This standard regulates sampling procedures and product quality verification, ensuring full compliance with the stated technical indicators.<\/p>\n<p>The EN 1982 standard applies to the following categories of products supplied by EV Group China:<\/p>\n<ul>\n<li><strong>Copper alloy ingots:<\/strong> raw material billets intended for subsequent remelting and the manufacturing of high-precision castings.<\/li>\n<li><strong>Finished copper and alloy castings:<\/strong> products that do not require additional machining. The production technology includes sand casting, centrifugal casting, continuous casting methods, and permanent mold casting.<\/li>\n<\/ul>\n<p>To optimize design and procurement processes, EV Group China recommends referring to Annex A for the formation of order specifications. Additional test protocols and non-destructive testing methods for ingots are described in detail in Annex B, allowing engineers to guarantee the reliability of products in critical equipment assemblies.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[114],"class_list":["post-70045","wiki","type-wiki","status-publish","hentry","wiki_category-en"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/70045","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\/70045\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=70045"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=70045"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
