Defined as measuring instruments in ISO 3310, test sieves are subject of national laws governing technical and legal metrology (e.g. Bundesgesetz \u00fcber das Messwesen MessG in Germany &amp; Switzerland, MEG in Austria) as well as quality assurance regulations such as ISO 9001. Additionally, when used for specialized applications, test sieves and their operation is subject to requirements and guidelines of various agencies (e.g. grain sieves are subject of regulations imposed by government intervention boards).<br><br>\n\nGenerally, under the legal terms of the majority of metrology laws, test sieves \u2013 when employed as measuring instruments in a legal sense \u2013 are to be \u201cinspected regularly,\u201d though the periods between inspections and the nature of the inspections themselves is left to the discretion of the operator. According to ISO 9001, an inspection is needed \u201cat regular intervals or prior to use\u201d whereas internal inspection by the operator or re-certification by an authorized entity are both permissible. For grain sieves, many regulations call for a mandatory annual re-certification (ref. German Federal Office for Agriculture and Food).<br><br><\/div><\/div><\/div><div id=\"panel-310-0-0-3\" class=\"widget_text so-panel widget widget_custom_html\" data-index=\"3\" ><div class=\"widget_text wow fadeIn panel-widget-style panel-widget-style-for-310-0-0-3\" data-wow-duration=\"2s\" data-wow-offset=\"100\" data-wow-iteration=\"1\" ><div class=\"textwidget custom-html-widget\"><a href=\"https:\/\/labsieves.com\/blau-metall\/wp-content\/uploads\/sites\/2\/2018\/02\/IMG_6481.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-339 alignleft\" src=\"https:\/\/labsieves.com\/blau-metall\/wp-content\/uploads\/sites\/2\/2018\/02\/IMG_6481-1024x597.jpg\" alt=\"\" width=\"420\" height=\"245\" srcset=\"https:\/\/labsieves.com\/blau-metall\/wp-content\/uploads\/sites\/2\/2018\/02\/IMG_6481-1024x597.jpg 1024w, https:\/\/labsieves.com\/blau-metall\/wp-content\/uploads\/sites\/2\/2018\/02\/IMG_6481-300x175.jpg 300w, https:\/\/labsieves.com\/blau-metall\/wp-content\/uploads\/sites\/2\/2018\/02\/IMG_6481-768x447.jpg 768w\" sizes=\"auto, (max-width: 420px) 100vw, 420px\" \/><\/a>To satisfy the requirements for regular internal inspection, operators of test sieves can employ calibrated Normsand or standardized material samples such as glass beads for sieve calibration which yields a cursory determination whether the sieve remains norm compliant and may be sufficient for most applications.
