ISO 13849-4 Functional Safety of Electrical Control Systems
The ISO 13849 series addresses functional safety in automation systems, particularly focusing on the design and analysis of electrical control systems. This standard is crucial for ensuring that equipment operates safely within predefined performance levels under all expected conditions.
ISO 13849-4 specifically deals with the determination of protection layers to achieve a specified level of safety integrity. Protection layers include hardware, software, and organizational measures designed to prevent hazardous events from occurring or escalating to an unsafe state. The standard provides guidelines for assessing these layers through risk analysis methods such as Fault Tree Analysis (FTA) and Event Sequence Diagrams (ESDs).
The process involves defining safety objectives, identifying potential hazards, analyzing risks, and implementing appropriate protection measures. It ensures that the control system can handle faults without compromising safety. For HVAC equipment testing, this translates to verifying that electrical control systems meet stringent safety requirements.
At Eurolab, we specialize in providing comprehensive ISO 13849-4 compliance services for HVAC equipment manufacturers. Our team of experts ensures that every aspect of the testing process adheres strictly to the latest version of the standard, ensuring robust and reliable results.
| Step | Description |
|---|---|
| Define Safety Objectives | Determine the required safety integrity level based on risk assessment. |
| Identify Hazards | Analyze possible failure modes of electrical control systems. |
| Risk Assessment | Evaluate the likelihood and consequences of identified hazards. |
| Design Protection Layers | Create hardware, software, and organizational measures to mitigate risks. |
| Validation | Verify that the protection layers meet specified performance criteria. |
Applied Standards
In addition to ISO 13849-4, we also adhere to other relevant international standards such as IEC 61508 and EN 954. These standards provide a framework for the design, development, production, installation, commissioning, operation, maintenance, decommissioning, and recycling of electrical/electronic/programmable electronic safety-related systems.
Our expertise spans across various sectors including automotive, industrial machinery, and medical devices. By leveraging these standards, we ensure that our testing services meet the highest industry expectations. For HVAC equipment manufacturers, this means achieving compliance with regulations specific to their field while adhering to broader functional safety principles.
