Tijaabada Biyo-baxa:
Dhuumaha Birta waa in si Hydraul ahaan ah mid mid loo tijaabiyaa. Cadaadiska Imtixaanka ugu badan waa 20 MPa. Cadaadiska Tijaabada, wakhtiga xasilinta waa in aanu ka yarayn 10 S, tuubada birta ahna waa in aanay daadan.
Ka dib markii Isticmaaluhu ogolaado, Tijaabada Haydarooliga waxa lagu bedeli karaa Tijaabada Eddy Iminka ama Tijaabada Faleeska magnetic.
Tijaabada fidsan:
Tuubooyinka leh dhexroorka bannaanka ee ka weyn 22 mm ayaa la marsiin doonaa imtixaan fidsan. Ma jiro kala-bax muuqda, baro cad, ama wasakh ah oo ah inay dhacaan inta lagu jiro tijaabada oo dhan.
Tijaabada Daboolida
Marka loo eego shuruudaha iibsadaha oo lagu sheegay qandaraaska, Dhuumaha birta ah ee leh dhexroorka dibadda ≤76mm iyo dhumucda gidaarka ≤8mm waxaa la samayn karaa tijaabin gubasho ah. Tijaabada Waxa Lagu Sameeyay Heer Kulka Qolka Iyada Oo Taper Ah 60 °. Daboolida ka dib, heerka ololka ee dhexroorka dibadda waa in uu buuxiyaa shuruudaha shaxda soo socota, iyo walxaha imtixaanku waa in aanay muujin dildilaacyo ama dildilaacyo
Imtixaan Adag:
Tijaabooyinka adag ee Brinell ama Rockwell waa in lagu sameeyaa muunado laga soo qaado laba tubbo oo qayb kasta laga soo qaaday
