The technological requirements set forth in the standard are aimed at unifying product acceptance criteria, regardless of their size, nominal diameter (DN), or pressure rating (PN).<\/p>\n<p>As part of the certification testing, limit values for permissible internal leakage through the valve seat are established, as well as parameters for the tightness of external connections under conditions of extreme thermal exposure. The standard regulates equipment performance when exposed to an open flame for a 30-minute interval.<\/p>\n<p>The selection of a 30-minute fire exposure period is based on analytical data regarding the time required to localize and extinguish the majority of industrial fires at oil and gas infrastructure facilities. EV Group China emphasizes that these tests are critically important for confirming the fire safety of flow control systems in emergency situations that exceed the design parameters of standard operating loads.<\/p>\n","protected":false},"featured_media":0,"template":"","meta":[],"wiki_category":[111],"class_list":["post-69659","wiki","type-wiki","status-publish","hentry","wiki_category-api"],"_links":{"self":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki\/69659","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\/69659\/revisions"}],"wp:attachment":[{"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/media?parent=69659"}],"wp:term":[{"taxonomy":"wiki_category","embeddable":true,"href":"https:\/\/evgroupchina.com\/en\/wp-json\/wp\/v2\/wiki_category?post=69659"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
