It takes into account mechanical, thermal, chemical and tribological loads. The objective is to demonstrate compliance with technical and normative requirements.<\/p>\n<p><strong>Practical relevance:<\/strong> The assessment evaluates load-bearing capacity, deformation behaviour, leak-tightness, <a class=\"tc-inlink\" href=\"\/en\/corrosion-consulting-and-testing\/\">corrosion<\/a> resistance and fatigue strength. It may be based on standards, technical specifications or codes such as the Eurocodes, API standards or the Pressure Equipment Directive 2014\/68\/EU.
