In 2008, AFNOR Certification has developed the application of the <strong>NF VALIDATION mark<\/strong> to the sector of the <strong>microbiological analysis of water<\/strong>.<\/p>\n<p style=\"text-align: center\"><a class=\"btn-blue center\" href=\"#discover-certified-methods\">Access to the certified methods by germs on water analysis<\/a><\/p>\n<h2><strong>Two different forms of certification<\/strong><\/h2>\n<h3><em>Legionella<\/em> by PCR<\/h3>\n<p>The first form is specific to the <strong>detection\/quantification of <em>Legionella<\/em> and <em>Legionella pneumophila<\/em> by PCR<\/strong>. It is based on the determination of the intrinsic performance of the kit to be validated on the basis of the standard NF T90-471 and ISO\/TS 12869. These standards describe the requirements for<em> Legionella<\/em> PCR kits, in terms of context, performance and control. With the help of specialist experts in the field, AFNOR Certification has developed a protocol based entirely on these standards and adapted to the requirements of third party certification.<\/p>\n<h3>Other alternative methods for water analysis<\/h3>\n<p>The second form of certification focuses on the <strong>comparison of the method to be validated with the standardized reference method<\/strong>, thus adopting the same principle implemented in the validation of methods in the food industry. A general technical protocol, determining the criteria to be tested (selectivity, sensitivity, accuracy, linearity, repeatability, etc.) has been developed by AFNOR Certification with the help of his experts network. This protocol proposes experimental design and appropriate statistical processes.<\/p>\n<p>&nbsp;<\/p>\n<h2 id=\"discover-certified-methods\">Access to the certified methods by germs on water analysis<\/h2>\n<p>You will find below listed the certified analytical methods and holder companies.
