Why Risk Assessments Are Critical to Product Certification

28 Oct 2026

One of the Most Valuable Engineering Tools Available During Product Development

When manufacturers prepare a product for safety certification, the focus is often on testing. Engineering teams typically concentrate on electrical testing, environmental testing, construction reviews, and demonstrating compliance with the applicable standards.

However, in many certification projects, delays are not caused by failed tests. Instead, they often originate much earlier in the process during the risk assessment.

From the perspective of certification engineers, risk assessment is one of the first places where potential issues appear. If it is incomplete, inconsistent, or performed too late in the design cycle, it can trigger additional questions, design changes, or extended review cycles.

Understanding how risk assessments are used during certification can help manufacturers avoid these issues and move through the evaluation process more efficiently.

Risk Assessment: More Than a Hazard List

A risk assessment is far more than a checklist of hazards. For certification engineers, it is a document that explains the engineering logic behind the product’s safety design. In simple terms, the risk assessment should clearly answer an important question:

• What happens if something goes wrong?

During certification reviews, engineers typically look for answers to questions such as:

• What hazards exist during normal operation?
• What failures could create unsafe conditions?
• How might users interact with the product in unintended ways?
• What design measures prevent or reduce those hazards?

When the reasoning behind safety decisions is clearly documented, certification reviews tend to move quickly. When assumptions or justifications are unclear, additional questions and analysis are usually required.

The Timing Problem

One of the most common challenges encountered during certification is when the risk assessment is performed.

In many development programs, risk assessment is created just before certification submission. At that stage, the design is largely complete, and prototypes have already been built. As a result, the risk assessment becomes more of a documentation exercise than a tool used to guide the design process.

If hazards are identified at this late stage, addressing them may require design changes that affect cost, schedules, or product performance.

The most effective approach is to treat risk assessment as an ongoing engineering activity that evolves alongside the product design.

Looking Beyond Normal Operation

Another common issue arises when risk assessments only consider the product during normal operation. In reality, many hazards can be introduced to the design during other stages of the product lifecycle, including:

• Installation
• Maintenance and servicing
• Troubleshooting
• Transportation
• Foreseeable misuse

For example, equipment may operate safely when protective guards are installed. However, maintenance procedures may require those guards to be removed. During these activities, operators may be exposed to hazards that are not present during normal operation. 

A comprehensive risk assessment considers the entire lifecycle of the product, from installation and operation to servicing and end-of-life handling.

International safety standards emphasize the importance of lifecycle-based hazard evaluation. For example, ISO 12100, the foundational standard for machinery risk assessment and risk reduction, requires manufacturers to consider hazards not only during normal operation but also during installation, maintenance, cleaning, troubleshooting, and foreseeable misuse.

Why Clear Documentation Matters

Even when a product design is fundamentally safe, incomplete documentation can create unnecessary delays during certification reviews. Certification engineers must be able to follow the logic behind the safety design. If key assumptions, hazard evaluations, or mitigation strategies are not clearly documented, additional clarification may be required.

A well-prepared risk assessment typically includes:

• Clear definitions of product limits and intended use
• Hazard identification across the product lifecycle
• Transparent explanation of risk evaluation methods
• Justification for selected mitigation strategies
• Documentation of residual risks and quantifying the values that are acceptable

When this information is organized clearly, certification reviews become significantly more efficient.

Risk Assessment as a Competitive Advantage

Risk assessment is sometimes viewed as a regulatory requirement that must be completed for certification. In reality, it is one of the most valuable engineering tools available during product development.

When applied early and used effectively, risk assessments help engineering teams:

• Identify hazards earlier in the design process
• Reduce the likelihood of redesign during certification
• Improve communication between engineering and certification teams
• Create a more predictable certification timeline

The result is not only a safer product, but also a more efficient certification process.

How Intertek Supports Manufacturers

Navigating product safety certification can be complex. Intertek supports manufacturers throughout the product development lifecycle by helping teams identify hazards early, evaluate safety functions and their required reliability, and prepare certification-ready documentation.

Our Assurance team can assist with the risk assessment process, and we offer training to help manufacturers build internal expertise in conducting product safety risk assessments.
