Ki sa ki estanda yo tès pou kontwa patikil lwil oliv?

Estanda tès yo pou gwosè patikil lwil oliv sitou gen ladan ISO4406 ak NAS1638.
ISO4406 Creole
The ISO4406 standard divides oil contamination into 26 levels based on the size of particle concentration. The country has revised and improved the ISO4406 standard, and the revised ISO4406:1999 stipulates that the pollution level counted by an automatic particle counter is represented by three particle concentration levels of>4um,>6um, and>14um, se sa ki, lè l sèvi avèk twa nimewo ki reprezante nivo a polisyon nan ISO4406.
NAS1638 Creole
The NAS1638 standard categorizes particles in oil into 14 pollution levels, divided into five intervals based on particle size: 5-15, 15-25, 25-50, 50-100, and>100um. Chak entèval pli lwen sibdivize nan nivo polisyon diferan.
Metòd tès ak ekipman
Metòd prensipal yo pou detekte gwosè patikil lwil oliv yo se fotoresist patikil gwosè mezi ak metòd mikwoskòp. Metòd mezi gwosè fotoresist la se pi apwopriye pou NAS1638 ak ISO4406 estanda, pandan y ap metòd la mikwoskòp se mwens souvan itilize. Ekipman deteksyon tankou analyser gwosè patikil PRUDI itilize teknoloji mezi fotoresist gwosè patikil epi li ekipe ak plizyè estanda, ki ka reyalize vitès konstan piki ak kontwòl egzak nan volim piki. Li gen pwisan fonksyon pwosesis done epi yo ka dirèkteman teste ak enprime rezilta deteksyon.
