In presented paper perform prototype machine which consist of two independent motion axis equipped with force sensors. Used force sensors provide control of forming connection. Special design of the machine provide to make tensile strength test on it. Prepared nine samples to carried out tests, which revealed the influence between change of jaws displacement during plastic deformation and strength of that joint. Created prototype stand base on two independent drive units allow to make that connection possible. Choosing right parameters leads to generate joints which are more than twice stronger than basic sample reaching more than 920N.

Content available The method of selecting the interval of functional tests taking into account economic aspects and legal requirements

The article discusses the problem of choosing the optimal frequency of functional tests, taking into account the reliability and law requirements, but also the impact of business aspects in the company. The subject of functional test interval is well described for purposes of the process industry. Unfortunately, this is not the case for the machinery safety functions with low demand mode. This is followed by a presentation of the current business approach, which, in order to achieve industrial excellence, monitor their performance through the appropriate selection of key performance indicators. In addition, companies are increasingly exploring potential risks in the following areas: new challenges in advanced risk management, including the perception of the company’s facilities as a safe workplace insight of customers and business partners. Eliminating potential hazards is increasingly taking into account, especially the impact of human activity and its interaction with machines. The case study has been presented based on the machines used for the production of tire semi-finished products. In this article, the authors propose a solution for selecting the interval of functional tests of safety functions and additional machine protection measures as a compromise to achieve satisfactory results in terms of safety requirements, performance and legal requirements.

Content available Integrated functional safety and cybersecurity. Analysis method for smart manufacturing systems

This article addresses integrated functional safety and cybersecurity analysis with regard to: the generic functional safety standard IEC 61508 and the cyber security standard IEC 62443 concerning an industrial automation and control system (IACS). The objective is to mitigate the vulnerability of information technology (IT) and operational technology (OT) systems, and reduce relevant risks taking into account a set of fundamental requirements (FRs). A method is proposed for determining and verifying the performance level (PL) or the safety integrity level (SIL) of defined safety functions, and then validating these levels depending on the security level (SL) of a particular domain,e.g.a safety related control system (SRCS). The method is general in the sense that it is based on risk graphs prepared for individual risk and/or societal/group risk with regard to the criteria defined.

This article addresses some functional safety assessment procedures with cybersecurity aspects in critical industrial installations with regard to the functional safety requirements specified in standards IEC 61508 and IEC 61511. The functional safety management includes hazard identification, risk analysis and assessment, specification of overall safety requirements and definition of safety functions. Based on the risk assessment results, the safety integrity level (SIL) is determined for consecutive safety functions. These functions are implemented within the industrial control system (ICS) and/or the distributed control system (DCS) that consists of the basic process control system (BPCS) and/or the safety instrumented system (SIS). The determination of the required SIL related to the required risk mitigation is based on the semi-quantitative evaluation method. Verification of the SIL for the considered architectures o fthe BPCS and/or the SIS is supported by probabilistic models with appropriate data and model parameters including cybersecurity related aspects. The proposed approach is illustrated on the example of critical industrial installations.
