The standard does not cover forging stock (EN 603), nor does it apply to products in coils or coiled tubes supplied under the EN 13958 standard.<\/p>\n<h2>EN 754-2 Standard: Mechanical properties<\/h2>\n<p>This part of the standard defines the normative mechanical property indicators for cold-drawn aluminum rolled products (bars and tubes) used in various mechanical engineering sectors.<\/p>\n<h2>EN 754-3 Standard: Tolerances for round bars<\/h2>\n<p>This standard regulates the limit deviations of geometric parameters and shape for cold-drawn round bars and tubes. It applies to products with diameters ranging from 3 mm to 100 mm.<\/p>\n<h2>EN 754-4 Standard: Tolerances for square profiles<\/h2>\n<p>This standard establishes tolerances for dimensions and shape symmetry for cold-drawn square bars. The width range for products according to this standard is from 3 mm to 100 mm.<\/p>\n<h2>EN 754-5 Standard: Tolerances for rectangular bars<\/h2>\n<p>This standard defines requirements for the dimensional accuracy of rectangular aluminum alloy bars. It covers products with thicknesses from 2 to 60 mm and widths from 5 to 200 mm.<\/p>\n<h2>EN 754-6 Standard: Tolerances for hexagonal profiles<\/h2>\n<p>This standard details technical requirements for the manufacturing accuracy of cold-drawn hexagonal bars. It regulates rolled products with a width across flats from 3 mm to 80 mm.<\/p>\n<h2>EN 754-7 Standard: Seamless tubes<\/h2>\n<p>This standard regulates dimension and geometry tolerances for seamless tubes produced by cold deformation. The parameters cover round tubes with an outer diameter from 3 to 350 mm and shaped tubes with an inscribed circle diameter from 8 to 300 mm. The standard does not apply to products regulated by EN 754-8, nor to products in coils (EN 13958). The current edition, EN 754-7:2008, fully replaces the 1997 version.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[114],"class_list":["post-70112","wiki","type-wiki","status-publish","hentry","wiki_category-en"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70112","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki"}],"about":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/types\/wiki"}],"version-history":[{"count":0,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70112\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=70112"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=70112"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
