I-DIN, i-JIS, i-GB, i-ASME: Umhlahlandlela Owusizo Wezindinganiso Zepuleti Lomphezulu We-Granite

Abathengi abaqhathanisa amapuleti obuso be-granite avela kubahlinzeki abahlukene bavame ukubhekana nenkinga ethule: amapuleti amabili angasho ukuthi “iBanga 0″ noma “iBanga AA” kodwa angasho into efanayo, ngoba abhekisela ezindinganisweni ezahlukene zikazwelonke ezinamafomula ahlukene okubekezelelana. Lo mhlahlandlela uchaza ukuthi izindinganiso ezinkulu zichaza ini ngempela nokuthi kungani umehluko ubalulekile lapho uthenga imishini.

Kungani kungekho indinganiso eyodwa yomhlaba wonke

Amapuleti obuso be-granite alinganiswa ngokumelene nokubekezelelana okuyisicaba okulingana nosayizi wepuleti — ipuleti elingu-1600mm kanye nepuleti elingu-300mm ngokusobala alikwazi ukuthwala ukubekezelelana okufanayo okuphelele. Amazwe ahlukene athuthukise amafomula awo alokhu kulinganisa, ngokuvamile enkathini efanayo yokumiswa kwezimboni:

• IJalimane — I-DIN 876 cishe iyindinganiso ebhekiswa kakhulu emhlabeni wonke, ichaza amamaki okunemba angu-00, 0, 1, kanye no-2, kanti ibanga elingu-00 yilona eliqinile kakhulu. I-geometry yamathuluzi e-granite ahlobene nesembozo se-DIN 875 kanye ne-DIN 650.
• I-United States — I-Federal Standard GGG-P-463c kanye ne-ASME B89.3.7 yesimanje ichaza amamaki AA, A, kanye no-B amapuleti angaphezulu, ngokomlando amalabhorethri amaningi e-metrology aseMelika kanye nezitolo zemishini ezilinganisa ngokumelene nawo.
• IJapan — I-JIS B 7513 isetha uhlelo lwayo lwezinga, oluvame ukubhekiselwa kumishini eyakhelwe noma ethunyelwe kubakhiqizi baseJapan, ikakhulukazi ochungechungeni lokuphakelwa kwe-semiconductor.
• IShayina — amazinga e-GB/T, asondelene kakhulu nezindinganiso zomhlaba wonke eminyakeni yamuva nje njengoba imishini yokunemba eyenziwe eShayina iqhubeka nokusebenzela izimakethe zokuthumela kwamanye amazwe.
• I-United Kingdom — BS 817, iRussia — GOST 10905, kanye neFrance — amazinga e-NF agcwalisa uhlu lwezindinganiso ezisabhekiselwa kuzo ngokuya ngezwe lapho imishini ivela khona noma lapho iya khona.

Yini ngempela ehluke phakathi kwabo

Ukungavumelani okuyinhloko phakathi kwezindinganiso akusiyo ifilosofi — yifomula yezibalo esetshenziswa yilowo nalowo ukubala ukuphambuka okuphezulu okuvunyelwe kokusicaba ngokusekelwe kubude obuqondile bepuleti. Ipuleti le-DIN 876 leBanga 0 kanye nepuleti le-JIS leBanga 1 lobukhulu obufanayo kungagcina ngokubekezelelana okuseduze kodwa okungafani. Eziningi zezicelo zezimboni umehluko awubalulekile. Kumalabhorethri e-metrology enza ukulinganisa okulandelekayo, noma imishini eyenzelwe ikhasimende elidinga isitifiketi se-DIN noma se-JIS ngokusobala, akunjalo.

Yingakho, lapho kutholakala khonaizingxenye ze-graniteUma kuthengwa kwamanye amazwe, kubalulekile ukubuza umhlinzeki ukuthi isitifiketi sokulinganisa sibhekisela kuyiphi indinganiso - hhayi nje ukuthi yiliphi inombolo yebanga elivela emaphepheni. Isimangalo "sebanga 0" esingenalo indinganiso eqanjwe ngegama asikwazi ukuqinisekiswa.

Ukulandelela: ingxenye okulula ukuyidlula

Isitifiketi sokulinganisa sithembekile kuphela njengeketanga elingemuva kwaso. Ithuluzi elisetshenziselwa ukukala ipuleti — izinga le-elekthronikhi, i-autocollimator, i-laser interferometer — kufanele ngabe lilinganiswe yisikhungo se-metrology esigunyaziwe, futhi lokho kulinganisa kufanele kulandelelwe emuva esimisweni esiyinhloko sikazwelonke. Empeleni, lokhu kusho ukucela:

1. Isitifiketi sokulinganisa sepuleti noma ingxenye ethile, esho ukuthi iyiphi indinganiso (i-DIN/JIS/GB/ASME/njll.) esetshenzisiwe.
2. Isitifiketi sokulinganisa sethuluzi lokulinganisa elisetshenzisiwe, esikhishwe yisikhungo se-metrology esiqashelwayo.
3. Isitatimende esicacile sokungaqiniseki kokulinganisa, hhayi nje ibanga lokuphasa/lokwehluleka.

Okungashiwongo ngalolu chungechunge yindlela izimangalo "eziqinisekisiwe zeBanga 0" ngezinye izikhathi eziziveza ngayo ukuthi zikhishwe yifektri ngaphandle kokuqinisekiswa okuvela eceleni nhlobo - empeleni akuyona inkohliso, kodwa futhi ayinayo inhloso ezimele.

Inothi eliwusizo lamaqembu okuthenga

Uma imishini yakho ihloselwe izimakethe eziningi zokuthumela kwamanye amazwe, ngokuvamile kufanelekile ukucela ukulinganiswa okubili — isibonelo, kokubili izibalo ze-DIN 876 kanye ne-JIS B 7513 — kunokucabanga ukuthi indinganiso eyodwa ihumusha kahle kwenye. Kubiza kakhulu ngesikhathi sokulinganisa, kodwa kususa ukungaqondakali kumakhasimende okugcina, ikakhulukazi ezimbonini ezifana nokukhiqiza izimoto ze-semiconductor kanye nezimoto lapho umnyango wekhwalithi womthengi wokugcina uzocela imibhalo ethile ejwayelekile.
