Plain bearings — Testing of the tribological behaviour of bearing materials — Part 1: Testing of bearing metals
1 Scope This part of ISO 7148 specifies tribological tests of metallic bearing materials for plain bearings under conditions of boundary lubrication. The test procedures described in this part of ISO 7148 enable the friction and wear behaviour of bearing material/mating/lubricant combinations to be compared with that of other combinations, thus facilitating the selection of a bearing material for running repeatedly or for long periods under conditions of boundary lubrication, low speed and continuous sliding. Owing to differences in test conditions, measured friction and wear values can be expected to vary from one test facility to another. The test results give useful information for practical application only if all parameters of influence are identical. The more the test conditions deviate from the actual application, the greater the uncertainty of the applicability of the results.

Drsni ležaji - Preskušanje materialov za drsne ležaje glede na tribološke lastnosti - 1. del: Preskušanje kovin za ležaje
Ta del standarda ISO 7148 opisuje preskušanje materialov za drsne ležaje glede na tribološke lastnosti pri mejnem mazanju.
Preskusni postopki, opisani v tem delu standarda ISO 7148, omogočajo primerjavo trenja in obrabe kombinacij ležajnega materiala/stikov/maziva z drugimi kombinacijami ter s tem olajšajo izbiro ležajnega materiala za neprekinjeno delovanje ali dolgotrajno delovanje pri mejnem mazanju, nizki hitrosti in nenehnem drsenju. Zaradi razlik med preskusnimi pogoji se lahko izmerjene vrednosti za trenje in obrabo razlikujejo med preskusnimi objekti. Preskusni rezultati zagotavljajo uporabne informacije za praktično uporabo samo, če so vsi parametri vpliva enaki. Bolj kot preskusni pogoji odstopajo od dejanske uporabe, večja je negotovost uporabnosti rezultatov.
