In general, a certificate is “accredited” when it has been issued by an accredited certification body. The main difference between an accredited certificate and a non-accredited one therefore lies in the level of formal recognition and independent trust in the certification process. Let us see what this means in the specific case of the SIL (Safety Integrity Level) certificate.
With the evolution of automation, cyber risks are impacting the functional safety of systems, with AI, IoT, and connectivity requiring integrated management from the very product design phase. System and machine manufacturers subject to European regulations (such as the Machinery Regulation and other related regulations including, for example, the AI Act, Data Act, Cyber Resilience Act, and NIS 2 Directive), whether CE-marked or not, can rely on international standards to ensure holistic compliance. In this article, we look at how safety and security regulations interact with one another and what is most advantageous to do in terms of system certification.

March 2023. Draft standard EN 17955 “Industrial valves - Functional safety of safety-related valves and actuators” is released, which has changed bynow the way functional safety is evaluated for all mechanical components of automated valve packages and actuators that are generally used in safety instrumented systems.
The key points of the ISO 26262 standard includes that of planning, coordinating and monitoring the progress of safety-related activities, as well as the responsibility of ensuring that confirmation measures are carried out throughout the Safety Life Cycle. Let's focus on a important aspect called the Functional Safety Concept.
The most recent of the certifications in the ISA family is ACSSA: Automation and Control Systems Security Assurance Certification. The upcoming opportunity is aimed at End Users to certify the cybersecurity of automation systems in use at their sites based on ISA/IEC 62443 standards.
While IEC 62443 is the standard that dictates best practices for cybersecurity of industrial automation and control systems, ISO 21434 addresses the automotive market. Let us take a look at the common features and differences between the two cybersecurity frameworks.
The TARA (Threat Analyses and Risk Assessment) analysis is the method specified by ISO 21434 for analyzing the threats and risks present in automotive digital security components, with the aim of ensuring the cybersecurity of newly approved cars.
ISO 21434 has a unique complexity, given also by the variety of terms introduced, compared to other standards.
Let us see what are the main definitions that, if you are an OEM, you can keep in mind when faced with a contract specification under ISO/SAE 21434.
The definitions are those available in the international version of ISO/SAE 21434.
While the New Machinery Regulation is approved, there is also some activity when it comes to harmonized standards relating to functional safety in the machine world. The final version of ISO 13849 Fourth Edition has been published: as promised in a previous article, find out here our comments.

These are two important standards that deal with the safety of electrical systems and frequency converters, respectively: IEC 61508 and IEC 61800-5-2. Here is a closer look at the safety guidelines for electrical systems and frequency converters.
The automotive sector is experiencing a sharp increase in the use of smart technologies, software, and vehicle connectivity, enabling us to evolve our understanding of mobility. But if the assurance of physical security and cybersecurity is now extensive and essential for most manufacturing and consumer sectors, the automotive sector is certainly no exception when it comes to cybersecurity.
If you are a manufacturer, and sometimes you have had difficulty with managing product configurations, it is because the regulations for functional security and cyber security expect Configuration Management requirements that are not easy to implement. Find out how to deal with the problem.

IEC 61511 is a technical standard related to functional safety which defines and identifies measures and techniques applicable to a safety system used in the process industry.
DIA is a reportable document which defines the relationship between the manufacturer and the supplier throughout the entire activity and depending on the intended assignment of the supplier.
Prior to the validation of an SRP/CS, which performs one or more safety functions, the specifications of the requirements for each safety function must be drawn up and verified to ensure their consistency and completeness for the intended use.
Safety-related control systems (called SCSs) implemented as a result of automation play a more significant role than ever in ensuring the overall safety of machinery. These SCSs also use increasingly complex electronic technologies, hence the need to update the IEC 62061 standard.
Digitalization in its various forms (e.g. the Internet of Things, Big Data and Artificial Intelligence) has undergone a massive expansion in recent years, influencing not just our everyday life, but also the whole industrial sector. Increasingly smart devices can work together in an autonomous way, making decisions based on large flows of data.
