When evaluating steel quality, the certificate is one of the most important elements. However, not all certificates are the same. The designations 2.1, 2.2, 3.1 and 3.2, defined by the EN 10204 standard<\/a>, indicate different levels of control, traceability and material reliability. Understanding these differences is essential to correctly assess a material and its quality level.<\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_single_image image=”49225″ style=”vc_box_shadow” onclick=”img_link_large” css=”.vc_custom_1776693186475{border-radius: 15px !important;}”][\/vc_column][\/vc_row][vc_row][vc_column el_class=”ba-box”][vc_custom_heading text=”\ud83e\udde0 Classification: two different approaches” font_container=”tag:h3|text_align:left” use_theme_fonts=”yes” css=””][vc_empty_space height=”16px”][vc_column_text css=””]\n

The EN 10204 standard<\/strong> defines inspection documents for metallic products.<\/p>\n

These are divided into two main categories:<\/p>\n

\ud83d\udd39 Non-specific inspection certificates
\n\ud83d\udd39 Specific inspection certificates<\/p>\n

\ud83d\udc49 The difference is substantial:
in the first case, they are general declarations<\/strong>, while in the second they are actual test results performed on the supplied material<\/strong>.<\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column el_class=”ba-box”][vc_custom_heading text=”\ud83d\udd0d Non-specific inspection certificates” use_theme_fonts=”yes” css=””][vc_column_text css=””]\n
