JIS G4305: 2015 specifies Ntev ntev kev pab rau sus304 stainless hlau hloov cov tuav raws txoj kev tsim khoom thiab ntev:
Kub - rolled tuav (ntev 2-6 m): ±50 mm tolerance for lengths ≤3 m; ±75 mm for lengths >3 m. Cov xoob xoob cov kev pab cuam tshuam rau qhov chaw ncua ntev tsis yog qhov tseem ceeb (piv txwv li, cov qauv kev txhawb nqa).
Txias - Kos cov tuav (ntev 1-6 m): ±10 mm tolerance for lengths ≤3 m; ±15 mm for lengths >3 m. Siv lub ntsuas hluav taws xob nyem (piv txwv li, hom sharoftive).
Txiav - rau - ntev tuav: Custom lengths (e.g., 1.2 m, 4.5 m) have a tolerance of ±3 mm for lengths ≤2 m; ±5 mm for lengths >2 m, zoo tagnrho rau cov ntawv thov uas xav tau tsawg ntawm-}} qhov chaw ntsuas kev tsim khoom, nrog tsis ua raws li kev txiav lossis tsis lees txais. Kev thev ua kom tau raws li qhov sib xyaw nrog cov khoom ua ntej thiab txo cov khib nyiab thaum nruab.
