Xa ndithumela iqela leizihlanganisi zentonga ezinemisontoUkusuka kumzi-mveliso wethu eXinchang, umbuzo endiwuva kakhulu kwiinjineli zokuthenga ngulo: “Ndingazi njani ukuba umsonto uza kungena xa ufika kwindawo?” Yingxaki efanelekileyo leyo. Intonga yomhlaba engenakudityaniswa ebaleni ayisiyongxaki nje kuphela - kukusilela kwenkqubo yomhlaba elindele ukwenzeka. Kweli nqaku, ndihamba ngemigangatho yomsonto, ukujonga ukunyamezelana, kunye namanyathelo okuvuma esampuli esiwasebenzisayo ngaphakathi kwaye ndicebisa ukuba umthengi ngamnye aqinisekise ngaphambi kokuba asayine iodolo yokuqala.

Kutheni Umgangatho Wentambo Kwintonga Yomhlaba Ayisiyo Inkcukacha Encinci

Ngokwamava am, i-electrode yokumisa iyasebenza kuphela njengelungu layo elibuthathaka. Kwindawo yethu yokuvelisa, sibone iisampulu ezibuyisiweyo apho ubhedu lwalungenasiphako emzimbeni wentonga kodwa umsonto wokudibanisa wawususiwe ngexesha lokuhamba kuba ukunyamezelana kwakungakhululekanga kwasekuqaleni. Iqela lethu le-QA lidlulise intonga kwitshekhi ebonakalayo kwizibuko lokulayisha, kodwa yasilela ebaleni ngexesha lokufakelwa konxweme eNtshona Afrika apho umakhi wayeqhuba iintonga kumhlaba we-laterite phantsi kwexesha elinzima.

Ngenxa yokuba intambo yibhulorho yoomatshini kunye neyombane phakathi kwamacandelo amabini entonga, intambo enqunyulwe kakubi okanye engagqunywanga kakuhle iba yeyona ndawo ixhathisa kakhulu kuyo yonke indlela yokumisa umhlaba. Loo ngxaki ibalulekile ngexesha lombane xa amashumi amawaka ee-ampere kufuneka anyamalale emhlabeni kwimizuzwana emincinci.

Xa sisenzaiintonga zentsimbi ezigqunywe ngobhedu olufakwe imisonto, umsonto uyasikwa okanye uqengqelwe emva kwenyathelo lokugquma ubhedu. Inkqubo yethu iqinisekisa ukuba olu landelelwano lukhusela umphezulu ogqunyiweyo ngexesha lokuyilwa, kodwa ikwathetha ukuba nayiphi na impazamo yobukhulu kumsonto ibonakala ngokuthe ngqo kwimveliso egqityiweyo. Akukho maleko we-buffer ofihlakeleyo wokufihla ingxaki.

Imigangatho yeMisonto oza kudibana nayo ekuThengeni iGrounding

Kwiminyaka elishumi elinesibini ndithumela iimveliso zomhlaba ngaphandle ezivela kumzi-mveliso wethu, ndisebenze nabathengi kumazwe angaphezu kwamashumi amane. Iifom zemisonto ezibonakala rhoqo kumaxwebhu e-RFQ eentonga zomhlaba kunye nee-couplings ziwela kwiintsapho ezine:

I-Unified National Coarse (UNC) — I-Default yaseMntla Melika

Iintambo ze-UNC, ezilawulwa yi-ASME B1.1, zilawula iimarike zase-US, eKhanada, naseMexico. Kwiintambo zomphezulu, ubukhulu obuqhelekileyo yi-5/8″-11 UNC kunye ne-3/4″-10 UNC. I-“11″ kunye ne-“10″ zibhekisa kwiintambo nge-intshi (TPI). Intambo ye-UNC ye-5/8″-11 inobubanzi obukhulu obuyi-15.875 mm kunye ne-pitch ye-2.309 mm. Sivelisa obu bukhulu ngobuninzi kubathengi abafaka iigridi zomphezulu wesitishi kunye neziseko zetower zonxibelelwano kulo lonke elasezantsi le-United States.

Sakha sabonelela ngefama yelanga embindini weTexas ngee-couplers ze-UNC eziyi-5/8″-11 zeentonga zomhlaba ezigqunywe ngobhedu ezitsalwe nzulu kwiimitha ezi-3 kumhlaba wodongwe. Umfakeli uxele ukuba kukho ukudibana okuthambileyo kulo lonke iqela kuba sasiqinisekisile ububanzi bepitch kwi-14.705 mm (ngaphakathi kwebhendi yokunyamezelana ye-2A) kwintonga nganye yeshumi ngexesha lokuveliswa.

Intlawulo yeSizwe eManyeneyo (i-UNF) — Ayiqhelekanga kangako kodwa isacacisiwe

Ngokwamava ethu, imisonto ye-UNF ivela kwiinkcukacha ezithile eziphenjelelwe yiYurophu nakwizicelo apho i-pitch ecolekileyo ikhethwayo ukuze kuxhathiswe ukungcangcazela. I-coupling ye-5/8″-18 UNF inobubanzi obufanayo nobomlingani wayo we-UNC kodwa iphantse iphindwe kabini kune-TPI. I-pitch ecolekileyo ithetha ukubandakanyeka okungakumbi nge-millimeter nganye yobude be-axial, iluncedo kumhlaba onamatye apho amandla okuqhuba aphezulu. Nangona kunjalo, imisonto ye-UNF ivakalelwa ngakumbi kukungqubana ngexesha lokuhlanganiswa kwentsimi, ngoko ke ndicebisa abathengi abachaza i-UNF ukuba bacele ne-chamfered lead-in kwisiphelo sesilisa se-coupling.

Umbhobho oqhelekileyo waseBritane (BSP) — Usasazeke kakhulu kuMbindi Mpuma naseAfrika

Imisonto ye-BSP, ingakumbi uthotho lwe-G (parallel) oluchazwe kwi-ISO 228, luqhelekile kwiinkcukacha ezivela kumazwe aseGulf, eNigeria, eKenya, naseMzantsi Afrika. Ukudibanisa kwe-G1/2 okanye kwe-G3/4 akunciphisi - kuxhomekeke ekulinganeni okulinganayo. Oku kwenza ukuqinisekiswa kobukhulu kube yinto ebaluleke ngakumbi kuba akukho senzo sokudibanisa ukuhlawula ubungakanani obuncinci. Ngamava ethu okubonelelaintonga yomhlaba kunye nentonga yomhlabaiimveliso kwiiprojekthi zaseDubai naseLagos, ii-BSP couplers ezidlula uvavanyo lwe-ring gauge kwisikhululo sethu se-QC zisebenza ngokuthembekileyo kumhlaba onesihlabathi, okwaziyo ukumelana nobushushu obuphezulu.

Imisonto yeMetric ISO (uthotho lwe-M) — Umgangatho weHlabathi

Imisonto yeMetric kwi-ISO 261 nakwi-ISO 965 zezona ziqhelekileyo kwilizwekazi laseYurophu, uninzi lwe-Asia, i-Ostreliya, kunye neendawo zaseMzantsi Melika. Kwiintonga zokumisa umhlaba, i-M16 kunye ne-M20 zezona zibukhulu ziqhelekileyo. I-M16x2.0 coupling inobubanzi obukhulu be-16 mm kunye ne-2.0 mm pitch. Udidi oluqhelekileyo lokunyamezelana yi-6g (yangaphandle) / 6H (yangaphakathi). Ngenxa yokuba imisonto yemetric ichazwe kwimigangatho ye-ISO eyamkelwe ziimibutho ezininzi zelizwe, isampuli edlula kwi-ring gauge ye-6g ngokubanzi iya kwanelisa abahloli nokuba iprojekthi ikweliphi ilizwe. Sigcina ii-couplers ze-metric-threaded zethu.iintonga zomhlaba zentsimbi ezigayiweyokwaye yethuiintonga zomhlaba zobhedu olucocekileyongobukhulu obuphakathi kwe-M12 ne-M24.

Ukunyamezelana Kwemisonto Nokufaneleka: Oko Kuthethwa Ngamanani Kwimisebenzi

Ukunyamezelana kwemisonto kusixelela ukuba iindawo ezimbini ziza kuhlanganiswa ngesandla, ngesitshixo, okanye aziza kuhlanganiswa kwaphela. Nantsi itheyibhile yesalathiso semigangatho yemisonto yentonga yomhlaba oza kudibana nayo:

Kwifektri yethu, sisebenzisa ii-ring gauges kunye nee-plug gauges ezilinganiswe kwezi bands zokunyamezelana kuyo yonke imveliso. Kumthengi ophonononga isampulu, icebiso elisebenzisekayo endinokulinika ngokusekelwe kwiminyaka yam kweli candelo: Ndisoloko ndiphethe i-mating coupler okanye i-gauge eyaziwayo xa ndisiya kuhlola isampulu. Ukuhlolwa kwe-go/no-go kuthatha ngaphantsi kwemizuzwana elishumi ngentonga nganye kwaye kubamba ukushukuma okunokulinganiswa kwe-caliper kuphela.

Iziphene Eziqhelekileyo Zemisonto Nendlela Yokuzibona

Kwiminyaka edlulileyo kumzi-mveliso wethu, ndidwelise iziphene ezibangela izikhalazo zasentsimini rhoqo. Nantsi into ejongwa liqela lethu le-QC kunye nabahloli babathengi bethu — kwaye ndicebisa ukuba uyijonge ngexesha lophononongo lwakho olulandelayo lwesampulu:

• Umonakalo odibanisa imisonto: Kwenzeka xa imisonto yendoda neyasetyhini ingalungelelananga ngaphambi kokuba iqiniswe. Imisonto yokuqala emibini ukuya kwemithathu ibonisa ukuguquguquka. Kwisampuli, oku kuzibonakalisa njengemvakalelo erhabaxa xa sijika ngesandla i-coupling. Siyisusa le nto kwimveliso ngokutshixa i-entry yentambo yendoda kuma-30 degrees.
• Ubukhulu obukhulu bedayamitha: I-thread crest edlula umda ophezulu we-tolerance band ayizukungena kwi-coupler. Oku kwenzeka rhoqo kwiintonga apho ukuqengqeleka kwentambo kwenziwa emva kokuba kufakwe i-copper coating kwaye i-coating yongeze ubukhulu obungalindelekanga. Silawula oku ngokujonga ubunzima be-coating kwindawo nganye ngaphambi kwenyathelo lokufaka i-thread.
• Ububanzi bepitch obungaphantsi kobukhulu: Ukulingana okukhululekileyo okuvumela ukuba i-coupling ijijeke. Nangona kunokubonakala kulula ngexesha lokuhlanganiswa, intambo ekhululekileyo ithetha indawo encinci yoqhagamshelwano kunye nokumelana okuphezulu kombane kwi-joint. Iinjineli zethu zibeka ii-rolling dies ukuze zijolise embindini we-tolerance band, kungekhona umda osezantsi.
• Iibher ezikwiingcambu zemisonto: Iibher ezibukhali ezishiywe sisixhobo sokusika esibuthuntu okanye idayisi egugileyo. Zinganqumla umsonto wokudibana ngexesha lokuhlanganiswa kwaye zidale iindawo zoxinzelelo ezikhawulezisa ukudinwa phantsi kokujikeleza okuphindaphindiweyo kobushushu. Uvavanyo olukhawulezileyo lwentsimi olusetyenziswa liqela lethu: sebenzisa ilaphu lekotoni ecaleni komsonto - ukuba iifayibha ziyabambeka, iibher ziyafumaneka.
• Ukugquma imisonto: Ugquma lwentsimbi okanye lwezinki olukhupha umsonto ngexesha lokwenziwa kwawo. Oku kuveza intsimbi esisiseko kwi-corrosion, nto leyo eyonyusa ukumelana kwamalungu ngokuhamba kwexesha. Sivavanya ukunamathela nge-bend-and-peel protocol kwibhetshi nganye.

Uluhlu Lokuhlola Lokwamkelwa Kwesampulu: Iprotokholi Yangaphakathi Yefektri Yethu

Xa omnye wabathengi bethu ecela isampulu yangaphambi kokuveliswa kwemveliso yethuIzihlanganisi zentonga yomhlaba ezinemisonto eyi-14.2mmokanye nayiphi na enye imveliso yokugquma enemisonto, sijonga uluhlu lwezinto ezilishumi elinambini. Ndabelana ngenxalenye ethile yemisonto apha kuba lelona candelo abathengi abaninzi abalibuzayo:

1. Ukuqinisekiswa kwefom yomsonto: Qinisekisa i-engile yomsonto (ii-degrees ezingama-60 ze-UNC/UNF/metric, ii-degrees ezingama-55 ze-BSP) usebenzisa i-optical comparator okanye i-thread gauge.
2. Ukulinganiswa kwepitch: Sebenzisa i-thread pitch gauge ukuqinisekisa ukuba i-TPI okanye i-mm pitch ihambelana nenkcazo. Kwi-5/8″-11 UNC, i-intshi nganye yobude be-thread kufuneka ibonise ngqo imisonto eli-11 epheleleyo.
3. Ububanzi obukhulu: Linganisa nge-micrometer kwiindawo ezimbini ezikude ngama-90 degrees. Zombini ii-readings mazibe ngaphakathi kwe-tolerance band yeklasi echaziweyo.
4. Ububanzi bepitshi: Sebenzisa i-thread micrometer okanye indlela ye-three-wire. Le yeyona nto ibonakalisa umgangatho we-thread.
5. Uvavanyo lwe-Go/no-go gauge: I-go gauge kufuneka idlule ngokukhululekileyo; i-no-go gauge mayingadluli ngaphezulu kweendlela ezimbini ezipheleleyo. Olu vavanyo lunye lubamba uninzi lweengxaki zobukhulu.
6. Uvavanyo lokulingana kokudibanisa: Hlanganisa intonga yesampulu ngesandla ngesixhobo sokudibanisa. Ilungu kufuneka lihlale ngokupheleleyo ngamandla aqinileyo njengeminwe kwaye kungabi ngaphezu kokujika kube kanye nesiqingatha ngesikrufu.
7. Ukuhlolwa okubonakalayo nokuchukumisayo: Jonga ukuba akukho ziqhuma, iziphene zeplati, kunye noburhabaxa bomphezulu. Abahloli bethu bafaka uzipho kumnwe phezu komsonto — kufuneka uzive uthambile kwaye ufana.
8. Uvavanyo lweTorque: Sebenzisa i-torque echaziweyo yokuhlanganisa (kwimveliso yethu, sichaza i-40-60 Nm kwi-5/8″-11 UNC ground rod coupling) kwaye siqinisekise ukuba ii-joint holds azinakususwa.

Kumgca wethu wemveliso, sithatha imifanekiso yokufundwa kwegauge yebhetshi nganye yesampulu kwaye siquke imifanekiso kwingxelo yokuhlolwa ethunyelwa nesampulu. Oku kucaca kube yenye yezizathu zokuba abathengi bethu kwicandelo lezonxibelelwano kunye neenkonzo zombane baqhubeke nokuchaza izinto zethu.iintonga zomhlaba ezifakwe imisonto zokudibanisa.

Izinto Eziqwalaselweyo: Indlela I-Base Metal Echaphazela Ngayo Ukusebenza Kwemisonto

Umsonto uthembeke kuphela njengezinto ezisikiweyo. Nantsi indlela izinto ezintathu zentonga yomhlaba esisebenza ngazo ezisebenza ngayo kumsonto:

Intsimbi Egqunywe Ngobhedu

Uninzi lwevolumu yethu lungena kwiiintonga zomhlaba ezigqunywe ngobheduUmaleko wobhedu (ngesiqhelo yi-0.254 mm okanye ubuncinci yi-0.508 mm) unika ukumelana nokugqwala kunye nokuqhuba, ngelixa umbindi wentsimbi unika amandla okuqhuba. Sifaka imisonto kwiintonga zethu emva kokuzigquma sisebenzisa ii-carbide-tipped rolling dies ezicinezela endaweni yokusika ubhedu, zigcina umaleko uqhubeka. Sicebisa abathengi ukuba bajonge ukuba ubhedu luyabonakala kwaye aluqhekekanga kwindawo yomsonto — intsimbi engenanto iya kugqwala, into esiyibonileyo kuhlolo lwentsimi emhlabeni kwiinyanga ezimbalwa.

Intsimbi Eshushu Ediphiweyo

Zethuiintonga zokugquma ezishushu ezigalelwe ngesinyithisebenzisaIntonga yomhlaba eqinisiweyo yentsimbi ye-Q235ulwakhiwo. Ingubo ye-zinc ifikelela kwi-50-80 microns ubuncinci kwi-ISO 1461 nganye, isetyenziswa ngokuntywilisela intonga egqityiweyo kwi-zinc enyibilikisiweyo. Kwimveliso yethu, umsonto uyasikwa emva kokufaka i-galvanizing, nto leyo eveza intsimbi engenanto eqongeni. Oku kuyamkeleka ukuba i-coupler nayo i-galvanised kwaye i-joint ivaliwe. Sikwabonelelaintonga yomhlaba egalelwe ngesinyithiiimveliso ezineendlela zokufaka imisonto ezifakwe i-galvanized.

Yenziwe ngentsimbi eshayinayo

Kwiindawo ezinomhlwa ophezulu — ukufakelwa konxweme, izityalo zeekhemikhali, okanye umhlaba onomxholo ophezulu we-chloride — sinikezelaiintonga zentsimbi engagqwaliyokwiigreyidi ezingama-304 kunye nama-316. I-Austenitic stainless work-iyenza lukhuni xa iqengqeleka, nto leyo enokunyusa ububanzi bepitch ngaphandle kokunyamezelana. Iqela lethu lobunjineli lihlawula inkqubo yokuqengqeleka ephindwe kabini kunye nokulinganisa phakathi kokuqengqeleka.

Izikhokelo zoFakelo lweSithili zeeNtonga zoQhagamshelo ezineMisonto

Kwanentonga efakwe imisonto egqibeleleyo inokungaphumeleli entsimini ukuba umfaki akalandeli indlela efanelekileyo. Ngokusekelwe kwingxelo evela kubathengi bethu nakwindwendwe zam zewebhusayithi, nazi iindlela zokusebenza ezinxulumene nokusebenza okuthembekileyo kwexesha elide:

• Coca imisonto ngaphambi kokuba ihlanganiswe. Umhlaba, uthuli, kunye nokupakisha inkunkuma kwimisonto kuya kuthintela ukudibana ngokupheleleyo kwaye kunokonakalisa umsonto. Ibhrashi eqinileyo kunye ne-wipe ngelaphu elicocekileyo kuthatha imizuzwana engamashumi amathathu kwaye kuthintela iiyure zokusombulula iingxaki.
• Lungelelanisa ngaphambi kokuba uqinise. Qala ukuhlanganisa ngesandla, ujikelezise intonga ngokwewotshi ngoxinzelelo oluthambileyo lwe-axial. Ukuba intonga ayijiki ngokukhululekileyo kwiinguqu zokuqala ezimbini ezipheleleyo, siyabuyela umva size silungelelanise kwakhona. Ukunyanzela umsonto ongalungelelananga kuya kuyihluba.
• Sebenzisa i-anti-oxidation compound kwiindawo ezigqunywe yi-copper. Sifaka umaleko omncinci we-anti-oxidation paste ehambelana ne-copper kumsonto ngaphambi kokuba siwuhlanganise ukuze sizalise ii-micro-voids kwaye sithintele ukungena komswakama okukhokelela kwi-galvanic corrosion kwindawo edibeneyo.
• Qhuba ngesando sokubetheka, hayi ngesando sokubetheka. Ukubetheka okuphindaphindiweyo kwesando sokubetheka kudala amaxesha okugoba kwindawo edibanisayo anokuqhekeza umsonto ogqunyiweyo. Isando esiqhuba intonga yomhlaba sinika amandla angqalileyo.
• Qinisekisa ukumelana nomhlaba emva kokufakela. Sebenzisa isixhobo sokuvavanya ukumelana nomhlaba (indlela yokuwa kwamandla nganye nganye)IEEE 81) ukuqinisekisa ukuba intonga efakiweyo iyahlangabezana nokumelana koyilo. Ukunyuka ngequbuliso kokumelana xa kuthelekiswa nentonga enecandelo elinye kunokubonisa ukuba umsonto awusebenzi kakuhle.

Umthengi wethu kumantla eKhanada usebenzise izixhobo zokucoca amagumbiiiseti zentonga zomhlabakunye nee-UNC couplings ezifikelela kwiimitha ezili-18 nge-permafrost. Ngokulandela i-alignment protocol engentla, abasebenzi badibene baza baqhuba amacandelo alishumi elinesibini eemitha ezili-1.5 ngaphandle kokusilela komsonto omnye kwaye baphumelela uvavanyo lokwamkelwa kwenkampani kumzamo wokuqala.

Indima yeMigangatho yeMisonto ekuThotyelweni kweNqanaba leNkqubo

Ngokwembono yethu, iinkqubo zokumisa umhlaba azikho zodwa. Ziyinxalenye yenkqubo iyonkeukhuseleko lombane kunye nombane ophantsiukufakelwa okufuneka kuhambelane neekhowudi zelizwe nezamazwe ngamazwe. Umgangatho wentambo kwi-ground rod coupler yakho ungabonakala ngathi yinkcazo encinci, kodwa unxibelelana nesakhelo esikhulu sokuthobela imithetho ngeendlela abahloli be-inshorensi nabahloli be-inshorensi abazijonga ngazo:

• I-IEEE 80 (ukufakwa komhlaba kwisitishi se-AC) — ifuna ukuqhubeka kombane. Ukunyamezelana kwamalungu ngaphandle kunokubangela ukuxhathisa okuyaphula oku. Isalathiso:IEEE 80.
• I-UL 467 (Izixhobo zokugquma kunye nokubopha) — I-UL ivavanya ii-electrode zokugquma ukuze ibone amandla oomatshini, ukuhanjiswa kwamandla, kunye nokumelana nokugqwala. Isixhumi esingaphumeleliyo kuvavanyo lwe-UL 467 asiyi kufumana luhlu. Isalathiso:UL.
• I-IEC 62561 (Iinxalenye zenkqubo yokukhusela umbane) — igubungela izihlanganisi, ii-conductors, kunye nee-electrodes zomhlaba. Icandelo lesi-7 lijongana ngqo nokugrumba komhlaba. Izihlanganisi ezinemisonto kufuneka ziphumelele uvavanyo loomatshini nolwe-elekthronikhi kulo mgangatho wokufakelwa kwe-LPS.
• Iikhowudi zombane zeSizwe (NEC, BS 7671, AS/NZS 3000) — uninzi lweekhowudi lufuna izinto ezidwelisiweyo zokumisa umhlaba. Isixhumi esingadweliswanga sinokubangela ukuba ukufakwa kungaphumeleli ekuhlolweni.

Kumsebenzi wam nabathengi bamanye amazwe, ndincede abantu abaninzi abafumene iintonga zomhlaba kubaboneleli abangazange baqinisekise imigangatho yemisonto, kodwa ndafumanisa ngexesha lophicotho ukuba abaqhagamsheli abahlangabezananga nemimiselo. Ukuphazamiseka kokuhlolwa kwakhona kunye nokuthengwa kwakhona kudlule kakhulu ixesha elithathwayo ukuqinisekisa ukunyamezelana kwemisonto kwinqanaba lesampulu. Ngenxa yokuba ukusilela kokuthobela imithetho kudla ngokudlula kwishedyuli yeprojekthi, ukufumana umsonto ochanekileyo kwisampulu yokuqala yenye yezona zenzo zibalulekileyo ezinokuthathwa yinjineli yokuthenga.

Indlela Esibaxhasa Ngayo Abathengi Ngenkqubo Yokuvunywa Kwesampuli

Xa ucela isampulu kwiziko lethu lokuvelisa — nokubaintonga yomhlaba yentsimbi egqunywe ngobhedu, i-coupling ene-galvanized, okanye i-intonga yentsimbi engagqwaliyo eneentambo— nantsi into esiyibonelelayo:

• Ingxelo yokuhlolwa enomlinganiselo wemisonto ethathwe kwiindawo ezintathu kubude bokudibanisa.
• Iifoto ezikufutshane zemisonto kwi-10x magnification zibonisa imeko ye-crest kunye nokuqhubeka kwe-plating.
• Izatifikethi zovavanyo lwezinto eziqinisekisa umgangatho wentsimbi esisiseko (ngesiqhelo yi-Q235 okanye elinganayo kwi-GB/T 700 nganye), uhlobo lwengubo, kunye nobukhulu bengubo.
• Ividiyo yovavanyo lokulingana kokudibanisa ebonisa ukuhlanganiswa kwesandla kunye nokusetyenziswa kwe-torque kwisampulu yokwenyani.
• Ukuba kuyimfuneko, singalungiselela uvavanyo lomntu wesithathu ngokusebenzisa iilabhoratri ezivunyiweyo ukuze siqinisekise okongezelelweyo.

Sigcina iigeyiji ezilinganisiweyo ze-UNC, UNF, BSP, kunye neefom zemisonto ye-metric kwilebhu yethu ye-QC. Abahloli bethu baqeqeshwe kwimigangatho efanayo nemigaqo yokulinganisa echazwe apha ngasentla, kwaye siphinda silinganise iigeyiji zethu rhoqo ngekota ngokuchasene nemigangatho ephambili elandelekayo.I-NISTokanye amaziko esizwe afanayo e-metrology.

Ukuba uvavanya umthengisi omtsha wentonga yokumisa umhlaba okanye ukuba ukhe waba neengxaki zokulingana nomxokelelwane nomthengisi wangoku, ndiyakukhuthaza ukuba uqale nge-odolo yesampulu evela kuthiizihlanganisi zentonga ezinemisontouluhlu.
