O le Universal hardness tester o le mea moni o se su'esu'ega fa'apitoa e fa'avae i luga ole ISO ma le ASTM fa'ata'ita'iga, e fa'ataga ai tagata fa'aoga e fa'atino su'ega ma'a'a Rockwell, Vickers ma Brinell i meafaifa'aili tutusa.O le suʻega faʻamaʻa lautele e faʻataʻitaʻiina e faʻavae i luga o Rockwell, Brinell, ma Vickers mataupu faavae nai lo le faʻaogaina o le faʻaliliuga sootaga o le faiga maʻaʻa e maua mai ai le tele o tulaga faigata.
E tolu fua maaa e talafeagai mo le fuaina o mea faigaluega
Ole fua ole malosi ole HB Brinell e fetaui lelei mo le fuaina o le maaa o le u'amea lafo, u'amea e le o ni u'amea, ma u'amea fa'afefete ma fa'afefe.E le talafeagai mo le fuaina o faʻataʻitaʻiga poʻo mea faigaluega e faigata tele, laʻititi tele, manifinifi tele, ma e le faʻatagaina ni faʻailoga tetele i luga.
Ole fua ole malosi ole HR Rockwell e talafeagai mo le: fuaina o le maaa ole su'ega, tineia, tineia ma le fa'afefeina o vaega e togafitia ile vevela.
Ole fua ole malosi ole HV Vickers e fetaui lelei mo le fuaina o le maaa o faʻataʻitaʻiga ma vaega faʻatasi ma vaega laiti ma tulaga maualuga maaa, o le maaa o faʻapipiʻi faʻapipiʻi poʻo paʻu pe a maeʻa togafitiga eseese, ma le maaa o mea manifinifi.
Va'aiga fou o su'ega ma'a'a lautele
E ese mai le fa'ata'ita'iga fa'aleaganu'u fa'ale-aganu'u: o le tupulaga fou fa'ata'ita'i ma'a'a lautele e fa'aogaina le fa'aogaina o tekonolosi fa'amalosi ma le fa'aogaina o le fa'aogaina o le tapuni e sui ai le fa'ata'ita'iga o le fa'atonuina o le mamafa, fa'afaigofie le fua ma fa'amautu le tau.
Fa'ailoga tikeri o le fa'aautomatika: fa'aulu otometi ituaiga si'i a'e, pa'i mata fa'aaliga numera fa'aaliga, ituaiga fua fa'akomepiuta
