Siye safumana abathengi abasithumelela isatifikethi sokulinganisa ipleyiti abangazange bayithenge kuthi, bebuza ukuba ibukeka ilungile na ngaphambi kokuba basayine uvavanyo oluzayo. Rhoqo, isatifikethi sinesitampu, umhla, kunye nesiphumo sokupasa/sokungaphumeleli — kwaye akukho nto ikuxelela ukuba amanani avela phi. Elo lithuba abantu abaninzi abangaziyo ukuba balijonge de umntu abacele ukuba bakhusele iirekhodi zabo zokulinganisa kumphicothi-zincwadi okanye kumthengi.
Isatifikethi asilandeleki kuba sinesiginitsha kunye nelogo kuso. Silandeleki ngenxa yoluhlu oluthile lokugcina emva kwamanani, kwaye olo luhlu lunokutshekishwa ukuba uyazi ukuba ujonge ntoni.
Oko kuthethwa ligama elithi “ukulandeleka” ngokwenene
Ukulandelelana kuthetha ukuba ixabiso elikwisatifikethi sepleyiti yakho lingaqhagamshelwa, ngomxokelelwane ongaqhekekanga wokulinganisa, libuyele kumgangatho wokulinganisa wesizwe okanye wehlabathi — kunye nokungaqiniseki okubhaliweyo kuyo yonke ikhonkco kuloo mxokelelwane. Ikhonkco ngalinye libalulekile: isixhobo esilinganise ipleyiti yakho sona silinganiswe ngokuchasene nesalathiso, eso salathiso silinganiswe ngokuchasene nomgangatho ophezulu, njalo njalo ukuya kwiziko lesizwe le-metrology.
Ukuba kukho naliphi na ikhonkco kuloo tyathanga elingekhoyo — isixhobo esilinganiswe ngaphakathi endlwini ngaphandle kwento enokulandeleka, okanye isatifikethi esingatshoyo ukuba yeyiphi imigangatho ephezulu esetyenzisiweyo — ityathanga liphukile, kwaye inombolo ekwisatifikethi sakho, nokuba ibukeka ichanekile kangakanani na, ayilandeleki kuyo nayiphi na into yangaphandle. Isenokuba ichanekile. Awunakukwazi ukukungqina oko usebenzisa amaphepha kuphela.
Izinto ezintlanu ekufuneka uzijonge kwisatifikethi
1. Ngubani osikhuphe, kwaye ngokuchasene nantoni na. Isatifikethi kufuneka sibize ilabhoratri yokulinganisa, kwaye kungcono sichaze ukuqinisekiswa kwayo (i-ISO/IEC 17025 ngumgangatho ofanelekileyo weelabhoratri zokulinganisa ngokukodwa - isiqinisekiso se-ISO 9001 esiqhelekileyo kwiwebhusayithi yenkampani asiyonto ifanayo kwaye asigubungeli ukulandeleka kokulinganisa). Izixhobo zethu zokulinganisa zilinganiswa ngeZiko leMetrology lephondo laseJinan naseShandong, kunye nochungechunge olufikelela kwiireferensi zeZiko leMetrology lesizwe - ukuba isatifikethi osifundayo asibizi mzimba ofanayo, buza.
2. Umhla, kunye nexesha lokusebenza. Ukulinganiswa sisitatimende malunga nesixhobo okanye ipleyiti ngomhla esalinganiswa ngawo, kungekhona ipropati esisigxina. Jonga umhla wokulinganiswa ngokweemfuno zakho zexesha lokuqinisekiswa kwakhona, kwaye ujonge ukuba isatifikethi sichaza ixesha elicetyiswayo na kwaphela - isatifikethi esingenalo ixesha elichaziweyo asikuxeleli nto malunga nokuba kufuneka uphinde uhlolwe nini.
3. Ukungaqiniseki okuchaziweyo, kungekuphela nje kwesiphumo sokupasa/sokungaphumeleli. Le yeyona nto abantu bayitsiba rhoqo. Isatifikethi esithi “Ibanga 0, PASS” sikuxelela ukuba ipleyiti idibene nebhendi yokunyamezelana ngomhla wokulinganisa. Asikuxeleli ukuba olo mlinganiselo wawuqinisekile kangakanani. Isatifikethi esifanelekileyo sichaza ukungaqiniseki komlinganiselo (kudla ngokubhalwa njenge ± ixabiso elithile eline-coverage factor, edla ngokuba yi-k=2 malunga nokuzithemba okungama-95%) ecaleni kwesiphumo. Ukuba ukunyamezelana kwenkqubo yakho kusondele ekunyamezeleni okuchaziweyo kwepleyiti, ukungaqiniseki komlinganiselo linani elikuxelela ukuba ingaba “PASS” inomda kuyo okanye ilungile na.
4. Indlela yokulinganisa kunye nesixhobo esisetyenzisiweyo. Isatifikethi kufuneka sichaze ukuba yintoni esetyenzisiweyo ukulinganisa ipleyiti — indlela ye-elektroniki yenqanaba kunye negridi, i-interferometer, uthelekiso lwepleyiti yesalathiso — kwaye ngokuqinisekileyo isalathiso sokulinganisa sesixhobo. Iindlela ezahlukeneyo zinezimvo ezahlukeneyo ezinokufezekiswa, kwaye inani le-flatness elingenayo indlela echaziweyo kunzima ukulivavanya ngokweemfuno zakho.
5. Iimeko zendalo ngexesha lokulinganisa. Ubushushu obuncinci, kwaye ngokufanelekileyo, kufuneka burekhodwe, kuba igranite kunye nezixhobo zokulinganisa zombini ziyasabela kubushushu. Isatifikethi sokutyibilika esikhutshwe kwi-30°C sepleyiti eza kusebenza kwi-20°C asichanekanga ngokuzenzekelayo, kodwa isatifikethi kufuneka ubuncinane sikuxelele iimeko ukuze ukwazi ukugweba ukuba zikufutshane ngokwaneleyo na kwindawo yakho yokusebenza ukuze zibe nentsingiselo ngaphandle kokulungiswa.
Kutheni oku kubaluleke ngaphezu kokuba abantu becinga de kube yinto engabalulekanga?
Sasikhe sajongana nemeko apho inkqubo yomgangatho yomthengi yayihlolwa, waza umphicothi-zincwadi wabacela ukuba bavelise uthotho lokulandelela emva kwesatifikethi sokulinganisa somthengisi sezixhobo ezondla inkqubo yokulinganisa ejongene nomthengi. Isatifikethi esikwifayile sasithi “silungisiwe” kunye nomhla kunye notyikityo — akukho labhoratri ivunyiweyo ekhankanyiweyo, akukho kungaqiniseki kuchazwe, akukho ndlela ibhaliweyo. Kwakungekuko ukuba ipleyiti yayingalunganga. Yayikukuba kwakungekho ndlela yokubonisa ukuba ichanekile, ephepheni, xa umntu ebuza. Elo lixabiso lokwenyani lesatifikethi esingalandelekiyo: ayilomlinganiselo ombi, kodwa ngumbuzo ongaphendulekiyo ngexesha elibi kakhulu.
Oko sikuphetheyo kwizatifikethi zethu
Zonke izixhobo zokulinganisa esizisebenzisayo — izikhombisi ze-Mahr dial kwisisombululo se-0.5 µm, ii-Mitutoyo gauges, amanqanaba e-elektroniki e-WYLER, ii-interferometers ze-laser ze-Renishaw — zilinganiswa ngokweshedyuli ngokusebenzisa i-Jinan kunye ne-Shandong metrology institutes, kunye ne-chain elandelekayo ngokwemigangatho ye-national metrology institute. Xa sikhupha isatifikethi sokulinganisa ngepleyiti, sichaza isixhobo kunye nendlela esetyenzisiweyo, amaxabiso alinganisiweyo, iimeko zokusingqongileyo ngexesha lokulinganisa, kunye nesalathiso sokulinganisa sesixhobo ngokwaso, kungekhona nje isitampu esithi ipleyiti idlulile. Ukuba inkqubo yomgangatho yomthengi ifuna iseti epheleleyo yoxwebhu lokulandelela endaweni yesatifikethi sesishwankathelo, singakunika oko xa uceliwe — yidatha efanayo esisiseko, evezwa kwinqanaba leenkcukacha ezifunwayo luhlolo.
Xa ungadingi ukuya nzulu kangaka
Ukuba ipleyiti isetyenziselwa umsebenzi wokujonga umgangatho wevenkile apho ukujonga okungafunekiyo/okungangeniyo kuphela okubalulekileyo - ukujonga ukuba isixhobo sihleli tyaba, umzekelo, endaweni yokondla inkqubo yokulinganisa eqinisekisiweyo - isatifikethi esisisiseko sokupasa/sokungaphumeleli esinomhla mhlawumbi sanele, kwaye ukucela umthengisi iphakheji epheleleyo yokulandelela ye-ISO/IEC 17025 kweso sicelo kungaphezulu kwamaphepha kunokuba umsebenzi ufuna. Amaxwebhu okulandelela akhona ukuphendula umbuzo othile - ungawungqina na lo manani, kubani, kwaye phantsi kowuphi umgangatho - kwaye ukuba akukho mntu uza kubuza loo mbuzo, iinkcukacha ezongezelelweyo zibiza ixesha ngaphandle kokukuthengela nantoni na.
Apho kubalulekile khona kukuba umthengi wakho, umphicothi-zincwadi wakho, okanye umbutho wakho weziqinisekiso uya kukucela ekugqibeleni ukuba ubonise apho inombolo ivela khona. Ukuba awuqinisekanga ukuba isicelo sakho sikulo luhlu, oko kudla ngokuba luphawu lokuba kunjalo.
Inyathelo elilandelayo
Ukuba uchaza ipleyiti entsha okanye into ethile kwaye ufuna ukwazi kakuhle ukuba iza kuquka ntoni isatifikethi sakho sokulinganisa ngaphambi kokuba u-odole, cela isampulu yesatifikethi sobungakanani kunye nenqanaba ocinga ngalo. Ukuba sele unepleyiti esebenzayo kwaye awuqinisekanga ukuba isatifiketi sayo esikhoyo sinokulandeleka na, sithumelele — singakuxelela ukuba yintoni engekhoyo kwaye nokuba kufanelekile na ukuba siqinisekiswe kwakhona ngokuchasene nekhonkco elibhaliweyo.
