Is specialized software required for the CE marking of machinery?

Do you really need dedicated software for the CE marking of machinery?

No, actually you don't.

There is no general statutory requirement to use dedicated software for CE marking, risk assessment, or technical documentation.

Word and Excel can work perfectly well, particularly when managing few projects and having established routines.

However, drafting documentation is one thing. Maintaining cohesion across the entire workflow when multiple people, machines, and projects are involved is another.

How do you perform a risk assessment on machinery?

A risk assessment begins with determining the limits of the machinery and identifying hazards. Risks are then estimated and evaluated, and adequate protective measures must be implemented.

This process is typically based on ISO 12100, which sets out basic principles for risk assessment and risk reduction for machinery.

Must you use dedicated software for this, however?

No. A risk assessment in accordance with ISO 12100 can be documented in Excel, provided that the process is carried out correctly.

We have detailed the procedure further in our articles on machinery risk assessment in 5 steps and what ISO 12100 entails for machinery safety and risk assessment.

When do Word and Excel cease to suffice?

Consider a typical machinery project.

The design engineer maintains the risk assessment in Excel. The automation engineer is responsible for safety functions. The project manager chases mitigation actions via email, and the latest operating instructions reside somewhere on a local server.

Everyone performs their duties, yet obtaining a consolidated overview remains difficult.

Which protective measures are still pending? Which revision of the documentation is current? And who understands why a particular design solution was chosen?

This is precisely where the need for a centralised platform arises.

When knowledge walks out the door

Most of us have encountered the person with absolute control over the company's Excel templates.

They know which sheets need completing, which formulas are strictly untouchable, and why three different versions of the same risk assessment exist.

It functions adequately - until that person changes jobs, falls ill, or retires.

Suddenly, a successor is faced with deciphering years of bespoke adaptations, revisions, and document structures.

The files remain, but much of the underlying engineering rationale has been lost.

A structured system helps the organisation retain its methodologies, even through staff turnover.

It does not replace engineering experience or technical competence, but it significantly streamlines handover to the next engineer.

Standardised workflows, regardless of personnel

Another classic scenario involves internal, legacy templates developed ad-hoc.

One design engineer relies on their variant. A colleague has introduced individual improvements to theirs. Meanwhile, another department still relies on a deprecated version.

Naturally, each believes their iteration performs best.

The challenge arises when handing over a project or onboarding new engineering staff.

A unified platform enables the organisation to establish consistent workflows, reuse templates, and onboard new personnel more rapidly.

Crucially, however, a system must not be overly rigid.

In Noex, you can define custom project templates, legal requirement modules, checklists, and verification protocols, allowing you to establish a standardized framework tailored to your operations.

Standardised workflows, with the flexibility to adapt as required.

What is the true status of your projects?

For a design engineer, tracking unresolved hazards and pending mitigation measures is essential.

For a project manager or engineering lead, the concern is often broader:

What is our current project status?

When information is fragmented across disparate spreadsheets and email threads, finding the answer often triggers yet another meeting or manual report compilation.

Noex provides a consolidated overview of project statuses across the organisation. Managers can promptly identify areas requiring follow-up, while engineers track assigned actions directly via their personal dashboard.

There is a marked difference between having to request a status update and having real-time visibility.

What technical documentation is required to CE mark machinery?

Requirements depend on the machinery and the applicable regulatory frameworks.

Typically, the manufacturer must compile a risk assessment, technical design file, operating instructions, and an EU Declaration of Conformity. Design calculations, test reports, and verification records may also be required.

We have dedicated a separate article to the technical file requirements under the Machinery Directive.

Compiling documentation, however, is only one aspect of compliance.

A machinery project often encompasses safety requirement specifications (SRS), FAT and SAT protocols, checklists, and validation documentation.

Noex consolidates these elements within a single project environment, alongside hazard records, regulatory requirements, mitigation actions, and associated technical files.

There is one further critical element worth centralising:

Design decisions.

Consider how many technical safety decisions are agreed upon via Teams messages, email threads, or informal corridor discussions.

Three months later, someone must reconstruct why an interlocking guard was designed to specific dimensions.

Who accurately recalls the underlying reasoning then?

In Noex, notes, technical rationales, and discussions are logged directly against the project records.

Teams and email remain vital communication tools, but crucial compliance decisions should not be buried within them.

It must be evident not only what safety measures were implemented, but why.

Who monitors regulatory changes and harmonised standards?

Machinery safety is not a static regulatory environment.

Standards undergo continuous revision, new mandates emerge, and on 20 January 2027, the Machinery Regulation (EU) 2023/1230 becomes fully applicable.

Organizations using internal Word and Excel templates must manually track these regulatory shifts to ensure applicable standards are referenced.

A dedicated compliance platform centralises applicable legislation, harmonised standard references, and company templates in one location.

Noex incorporates libraries of legal requirements and standard references, along with the ability to build custom compliance structures.

Software does not, of course, supersede the engineering judgment required to evaluate how revised standards impact a specific machine design.

However, a structured framework greatly simplifies maintaining accurate, up-to-date compliance data.

What functional capabilities should CE marking software provide?

Requirements vary by organization, but key capabilities to evaluate include:

• Risk assessment according to ISO 12100 and conformity assessment against legal requirements.

• Collaborative project environments, action tracking, and multi-user workflows.

• Customisable and reusable templates, checklists, and inspection protocols.

• Operating instructions, Declarations of Conformity, and technical file compilation.

• Project dashboards, machinery registries, and audit trails.

• Support for safety-related control functions, SRS, and safety validation.

Not every manufacturer requires the complete functional scope.

The optimal software is not necessarily the one with the most features, but the one that best integrates with your engineering and compliance workflow.

What is the true operational cost of relying on Excel?

Given that Word and Excel are already licensed, why invest in dedicated tools?

It is a valid question.

Software licence fees, however, represent only a fraction of total compliance expenditure.

How many engineering hours are consumed searching for files, updating non-standardised templates, and following up on corrective actions? What is the resource cost of onboarding a new compliance engineer?

In a previous analysis, we calculated a model demonstrating that small administrative inefficiencies account for over 50 billable hours annually for a manufacturer managing 20 machinery projects.

While not an industry benchmark, it illustrates how rapidly micro-inefficiencies generate significant overhead.

Why did we develop Noex?

We engineered Noex out of the conviction that managing machinery safety and CE conformity assessment should be significantly more streamlined.

Collaborating closely with machinery safety specialists, engineering consultants, machine builders, and industrial manufacturers, we developed a cloud-based platform where risk assessments, regulatory requirements, safety actions, and technical documentation are integrated seamlessly.

The platform provides guided evaluation paths alongside workflows for open-format risk assessments and independent regulatory compliance audits.

For advanced machinery safety requirements, the platform supports machinery registries, assemblies of machinery, PLr and SIL determination, SRS authoring, calculation tools according to ISO 13855 and ISO 13857, and safety validation tracking.

Yet our objective with Noex is not to win a race for feature density.

The priority is ensuring that our tools genuinely reduce engineering friction.

Whether for the mechanical design engineer, the project manager, the CE compliance officer, or the technician closing out an allocated action.

How do you CE mark a machine?

CE marking involves far more than merely affixing the CE symbol.

The manufacturer must identify all applicable Directives and Regulations, execute a risk assessment, apply essential health and safety requirements (EHSR), verify conformity, and compile the technical construction file.

We have documented this end-to-end framework in our guide on CE marking of machinery – requirements, process, and technical documentation.

Which CE marking software should you implement?

Several solutions exist on the market, including Noex, Safexpert, and CEDOC.

The optimal choice depends on your specific technical requirements, team structure, and compliance project management model.

Within the Noex Academy, we have published a comparative guide designed to assist engineering teams in assessing compliance software platforms.

Read our guide: Machinery CE marking software – what does your organisation require?

Ultimately, do you truly need dedicated software?

No. It remains entirely possible to manage CE compliance within Word and Excel.

However, as project complexity and volume scale, compliance is no longer just about generating documentation.

It is about preserving technical institutional knowledge, reducing onboarding cycles, and enforcing systematic safety engineering methodologies across the enterprise.

It is about providing leadership with instant project visibility and ensuring critical safety rationales do not vanish into email archives.

Above all, it is about maintaining a single, traceable source of truth for your technical files.

Word and Excel can function. The critical question is whether they remain the most robust and defensible solution for your business.
