You come across DVGW certification all the time in the HVAC sector: on product packaging, in data sheets and in tender texts. But what does this certification actually mean? What are the requirements behind it and why is it really relevant for installers, planners and purchasers? This article provides clarity without a jungle of paragraphs. <\/p>\n\n
The DVGW, the German Technical and Scientific Association for Gas and Water, is a technical and scientific organization that develops regulations for gas and water supply in Germany. Its worksheets, testing principles and certification programs are regarded as recognized rules of technology. This means that anyone who plans and installs in accordance with DVGW requirements is on legally secure ground, as compliance with recognized codes of practice is a central duty of care in the installation trade in Germany. <\/p>\n\n
A fitting bearing the DVGW test mark has undergone an independent test procedure. Among other things, dimensional accuracy, material composition, pressure resistance, tightness and media compatibility are tested. Depending on the area of application, i.e. gas or water, different test principles and limit values apply. <\/p>\n\n
For malleable cast iron fittings from HS Fittings<\/a>, this means that certification in accordance with DVGW and also SVGW, the Swiss equivalent, proves that these fittings are approved for gas and drinking water installations in both countries. This is not a matter of course, as many manufacturers only have one of the two certifications. <\/p>\n Get more information now.<\/a><\/p><\/blockquote>\n\n In practice, DVGW certification provides protection on several levels. Firstly, under insurance law. In the event of damage caused by a leaking or faulty installation, the product quality used can become an issue. Certified products considerably strengthen the position of the installer. Secondly: In public tenders. Many clients explicitly demand DVGW-certified materials, especially for drinking water and gas installations in public buildings. Thirdly: During acceptance and testing. Experts and authorities accept certified products without any further obligation to provide evidence, whereas non-certified products can trigger inquiries. <\/p>\n\n In the drinking water sector, certification is becoming even more important as the European Drinking Water Directive further harmonizes and tightens the requirements for materials in contact with drinking water. Products that are already certified according to demanding DVGW test standards are a good starting point for this development. The relevant certificates and data sheets can be found in the HS Fittings download area<\/a>. <\/p>\n\n DVGW certification is not a bureaucratic accessory, but a tangible quality feature with legal and practical significance. For fabricators, planners and purchasers, it means less risk, more legal certainty and a stronger position in the event of acceptance tests and claims. HS Fittings offers DVGW and SVGW-certified fittings for gas and drinking water.
