Sibe namakhasimende asithumelele isitifiketi sokulinganisa ipuleti angalithenganga kithi, ebuza ukuthi libukeka lilungile yini ngaphambi kokuba asayine ukuhlolwa okuzayo. Ngokuvamile, isitifiketi sinesitembu, usuku, kanye nomphumela wokupasa/wokwehluleka — futhi akukho lutho olukutshela ukuthi izinombolo zivelaphi. Leso yisikhala abantu abaningi abangazi ukuthi basibheke kuze kube yilapho othile ebacela ukuthi bavikele amarekhodi abo okulinganisa kumhloli wezincwadi noma kumakhasimende.
Isitifiketi asilandeleki ngoba sinesiginesha kanye nelogo kuso. Silandeleki ngenxa yochungechunge oluthile lokugcinwa ngemuva kwezinombolo, futhi lolo chungechunge luyahlolwa uma wazi ukuthi yini okufanele uyibheke.
Okushiwo yi-“trackable” empeleni
Ukulandelela kusho ukuthi inani elisesitifiketini sepuleti lakho lingaxhunywa, ngochungechunge olunganqamuki lokulinganisa, libuyele esilinganisweni sokulinganisa sikazwelonke noma samazwe ngamazwe — ngokungaqiniseki okubhaliwe kuzo zonke izixhumanisi kulolo chungechunge. Isixhumanisi ngasinye sibalulekile: ithuluzi elilinganise ipuleti lakho lalinganiswa ngokwalo ngokumelene nereferensi, lelo referensi lalinganiswa ngokumelene nezindinganiso zezinga eliphezulu, njalonjalo kuze kufike esikhungweni sikazwelonke se-metrology.
Uma kukhona isixhumanisi kulolo chungechunge esingekho — ithuluzi elilinganiswe ngaphakathi endlini ngaphandle kokulandelela lutho, noma isitifiketi esingasho ukuthi yiliphi izinga eliphakeme elisetshenzisiwe — uchungechunge luphukile, futhi inombolo esesitifiketini sakho, noma ngabe ibukeka inembile kangakanani, ayilandeleki kunoma yini yangaphandle. Kungase kube yiqiniso. Awukwazi ukukufakazela lokhu kusuka emaphepheni kuphela.
Izinto ezinhlanu okufanele uzihlole ngempela esitifiketini
1. Ngubani owasikhipha, futhi ngokumelene nani. Isitifiketi kufanele siqambe ilabhorethri yokulinganisa, futhi kufanele sisho ukugunyazwa kwayo (i-ISO/IEC 17025 iyindinganiso efanele yamalabhorethri okulinganisa ikakhulukazi - isitifiketi esijwayelekile se-ISO 9001 kuwebhusayithi yenkampani asifani futhi asimbozi ukulandelelwa kokulinganisa). Imishini yethu yokulinganisa ilinganiswa ngezikhungo zesifundazwe saseJinan naseShandong, kanye nochungechunge olufinyelela ezinkombeni zesikhungo sikazwelonke sokulinganisa - uma isitifiketi osifundayo singasho igama lomzimba ofanayo, buza.
2. Usuku, kanye nesikhathi sokusebenza. Ukulinganiswa yisitatimende mayelana nethuluzi noma ipuleti ngosuku elinganiswe ngalo, hhayi impahla ehlala njalo. Hlola usuku lokulinganiswa ngokuhambisana nezidingo zakho zesikhathi sokuqinisekiswa kabusha, bese uhlola ukuthi isitifiketi sisho yini isikhathi esinconywayo nhlobo - isitifiketi esingenaso isikhathi esishiwo asikutsheli lutho ngokuthi kufanele uphinde uhlolwe nini.
3. Ukungaqiniseki okushiwoyo, hhayi nje umphumela wokuphasa/wokwehluleka. Lena yinto abantu abayiqayo kaningi. Isitifiketi esithi “Ibanga 0, PASS” sikutshela ukuthi ipuleti lihlangane nebhendi yokubekezelelana ngosuku lokulinganisa. Asikutsheli ukuthi lokho kulinganisa kwakuqinisekile kangakanani. Isitifiketi esifanele sisho ukungaqiniseki kokulinganisa (ngokuvamile kubhalwa njengo-± inani elithile elinesici sokumboza, ngokuvamile i-k=2 cishe ngokuqiniseka okungu-95%) eceleni komphumela. Uma ukubekezelela kwakho inqubo kuseduze nokubekezelelana okushiwo yipuleti, ukungaqiniseki kokulinganisa yinombolo ekutshela ukuthi ngabe “PASS” empeleni inomkhawulo kuyo noma ilungile emaphethelweni.
4. Indlela yokulinganisa kanye nethuluzi elisetshenzisiwe. Isitifiketi kufanele sisho ukuthi yini ngempela eyasetshenziswa ukukala ipuleti — indlela ye-elekthronikhi yezinga kanye negridi, i-interferometer, ukuqhathanisa ipuleti lokubhekisela — futhi okungcono kakhulu inkomba yokulinganisa yethuluzi. Izindlela ezahlukene zinokungaqiniseki okuhlukile okungafinyeleleka, futhi inombolo ye-flatness ngaphandle kwendlela eshiwo kunzima ukuyihlola ngokwezidingo zakho.
5. Izimo zemvelo ngesikhathi sokulinganisa. Izinga lokushisa okungenani, futhi okungcono kakhulu umswakama, kufanele lirekhodwe, ngoba i-granite kanye nezinsimbi zokulinganisa zombili zisabela ekushiseni. Isitifiketi sokuba yisicaba esikhishwe ku-30°C sepuleti elizosebenza ku-20°C asilona iphutha ngokuzenzakalelayo, kodwa isitifiketi kufanele okungenani sikutshele izimo ukuze ukwazi ukwahlulela ukuthi ziseduze ngokwanele yini nendawo yakho yokusebenza ukuze zibe nenjongo ngaphandle kokulungiswa.
Kungani lokhu kubaluleke ngaphezu kwalokho abantu abakucabangayo kuze kube yilapho kungabalulekile
Sasinodaba lapho uhlelo lwekhwalithi yekhasimende luhlolwa khona, futhi umhloli wamabhuku wacela ukuba bakhiqize uchungechunge lokulandelela ngemuva kwesitifiketi sokulinganisa somhlinzeki semishini enikeza inqubo yokulinganisa ebhekene nekhasimende. Isitifiketi esisefayilini sasithi “silinganisiwe” nosuku kanye nesiginesha — akukho lab egunyaziwe eqanjwe igama, akukho ukungaqiniseki okushiwoyo, akukho ndlela eqoshiwe. Kwakungekhona ukuthi ipuleti lalingalungile. Kwakuwukuthi kwakungekho ndlela yokubonisa ukuthi lilungile, ephepheni, lapho othile ebuza. Leyo yindleko yangempela yesitifiketi esingalandeleki: akuyona indlela yokulinganisa embi, kodwa umbuzo ongaphenduleki ngesikhathi esibi kakhulu.
Lokho izitifiketi zethu ezikuphethe
Yonke into yokulinganisa esiyisebenzisayo — izinkomba zokudayela ze-Mahr kusisombululo esingu-0.5 µm, ama-Mitutoyo gauges, amazinga kagesi e-WYLER, ama-interferometer e-laser e-Renishaw — ilinganiswa ngokwesheduli ngezikhungo ze-metrology zaseJinan naseShandong, kanye nochungechunge olulandelekayo ngokwezindinganiso zezikhungo ze-metrology zikazwelonke. Uma sikhipha isitifiketi sokulinganisa ngepuleti, sisho into kanye nendlela esetshenzisiwe, amanani alinganisiwe, izimo zemvelo ngesikhathi sokulinganisa, kanye nereferensi yokulinganisa yento ngokwayo, hhayi nje isitembu esithi ipuleti lidlulile. Uma uhlelo lwekhwalithi yekhasimende ludinga isethi ephelele yedokhumenti yokulandelela kunesitifiketi esifingqiwe, singakunikeza lokho uma siceliwe — yidatha efanayo eyisisekelo, evezwa nje ezingeni lemininingwane edingwa ukuhlolwa.
Uma ungadingi ukungena ujule kangaka
Uma ipuleti lisetshenziselwa umsebenzi wokubhekisela esitolo lapho ukuhlolwa okunzima kokuhamba/ukungahambi kuyikona okubalulekile — ukuhlola ukuthi into efakwe izintambo ihlala phansi, isibonelo, kunokunikeza inqubo yokulinganisa eqinisekisiwe — isitifiketi sokudlula/ukwehluleka esiyisisekelo esinosuku cishe sanele, futhi ukucela umhlinzeki iphakheji ephelele yokulandelela ye-ISO/IEC 17025 yalolo hlelo lokusebenza kuyiphepha elingaphezu kwezidingo zomsebenzi. Imibhalo yokulandelela ikhona ukuze iphendule umbuzo othize — ungawufakazela yini lo mbhalo, kubani, futhi ngaphansi kwaliphi izinga — futhi uma kungekho muntu ozokubuza lowo mbuzo, imininingwane eyengeziwe ibiza isikhathi ngaphandle kokukuthengela noma yini.
Lapho kubalulekile khona yilapho ikhasimende lakho, umhloli wakho wezimali, noma inhlangano yakho yezitifiketi izokugcina ikucele ukuthi ubonise ukuthi inombolo ivelaphi. Uma ungaqiniseki ukuthi isicelo sakho sikuleso sigaba, lokho ngokuvamile kuyisibonakaliso sokuthi sikhona.
Isinyathelo esilandelayo
Uma ucacisa ipuleti noma ingxenye entsha futhi udinga ukwazi kahle ukuthi isitifiketi sakho sokulinganisa sizofaka ini ngaphambi kokuthi u-ode, sicele isitifiketi sesampula sosayizi kanye nebanga olicabangayo. Uma usuvele unepuleti elisebenzayo futhi ungaqiniseki ukuthi isitifiketi salo esikhona singalandeleka yini, sithumele — singakutshela ukuthi yini engekho nokuthi kufanelekile yini ukuthi liqinisekiswe kabusha ngokumelene nochungechunge olubhalwe phansi.
