electron Microscope Beam Size Characterization
Abstract: 4.1 The traditional resolution test of the SEM requires, as a first step, a photomicrograph of a fine particulate sample taken at a high magnification. The operator is required to measure a distance on the photomicrograph ... -
Standard Test Method for Measurement of Vehicular Response to Traveled Surface Roughness (Withdrawn 2024)
Abstract: 4.1 This test method provides a means of evaluating traveled surface roughness. The measured values represent vehicular response to traveled surface roughness obtained with the equipment and procedures stated herein and ... -
Standard Specification for Glass Serological Pipets (General Purpose and Kahn)
Abstract: This specification covers reusable glass serological pipets used for measuring volumes of liquid. The pipets may be classified into three styles according to operational set-up and should be made with approved glass ... -

Abstract: This specification provides standard dimensional requirements for glass separatory funnels for general laboratory use. Separatory funnels shall be in the following types: Type 1A; Type 1B; Type 1C; Type 2; Type 3; and Type ... -
Standard Test Method for Measuring Pavement Macrotexture Depth Using a Volumetric Technique
Abstract: 5.1 This test method is suitable for research and development purposes and for field tests to determine the average macrotexture depth of a pavement surface. The knowledge of pavement macrotexture depth serves as a tool ... -
Standard Test Method for Measurement of Corrosion Sites in Nickel Plus Chromium or Copper Plus Nickel Plus Chromium Electroplated Surfaces with Double-Beam Interference Microscope
Abstract: 4.1 Different electroplating systems can be corroded under the same conditions for the same length of time. Differences in the average values of the radius or half-width or of penetration into an underlying metal layer are ... -
Standard Guide for Reflected–Light Photomicrography
Abstract: 4.1 This guide is useful for the photomicrography and photomacrography of metals and other materials. 4.2 The subsequent processing of the photographic materials is also treated. -
Standard Specification for Disposable Glass Micro Blood Collection Pipets
Abstract: This specification covers two dimensionally different (short and long) disposable glass micropipets used primarily to collect whole human blood specimens for clinical analysis and testing. Short and long pipets are available ... -
