Tlhahlobo le liteko tsa bohlokoa li kenyelletsa:
● Tlhahlobo ea lik'hemik'hale (spectrometer)
● Teko ea mechine (ho tsitlella, ho ama)
● Tlhahlobo ea litekanyo
● Tekanyo ea botenya ba lebota
● Tlhahlobo ea pono le ea bokaholimo
● NDT (UT / MT) e ka ikgethang ha e kopuoa
Lihlahisoa tsohle li fanoa kaSetifikeiti sa EN 10204 3.1 kapa 3.2, ho netefatsa hore e fumaneha habonolo. 
8. Bokgoni ba Tlhahiso, Sephutheloana le Phano
● Ha ho MOQSengoathoana se le seng sea amoheleha
●Boholo bo tloaelehileng: Ho tlisoa kapele ho tsoa setokong
●Boholo bo boholo / thepa e khethehileng: E entsoe ho latela odara
●Sephutheloana: Tšireletso ea VCI khahlanong le mafome + paka e loketseng ho sea
●Thepa ea thepa: Litharollo tse ntlafalitsoeng tsa lipalangoang tsa leoatle, terene le tsa mekhoa e mengata
9. Litšebeliso tse Tloaelehileng
EN 10253-2 Mefuta ea B e sebelisoa haholo ho:
1. Mekhoa ea ho futhumatsa le ea HVAC
2. Liphaephe tsa ts'ebetso ea indasteri
3. Libaka tsa kalafo ea metsi
4. Liphaephe tsa eneji le tsa ts'ebeliso
5. Litsamaiso tse thusang tsa boiler
10. Hobaneng o lokela ho kgetha tshepe ya Womic
Ho latela melao ka tieoEN 10253-2 Mofuta oa B
● Ho fumana thepa e tala e tsitsitseng
● Bokhoni bo felletseng ba ho hlahloba
● Tlhahiso e tenyetsehang le karabelo e potlakileng
● Phihlelo ea lefats'e ka bophara ea phepelo ea projeke
Re motlotlo ka lits'ebeletso tsa rona tsa ho iketsetsa lintho, lipotoloho tse potlakileng tsa tlhahiso, le marang-rang a lefats'e a ho tlisa thepa, re netefatsa hore litlhoko tsa hau tse ikhethileng li fihlelleha ka nepo le bokhabane.
