Thermography, Drawings, Measurements: How Scope 10 Combines Three Layers of Fire-Risk Detection

A Scope 10 inspection is designed to answer one critical question: does your electrical installation contain fire risks that could be missed during day-to-day operation? For many businesses, that question becomes urgent only after an incident, a near miss, or an insurer request. By then, the cost of delay can be far greater than the cost of inspection.

What makes Scope 10 especially valuable is that it does not rely on a single way of checking an installation. Wassenaar Inspecties combines drawings and documentation review, visual inspection and electrical measurements, and thermographic examination to build a complete view of fire risk. Together, these three layers help reveal whether an installation is properly designed, correctly protected, and behaving safely under real conditions.

In this article, you will learn how each layer works, why the combination matters, and what to expect from a Scope 10 inspection.

What is a Scope 10 inspection?

A Scope 10 inspection is a thorough inspection of electrical equipment focused on minimizing fire risks. Wassenaar Inspecties assesses the installation using detailed drawings and documents to verify whether it complies with safety standards. The inspection also includes:

The goal is not only to identify visible defects, but also to create a complete picture of potential hazards within the installation.

Wassenaar Inspecties is officially SCIOS Scope 10 certified and focuses exclusively on inspections. Because the company does not carry out repair work itself, the inspection remains independent. If corrective work is needed, the customer's own installer can perform it.

Why Scope 10 uses three layers of fire-risk detection

Electrical fire risks are not always obvious. Some issues can be seen immediately. Others only appear when circuits are measured. Still others are only visible as heat patterns under operating conditions. That is why Scope 10 combines three complementary layers.

The three layers at a glance

Layer What it checks Why it matters
Drawings and documentation Design, identification, and alignment with the actual installation Confirms that the installation is documented correctly and can be assessed against requirements
Visual checks and measurements Condition, protection, continuity, resistance, impedance, and device operation Verifies whether the installation is safe and whether protective measures function properly
Thermography Heat development and possible overheating Helps detect abnormal temperature build-up that can indicate fire risk

Each layer contributes a different kind of evidence. Used together, they create a much more reliable assessment than any one method on its own.

Layer 1: Drawings and documentation provide the foundation

Before an inspector starts measuring or using thermal imaging, the installation needs context. That starts with drawings and documents.

During a Scope 10 visual inspection, Wassenaar Inspecties checks:

This first layer matters because documentation helps explain how the installation is intended to function. If drawings are missing, outdated, or inconsistent with the real situation, risks can be harder to interpret. A properly documented installation makes it easier to assess protective devices, circuit structure, and the relationship between different components.

In practical terms, drawings help answer questions such as:

For businesses with multiple modifications over time, this review is especially important. Changes in use, expansion, or undocumented adjustments can introduce uncertainty. Good documentation reduces that uncertainty.

Layer 2: Visual inspection and measurements test the installation itself

The second layer moves from paper to practice. Once the installation context is clear, the inspector checks the actual condition and performance of the system.

What the visual inspection covers

Wassenaar Inspecties checks for:

Visual inspection remains essential because many fire-related issues begin with physical deterioration, incorrect installation, poor identification, or damaged components. Even a well-documented installation can become unsafe over time if components age, loosen, or are exposed to unsuitable operating conditions.

What the measurements and tests verify

Measurements and tests during Scope 10 verify:

These tests are critical because electrical fire risk is often linked to faults that are not visible from the outside. A circuit may look acceptable while still having insulation problems, ineffective protection, or poor continuity.

For Scope 10 inspections, Wassenaar Inspecties uses the same tools as for Scope 8 inspections, including the FLUKE 1664 and a MEGGER MFT-X1. All instruments are calibrated on time.

Layer 3: Thermography reveals overheating that other methods may miss

The third layer is what sets Scope 10 apart most clearly: thermographic examination.

Thermography uses infrared imaging to detect temperature differences across electrical components. In a Scope 10 inspection, this method is used to identify possible overheating problems. Overheating can be a warning sign of developing faults, poor connections, overloaded components, or other abnormal conditions that raise fire risk.

Wassenaar Inspecties can include thermal imaging as part of its electrical inspections. For Scope 10, thermal imaging is carried out with a FLIR E60 camera or a HIKMICRO V2 camera.

Why thermography matters in fire-risk assessment

Heat is often one of the earliest visible indicators of electrical stress. A component may still function while operating at an unsafe temperature. That makes thermography valuable because it can reveal risk before failure becomes obvious.

Thermography is especially useful because it:

Thermal imaging works best when interpreted alongside the other inspection layers. A hotspot alone does not tell the whole story. But when heat patterns are considered together with documentation, condition checks, and electrical measurements, the findings become far more meaningful.

Why these three layers are stronger together

The strength of a Scope 10 inspection lies in the combination.

A drawing review can show how an installation is supposed to be arranged. Measurements can show whether protective and electrical characteristics are correct. Thermography can show whether components are developing unusual heat in practice. Each method answers a different question.

In simple terms:

  1. Drawings and documents show the intended setup.
  2. Visual checks and measurements show the technical condition and protection.
  3. Thermography shows how the installation behaves thermally.

This layered approach reduces blind spots. If one method suggests a concern, another can help confirm or clarify it. That is what makes Scope 10 such a practical approach for businesses that want a reliable fire-risk assessment.

What happens if the installation does not comply?

If an installation does not comply with the Scope 10 inspection, Wassenaar Inspecties issues a detailed report describing the identified defects and recommendations for improvements.

After corrections have been carried out, a re-inspection can be requested. Wassenaar Inspecties can also guide the implementation of the necessary adjustments.

After every inspection, an official report is prepared by the inspector.

If there is a serious finding, the customer is expected to resolve the issue with an external company and send the Herstelverklaring back so an inspector can assess whether the repairs were completed correctly.

What clients can expect before, during, and after a Scope 10 inspection

A clear process helps the inspection run smoothly.

Before the inspection

Before any inspection takes place, the client receives an Inspectierapport. This form must be filled in and signed so there is permission to work at the location and in the fusebox.

The estimated waiting time depends on the size of the installation. For locations with 1 or 2 fuseboxes, the estimated wait time is usually around 3 weeks.

During the inspection

During the inspection, it is advised that the client:

This helps the inspector work safely and efficiently.

After the inspection

Practical tips to get the most from a Scope 10 inspection

If you want your Scope 10 inspection to deliver the clearest possible outcome, these steps can help:

1. Keep drawings and documents up to date

Accurate documentation supports faster and more reliable assessment.

2. Make key installation areas accessible

Ensure the fusebox and related areas can be reached safely.

3. Treat heat findings seriously

Overheating is not something to ignore. Thermal anomalies often deserve prompt attention.

4. Act quickly on reported defects

A detailed report is most valuable when the recommended improvements are handled without delay.

Businesses that also want insight into workplace electrical safety may want to explore Scope 8 inspections. For solar panel installations, Scope 12 inspections are available as well. Wassenaar Inspecties also offers a combined Scope 8 and Scope 10 inspection for a broader view of electrical safety and fire risks.

Why businesses choose an independent inspection approach

Wassenaar Inspecties works independently and focuses exclusively on inspections. That matters because the assessment is separated from the repair work. The company states that it has no interest in rejecting an installation because it does not carry out repairs itself.

For clients, this can support confidence in the inspection outcome. The focus stays on identifying risks, documenting findings, and helping the customer move toward a safer installation.

Nationwide support and service

Wassenaar Inspecties can be quickly on-site anywhere in the Netherlands from its offices in:

The company is open Monday to Friday, 09:00–17:00 and is available to help with questions about its services and to guide clients through the inspection process.

Conclusion: Scope 10 works best because it sees risk from three angles

A strong Scope 10 inspection does more than spot obvious defects. It combines drawings, measurements, and thermography to assess fire risk from three essential angles: intended design, electrical performance, and thermal behavior.

That combination gives businesses a clearer basis for action. It helps identify defects, reveal overheating, and support safer operation of electrical installations over time.
