Izingwegwe ezidlulisela ukuhlolwa kufanele zimakwe endaweni ephansi yengcindezi yezingwegwe, kufaka phakathi isisindo sokuphakamisa, ilebula lefektri noma igama lefekthri, inombolo yokuhlola nokunye.
Isihlokwana kufanele sishayelwe kunoma yiliphi amacala alandelayo:
① Ukuqhekeka;
② Isigaba esiyingozi sigqoka kuze kufike ku-10% ngosayizi wokuqala;
③ Ukuvulwa kungu-15% ngaphezulu kobukhulu bokuqala;
④ Hook Body Torsion deformation engaphezu kwe-10 °;
⑤ Ingxenye eyingozi ye-hook noma intamo ye-hook ikhiqiza i-deformation yepulasitiki;
