standardtolerantsijärk
  • ühise tunnusega iseloomustatud joonmõõtmete standardtolerantside grupp
  • group of tolerances for linear sizes characterized by a common identifier
standardtolerantsijärk
Usage examples
  • Standardtolerantsijärk on sama täpsuse määraga ISO tolerantside kogum, nt IT7 (IT = standardtolerants, 7 = järgu number)
tolerantsijärk
Usage examples
  • ISO tolerantsisüsteemis on 20 tolerantsijärku, mida tähistatakse tähisega IT (International Tolerance) koos järgneva numbriga IT01, IT1, IT2, ... IT18, ning seda tolerantsi suurenemise (täpsuse kahanemise) järjekorras.
standard tolerance grade
Usage examples
  • In the ISO code system for tolerances on linear sizes, the standard tolerance grade identifier consists of IT followed by a number (e.g. IT7). A specific tolerance grade is considered as corresponding to the same level of accuracy for all nominal sizes.

standardtolerantsi järk preferred
Usage examples
  • ISO joonmõõtmete tolerantside koodsüsteemis standardtolerantsi järgu tunnus sisaldab IT koos järgneva numbriga (nt IT7), seejuures kindel standardtolerantsi järk arvestab vastavalt sama taseme täpsusnõudeid kõikidele nimimõõtmetele.
