FAQ

Online courses are ideal for experienced technicians who want to refresh their knowledge or renew an expired certificate. For beginners, a classroom-based course is often better. Both options are available at Euronorm Advies.

Euronorm Advies can set up a customised course for NEN 3840, NEN 3140 or ATEX – including company-specific photos, videos, procedures and a custom test with certificate. The costs consist of a preparation fee and a rate per participant.

A workbench does not fall under any CE directive. When used in industry, the Work Equipment directive must be taken into account.

When fundamentally changing the properties of products, such as increasing the WLL, the person making this change must also issue a new CE declaration.

The company should have supplied the machine with CE marking and is clearly in violation. Contact the manufacturer.

The Machinery Directive states that every machine must at least bear the name and address of the manufacturer, CE marking, series or type designation, serial number and year of manufacture.

The CE marking must be placed on the product — not just in the user manual.

Not all products fall under CE. The CE marking may only be affixed to a product if it falls under one or more directives.

This four-digit code appears after the CE logo if the manufacturer is obliged to involve a Notified Body (NoBo).

The government has multiple ministries that enforce in their respective areas. Control often works with random checks.

Oxygen trolleys do not fall under any CE directive and are therefore not provided with a CE marking.

Combining certified individual components does not mean that the combination is also safe. The designer of the assembly must check whether the components work together.

The CE marking must be affixed by the company that places the product on the market or first puts it into service.

If an extractor fan is placed on the European market as a stand-alone functional machine, you are obliged to provide it with a CE marking.

A vacuum lifter falls under the definition of lifting equipment and must be CE marked.

Disco lighting falls under the Low Voltage Directive and, if it contains electronics, also under the EMC Directive and the RoHS Directive.

There is no European directive that requires a sleeping pillow to be CE marked. So the answer is: no.

For machines manufactured before 1995, it must be investigated whether safety fences are mandatory.

Yes. Combining components creates a new machine. The assembler is responsible for the CE marking of the whole.

There is no formal training course for Notified Body. The government appoints you as a NOBO.

The designation 'Made in Holland' is subject to specific rules regarding the origin of the product.

A comprehensive overview of frequently asked questions about CE marking: from directives and declarations to practical applications and enforcement.

Machinery Directive 2006/42/EC is replaced by Regulation (EU) 2023/1230. From 20 January 2027, the new regulation applies to all machinery placed on the EU market.

No, machines placed on the market before 20 January 2027 do not need to be recertified.

A directive must be transposed into national law by Member States; a regulation applies directly in all EU countries without transposition.

The Machinery Regulation sets stricter requirements for cybersecurity, AI applications in machinery and digital instruction manuals.

If a product is intended for the diagnosis, prevention, monitoring or treatment of a disease or condition in humans, it falls under the MDR (EU) 2017/745 and CE marking is mandatory.

The MDR (EU) 2017/745 has replaced the old Medical Device Directive (MDD 93/42/EEC). The MDR sets stricter requirements for clinical evidence and post-market surveillance.

The MDR has four risk classes: Class I (lowest risk), Class IIa, Class IIb and Class III (highest risk).

According to the Working Conditions Decree, Article 7.4-a, anyone with sufficient knowledge may perform the periodic inspection – including in-house.

NEN 3140 sets minimum requirements. Some VCA-certifying bodies demand more, but cannot legally enforce it.

Whether household appliances in a business environment need to be inspected depends on the risk analysis.

For fully insulated appliances (Class II), you cannot measure the protective conductor. Check the type plate for the double insulation symbol.

Perform a visual inspection and measure the protective conductor up to the protective contacts. Check if the RCD is type A with a tripping current of maximum 30 mA.

In Germany, inspection is mandatory according to DIN VDE 0701/0702 instead of NEN 3140.

No, training is not legally mandatory. However, the government requires that you demonstrably have the knowledge and resources to carry out inspections properly.

If you do not perform installation work but do enter areas with electrical risk, you must be designated as a Sufficiently Instructed Person (VOP) in accordance with EN 50110-1 & NEN 3140.

Anyone with sufficient knowledge and resources may inspect work equipment (Working Conditions Decree, Article 7.4a).

The Installation Manager (IV) is responsible, in accordance with NEN 3140, for maintaining the safety of electrical installations and work equipment.

No. A Skilled Person (VP) is designated for low-voltage installations. For work in high-voltage areas, the VP NEN 3140 is not authorised.

EN 50110-1 is the European standard for inspection of electrical installations. NEN 3140 is a Dutch supplement that specifically describes the inspection of electrical appliances.

No, calibration of measuring instruments is not legally mandatory.

NEN 3840 is a Dutch standard based on EN 50110-1. The ENSR are company or grid operator-specific safety regulations for high-voltage installations, with more specific requirements regarding work procedures, authorisations, and permit-to-work systems.

NEN 3140 concerns low-voltage installations (up to 1000 V AC / 1500 V DC); NEN 3840 concerns high and medium voltage. The standards differ in scope, procedures, designations, and the complexity of work permits.

The IV is responsible for the safe condition and management of the high-voltage installation, compliance with safety procedures, and the instructions of the WV, VP, and VOP.

If you are designated as an Installation Manager (IV) in accordance with NEN 3840, you become responsible for the safe condition of the installation, work permits, designations, and procedures.

The VOP may perform limited tasks near high-voltage installations, such as simple operating procedures, visual inspections, cleaning or painting – always under supervision and after instruction.

NEN 3840 recognises continuous supervision and periodic supervision (once every 4 hours). The ENSR distinguishes between immediate supervision and personal supervision.

No, not everyone. According to NEN 3840, for a touch-safe installation, one person with at least a VOP designation may enter the area.

Online courses are ideal for experienced technicians who want to refresh their knowledge or renew an expired certificate. For beginners, a classroom course is often better.

For an installation with 8 bar air for pipes, you fall outside the scope of the PED.

During a PED audit, it may emerge that the description of the chosen solution is missing or that evidence is not available.

Existing installations that were not subject to inspection before the PED do not become subject to inspection by the PED.

Vehicles and their trailers do not fall under the PED.

Medical equipment that falls at most into PED category 1 and under the Medical Devices Decree is exempted from the PED.
