Sep 30, 2020· Generally speaking, a compression test is a test performed on your engine to find out how much pressure is in your engine during operation. It is measured in pounds per square inch or PSI. If the test is passed each cylinder or piston will have a PSI within 10% of each other. Each car should have its own recommended compression setting.Sep 20, 2018· Typical gauge lengths for compression samples are 10-13mm, although they can go as low as 5mm. In comparison, the typical gauge length of a tensile specimen is around 160mm. This is due to the requirement to minimise a premature buckling failure. But what is the ideal gauge length to deliver the highest measured compressive strength for …
