ISO 7148-2:2012

Plain bearings — Testing of the tribological behaviour of bearing materials — Part 2: Testing of polymer-based bearing materials

This part of ISO 7148 specifies tribological tests of polymer-based plain bearing materials under specified working conditions, i.e. load, sliding velocity and temperature, with and without lubrication. From the test results, data are obtained which indicate the relative tribological behaviour of metal-polymer and polymer-polymer rubbing parts. The purpose of this part of ISO 7148 is to obtain, for polymer material combinations used in plain bearings, reproducible measured values for friction and wear under specified and exactly-defined test conditions without lubrication (dry surfaces) and with lubrication (boundary lubrication). 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 - 2. del: Preskušanje materialov za ležaje na osnovi polimerov

Ta del standarda ISO 7148 določa preskuse za materiale za ležaje na osnovi polimerov glede na tribološke lastnosti pod določenimi delovnimi pogoji, t. j. obremenitev, drsna hitrost in temperatura, z mazanjem ali brez. Preskusni rezultati zagotavljajo podatke, ki kažejo relativne tribološke lastnosti delov kovina-polimer in polimer-polimer, ki so izpostavljeni drgnjenju.
Namen tega dela standarda ISO 7148 je pridobiti ponovljive izmerjene vrednosti trenja in obrabe kombinacij polimernih materialov pod določenimi in natančno opredeljenimi preskusnimi pogoji brez mazanja (suhe površine) in z mazanjem (mejno mazanje). 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.
