The standard specifies performance levels (PL a to e) that quantify the reliability of safety functions. It includes systematic methods for risk assessment, architecture selection and validation. In membrane filtration systems, EN 13849-1-compliant safety technology ensures the protection of operators from mechanical, electrical and process-related hazards through certified safety components and circuits.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Standard concept<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">EN 13849-1 requires a structured risk assessment in accordance with ISO 12100, which results in the required performance level. The safety function is implemented using architecture categories (B, 1, 2, 3, 4) with defined fault detection and redundancy concepts. MTTFd (Mean Time To Dangerous Failure), diagnostic coverage (DC) and fault exclusion factors (CCF) are included in the calculation. Safety PLCs, safety relays or redundant circuits implement the logic. Validation is carried out through systematic tests and documentation in the safety report.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Areas of application<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">EN 13849-1 is mandatory for all machines in the European Economic Area and also applies to membrane filtration systems as part of the CE marking in accordance with the Machinery Directive 2006\/42\/EC. It protects personnel from moving parts such as pumps and agitators, prevents excess pressure and ensures safe access to maintenance areas. Performance level PLd or PLe are typical for safety-critical functions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Typical areas of application:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Emergency stop circuits with safe shutdown of all drives<\/li>\n\n\n\n<li>Access guarding to moving system parts (light curtains, safety gates)<\/li>\n\n\n\n<li>Pressure limitation to protect against the risk of bursting<\/li>\n\n\n\n<li>Safe speed monitoring for agitators<\/li>\n\n\n\n<li>Two-hand controls for maintenance releases<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Summary<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">EN 13849-1-compliant safety technology is a legal requirement for CE marking and the operation of machinery in the EU. It minimizes accident risks, reduces liability risks and fulfils operator obligations in accordance with the Ordinance on Industrial Safety and Health. For plant manufacturers, it means systematic safety design, market access and a competitive advantage through verifiable safety in membrane filtration plants.<\/p>","protected":false},"excerpt":{"rendered":"<p>Kurzdefinition Die Sicherheitstechnik nach EN 13849-1 definiert Anforderungen an die Gestaltung und Integration sicherheitsbezogener Teile von Steuerungen (SRP\/CS) in Maschinen und Anlagen.
