These complex standards prescribe the requirements that our processes and products must comply with. We would be glad to explain what these certifications are comprised of and can tell you which standards apply to the product that you would like to have built.
If you have any quostions about the ISO 9001:2015, ISO 14001:2015, ISO 2834-2, NEN-EN 1090-1, MPT-2 and the VTW-2 standards, please feel free to contact us directly.
ISO 9001:2015
ISO 9001 is the best-known international quality management standard that is applied by more than a half a million organisations in 150 countries.
With an ISO 9001 certification, De Vries Welding meets international requirements in the area of quality management.
This certificate gives you the guarantee that we maintain high-quality standards. The emphasis of this management system is on process management, monitoring, constantly improving, realising objectives and an active managerial role. In short: an emphasis on managing the results.

ISO 3834-2
The ISO 3834 is a quality standard that concerns the entire welding organisation. This certification is proof that De Vries Welding BV has safeguarded all the quality requirements that concern the field of welding activities.
For organisations that manufacture (parts of) products, it is customary that these are ISO 9001 certified. The ISO 9001 certification does not, however, provide any clear information about the welding, except that it is a “unique process”.
In order to create a quality management system for welding, a partnership between the International Standardization Organisation (ISO) and the European Commission of Normalisation (CEN) has developed a special system of standards. This system of standards is better known as the ISO 3834-2, and is prescribed by buyers of welding structures and welding products in order to safeguard the quality of the welding activities.
The NEN-EN-ISO 3834 certification is an internationally recognised quality management system for welding activities. In this standard, all the work activities in the field of welding are described.
The ISO 3834-2 certification is virtually always required by all clients in the on & off-shore, rail infrastructure, defence and petro-chemical industries. In other sectors too, this internationally-recognised quality management system for welding activities is being valued more and more. Download the certificate.
NEN-EN 1090-1
As of 1 July 2014, all manufacturers of construction parts with welding qualities must carry CE markings on their products. A CE marking is a declaration of conformity by us, the manufacturer of steel and/or aluminium constructional components
With a CE-marketing according to NEN-EN 1090, we declarw to comply with all given constructional requirements as is indicated in specifications, constructional calculations and drawings. Download the certificate.
MPT-2
This procedure is intended for the carrying out magnetic research by De Vries Welding B.V. The magnetic research takes place on ferromagnetic materials with a hand yoke electromagnet.
The implementation of the research is based on:
EN 17638 Magnetic welding research
EN 23278 Acceptability levels
The procedure is carried out by De Vries Welding B.V. and can be applied to projects that fall under the responsibility of De Vries Welding B.V. Download the certificate.
VTW-2
This procedure is intended for the carrying out visual inspection by De Vries Welding B.V. The visual inspection takes place prior to, during or after the welding of materials.
The execution of this inspection is based on:
EN ISO 17637:2011 Non-destructive inspection of welding – Visual inspection of fusions welds
EN ISO 5817-C: 2014 Welding – fusion welds in steel, nickel, titanium and their alloys.
The procedure is carried out by De Vries Welding B.V. and can be applied to projects that fall under the responsibility of De Vries Welding B.V. Download the certificate.
