How are NEN standards established and revised?

NEN standards play a central role in Dutch industry. They form the technical language that companies, governments, and manufacturers share to ensure safety, quality, and interoperability. For companies working with complex technical systems, such as crane installations, NEN standards are not a side issue but a fundamental part of responsible business practice. In this article, we explain how NEN standards are developed, how they are revised, and how your organization can actively contribute to that process.

What are NEN standards and why do they matter?

NEN standards are voluntary technical agreements that describe how products, services, or processes should be designed, tested, or carried out. They are developed by the Royal Netherlands Standardization Institute (NEN) and provide a common basis for quality, safety, and interchangeability within a sector or industry.

The importance of NEN standards lies in the practical certainty they offer. A standard translates complex technical and safety requirements into concrete, actionable guidelines. For industrial sectors such as the crane industry, standards are indispensable: they define, among other things, the structural requirements for lifting installations, maximum load capacities, and mandatory inspection procedures. Without shared standards, each company would have to determine for itself what is safe enough, leading to inconsistency and risk.

Although compliance with NEN standards is in principle voluntary, they are in practice frequently made mandatory through legislation, procurement requirements, or contractual agreements. This makes them effectively binding for companies operating in regulated sectors.

Who decides which NEN standards are developed?

NEN standards are not determined by a single party. The initiative for a new standard can come from companies, industry associations, government bodies, or knowledge institutions that identify a need for harmonized technical agreements. NEN acts as an independent organization that facilitates and oversees this process.

Once a need has been established, a standards committee is formed. This committee consists of representatives from all relevant stakeholders: manufacturers, users, regulators, research institutions, and sometimes consumer organizations. The principle is that no single party holds a dominant position, so that the final standard reflects a broadly supported consensus.

At the European and international level, NEN collaborates with CEN (European standardization) and ISO (international standardization). Decisions about which standards are developed are made in international committees, with NEN representing the Dutch contribution.

How does the process of establishing NEN standards work?

Establishing a NEN standard follows a structured process that begins with a formal proposal and ends with publication following broad consensus. The timeline ranges from several months to several years, depending on the complexity of the subject and the number of parties involved.

The process broadly follows these steps:

Initiation phase: A party submits a request to NEN to develop or revise a standard.
Committee formation: NEN assembles a standards committee with representatives from all relevant stakeholders.
Drafting: The committee prepares a draft text based on existing knowledge, practical experience, and technical insights.
Public consultation: The draft is published publicly so that anyone can submit comments. This is a crucial step for building broad support.
Processing comments: The committee reviews all submitted responses and incorporates relevant feedback into the final text.
Adoption and publication: After approval by the committee and NEN, the standard is published and officially comes into effect.

This process ensures that an adopted NEN standard is not the opinion of a single party, but the result of a carefully balanced technical and societal debate.

How are existing NEN standards revised or withdrawn?

Existing NEN standards are periodically reviewed, typically every five years, to determine whether they remain current. If technological developments, new insights, or changes in legislation render the content outdated, a revision process is initiated. A standard may be updated, replaced, or withdrawn.

A revision largely follows the same process as drafting a new standard: a committee analyzes the existing text, identifies what needs to change, and works through the steps from draft to public consultation and adoption once again. When a European or international standard is revised, this automatically affects the corresponding NEN standard.

Withdrawal occurs when a standard has become entirely obsolete, when a new standard replaces the old one, or when there is insufficient support to keep the standard up to date. After withdrawal, the standard may no longer be used as a reference in contracts or inspections, unless the parties involved explicitly choose to do so.

What is the difference between NEN, NEN-EN, and NEN-ISO standards?

The prefix of a standard indicates its origin and scope. A NEN standard is a purely Dutch standard, developed for and by the Dutch market. A NEN-EN standard is a European standard (EN) that has been adopted and translated by NEN for use in the Netherlands. A NEN-ISO standard is an international ISO standard that has been adopted in the same way.

In practice, NEN-EN standards are the most common in industrial sectors, as European harmonization continues to advance. When a European standard is published, all EU member states are required to adopt it and withdraw any conflicting national standards. This creates a level playing field within the European market.

For the crane industry, for example, NEN-EN standards from the EN 13001 series and EN 15011 are relevant, as these establish the structural and safety requirements for lifting cranes at the European level. Companies operating in multiple countries benefit from this harmonization because the same standard applies in all member states.

How can companies contribute to NEN standardization?

Companies can participate in the NEN standardization process in several ways. The most direct way is to take part in a standards committee, where company representatives contribute to writing new standards or revisions. In addition, any company or individual can submit comments during the public consultation round for a draft standard.

Participating in standards committees offers strategic advantages: companies that actively contribute understand new standards earlier and can adapt their products or processes in a timely manner. Moreover, you help shape standards that reflect the realities of your sector, rather than having to follow rules set by others.

For companies that want to contribute but lack the capacity for full committee participation, NEN also offers the option to act as an informal commentator through the public consultation. Industry associations often play a coordinating role here by consolidating input from multiple companies.

Frequently Asked Questions

Are NEN standards legally required for our company?

NEN standards are in principle voluntary, but in practice they often become binding through legislation, procurement requirements, or contractual obligations. Particularly in regulated sectors such as the crane industry, compliance is effectively unavoidable.

How do I know which NEN standards apply to my crane systems?

You can search by keyword or sector on the NEN website to find relevant standards. For crane systems, the NEN-EN 13001 series and EN 15011 are among the most important; a specialized party such as BKRS can also provide you with concrete advice on this.

What happens if I work with a withdrawn NEN standard?

After withdrawal, a standard may no longer be used as an official reference in contracts or inspections. If you do so anyway, you risk failing to meet current safety and quality requirements, which can have legal and insurance-related consequences.

How can I as a small company still influence NEN standardization?

Through the public consultation round, any company — regardless of size — can submit comments on draft standards. Industry associations often consolidate input from multiple smaller companies, ensuring that your practical experience is still taken into account in the standardization process.
