What are UL E-Files?<\/h2>\n\n

UL assigns an E-File<\/strong> or UL File Number<\/strong> to each product or product group from a manufacturer, which can be used to identify the product and locate it in UL\u2019s database<\/a>. Colloquially, one could refer to this as a type of registration number. <\/p>\n\n

What does an e-file from UL look like?<\/h2>\n\n

An E-File or UL File Number typically consists of the letter E<\/strong> followed by a six-digit number<\/strong>. For our UL 508A-certified control cabinets, this is, for example, the number E474762, as you can see in the excerpt below from the Confirmation Letter from UL.<\/p>\n\n

A database for all UL e-files<\/h3>\n\n

It\u2019s easy to find out which manufacturer<\/strong>, product, and <\/strong> UL standard <\/strong>a specific UL File Number refers <\/strong>to. UL Solutions provides all relevant information in its UL Product iQ<\/em> database (formerly known as the Online Certifications Directory<\/em>). The corresponding data sheet<\/strong> (also known <\/em>as a Yellow Card <\/em>) for the relevant E-File Number is also available there. A user account is required to access this data. <\/p>\n\n

The Importance of E-Files in Practice<\/h2>\n\n

A UL File Number on a product does not<\/strong>, in and of itself, prove<\/strong> that the product has actually been certified by UL. Only the corresponding UL certificate<\/a> can provide that assurance. The label is therefore often the first thing noticed by end customers, consumers, and inspectors from the Authority Having Jurisdiction<\/a> (AHJ). However, the E-File offers a simple and secure way to access the relevant data sheets. <\/p>\n\n

The E-File is usually easy to find because, if available, it appears along with the Category Code Number (CCN<\/a>) on the product’s nameplate<\/strong> or can be found on the UL label itself.<\/p>\n\n

Zusammenfassung<\/strong><\/h2>

UL E-Files<\/strong> are product-specific identifiers that can be used to trace a UL-certified product back to its manufacturer. Using the E-File, the corresponding data sheet containing <\/strong>information about the product and its certification can be found in the UL Product iQ<\/em> database. They also indicate which UL standard<\/strong> the product was tested against.<\/p><\/p>\n","protected":false},"author":4,"featured_media":12756,"template":"","categories":[163],"tags":[165,169,164,174],"class_list":["post-12755","wiki","type-wiki","status-publish","has-post-thumbnail","hentry","category-ul-wiki","tag-certification","tag-standard","tag-ul","tag-ul-database"],"_links":{"self":[{"href":"https:\/\/krayer.de\/en\/wp-json\/wp\/v2\/wiki\/12755","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/krayer.de\/en\/wp-json\/wp\/v2\/wiki"}],"about":[{"href":"https:\/\/krayer.de\/en\/wp-json\/wp\/v2\/types\/wiki"}],"author":[{"embeddable":true,"href":"https:\/\/krayer.de\/en\/wp-json\/wp\/v2\/users\/4"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/krayer.de\/en\/wp-json\/wp\/v2\/media\/12756"}],"wp:attachment":[{"href":"https:\/\/krayer.de\/en\/wp-json\/wp\/v2\/media?parent=12755"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/krayer.de\/en\/wp-json\/wp\/v2\/categories?post=12755"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/krayer.de\/en\/wp-json\/wp\/v2\/tags?post=12755"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
