For companies working with technical installations, machinery, or building structures, NEN standards are a daily reality. They determine how products are designed, tested, and used. But who actually develops these standards, and how does that process work? In this article, we answer the most frequently asked questions about NEN standards, so you know exactly where you stand.
What are NEN standards and why are they important?
NEN standards are official technical agreements that specify how products, services, or processes must meet certain quality and safety requirements. They are developed by experts from industry, government, and academia, and serve as the recognized standard within a specific field in the Netherlands.
The importance of NEN standards is significant, especially in technical sectors. They provide a common language between manufacturers, clients, and users. When a product or installation meets the relevant NEN standard, it inspires confidence: it is demonstrably safe, reliable, and fit for its intended use.
NEN standards also play a role in laws and regulations. Governments and regulatory bodies regularly reference specific standards as minimum requirements. In sectors such as construction, electrical engineering, and the lifting industry, certain standards are even legally mandatory or part of permit requirements.
Who is responsible for developing NEN standards?
NEN standards are developed by NEN, the Royal Netherlands Standardization Institute, based in Delft. NEN is the officially recognized national standards organization of the Netherlands and coordinates the entire standardization process on behalf of the government and the business community.
NEN does not work alone. The institute organizes standards committees in which subject matter experts, manufacturers, users, research institutions, and government bodies collaborate. Anyone with relevant knowledge or a stake in a particular standard can participate in such a committee. This ensures that the final standard is broadly supported and reflects real-world practice.
NEN also represents the Netherlands in international standardization organizations such as ISO and CEN, meaning Dutch input contributes to global and European standards.
How does the standards development process work in the Netherlands?
Developing a NEN standard follows a structured process that begins with identifying the need for a new or revised standard. This signal can come from industry, government, or other stakeholders. A standards committee is then formed to carry out the substantive work.
The process broadly follows these steps:
- Initiative phase: A need for standardization is identified and submitted to NEN.
- Committee formation: NEN assembles a standards committee with relevant experts and stakeholders.
- Draft phase: The committee develops a draft standard based on technical knowledge and practical experience.
- Public comment round: The draft is published for public comment, allowing parties outside the committee to respond.
- Processing and adoption: Comments are reviewed and incorporated, after which the final standard is adopted and published.
- Periodic revision: Standards are regularly revised to keep pace with technological and societal developments.
This open and transparent process ensures that NEN standards are not developed unilaterally, but are the result of broad consensus.
What is the difference between NEN, EN, and ISO standards?
The difference lies in geographical scope and the organization that manages the standard. NEN standards are national standards that apply specifically to the Netherlands. EN standards are European standards, developed by CEN or CENELEC. ISO standards are international standards, developed by the International Organization for Standardization and applicable worldwide.
In practice, these levels are often combined. When a European EN standard is adopted in the Netherlands, it is designated NEN-EN. If an international ISO standard is also adopted at the European level and subsequently introduced in the Netherlands, it is referred to as a NEN-EN-ISO standard. This means the standard is valid at three levels: national, European, and international.
For technical sectors, this distinction is relevant when determining which standard applies to a product or installation, particularly when cross-border trade or projects in multiple countries are involved.
Which NEN standards apply to crane systems and lifting installations?
Several specific standards apply to crane systems and lifting installations, covering design, construction, safety, inspection, and use. The most relevant standards come from the NEN-EN series, as these are European harmonized standards that apply throughout Europe.
Some important standard series for crane systems include:
- NEN-EN 13001: Safety requirements for the design of crane structures.
- NEN-EN 15011: Specific standard for overhead cranes and gantry cranes.
- NEN-EN 14492: Standards for electric chain hoists and lifting equipment.
- NEN-EN 13135: Requirements for equipment used in crane systems, including mechanical and electrical components.
In addition to construction standards, there are also standards for periodic inspection and examination. In the Netherlands, lifting installations must be regularly inspected by an accredited inspection body. An accredited inspection company is authorized to carry out annual inspections, examinations, and subsequent maintenance, ensuring that crane systems always comply with the applicable NEN standards and legal requirements.
How can your company stay up to date on new NEN standards?
Staying informed about new and amended NEN standards requires an active approach. The most direct method is a subscription to the NEN Connect database, which gives you access to current standards and automatically notifies you of changes in the standard areas relevant to you.
There are also other practical ways to stay current:
- Participation in standards committees: Companies with specific expertise can actively participate in the standardization process through NEN, giving them early insight into developments.
- Industry associations: Many sectors have their own industry associations that keep members informed about relevant changes to standards.
- Suppliers and inspection bodies: Specialized parties such as crane manufacturers and accredited inspection bodies identify changes to standards that directly affect installations and processes.
- NEN newsletters: NEN regularly publishes updates on new and revised standards through their website and newsletters.
In 2026, keeping track of changes to standards is more important than ever, as the European standardization agenda is being actively updated in the areas of safety, sustainability, and digitalization. For companies working with crane systems and heavy lifting installations, it is advisable to partner with a company that actively monitors standards and translates them into practical implications for your installations.

Frequently Asked Questions
What happens if my installation does not comply with the applicable NEN standards?
If an installation does not comply with the applicable NEN standards, this can lead to a shutdown order from a regulatory authority, liability in the event of accidents, or the refusal of a permit. If in doubt, it is therefore advisable to contact an accredited inspection body directly for an inspection and advice on corrective measures.
How often are NEN standards for crane systems revised?
NEN standards are typically reviewed every five years and revised where necessary. For crane systems and lifting installations, it is important to check after each revision whether your installation still meets the current requirements, so you do not inadvertently continue operating under an outdated standard.
Can a small company also participate in developing NEN standards?
Yes, smaller companies can also participate in a standards committee through NEN, provided they have relevant knowledge or a stake in the standard in question. Participation is a great way to stay informed early about upcoming changes and to have a direct influence on standards that affect your sector.
Does a NEN-EN standard automatically apply in other EU countries as well?
Yes, a NEN-EN standard is based on a European EN standard that must be adopted by all EU member states. This means that an installation that complies with the NEN-EN standard in principle also meets the applicable requirements in other European countries, which considerably simplifies cross-border projects.
