1. What is the Functional Safety Engineer for ISO 13849 & IEC 62061 Training Course?

The Functional Safety Engineer for ISO 13849 & IEC 62061 training course is a 3-day programme that teaches engineers, technicians, and managers how to design and manage safety-related control systems in machinery. It covers key standards, including ISO 13849 and IEC 62061, with a focus on SIL, performance levels, diagnostics, and compliance. Participants can earn a TÜV SÜD certificate and apply for engineer-level registration in the Functional Safety Certification Program.

2. What is Functional Safety?

Functional safety is, simply put, “protecting a user from technology”. It also protects technology from users. However, more technically the definition of functional safety is: “Systems that lead to the freedom from unacceptable risk of injury or damage to the health of people by the proper implementation of one or more automatic protection functions (often called safety functions). A safety system consists of one or more safety functions.

3. What is functional safety, and why is it important in machinery systems?

Functional safety is a part of the overall safety of a system or equipment, which depends on the correct functioning of safety-related systems. It involves ensuring that machinery behaves as intended in response to inputs, avoiding hazardous events or controlling them effectively when failures or malfunctions occur.

In machinery systems, functional safety is crucial because it helps prevent accidents that could result in injury, damage, or fatalities. By implementing safety-related control systems (eg sensors, actuators, and logic controllers), functional safety ensures that risks associated with machinery operation are reduced to acceptable levels. This includes protecting operators, preventing equipment failure, and safeguarding the surrounding environment.

4. What are the key differences between ISO 13849 and IEC 62061?

ISO 13849 and IEC 62061 are both standards used to assess and implement functional safety in machinery, but they differ in their approaches and areas of application:

Scope:

ISO 13849: Focuses on safety-related parts of control systems (SRP/CS) for machinery, including mechanical, hydraulic, pneumatic, and electrical components.

IEC 62061: Applies specifically to electrical, electronic, and programmable electronic (E/E/PE) systems used in machinery.

Performance Metrics:

ISO 13849: Uses Performance Level (PL) to quantify the reliability of safety functions, which is based on parameters such as MTTFd (Mean Time to Dangerous Failure), diagnostic coverage, and system architecture.

IEC 62061: Uses Safety Integrity Level (SIL), which is part of a more detailed assessment based on Probability of Dangerous Failure per Hour (PFH), Safe Failure Fraction (SFF), and PFD (Probability of Failure on Demand).

Complexity:

ISO 13849: Simpler to apply and is generally used for less complex machinery systems with simpler safety requirements.

IEC 62061: More complex and suited to machinery with higher-risk applications, especially when using programmable electronics and complex control systems.

5. How do ISO 13849 and IEC 62061 relate to other machinery safety standards like IEC 61508?

IEC 61508 is a general standard for functional safety across all sectors, including machinery, process industries, and automotive, which provides a framework for the safety lifecycle of electrical, electronic, and programmable electronic systems (E/E/PE).

ISO 13849 and IEC 62061 are sector-specific derivatives of IEC 61508 tailored for machinery safety:

ISO 13849 deals with safety-related parts of control systems and is broader in terms of technology (mechanical, hydraulic, etc.), while IEC 62061 focuses on the electrical and programmable aspects.

Both standards use performance metrics (PL for ISO 13849 and SIL for IEC 62061) that align with the broader SIL concept found in IEC 61508, but adapted for the needs of machinery safety.

In summary, IEC 61508 is the overarching framework, while ISO 13849 and IEC 62061 are machinery-specific standards that apply its principles to ensure functional safety.

6. What is the purpose of ISO 13849 and IEC 62061, and when should each be applied?

ISO 13849 aims to ensure the functional safety of safety-related parts of control systems (SRP/CS), covering a broad range of technologies (electrical, mechanical, hydraulic, etc.). It is applied when dealing with less complex machinery where the control system is not primarily electronic or programmable. This standard is best for applications with simpler safety functions, often in smaller machines or equipment with straightforward safety needs.

IEC 62061 focuses on safety-related electrical, electronic, and programmable electronic control systems (SRECS) in machinery. It should be applied when the safety functions of the machinery are primarily electronic, especially in complex machinery or equipment involving programmable logic controllers (PLCs) and software-based safety controls.

7. What is the difference between our functional safety engineer and functional safety professional courses?

This course focuses on machine builders and system integrators handling complete machine function integration, while our functional safety professional training course is more geared towards manufacturing systems and devices for functional safety in the machinery sector.

If this course doesn't suit your needs, our functional safety professional training course may be more suitable.

TÜV SÜD additionally offers the opportunity to deliver this training as a dedicated in-house course, delivered solely to your organisation to meet your needs and requirements. To receive a quote and find out more information, please contact us at [email protected].
