Physical and chemical properties are determined with the measurement of viscosity, acids formed during oil oxidation (neutralization number) and infrared spectrum analysis of tested oils. The results of testing the tribological characteristics of biodegradable repeceed-based hydraulic/transmission oils showed, that they exibit better or even similar mechanical properties, but worse oxidative stability compared with a corresponding mineral-based oil. The hydraulic/transmission rapeseed-based oils with their native properties and additives have similar lubrication properties as lubricants based on mineral oils, but they are in addition biodegradable and non-toxic</dc:description><dc:description xml:lang="sl">V prispevku smo predstavili fizikalno-kemijske lastnosti olj na osnovi oljne repice (oljne ogrščice) pred in med mehanskimi preskusi in po njih. Fizikalno-kemijske lastnosti smo spremljali z merjenjem viskoznosti kislih ostankov oksidacije (nevtralizacijsko število) in snemanjem infra rdečih spektrov preskušanih olj. Rezultati preskušanja triboloških lastnosti treh biološko razgradljivih repičnih hidravlično/reduktorskih olj so pokazali, da ima repično olje boljše ali vsaj enakovredne mehanske lastnosti vendar slabšo oksidacijsko stabilnost v primerjavi s kakovostno primerljivim mineralnim oljem. Repična hidravlično/reduktorska olja s svojimi naravnimi lastnostmi in z dodatki so po lastnostih podobna ustreznim mineralnim oljem, s tem da so biološko zelo razgradljiva in nestrupena</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-YAUPVWJA"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-YAUPVWJA" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-YAUPVWJA/4c92028d-d0db-4e0a-a5ed-13e753f31409/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-YAUPVWJA/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-YAUPVWJA" /></ore:Aggregation></rdf:RDF>
