Ububanzi obungaphandle
Ububanzi bangaphandle beepayipu abuyi kwahluka ngaphezu kwe-±1% ukusuka kububanzi bangaphandle obuchaziweyo.
Ubukhulu bodonga
Ubukhulu bodonga nangaliphi na ixesha akufuneki bube ngaphezulu kwe-12.5% phantsi kobukhulu bodonga obuchaziweyo.
Ubude
Iipayipu kufuneka zifakwe ngobude obungacwangciswanga, ubude obuphindwe kabini obungacwangciswanga, okanye ngobude obufanayo njengoko kuchaziwe kwiodolo yokuthenga, ngokuhambelana nale mida ilandelayo:
a. Ubude obungacwangciswanga obunye: 16 ukuya kwi-25ft (4.88 ukuya kwi-7.62mm), intshi
b. Ubude obuphindwe kabini obungacwangciswanga: Ngaphezulu kwe-25ft (7.62m) kunye nomyinge ophantsi we-35ft (10.67m)
c. Ubude obufanayo: ubude njengoko buchaziwe kunye notshintsho oluvumelekileyo lwe-±1 in.
Ubunzima
Ubude ngabunye benqwaba yepayipi bumele bulinganiswe ngokwahlukeneyo kwaye ubunzima bayo abufanele bube ngaphezulu kwe-15% ngaphezulu okanye i-5% phantsi kobunzima bayo obuqikelelwayo, bubalwa kusetyenziswa ubude bayo kunye nobunzima bayo ngobude beyunithi nganye.
