Pre-Evaluation: The Smart Step Towards a Smoother Certification Process

As certification requirements evolve and product timelines tighten, more manufacturers are turning to pre-evaluation to gain clarity, reduce risk, and ensure a smoother approval process.

At NMi, we’ve seen a clear shift: companies are no longer waiting until formal type approval to test. They’re preparing earlier — and seeing the benefits.

What Is Pre-Evaluation (Also Known as Pre-Testing)?

A pre-evaluation is a structured, early-stage test that helps manufacturers understand whether their product is on track to meet legal and technical requirements before official type approval begins.

Rather than waiting for the formal approval process to uncover issues, pre-evaluation allows you to identify potential gaps early — when they’re easier and less costly to address.

Why Pre-Evaluation Matters

Certification processes are complex, involving multiple standards, test conditions, and documentation requirements. Even small oversights can lead to project delays or repeated testing.

Pre-evaluation helps you:

• Detect issues early – uncover non-conformities before they affect timelines.
• Reduce redesigns – make technical adjustments while development is still flexible.
• Plan confidently – understand what’s needed for approval and prepare your documentation in advance.
• Streamline type approval – approach the official process with fewer surprises.

By testing under realistic conditions that reflect formal type approval standards, NMi helps you approach certification with clarity and confidence.
