What is DIN ISO 2768?
What is ISO 2768-mK Meaning? An ISO 2768-mK mark means the dimension information for which the tolerances are not specified will be followed according to the m and K class. m class is specified in ISO 2768-1 and K class is specified in ISO 2768-2, which including H, K, and L tolerance levels.
What is ISO Fullform?
International Organization for StandardizationInternational Organization for Standardization / Full name

What is DIN ISO 2768-1 tolerance?
ISO 2768 – m or general tolerance ISO 2768 – m For new designs only the general tolerance according to DIN ISO 2768-1 should be valid. The limit measurements of the tolerance classes m and f of DIN ISO 2768-1 are identic with those of DIN 7168-1. According to DIN ISO 2768-2
What does ISO 2768-mk mean?
Therefore, ISO 2768-mK means that such a component must meet the “medium” tolerance range for Part 1 and the tolerance class “K” for Part 2. Other tolerance levels in Part 1 are fine, coarse, and very coarse, while those in Part 2 include H, K, and L.
What is Din 2768-2 used for?
According to DIN ISO 2768-2 DIN ISO 2768-2 is for simplifying drawing and fixes general tolerances in three tolerance classes for form and position. By choosing a special tolerance class exactly the precision level common in workshops should be taken into account.
Which tolerance is used for variation in dimension without tolerance?
Therefore variation in dimension without tolerance is defined using general tolerance. ISO 2768 has defined general tolerance for: Geometric Tolerance such as straightness, flatness, perpendicularity, symmetry and runout. We suggest you read this article on go no-go gauges.
