For the installation of safe low-voltage installations, NEN1010 is the standard and has a legal framework through its designation from the Buildings Decree.

More about this on the site of the national government building code online

NEN 1010-6 Part 6 of NEN 1010 contains the regulations and inspection requirements for performing the first inspection before commissioning the electrical installation. But in contrast, it is not mandatory according to the Buildings Decree.

Nevertheless, there are important reasons to have a NEN 1010 inspection carried out anyway:

With a NEN 1010 inspection and the accompanying report, you have proof that your Electrical installation has actually been installed according to the legal requirements.

As an employer, you are obliged to ensure the safety of your employees (ARBO legislation). This also applies to the new electrical installation. With the NEN 1010 report, you can demonstrate that this is the case.

When we inspect your new electrical installations in accordance with NEN 1010, it is fully visually checked and various measurements are taken. The data will be included in the inspection report you receive prior to delivery. This report will state whether or not the electrical installation meets the provisions of NEN 1010 and/or can be used safely.

When we inspect your existing electrical installations based on NEN 1010, agreements made with regard to the scope are recorded in an inspection agreement. According to the agreements made, the installation is visually inspected and measurements are taken, the findings are included in the inspection report. This report will state whether or not the electrical installation satisfies the provisions of NEN 1010 and/or can be used safely.



The NEN 3140 standard (operation of electrical installations) consists of 3 parts

  • Organisation and personnel
  • Instruction and instructions
  • Inspection and supervision

Organisation and personnel includes setting up a policy around the operational management of electrical installations and work equipment; setting up a structure of responsibilities and defining the activities.

Instruction and designation ensures that work on electrical installations is carried out only by properly trained and authorised persons.

Inspection and supervision consists of carrying out the inspection and supervision of the installation; part of this is drawing up an inspection plan for installations, machinery and work equipment.

Steegman Elektrotechniek has extensive experience to advise and assist you in implementing your business operations based on the NEN 3140. We are Scios (scope 8) certified for the inspections.



One in three fires is caused by a defect in the electrical installation which is why insurers actively encourage inspections of electrical installations.

As an example this particular site from Interpolis.

In practice, a NEN 3140 inspection was then prescribed, which standard is actually unsuitable for this purpose.

The NTA 8220 was developed by Techniek Nederland, iKeur and the Dutch Association of Insurers and is managed by the Dutch Standards Institute.

The Nederlands Technische Afspraak 8220 does not replace the NEN 3140, but is specifically aimed at signalling fire risks caused by the electrical installation. Signalling other risks caused by the electrical installation (such as safety, health, welfare or business continuity) are not part of this inspection methodology.

Steegman elektrotechniek is certified by Scios (scope 10) to carry out inspections based on the NTA 8220.

An inspection of electrical installations based on the NTA 8220 inspection is fully geared to the risk factors of your company and always consists of a visual check, measurements and tests and infrared recordings (thermography) of the distribution devices. The findings are incorporated into the inspection report and portal according to the scope 10 methodology.



Electrical installation safety does not stop at the wall socket or the connected equipment/machines.

From the ARBO law and certification bodies such as VCA but also insurance companies from their liability insurance, electrical machinery and equipment must be inspected periodically.

Steegman elektrotechniek assesses your electrical machinery and equipment according to the methodology of the NEN 3140. We have extensive experience in setting up administrative systems to register and manage work equipment, ranging from a registration list to fully automated systems where users are automatically informed by e-mail of the inspection status of the machines and equipment.



The NEN1010 literally states:

“In medically used rooms, the safety of patients eligible for treatment with medical electrical appliances must be ensured.”

“Safety can be achieved by ensuring the safety of the installation as well as safe operation and maintenance of the medical electrical appliances connected to the installation.”

Inspectors from Steegman Elektrotechniek have the necessary training, knowledge experience and equipment to assess your medically classified room(s) in the electrical field according to the applicable standards and regulations.



Faults and/or defects in electrical installations often manifest themselves in temperature increases of installation parts. If these symptoms are not recognised in time, they can eventually lead to malfunctions and/or fire.

Thermographic examination is a proven method for tracing potential defects at an early stage.

With this inspection method, it is possible to quickly detect defects such as poor electrical connections overload and asymmetry.

Thermography in itself is not a fully-fledged inspection method as a replacement for an inspection based on NEN 3140 and/or NEN 1010, but it is a fast and safe way to detect occurring faults in an electrical installation.

Thermographic inspections of electrical installations are performed by Steegman Elektrotechniek on the basis of NPR 8040-1.



Electricity and electrical appliances have become part and parcel of everyday life. Electricity is used day and night; at home, at work and in traffic for lighting, heating and appliances. The government requires numerous energy-saving measures, such as installing solar panels, LED lighting and frequency-controlled drives.

All these energy-saving devices pollute the power grid and negatively affect power quality (quality of voltage and current). At the same time, these devices are increasingly sensitive to the pollution they themselves cause. This has major consequences for the stability of the electrical power supply. Steegman Elektrotechniek has the knowledge expertise and state-of-the-art measuring equipment to monitor and provide insight into the condition of the installation.


Power Quality is a term used to describe the mutual interaction of voltages and currents in an electrical installation. For reliable operation of electrical components in an installation, the quality of the applied voltage and absorbed currents is extremely important.

A “healthy” voltage leads to lower maintenance costs, helps prevent breakdowns and saves electrical energy.

Poor Power Quality is the cause of many unexplained failures in an installation.

Depending on the type, size, scope and aart of the problems, it is determined at which points within the installation should be measured. This can involve one or several points. The relevant measurement data are processed in a report, in which the scope and possible cause are mentioned together with advice on possible adjustments.

Steegman Elektrotechniek carries out measurements in accordance with the NEN-EN 50160 standard. This is a Dutch standard, based on the European standard, in which the required voltage quality is determined.


A capacity analysis is used to determine whether the electrical installation can support a possible expansion.

Depending on the type, size and scope of the installation(s), it is determined at which points within the installation can be measured. This can involve one to several points. The relevant measurement data are incorporated into a report, which will state whether or not the electrical installation can be expanded, together with advice on any adjustments that can be made.



Precise information on the location of underground pipework is becoming increasingly important to protect employees, equipment and infrastructure during excavation work. It is wise to locate and mark pipes before starting work. Steegman Elektrotechniek can map exactly where cables run by means of cable detection.

Power cuts, cable breaks, short circuits, dormant faults in cables we can also detect for you, and determine the location of fault location.



An essential part of constructing a data network is measuring after the cabling has been laid. The purpose of this is to detect any faults in the cabling. After all, these can have a major impact on the overall performance of the network.

The results of the measurements, give a good picture of the reliability of your data network. This information from the measurements and analyses is processed per connection in a report
