ČSN EN 13155+A1 This document specifies safety requirements for the following non-fixed load lifting attachments for cranes, hoists and manually controlled load manipulating devices: a) plate clamps; b) vacuum lifters: 1) self-priming; 2) non-self-priming (pump, venturi, turbine); c) lifting magnets: 1) electric lifting magnets (battery fed and mains-fed); 2)permanent lifting magnets; 3) electro-permanent lifting magnets; d) lifting beams; e) C-hooks; f) lifting forks; g) clamps; h) lifting insert systems for use in normal weight concrete, as defined in Clause 3. This document does not give requirements for: - non-fixed load lifting attachments in direct contact with foodstuffs or pharmaceuticals requiring a high level of cleanliness for hygiene reasons; - hazards resulting from handling specific hazardous materials (e.g. explosives, hot molten masses, radiating materials); - hazards caused by operation in an explosive atmosphere; - hazards caused by noise; - hazards relating to the lifting of persons; - electrical hazards; - hazards due to hydraulic and pneumatic components. For high risk applications not covered by this standard, !EN 13001 2:2021", 4.3.2 gives guidance to deal with them. This document covers the proof of static strength, the elastic stability and the proof of fatigue strength. This document does not generally applies to attachments intended to lift above people. Some attachments are suitable for that purpose if equipped with additional safety features. In such cases the additional safety features are specified in the specific requirements. This document does not cover slings, ladles, expanding mandrels, buckets, grabs, or grab buckets. This document does not cover power operated container handling spreaders, which are in the scope of EN 15056. This document is not applicable to non-fixed load attachments manufactured before the date of its publication.

ČSN EN 15273-4 The gauges included in this document have been developed for application on mainline railway networks using various track gauges. Other vehicles and networks are outside the scope of this document, but the rules may be applied to them with some adjustments and agreement of the share of responsibility between rolling stock and infrastructure. This document is a catalogue of reference profiles and their associated rules for the defined gauging process. This document is intended to be used with EN 15273-1:2025, EN 15273-2:2025 and EN 15273-3:2025. This document is not applicable to the gauges "S" and "T" for track gauge 1 520 mm.

ČSN EN IEC 63208 This document applies to the main functions of switchgear and controlgear and their assemblies, called equipment, in the context of operational technology (OT 3.1.34). It is applicable to equipment with wired or wireless data communication means and their physical accessibility, within their limits of environmental conditions. It is intended to achieve the appropriate physical and cybersecurity mitigation against vulnerabilities to security threats. This document provides requirements on the appropriate security risk assessment to be developed including the attack levels, the typical threats, the impact assessment and the relationship with safety, levels of exposure of the communication interface and the determination of the equipment security level, assessment of the exposure level of the communication interfaces, assignment of the required security measures for the equipment, countermeasures for the physical access and the environment derived from ISO/IEC 27001, countermeasures referring to IEC 62443-4-2 with their criteria of applicability, user instructions for installation, operation and maintenance, conformance verification and testing, and security protection profiles by family of equipment (Annex E to Annex I).
