A wet test is a useful addition to the standard dry compression test.
During a dry compression test, the first puff of the test shows 50 PSI and the maximum reading after 4 strokes is 150 PSI. This indicates A. that the cylinders are good. B. weak piston rings. C. a bad spark plug. D. a hole in the piston. Dry Compression Dry compression indicates the resistance of the mold to stresses during pouring and cooling of a casting and the ease of shakeout. Procedure - Dry compressive strength is the maximum load a dry specimen can sustain before fracturing. A standard 2 x 2-in. specimen is made and dried in a ventilated oven at 230F (110C) for 2 hr.The service manual states that the standard compression is 248psi, with a minimum of 138psi and maximum variance of 14psi. Results. Test 1: Dry test with the engine lukewarm Bank 1 (cylinder 1, 3, 5): 96, 135, 147 Bank 2: (cylinder 2, 4, 8): 154, 167, 217 Test 2: Dry test with the engine cold Bank 1 (cylinder 1, 3, 5): 24, 82, 99Apparatus for Concrete Cube Test.
