Frequently asked questions

Can I bring my own measuring instruments? 

During this training, we use various measurement tools. Do you want to bring your own measuring instrument? Then you may. For example, the well-known instruments by Flue, Gossen Metrawatt and Nieaf-Smitt. 

Is NEN 3140 Inspector compulsory? 

An entrepreneur is not obliged to inspect machines and devices in accordance with NEN 3140. But you do have to ensure a healthy and safe workplace for your employees. That’s in the Working Conditions Act. This includes safe work equipment. 

The Working Conditions Act refers to NEN 3140. So with the NEN 3140 Inspector, you are always in the right place as an employer in terms of insurance and legal matters! 

In addition, machines must comply with the standards of the European Machinery Directive. For example, every machine placed on the market or used within the European Union must meet the safety and health requirements of the Machinery Directive. This has been established by law. 

Of course, as an organization, you can hire an inspector. Nevertheless, it is often cheaper and more convenient to train employees to become NEN 3140 inspectors. Inspections are easier to plan and it saves costs. 


Would you like to organize a NEN 3140 inspector course at your location? No problem! Our trainer likes to come by. You take care of the coffee, we take care of the rest.
