EU Machinery Regulation 2027: What Documentation Teams Need to Know

As of January 2027, the Regulation (EU) 2023/1230 will replace the Machinery Directive 2006/42/EC, changing the way machinery manufacturers provide key product information. The Regulation goes beyond defining product-safety requirements: it creates concrete obligations for technical documentation, instructions for use, digital delivery, declarations, traceability, and information management. As the deadline for the new Regulation approaches, manufacturers and documentation teams must review and update their content to meet certification requirements and avoid delays in bringing products to market.

In this two-part series, we’ll break down what’s changing from the Machinery Directive to the new Regulation, what you need to know to get compliant, and concrete insights for technical writers to get started quickly.

What is the EU Machinery Regulation?

Machinery Regulation EU 2023/1230 is the European Union law that replaces the previous Machinery Directive 2006/42/EC. It outlines mandatory health, safety, and design requirements for machinery on the EU market regardless of manufacturing origin. This Regulation becomes fully applicable on January 20, 2027.

What Machinery Is Included in this Regulation?

The regulation scope covers various types of machinery as well as related products and partly completed machinery. Understanding how these groups are defined will help you understand which products need to meet compliance requirements.

The types of machinery covered include:

• Interchangeable equipment
• Impact machinery
• Safety components
• Lifting accessories
• Chains, ropes and webbing
• Removable mechanical transmission devices

Including the latest technological developments is a core tenet of the new Machinery Regulation. The scope now also includes:

• Functional safety software
• Autonomous systems and AI technologies
• Machinery that is updateable or interconnected

Key Changes in Machinery Regulation (EU) 2023/1230

With some clear definitions in mind, let’s now break down the biggest changes and additions to the new Machinery Regulation.

• Market regulation: The new regulation strengthens market surveillance with clear, strict controls for machinery. It defines roles and responsibilities to ensure compliance. The EU Declaration of Conformity and CE marking requirements apply consistently to all eligible machinery.
• Risk documentation: There are new requirements for what information to include in risk assessments and how that needs to be featured in the instructions for use.
• Cybersecurity: Cybersecurity is included in this regulation as part of its health and safety requirements. It sets compliance expectations to protect machinery from unauthorized digital access and requires manufacturers to consider cybersecurity throughout product design.
• Software and safety: There are new stipulations for software requirements related to safety functions. Teams need to be careful as these requirements change when software is provided separately from the machinery.
• Health and safety: The regulation includes updated health and safety requirements detailed in Annex 3 of the Regulation. This also now includes concrete requirements for autonomous mobile machines.
• Digital documentation: Manufacturers can now provide digital technical documentation by default with a few exceptions for paper instructions.
• High-risk classification: The list of machinery that is classified as “high risk” has been restructured and expanded.

New Requirements for Software, AI, and Data-Driven Machinery

The Regulation introduces new documentation requirements for machinery incorporating safety-related software and AI-based control systems. Manufacturers must include additional technical information and evidence in their compliance documentation to demonstrate that these systems meet applicable safety requirements. This includes details for the system, data usage, development, testing, and validation processes.

There are also new health and safety requirements for software products to conform to, including cybersecurity considerations. Companies will need to provide risk assessments and product design documentation to prove conformity.

The technical file must also include a document describing the relationships between physical machinery and software systems.

Technical Documentation vs. Instructions for Use: What's the Difference?

The Machinery Regulation establishes requirements for both technical documentation and instructions for use. Although they contain some overlapping information, they serve different purposes and audiences.

Instructions for use: Instructions for use are intended for the people installing, operating, maintaining, and, where applicable, dismantling machinery. They must provide the information users need to operate equipment safely.

These instructions are centrally relevant to technical writers as writing, structuring, translating, and maintaining the instructions falls under your scope. Regulation section 1.7.4 details the mandatory content, including manufacturer identification, intended use, foreseeable misuse warnings, installation, operation, maintenance, and more. The instructions must be understandable to their intended users and available in the language or languages required by the Member State where the machinery is placed on the market or put into service.

Technical documentation: The technical documentation is the manufacturer's evidence that the machinery was designed and built in line with the applicable requirements. It supports conformity assessment and demonstrates compliance to market surveillance authorities when requested.

This is partially relevant to technical writers. In most organizations, engineers and compliance teams will own the risk assessment, calculations, technical drawings, and test reports. As writers, you will add a copy of the instructions of use and any translations or summaries required by authorities. Documentation teams will also handle documentation management workflows including implementing document control, consistency checks between residual risks and instructions, versioning, and content retention processes.

What Goes in the Technical File

Every machine needs a technical file that supports the CE marking. It contains the technical documentation (the evidence of conformity) and a copy of the instructions for use (what users need to operate the machinery safely).

Sometimes both the technical documentation and instructions for use require the same type of information, but the audience or depth of information required differs.

What Should Technical Writers Focus on When Preparing New Regulatory Content?

The Regulation will require technical writers to reevaluate how they create digital documentation, explain predictable misuse of machinery, tailor content for different user groups, and manage translation workflows. Here’s a detailed look at these regulatory changes and how they will affect documentation team processes, strategies, and systems.

Prioritize Digital-first Documentation

You can now supply all instructions digitally, with exceptions. Manufacturers must provide paper instructions free of charge within one month of a user's request, and machinery that non-professional users may operate must come with paper instructions.

Providing documentation online means technical documentation teams will face new questions and considerations.

What this means for technical writers:

Document for Foreseeable Misuse

The instructions must address not only a product’s intended use but also any reasonably foreseeable misuse. For technical writers, this means documentation must be informed by the manufacturer’s risk assessment and not just the ideal operating scenario.

What this means for technical writers:

• Traceability: Map the content between items in the residual risk assessment and the instructions section that address each risk. Any residual risks not addressed in the instructions for use represent a compliance gap. This may also require closer collaboration with engineers to understand how products can be misused to create clear warnings in documentation.
• Translation: Misuse warnings are some of the most high-risk content to mistranslate. Teams must apply strict linguistic reviews for safety-critical text and ensure it is available in the languages your users need.

Write for the Actual User

The instructions for use must be comprehensible to non-professional product operators. Writers must consider operators’ general level of knowledge and adjust the terminology, information architecture, warning, illustrations, and instructions accordingly.

What this means for technical writers:

• User definition: Make sure your whole technical writing team is clear on who the users are before starting. What kind of training do your foreseeable users have? What can you assume they already know? This assessment will feed into your content strategy.
• Safety instructions: Warnings for non-professionals need plain language, clear consequences, and visual support. Don’t use jargon that may impede safety.
• Illustrations: Any graphics or illustrations must be tested with the machinery. The visuals also need to be unambiguous across cultures and languages, with translations for any text accompanying the visual.
• Information architecture: Content for operators versus specialized maintenance technicians must be clearly distinguished, so each user receives the information they need, nothing more and nothing less. Modular content, metadata, and authenticated user groups support this.

Review Translation and Localization Workflows

Instructions and safety information must be available in a language that is easily understood by users. This is determined by the Member State where the machinery is located. While this principle already exists in the Machinery Directive, there are new requirements. First, the Regulation has stricter requirements for instruction updates, which impacts translations. It also extends translation requirements to instructions for embedded software, display messages, human-machine interfaces, and QR code portals.

What this means for technical writers:

• Market language mapping: Identify the languages required for your instructions based on the Member States where you operate and their language rules.
• Originals vs. translations: Clearly define which version is the original instructions for reference and put quality assurance processes in place to validate each translation against the reference material.
• Terminology and content reuse: When you use modular, reusable content and consistent terminology, this helps reduce translation costs and risks. Put in place the workflows and tools needed to manage translations, terminology consistency, localization, and content reuse.
• Update synchronization: When machinery changes alter the instructions, you need to update all impacted language versions. This needs to happen before the machinery update is live for users, which may require updated release schedules and coordination between product and documentation teams.
• Digital delivery: Make sure users can easily access documentation in their preferred language. For example, teams could manage this through documentation portal user settings, a language selector, or QR codes based on each market location.

Build Change Control for Software and Product Updates

Digital instructions make updates look easy, but they require disciplined change control, and each new feature, software version, or interface redesign can create new opportunities for misuse.

What this means for technical writers:

• Define change workflow: Decide what triggers a documentation update, especially for firmware and configuration changes.
• Clarify responsibility: Assign who owns, reviews, and approves each change, and how users are notified.
• Implement safety checks: Re-run the risk assessment review, followed by an instruction review, for every change that could affect residual risks.

Conclusion

The new Machinery Regulation underscores the importance of documentation and instructions for use, making content an integral part of proving product conformity. Many of the implications for technical writers are already in line with current documentation best practices. However, there are also several new requirements that may impact workflows around safety instructions, translation management, product updates, and version control.

Stay tuned for part two to dive into how these requirements are shifting documentation workflows with a clear plan to achieve compliance.
