Compact tension specimens are used for experiments where there is a shortage of material available due to their compact design. For rolled materials the notch should be aligned with the roll direction where the material is weakest. This will allow the user to ensure that all results achieved are conservative (worst-case scenario).
Rising Step Load Testing (or RSL testing) is a testing system that can apply loads in tension or bending to evaluate hydrogen-induced cracking (also called hydrogen embrittlement). It was specifically designed to conduct the accelerated ASTM F1624 [ 1 ] step-modified, slow strain rate tests on a variety of test coupons or structural components.
High strain dynamic testing is a method of testing deep foundations to obtain information about their capacity and integrity, and in some cases, to monitor their installation. It is codified by ASTM D4945-12 - Standard Test Method for High-Strain Dynamic Testing of Piles.
Tensile testing on a coir composite. Specimen size is not to standard (Instron). Tensile testing, also known as tension testing, [1] is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure.
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.

Static load testing is an in situ type of load testing used in geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building. It differs from the statnamic load test and dynamic load testing in that the pressure applied to the pile is slower.
ASTM D5265- Standard Test Method for Bridge Impact Testing ASTM D5276- Standard Test Method for Drop Test of Loaded Containers by Free Fall ASTM D5277- Standard Test Method for Performing Programmed Horizontal Impacts Using an Inclined Impact Tester ASTM D5487- Standard Test Method for Simulated Drop of Loaded Containers by Shock Machines
The race is brought into contact with a square steel test block under a constant load. The contact area is flooded with the lubricant or grease being tested. The Timken OK Load is the highest standard load at which the spinning bearing race produces no scouring mark on the test block, but only a uniform wear scar. [1]
