Frequently asked questions

Which certifications does Assink & Schipholt hold?

We are certified to ISO 9001 for our quality management system, ISO 3834-2 for the quality requirements of fusion welding, and EN 1090-1 for the execution of steel and aluminium structures with CE marking.

What does ISO 3834-2 mean in practice?

That our welding is demonstrably under control: qualified welders, documented welding procedure specifications and traceable material. For every order it can be traced how a weld was made.

When do I need EN 1090-1?

For load-bearing steel and aluminium structures that must be supplied with CE marking, for example in infrastructure and construction. Because we are certified to EN 1090-1, we can supply such structures CE-compliant.

What documentation do you supply?

From incoming inspection to final inspection we record the steps: material certificates on arrival, qualified welding processes, dimensional inspection and release. State in your request which documentation you or your client require.

How do you check dimensions?

With measuring equipment and visual inspection, during and after production. For press braking we work to tolerances according to ISO 2768. State on the drawing which dimensions are critical and we will focus our inspection on them.
