| A325-04b - Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength |
| This specification covers two types of quenched and tempered steel structural bolts having a minimum tensile strength of 120 ksi for sizes 1.0 in. and less and 105 ksi for sizes over 1.0 to 1? in., inclusive.
The bolts are intended for use in structural connections. These connections are covered under the requirements of the Specification for Structural Joints Using ASTM A 325 or A 490 Bolts, approved by the Research Council on Structural Connections of the Engineering Foundation.
The bolts are furnished in sizes ? to 1? in., inclusive. They are designated by type, denoting chemical composition as follows:
Type Description
Type 1 Medium carbon, carbon boron, or medium carbon alloy steel.
Type 2 Withdrawn in November 1991.
Type 3 Weathering steel.

| A307-04 - Standard Specification for Carbon Steel Bolts and Studs, 60 000 PSI Tensile Strength |
|
This specification covers the chemical and mechanical requirements of three grades of carbon steel bolts and studs in sizes 1/4 in. (6.35 mm) through 4 in. (104 mm). The fasteners are designated by "Grade" denoting tensile strength and intended use, as follows:
Grade Description
Grade A Bolts and studs having a minimum tensile strength of 60 ksi (414 MPa) and intended for general applications,
Grade B Bolts and studs having a tensile strength of 60 to 100 ksi (414 to 690 MPa) and intended for flanged joints in piping systems with cast iron flanges, and
Grade C Nonheaded anchor bolts, either bent or straight, having properties conforming to Specification A 36/A 36M (tensile strength of 58 to 80 ksi (400 to 550 MPa)) and intended for structural anchorage purposes.

| E2368-04e1 - Standard Practice for Strain Controlled Thermomechanical Fatigue Testing |
| This practice covers the determination of thermomechanical fatigue (TMF) properties of materials under uniaxially loaded strain-controlled conditions. A "thermomechanical" fatigue cycle is here defined as a condition where uniform temperature and strain fields over the specimen gage section are simultaneously varied and independently controlled. This practice is intended to address TMF testing performed in support of such activities as materials research and development, mechanical design, process and quality control, product performance, and failure analysis. While this practice is specific to strain-controlled testing, many sections will provide useful information for force-controlled or stress-controlled TMF testing.

| E2246-02 - Standard Test Method for Strain Gradient Measurements of Thin, Reflecting Films Using an Optical Interferometer |
| This test method covers a procedure for measuring the strain gradient in thin, reflecting films. It applies only to films, such as found in microelectromechanical systems (MEMS) materials, which can be imaged using an interferometer. Measurements from cantilevers that are touching the underlying layer are not accepted.

| E2245-02 - Standard Test Method for Residual Strain Measurements of Thin, Reflecting Films Using an Optical Interferometer |
| This test method covers a procedure for measuring the compressive residual strain in thin films. It applies only to films, such as found in microelectromechanical systems (MEMS) materials, which can be imaged using an interferometer. Measurements from fixed-fixed beams that are touching the underlying layer are not accepted.

| E2244-02 - Standard Test Method for In-Plane Length Measurements of Thin, Reflecting Films Using an Optical Interferometer |
| This test method covers a procedure for measuring in-plane lengths (including deflections) of patterned thin films. It applies only to films, such as found in microelectromechanical systems (MEMS) materials, which can be imaged using an interferometer.

| E2208-02 - Standard Guide for Evaluating Non-Contacting Optical Strain Measurement Systems |
| The purpose of this document is to assist potential users in understanding the issues related to the accuracy of non-contacting strain measurement systems and to provide a common framework for quantitative comparison of optical systems. The output from a non-contacting optical strain and deformation measurement system is generally divided into optical data and image analysis data. Optical data contains information related to specimen strains and the image analysis process converts the encoded optical information into strain data. The enclosed document describes potential sources of error in the strain data and describes general methods for quantifying the error and estimating the accuracy of the measurements when applying non-contacting methods to the study of events for which the optical integration time is much smaller than the inverse of the maximum temporal frequency in the encoded data (that is, events that can be regarded as static during the integration time). A brief application of the approach, along with specific examples defining the various terms, is given in the Appendix.
