Xirmooyinka tuubbada xargaha-nooca birta ah oo bir ah ayaa guud ahaan ka kooban tuubbada tuubbada birta, xajiyeyaasha, saldhigyada, looxyada isgoysyada, iyo shabagyada amniga. Shuruuda loo adeegsado isticmaalka xargaha xargaha xargaha tuubbada tuubbada birta ah:
1. Kala dheereynta toosan ee toosan guud ahaan ma aha wax ka badan 2.0m, masaafada toosan ee toosan ma aha wax ka badan 1.5m, lakabka derbiga ah oo aan ka yarayn godyada isbadalka, iyo lakabka shaqada ayaa lagu daboolay guddiga isbadalka. Lakabka shaqada ayaa la tiriyey, oo lakabka lakabka oo ah mid wax lagu dhejiyo oo dhan 12m. Cabbirrada gaarka ah waa inay u hoggaansamaan jadwalka 6.1-1-1 iyo shaxda 6 ee "Nambarka Farsamada ee badbaadada xargaha qaab-dhismeedka xargaha xargaha-nambarka birta ah" (JGJL30).
2. Xeerarka 1-2 ama naqshad gaar ah.
Marka laga reebo tallaabada kore ee lakabka sare, kala-goysyada lakabyada kale waa inay ku xirnaadaan xargaha badhanka. Kala-goysyada laba xargaha toosan ee ku xiga looma dhigin isla masaafadaas, masaafada u dhaxaysa labada kala goys ee kala-goysyada ah ee ay u kala baxaan usha toosan ee jihada salka ah ma aha inay ka weynaato masaafada ugu weyn 1/3 ee. Haddii heerka sare ee heerka sare ee uu korsado dhererka isku-darka dhabta ah, dhererka dhabta dhabta ah waa inuusan ka yarayn 1000mm waana in lagu hagaajiyaa wax aan ka yarayn wax ka yar 2 xajiyeyaal ah, iyo masaafada u dhaxaysa geeska qaddarka xajiska daboolka daboolka ah kamana yaraan doono 10mm.
3. Usha toosan waa in lagu rakibaa sanka ugu weyn, oo lagu dhejiyey xargaha xaqa-xaqa-midig oo si adag ayaa loo mamnuucay in meesha laga saaro. Masaafada badhtamaha ee udhaxeysa labada xagal-xaqa xagasha ee xarkaha ugu weyn waa inaysan ka badnaan 150mm. Isboortiga laba-sawd-safka, kordhinta usha toosan hal dhamaadka darbiga waa inaysan ka badnaan 500mm.
4. Quusicirka waa inuu ku qalabeysan yahay ulaha ku dhegan oo toosan iyo toosan. Ololaha toosan iyo kuwa toosan waa in lagu hagaajiyaa ulaha aan ka badnayn 200mm ka fogeyn ka soo baxa Epithelium ee saldhigga salka ku haya xargaha xaqa-xaqa-midig. Marka aasaaska cirifka uusan ahayn isla heerka, cirka toosan ee toosan ee booska sare waa in lagu fidiyaa meesha hoose ee laba shaashad oo lagu hagaajiyey cirifka. Farqiga sare waa inuusan ka badnaan 1m. Masaafada ka socota dhidibka cirifka ka sarreeya jaranjarada si jaarka looga yaraado wax ka yar 500mm.
5. Laba-geesood isku-xidh-jilicsan Loogu talagalay hal-ku-dhafan oo isku xigta oo leh dherer ka yar 24m, xargaha darbiga ee adag waa in loo istcimaalaa si lagu kalsoonaan karo dhismaha, iyo hababka iskuxirka derbiga ee ku lifaaqan xargaha xirmooyinka iyo geedaha dusha sare ee lagu isticmaalo. Waa mamnuuc in la isticmaalo in la isticmaalo qaybaha darbiga ee dabacsan oo leh nabarro kaliya.
. Wixii lagu soo daray ee ku soo lifaaqan dherer ka badan 24m, marka lagu daro geesaha waa in lagu siiyaa jahwareerka toosan ee toosan, mid waa in lagu rakibaa 6 qof oo ku dhex jira dhexda. Burburkii dambe ee berrinka waa in loo habeeyaa qaab zigzag si isdaba joog ah uga socota hoose ilaa safka isku midka ah.
