What is functional safety engineer?

At its simplest functional safety is the part of the overall safety relating to the equipment under control and its associated control system that depends on the correct functioning of the safety-related system. Functional safety is achieved when all the specified safety functions, of the safety-related system, can satisfy their required safety performance.

1. Functional safety is undertaken by active systems.
2. We recognise IEC 61508 and related standards (e.g., IEC 61511 and IEC 62061) as the benchmark for achieving functional safety and manageing risks in a proportionate way.
3. IEC 61508 sets out the requirements for ensuring that systems are designed, implemented, operated and maintained to provide the required safety integrity level (SIL).

Four SILs are defined according to the risks involved in the system application, with SIL4 being used to protect against the highest risks. The standard specifies a process that can be followed by all links in the supply chain so that information about the system can be communicated using common terminology and system parameters.

Some organisations or people can find functional safety and IEC 61508 compliance as a daunting prospect. One of the key principles of the Association is to promote and support the best routes for compliance to IEC 61508 and related standards. Please review the CASS webpages and consider joining the Association if you are new to functional safety ( join us ).

What is a Safety-Related System? Typically a system will comprise a sensor which provides information on the value of a variable, a processor which compares the value with a predetermined limit and initiates action and an actuator which either corrects the variable or performs an emergency function.

1. Apart from the reference to danger, this description could be applied equally to the process controls for the equipment performing its function.
2. In the past it was regarded as essential that the safety function operated independently from the process function.
3. The advent of microprocessors enabled vast amounts of data to be collected and analysed in real time thus providing the possibility of sophisticated safety systems including such features as self-diagnosis.

With many different parties involved in the specification, design, manufacture, installation, operation and maintenance of safety systems, the need for a standardised approach was recognised and IEC 61508 is the result. What is Functional Safety Engineering? Functional safety engineering is where studies are performed with the objective of providing assurance that safety-related products, devices and systems deliver the appropriate level of risk reduction, protection or mitigation.

Manage and plan the safety-related requirements and the associated systems / controls; Manage and plan the safety-related requirements and the associated software; Reduce the likelihood of systematic failures; Reduce the likelihood of random hardware failures; Enhance the overall safety management (incl. operation and maintenance); and Support demonstration of continuous improvement in safety culture.

Functional safety engineering can generally be considered as a combination of studies, analysis, audits, assessments, and reviews to enable an engineering judgement to assure functional safety. Learn more about Functional Safety (IEC) Learn more at the HSE COMAH site

What is TUV certified?

What Does TÜV Product Certification Mean? – Highly recognized worldwide as a trademark of trust and quality, a TÜV certification ensures that a product, service, or process has been tested for safety and that it complies with the requirements of national, regional, and international regulations.

Is TUV certification accepted in USA?

TÜV Rheinland of North America is accredited as a Nationally Recognized Testing Laboratory (NRTL), by OSHA (The Occupational Safety and Health Administration) in the United States, and as a Product Certification Body by SCC (Standards Council of Canada) in Canada.

Are TUV and UL the same?

Comparison of TUV and UL Certification – While both TUV and UL certifications provide assurance of product safety and quality, there are some differences between the two. TUV certification is based on European standards, while UL certification is based on American standards.

• This means that TUV-certified products may not meet the same requirements as UL-certified products and vice versa.
• TUV certification focuses on product safety and reliability, while UL certification focuses on both product safety and sustainability.
• This means that UL-certified products must meet not only safety and quality standards but also environmental standards, such as energy efficiency and sustainability.

The cost of obtaining TUV and UL certification may also vary, with UL certification typically being more expensive. This is because the UL certification process is more comprehensive and involves more testing and monitoring. However, the additional cost can be offset by the increased market competitiveness and improved brand image that comes with UL certification.

Ultimately, the choice between TUV and UL certification depends on your specific needs and market focus. If you are looking to sell your solar cable product in Europe, TUV certification may be the better option. On the other hand, if you are looking to sell your product globally and have a focus on sustainability, UL certification may be the better choice.

In conclusion, choosing between and is a crucial decision that can impact your product’s safety, quality, and marketability. Both certifications provide assurance of product safety and quality, but the best option for your product will depend on your specific needs and market focus.

What is the difference between TUV and CE?

TUV stands for Technical University of Vienna, and it is a certification that an item is safe for use in its intended environment. The CE certification stands for Conformité Européenne, which means that the item has been tested and is deemed safe for use.

What is the difference between product safety and functional safety?

Image Autonomous vehicles, electrification, connected cars, ride sharing are some of the terms that we have been increasingly exposed to in the automotive space. A space once wholly occupied by the car manufacturing heavyweights and its dedicated supply chain.

1. It is now possible to say that the space is no longer so exclusive and has opened up to solution providers, large and small.
2. The newer players are bringing in vital technologies that are defining the trajectory of the automotive industry, but a vital question still remains: What about safety in this ‘new’ normal? In the automotive industry, safety generally means being protected from danger, risk, or injury.

In tangible terms, a company that sells a car to the consumer must ensure that the car is not the cause of unacceptable risk or physical injury to the road users including the car owner. For example, a product could have sharp edges that can cause cut wounds resulting in bleeding or the product could become hot causing burn wounds to the user.

Consider the case of brake lights in the back of our cars. The brake lights illuminate when the driver presses the brake pedal to indicate a reduction in speed to the driver behind. If we consider the potential risks of such a product, the brake light bulbs can become hot resulting in burn wounds for a pedestrian accidentally touching it or there could be the risk of electric shock in case of exposed wires or contacts.

But these high level risks can be mitigated with the use of protective coverings or insulations. There is also a different class of failures with the brake lights that is not so straight forward. With the expansion of intelligent systems, electronic control units are increasingly used in cars. In the case of smart braking light system, the brake lights would be connected to a smart controller that detects the depression of the brake pedal by the driver and activates the brake lights.

If the controller fails to work properly and misses to detect the depression of the brake pedal, the brake lights would not be activated. Such a failure during high speed driving could result in the driver of the following car failing to notice that that the car before is slowing down resulting in a possible accident.

In this situation, the smart brake light system has failed electronically (failure of the overall system caused by an electronic malfunction) resulting in a crash. The brake lights have themselves not been involved in harming the user, but their malfunctioning behavior has resulted in a crash that could lead to injuries to user and material damage.

• Preventing these types of failures requires dedicated design principles and methods to be used when conceptualizing, designing, testing, and manufacturing the product.
• The challenge of making a safe car runs deeper than just the braking lights.
• There are far more complex systems that are involved in the control and execution of primary function of a vehicle (driving, accelerating, decelerating), safety and comfort functions.

With the advent of Advanced driver assistance features like autonomous driving, the systems are getting more and more complex. It is the responsibility of the OEMs and the solution providers to ensure that the smart systems are inherently safe and also continue operating safely without causing any direct or indirect harm to the road users.

What is the role of functional engineer?

Key responsibilities: Plan one or more of the following: application, integration, user acceptance and operational acceptance tests. Determine testing environment requirements. Manage work throughout test preparation and test execution to ensure that testing is on time and within budget.

What is the role of functional safety?

Functional safety is part of the overall safety of a system or piece of equipment that depends on automatic protection. This automatic protection system needs to respond correctly to its inputs. And it should have predictable responses to failure.

Who is a functional engineer?

Deliver solutions, not components – Functional programmers (and software engineers in general) like to tinker with code. But functional engineers balance perfecting the code with ensuring the overall system is delivered and maintainable. Considering the system as a whole is not simply a matter of considering all its smaller parts. There are operational considerations, documentation, integration of all the services, migration, then finally the roll-out to customers. That’s a lot to do beyond just the coding itself.

• And it all needs to fit into the time between now and the delivery date.
• We can do ourselves a favor by applying functional programming principles not just to the code, but to the architecture of our systems.
• For example, some of the work in perfecting a small microservice ends up going to waste because microservices are meant to be thrown out and rewritten if they no longer meet your needs.

By contrast, applying functional concepts such as append-only stores and event-based architectures helps our efforts live much longer. This, in turn, lets us spend more energy perfecting the system as a whole, instead of rabbit-holing on individual components.
