Konfigurasi Kekasaran Permukaan Menurut ISO 1302 – 1978 yang dimaksud dengan kekasaran permukaan adalah penyimpangan rata-rata aritmetik dari garis rata-rata profil. Definisi ini digunakan untuk menentukan harga dari rata-rata kekasaran permukaan. Ada 3 parameter yang digunakan untuk menentukan kekasarna permukaan, yakni 1. Ra adalah penyimpangan rata-rata dari garis rata-rata profil 2. Rz adalah ketidak rataan ketinggian pada sepuluh titik 3.

Karaszkiewicz tested this influence statically and concluded it to be small He also analysed the influence of among others the pressure varlation and temperature. The overall accuracy was estimated to be about 3 [mm 3 ] in leaked volume.

The influence of leakage caused by the piston motion of bis oil supply pump was not tested. Karaszkiewicz also measured out-leakage with the same method. He wiped the leaked oil from the rod, before starting an instroke, to prevent inleakage.

Additional use of a solvent did not make a significant difference. How much oi1 remained on the rod was not tested. Karaszkiewicz did not determine the mass of the removed oil for comparison with the oil flow measurement. Olssen (1972) measured the out-leakage of unpressurized 0-ring seals by determining the amount of oil, needed to restore the oil level in an open, vertical housing. During the experiment, leaked oil was removed from the rod (in fact being a steel ring of 2.5 [m] diameter and 25 [mm] cross-sectionat diameter) by washing it in a bath of trichlorethylene and drying it fll'st with a forced air stream and then with radiation.
