It provides measurement deviations and measurement uncertainties as the basis for reliable measurement results. Requirements regarding competence, traceability, measurement uncertainty evaluation and documentation are laid down in DIN EN ISO\/IEC 17025 for calibration laboratories.<\/p>\n<p><strong>Practical relevance:<\/strong> Calibrated test equipment is an essential prerequisite for valid results in <a class=\"tc-inlink\" href=\"\/en\/materials-testing-analysis\/\">materials testing<\/a>, <a class=\"tc-inlink\" href=\"\/en\/home\/welding-brazing-soldering\/production-monitoring-welding-brazing-soldering-processes\/\">production monitoring<\/a> and quality assurance. Display deviation, repeatability and conformity with specified tolerances are assessed. Traceability is achieved via national standards, e.g. those of the PTB. Uncalibrated measuring instruments can lead to systematic misjudgements and liability risks.<\/p>\n<p><strong>Decision-making perspectives:<\/strong><\/p>\n<ul>\n<li><strong>Technical decision-makers:<\/strong> Ensuring correct test forces (e.g. in tensile or hardness testing) and process parameters.<\/li>\n<li><strong>Purchasing\/project management:<\/strong> Selecting accredited calibration service providers and defining risk-based intervals.<\/li>\n<li><strong>Science:<\/strong> Evaluating the measurement uncertainty and reproducibility of experimental data.<\/li>\n<li><strong>Insurance\/law:<\/strong> Demonstrating proper monitoring of test equipment in the context of product liability.<\/li>\n<\/ul>\n<p><strong>Typical testing or verification methods:<\/strong> Comparison calibration with force, pressure, torque or length standards, documentation of the traceability chain to national or international standards, issuing of a calibration certificate, where applicable with a conformity statement based on a defined decision rule.<\/p>\n<p><strong>FAQ:<\/strong><\/p>\n<ul>\n<li>Which mechanical measurands must be calibrated regularly?<\/li>\n<li>In particular force, pressure, torque and length measuring instruments in quality-relevant testing and production processes.<\/li>\n<\/ul>\n","protected":false},"author":0,"featured_media":0,"template":"","encyclopedia-tag":[],"class_list":["post-3155","encyclopedia","type-encyclopedia","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.technical-center.de\/en\/wp-json\/wp\/v2\/encyclopedia\/3155","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.technical-center.de\/en\/wp-json\/wp\/v2\/encyclopedia"}],"about":[{"href":"https:\/\/www.technical-center.de\/en\/wp-json\/wp\/v2\/types\/encyclopedia"}],"wp:attachment":[{"href":"https:\/\/www.technical-center.de\/en\/wp-json\/wp\/v2\/media?parent=3155"}],"wp:term":[{"taxonomy":"encyclopedia-tag","embeddable":true,"href":"https:\/\/www.technical-center.de\/en\/wp-json\/wp\/v2\/encyclopedia-tag?post=3155"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
