The importance of slump test in concrete work is to ensure consistency in the concrete. The test measures the workability of the concrete.
Measures the resistance to earth from a grounding system
it measures the ionization of the air.
A tensile test machine is designed to give a straight line pull on a member so that it measures only direct tensile stress given as the force applied divided by the member area
A load test is considered a direct test because it evaluates how a system performs under a specific load or stress by simulating actual user traffic and usage conditions. This testing measures various performance metrics, such as response times, throughput, and resource utilization, directly reflecting the system's behavior under expected operational loads.
The prothrombin time (PT) test measures how long it takes for blood to clot. This test evaluates the coagulation factors involved in the extrinsic pathway.
Capillary Coagulation Test
APTT, or Activated Partial Thromboplastin Time, is a blood test that measures the time it takes for blood to clot. It assesses the intrinsic and common pathways of coagulation, helping to evaluate bleeding disorders, the effectiveness of anticoagulant therapy, and the function of various clotting factors. A prolonged APTT can indicate issues such as hemophilia, liver disease, or the presence of anticoagulants. This test is commonly used in clinical settings to monitor patients on heparin therapy or to investigate unexplained bleeding.
PT/PTT and INR
INR is "International normalized ratio": it is a test for blood coagulation.
Time of onset, and age
24 hours
The principle of the heat coagulation test for proteins is based on the denaturation and coagulation of proteins when exposed to heat. By heating a solution containing proteins, the proteins unfold and aggregate, forming a visible clot or precipitate. This test is commonly used to assess the presence of specific proteins by noting the formation of a clot or precipitate upon heating.
A coagulation cascade is the sequence of biochemical activities, involving clotting factors, that stop bleeding by forming a clot.

Blue test tubes are typically used for blood coagulation (BC) tests.
