- Ulwahlulo kunye nokumelwa kophawu
3.1Cukuphelelwa amandla
3.1.1 ngokwenqanaba lomgangatho:
a) umgangatho woku-1 (PSL1);
b) umgangatho we-2 (PSL2).
Qaphela: I-PSL2 ibandakanya iimfuno zokongezwa kweekhemikhali, iimpawu zoomatshini, ukuqina, ubungakanani beenkozo, ukubandakanywa okungezona isinyithi, ukuqina, njl.
3.1.2 ngokusetyenziswa kwemveliso:
a) intsimbi yombhobho wokuhanjiswa kwerhasi yendalo;
b) intsimbi ye-oyile ekrwada kunye nemibhobho yeoli yemveliso;
c) intsimbi yolunye ulwelo lombhobho odityanisiweyo.
3.1.3 ngokwemeko yonikezelo:

b) ukulungelelanisa kunye nokuqhelanisa ukuqengqeleka (n);
c) ukuqengqeleka koomatshini abashushu (m);d) ukucima + ukuthambisa (q).
3.1.4 ngokweedge state:
a) ukusika edge (EC);
b) akukho ukucheba (EM).
3.2 ukumelwa kophawu
3.2.1 uphawu lwentsimbi luqulunqwe ngonobumba wokuqala wesiNgesi othi "umgca" omele umbhobho wokuhambisa, ubuncinci obuchaziweyo bexabiso lexabiso lombhobho wensimbi kunye nesimo sokuhanjiswa (izinga lekhwalithi yePSL2 kuphela).
Umzekelo: l415m.
L — ileta yokuqala yesiNgesi emele “umgca” wombhobho wothumelo;
I-415 - imele ubuncinci obuchaziweyo bexabiso lamandla ombhobho wensimbi, iyunithi: i-MPa;
M — imele ukuba ubume bonikezelo yi-TMCP.
3.2.2 ukongeza kumagama ku-3.2.1, ezinye iibrendi ezidla ngokusetyenziswa zikwanikwe kwiTheyibhile yoku-1.
Uphawu luquka "X" emele intsimbi yombhobho, ixabiso elincinane elichaziweyo lamandla emveliso yombhobho wentsimbi kunye nesimo sokuhanjiswa (izinga lekhwalithi yePSL2 kuphela).
Umzekelo: x60m.
X -imele intsimbi yombhobho;
I-60-imele ubuncinci obuchaziweyo bexabiso lamandla exabiso lombhobho wensimbi, iyunithi: Ksi (1ksi = 6.895mpa);
M -imele ukuba imeko yokuhanjiswa yi-TMCP.
Qaphela: awona mandla asezantsi esivuno achaziweyo akaqukwanga kumabakala A no-B.
3.2.3 jonga iThebhile 1 yesimo sokuhanjiswa kunye ne-brand ye-PSL1 kunye ne-PSL2 yensimbi.
3.2.4 bhekisa kwiSihlomelo A kwitheyibhile yothelekiso yolu phawu lusemgangathweni kunye nomgangatho ofanelekileyo.
