The subcommittee is responsible for standards relating to radiation or infrared (IR) temperature measurement. E20.02's standards are published along with the rest of the E20's standards in the Annual Book of ASTM Standards, Volume 14.03.
ASTM A354 is an ASTM International standard that defines chemical and mechanical properties for alloy steel bolts, screws, studs, and other externally threaded fasteners. It is officially titled: Standard Specification for Quenched and Tempered Alloy Steel Bolts, Studs, and Other Externally Threaded Fasteners .
ASTM A490 and ASTM A490M are ASTM International standards for heavy hex structural bolts made from alloy steel.The imperial standard is officially titled Standard Specification for Structural Bolts, Alloy Steel, Heat Treated, 150 ksi Minimum Tensile Strength, while the metric standard (M) is titled Standard Specification for High-Strength Steel Bolts, Classes 10.9 and 10.9.3, for Structural ...
A screw thread, often shortened to thread, is a helical structure used to convert between rotational and linear movement or force. A screw thread is an inclined plane wrapped around a cylinder or cone in the form of a helix, with the former being called a straight thread and the latter called a tapered thread.
The American Petroleum Institute (API) oldest and most successful programs is in the development of API standards which started with its first standard in 1924. API maintains over 500 standards covering the oil and gas field. [2] The following is a partial list specific to welding:
The federal standard for LA abrasion testing was formally adopted by the ASTM in 1937. [10] Decades later, field studies found that the LA test results do not always correlate with reality, thus engineers outside of the United States developed different national standards like the French wet micro-Deval procedure or the British Standard 812.
