ASTM A992 steel is a structural steel alloy often used in the US for steel wide-flange and I beams. Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m 3 (0.2836 lb/in 3). ASTM A992 steel has the following minimum mechanical properties, according to ASTM specification A992/A992M.
Wide-flange shapes are available in grade ASTM A992, [5] which has generally replaced the older ASTM grades A572 and A36. Ranges of yield strength: A36: 36,000 psi (250 MPa) A572: 42,000–60,000 psi (290–410 MPa), with 50,000 psi (340 MPa) the most common; A588: Similar to A572; A992: 50,000–65,000 psi (340–450 MPa)
The Izod impact strength test is an ASTM standard method of determining the impact resistance of materials. A pivoting arm is raised to a specific height (constant potential energy) and then released. The arm swings down hitting a notched sample, breaking the specimen. The energy absorbed by the sample is calculated from the height the arm ...
A first-order estimate of the relation between ASTM D2240 type D hardness (for a conical indenter with a 15° half-cone angle) and the elastic modulus of the material being tested is [10] = (+ +), where is the ASTM D2240 type D hardness, and is in MPa.
Ultimate strength of an element or member is determined in the same manner regardless of the load combination method considered (e.g. ASD or LRFD). Design load combination effects are determined in a manner appropriate to the intended form of the analysis results.
ASTM International, formerly known as American Society for Testing and Materials, is a standards organization that develops and publishes voluntary consensus technical international standards for a wide range of materials, products, systems and services. Some 12,575 apply globally.
S-Meter of a Ten-Tec Orion amateur radio transceiver. An S meter (signal strength meter) is an indicator often provided on communications receivers, such as amateur radio or shortwave broadcast receivers. The scale markings are derived from a system of reporting signal strength from S1 to S9 as part of the R-S-T system.
