7. Maitiro Ekugadzira uye Kuongorora
EN 10253-2 Zvishandiso zveType B zvinopihwa neWomic Steel zvinogadzirwa uchishandisa controlledmaitiro ekugadzira kupisa kana kutonhora, zvichiteverwa nekuongororwa kwehukuru hwezvinhu.
Kuongorora nekuyedza zvakakosha zvinosanganisira:
● Kuongorora makemikari (spectrometer)
● Kuedzwa kwemakanika (kudhonza, kukanganiswa)
● Kuongorora mativi
● Kuyera ukobvu hwemadziro
● Kuongorora zvinoonekwa uye pamusoro
● NDT (UT / MT) yesarudzo kana wakumbira
Zvigadzirwa zvese zvinopihwa neEN 10204 3.1 kana 3.2 zvitupa, kuve nechokwadi chekuti zvese zvirimo zvinoteverwa. 
8. Kugona Kugadzira, Kurongedza uye Kutumira
● Hapana MOQ: Chidimbu chimwe chete chinogamuchirwa
●Saizi dzakajairika: Kutumirwa nekukurumidza kubva kustock
●Saizi hombe / zvinhu zvakakosha: Yakagadzirwa-ku-odha
●Kurongedza: VCI dziviriro yekudzivirira ngura + kurongedza kwakakodzera gungwa
●Kugadziriswa kwezvinhu: Mhinduro dzekufambisa dzegungwa, njanji, uye nzira dzakasiyana-siyana dzakagadziriswa
9. Maitiro Akajairika
EN 10253-2 Zvishandiso zveType B zvinoshandiswa zvakanyanya mu:
1. Masisitimu ekudziyisa uye HVAC
2. Mapaipi ekushanda kwemaindasitiri
3. Nzvimbo dzekuchenesa mvura
4. Mapaipi emagetsi nemagetsi
5. Masisitimu ekubatsira ebhaira
10. Sei Uchifanira Kusarudza Simbi Yevakadzi
Kutevedzera zvakasimbaEN 10253-2 Rudzi B
● Kutsvaga zvinhu zvakagadziriswa kwakasimba
● Kugona kwakakwana kuongorora
● Kugadzirwa kunochinjika uye mhinduro inokurumidza
● Ruzivo rwepasi rose rwekupa mapurojekiti
Tinodada nebasa redu rekugadzirisa zvinhu, kugadzira zvinhu nekukurumidza, uye network yedu yekutumira zvinhu pasi rose, tichiona kuti zvaunoda zvinosangana nemazvo uye neunyanzvi.
