Ngaba uyazi umahluko phakathi kovavanyo lohlobo kunye nesiqinisekiso semveliso? Esi sikhokelo sifanele sicacise umahluko, njengoko ukudideka kwimarike kunokubangela ukhetho olubi.
Iintambo zingaba nzima xa kusakhiwa, zineeleya ezininzi zezinto zesinyithi nezingezizo zesinyithi, zineentlobo ngeentlobo zobukhulu kunye neenkqubo zokuvelisa ezahluka ngokuxhomekeke kwimisebenzi yentambo kunye neemfuno zokusetyenziswa.
Izinto ezisetyenziswa kwiileya zekhebula, oko kukuthi, ubushushu, izinto zokulala, isheya, izizalisi, iiteyiphu, izikrini, iingubo, njl.njl., zineempawu ezikhethekileyo, kwaye ezi kufuneka ziphunyezwe rhoqo ngeenkqubo zokuvelisa ezilawulwa kakuhle.
Ukuqinisekiswa kokufaneleka kwentambo kwisicelo sayo esifunekayo kunye nokusebenza kwayo kwenziwa rhoqo ngumvelisi kunye nomsebenzisi wokugqibela kodwa kunokwenziwa nazimibutho ezizimeleyo ngokuvavanya nokuqinisekisa.
Uvavanyo lohlobo lomntu wesithathu okanye uvavanyo lwexesha elinye
Kufuneka kukhunjulwe ukuba xa kuthethwa "ngovavanyo lwentambo", lunokuba luvavanyo olupheleleyo ngokomgangatho othile woyilo lohlobo lwentambo (umz., BS 5467, BS 6724, njl.njl.), okanye lunokuba lolunye nje lovavanyo oluthile kuhlobo oluthile lwentambo (umz., uvavanyo lomxholo weHalogen olufana ne-IEC 60754-1 okanye uvavanyo lokukhupha umsi ngokwe-IEC 61034-2, njl.njl. Kwiintambo ze-LSZH). Amanqaku abalulekileyo ekufuneka aqatshelwe xa umntu wesithathu engavavanywanga ngala:
· Uvavanyo lohlobo lwentambo lwenziwa kuphela kubungakanani bentambo/isampulu enye kuhlobo oluthile lwentambo/ulwakhiwo okanye i-voltage grade
· Umenzi weentambo ulungisa isampuli kumzi-mveliso, ayivavanye ngaphakathi aze ayithumele kwilabhoratri yomntu wesithathu ukuze ivavanywe.
· Akukho kubandakanyeka komntu wesithathu ekukhethweni kweesampuli okukhokelela ekurhanelweni kokuba kuphela "iisampuli zeGolide" ezilungileyo okanye ezivavanywayo.
· Nje ukuba iimvavanyo ziphumelele, iingxelo zovavanyo zohlobo lomntu wesithathu ziyakhutshwa
· Ingxelo yovavanyo lohlobo igubungela kuphela iisampulu ezivavanyiweyo. Ayinakusetyenziselwa ukubanga ukuba iisampulu ezingavavanywanga ziyahambelana nomgangatho okanye ziyahlangabezana neemfuno zeenkcukacha.
· Olu hlobo lovavanyo aluphindaphindwa rhoqo kwixesha leminyaka emi-5 ukuya kweli-10 ngaphandle kokuba lucelwe ngabathengi okanye ngabasemagunyeni/zinkonzo
· Ke ngoko, uvavanyo lohlobo luyifoto eyenzeka ngexesha, ngaphandle kovavanyo oluqhubekayo lomgangatho wekhebula okanye utshintsho kwinkqubo yokuvelisa okanye izinto eziluhlaza ngovavanyo oluqhelekileyo kunye/okanye ukujongwa kwemveliso.
Isatifikethi somntu wesithathu seentambo
Isiqinisekiso siphambili kunezinye iintlobo zovavanyo kwaye siquka uhlolo lweefektri zokwenza iintambo, kwaye kwezinye iimeko, uvavanyo lwesampulu yentambo minyaka le.
Amanqaku abalulekileyo ekufuneka aqatshelwe xa kuqinisekiswa ngumntu wesithathu ngala:
· Isiqinisekiso sihlala silungiselelwe uluhlu lweemveliso zekhebula (sigubungela zonke iisayizi zekhebula/ii-cores)
· Ibandakanya uhlolo lwefektri, kwaye kwezinye iimeko, uvavanyo lwekhebula lonyaka
· Ukuqinisekiswa kwesatifikethi kuhlala kusebenza iminyaka emi-3 kodwa kuphinda kukhutshwe ngokubonelela ngokuhlolwa rhoqo, kwaye uvavanyo luqinisekisa ukuhambelana okuqhubekayo
· Inzuzo ngaphezu kovavanyo lohlobo kukuqhubeka nokujonga imveliso ngokuhlolwa nokuvavanywa kwezinye iimeko
