Tijaabada adag ee caalamiga ahi dhab ahaantii waa qalab tijaabo ah oo dhamaystiran oo ku salaysan heerarka ISO iyo ASTM, taas oo u ogolaanaysa isticmaalayaasha inay ku sameeyaan tijaabooyinka adag ee Rockwell, Vickers iyo Brinell isla qalab.Tijaabada adag ee caalamiga ah waxa lagu tijaabiyaa iyada oo lagu salaynayo mabaadi'da Rockwell, Brinell, iyo Vickers halkii la isticmaali lahaa xidhiidhka beddelka ee nidaamka qallafsanaanta si loo soo saaro qiimayaal badan oo adag.
Miisaanka adag ee HB Brinell wuxuu ku habboon yahay in lagu cabbiro adkaanta birta shubka ah, alloysyada aan birta ahayn, iyo birta la shiiday ee kala duwan.Kuma haboona in la cabbiro muunado ama qaybo-shaqo oo aad u adag, aad u yar, aad u dhuuban, oo aan u oggolaan in jeexid weyn oo dusha sare ah.
Qiyaasta engegnaanta HR Rockwell waxay ku habboon tahay: tijaabinta caaryada, cabbiraadda qallafsanaanta ee qaybaha damay, la damiyay iyo kuwa kulaylka kululeeyay.
HV Vickers miisaan adag ayaa ku habboon: cabbiraadda adkaanta shaybaarada iyo qaybo yaryar oo leh meelo yaryar iyo qiyamka adagaanta sare, adkaanta lakabyada la dhex galiyay ama dahaarka ka dib daaweynta dusha kala duwan, iyo adkaanta walxaha khafiifka ah.
Kuwa soo socdaa waa horudhac ku saabsan taxanaha cusub ee tijaabiyeyaasha qallafsanaanta caalamiga ah: iyo shaashadda taabashada Tijaabada adag ee caalamiga ah
Si ka duwan tijaabada adag ee caalamiga ah, jiilka cusub ee tijaabiyaha qallafsanaanta caalamiga ah wuxuu isticmaalaa tignoolajiyada dareenka xoogga leh iyo nidaamka jawaab celinta xoogga xiran ee xiran si uu u beddelo qaabka culeyska culeyska, taasoo ka dhigaysa cabbirka mid fudud iyo qiimaha la cabbiray mid deggan.
Xoogga Imtixaanka:
Rockwell: 60kgf (588.4N), 100kgf (980.7N), 150kgf (1471N)
Rockwell sare: 15kg (197.1N) , 30kg (294.2N) , 45kg (491.3N)
Brinell: 5,6.25,10,15.625,25,30,31.25, 62.5, 100,125,187.5kgf (49.03,61.3,.5 306.5,612.9,980.7,1226,1839N)
Vickers: 5,10,20,30,50,100,120kgf (49.03,98.07,196.1,294.2,490.3,980.7,1176.8
