This standard covers strain-gage force transducers, primarily those used in measurement systems. Included among the specific versions of strain-gage force transducers, to which this Standard is applicable, are the following: Tension Transducers Compression Transducers Universal...
The thickness of a coating is often critical to its performance. This magnetic method is suitable for measuring nondestructively the thickness of some nickel coatings and for specification acceptance. This method requires that the magnetic properties of the coating and its substrate be the same as...
This test method establishes the apparatus required, calibration and precision of the devices to be used, and the standard procedures for determining the measured speed, or volumetric flow rate, of oil diffusion pumps. This method shall make use of test dome, gage attachment or...
This Standard covers uni-directional and bi-directional strain-gage linear acceleration transducers. Included among the specific types of strain-gage linear acceleration transducers for which this Standard is applicable, are the following: Bonded, unbonded, deposited metallic, or...
Strain gauges are the most widely used devices for the determination of materials, properties and for analyzing stresses in structures. However, performance parameters of strain gauges are affected by both the materials from which they are made and their geometric design. These test methods detail...
This specification covers operating characteristics of tensile testing machines for the determination of the force-elongation properties of textile materials. Types of tensile machine covered in this specification are constant-rate-of-ext
This Standard is intended to establish uniform practices for the measurement of master rings or ring gages using horizontal methods. The standard includes requirements for geometric qualities of master rings or ring gages, the important characteristics of the comparison equipment,...
1.1 The purpose of this standard is to provide uniform test methods for the determination of strain gage performance characteristics. Suggested testing equipment designs are included. 1.2 Test Methods E 251 describes methods and procedures for determining five strain gage parameters:...
1.1 This test method describes the measurement of radiative or convective heat flux, or both, using a transducer whose sensing element (1, 2) is a thin circular metal foil. While benchmark calibration standards exist for radiative environments, no uniform agreement among practitioners or...

1.1 This guide covers the documentation and general procedures necessary to plan and conduct a geophysical log program as commonly applied to geologic, engineering, ground-water, and environmental (hereafter referred to as geotechnical) investigations. It is not intended to describe the specific or...
Movement of water in the unsaturated zone is of considerable interest in studies of hazardous-waste sites (1, 2, 3, 4) ; recharge studies (5, 6); irrigation management (7, 8, 9); and civil-engineering projects (10, 11). Matric-potential data alone can be used to determine direction of flow (11)...
This test method covers wet sieving techniques for determination of fineness of hydraulic cement and raw materials by means of the No. 50, No. 100, and No. 200 sieves. The following apparatus shall be utilized: wet test sieves; spray nozzle; pressure gage; balance; weights; brush; dry test...
The forest products finishing industry has encountered difficulties in measuring the temperature of painted surfaces prior to, during, and after the curing process. The use of thermocouples is not entirely satisfactory because the thermocouple wires tend to conduct heat away too rapidly from the...
Normalization of penetration resistance data is a frequently used method to evaluate the liquefaction susceptibility of sands. A large case history database from many countries has been accumulated to estimate instability of saturated sands during earthquakes (1,2,3,4). This test is used...
