Diagnosis

The Problem We Solve

Compliance projects concluded visually, but without technical proof that the circuits achieve the performance level required by the standard. This creates a severe risk of a silent dangerous failure in the control system.

Methodology

Structured Analysis and Testing

Strict application of ISO 13849-1. We evaluate the architecture of the SRP/CS (Safety-Related Parts of the Control System), determine parameters such as MTTFd (Mean Time to Dangerous Failure) and DC (Diagnostic Coverage), and perform functional and fault-oriented tests in the field.
