The Key Changes in NEN-EN 1090-2:2018

If you haven’t heard of this standard yet, the BS EN 1090 2:2018 is an international standard that applies throughout Europe. This standard contains the guidelines and technical requirements for the construction of steel (stainless steel) and aluminum.

The latest version of this standard will be introduced on the 1st of January 2019. This new version contains a number of important changes that will have an impact on the fabrication of steel structures. To give you a good insight, we have made a summary of the most important points of this new standard:

1. Removal of Default ‘EXC 2’

‘EXC 2’ has been removed as the requirements for the selection of execution class are now included in BS EN 1993-1-1: 2005 / A1: 2014, Annex C.

2. Thick Coating

New guidance on the determination of the loss of preload from thick coatings on contact surfaces in preloaded connections.

3. Introduction of ‘Weld Inspection Classes’

New guidance on the selection of ‘weld inspection classes’ has been included. This is where project specific % for NDT may be considered.

4. Thermal Cutting Activity

New guidance has been included for checking the capability of thermal cutting processes.

5. Reinforcing Steel

Rebar is now included.

6. 1090-4

For requirements regarding the thin gauge, these have been removed from this part of the series, and have been moved to 1090-4.

7. Normative Annex J

The ‘’Use of compressible washer-type direct tension indicators’’ has been removed.

Keep Meeting the Requirements

The standard is always under review by technical experts to bring it up-to-date and in line with current new industry practices. That’s why I recommend to always have a structured management system in place, in which it can be demonstrated that the requested quality is achieved.

To meet these requirements, Qooling has developed a welding (QMS) system in which the transition to new standards can be done smoothly, with no problems at all. Within the online solution you have all the necessary tools at your disposal. Keep track of your administration by digitizing internal documents. Easily demonstrate that requested quality is being achieved, and a lot of other handy features. Just visit the welding page or contact us and I will tell you all about it!

Introduction to NEN1090

Why NEN-EN1090?

The NEN-EN 1090 is part of the European series of product standards for the production of steel and aluminium constructions. Companies that work with steel and aluminium construction are required to meet this standard through the revised legislation on July 1, 2014. This means that all parts of steel and aluminium constructions must be provided with the CE-marking.

The FPC is a mandatory part of the EN 1090. This guarantees the quality of the manufacturer’s products. The main components of the FPC make it a kind of quality system according to ISO 9001, but more extensive with regard to technical requirements and less extensive in other areas, such as customer satisfaction. In addition, it´s a welding quality system based on EN-ISO 3834 (depending on the execution class). Finally, a welding coordinator should be appointed according to EN-ISO 14731. In order to continue to comply with this standard, it’s important that the administration is properly maintained.

The manufacturer declares with the CE marking that all structural requirements have been met. The basic principle is that a product must be accepted in all European countries if it complies with the standards. Member States can no longer impose their own requirements on products and companies. This should benefit every company that deals with construction.

How to continue to comply?

Proving compliance to the NEN-EN 1090 can be quite an intense job. The administration involved in showing traceability of welders and materials can already take up quite some time. On top of that, every weld needs to become traceable which in most cases leads to extensive Excel sheets and paper lying all over the workshop or production side. This will take up a lot of valuable production time because someone needs to fill in all the details, and needs to make sure it is archived properly and easily retrievable.

Qooling can help you to easily continue to meet the NEN 1090. We offer an online solution to keep the administration up to date and efficient so that unnecessary delay or failure costs are not incurred.

Through our software you can see at a glance what is happening within your company, and you have the complete traceability of all your welding.
