OSHA will begin requiring accredited crane operator certification on November 10, 2018, the final compliance date, but since the 2017 delay the NCCCO has maintained not waiting. [5] The Associated General Contractors of America (AGC) joined with members of the Coalition for Crane Operator Safety (CCOS) and urged Congress to finalize the rule.
Associated Training Services, commonly known as ATS is a heavy equipment training institution based in Sun Prairie, Wisconsin. [1] [2] It was founded in 1959 by Robert Klabacka as the National Institute of Concrete Construction.
In practice this is not always feasible, since even in tensile tests, certain properties can be influenced by specimen size and/or geometry. Here is a listing of some of the most common tests: [2] Hardness Testing. Vickers hardness test (HV), which has one of the widest scales; Brinell hardness test (HB)
In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
It is also used in testing a specimen, for a process where the crosshead moves to load the specimen to a specified value before a test starts. Data is not captured during the preload segment. When tensile specimens are initially placed into testing grips, they can be subjected to small compressive forces. These forces can cause specimens to ...

It is standard industrial practice that the compressive strength of a given concrete mix is classified by grade. Cubic or cylindrical samples of concrete are tested under a compression testing machine to measure this value. Test requirements vary by country based on their differing design codes. Use of a Compressometer is common. As per Indian ...
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.
