The dimensional specifications of products follow ISO 1101 (geometrical tolerances), ISO 286 (ISO tolerances), EN 10220 for tubes and ISO 6892 for metallic materials.

A correctly sized system not only reduces scrap and increases productivity, but also generates process data that feeds company analytics systems and enables predictive maintenance strategies. The technological choice should always be validated by a feasibility study on the real sample, including MSA (Measurement System Analysis), Gage R&amp;R and calculation of the expanded uncertainty in accordance with the GUM.  <\/p>\n\n\n\n<div class=\"wp-block-group rd-ovalita is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">What ovality is and how it is measured <a class=\"roder-up\" href=\"#\" title=\"Back to top\" aria-label=\"Torna all&#x2019;inizio della pagina\">\u2191 up<\/a><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Ovality<\/strong> is the deviation of the cross-section of a cylindrical body (tube, bar, wire, ring, bore) from the ideal circle.

In relative form, used by many product standards for tubes and profiles, <strong>Ovality % = (D<sub>max<\/sub> \u2212 D<sub>min<\/sub>) \/ D<sub>nom<\/sub> \u00d7 100<\/strong>, where D<sub>nom<\/sub>
