ČSN EN IEC 63261 This International Standard provides requirements for the E&I objects of a digital 3D plant model, used in the engineering phase to design and construct a process plant and its instrumentation. It provides guidance how to model plants and their electrical and instrumentation equipment. This document also specifies the content and the possible output of the 3D plant model at project milestones. This document can be used by the contractual partners to agree upon the content of the 3D plant model to be delivered at specified milestones. This document does not specify the transfer and format of digital 3D plant models. This document does not specify definitions or instructions to equipment representations and details of elements in the 3D plant model not belonging to electrical and instrumentation domains.

ČSN EN ISO 7944 This document specifies reference wavelengths to be used for the characterization of optical materials, optical systems and instruments, and ophthalmic lenses. It defines the associated principal refractive indices and principal dispersions, as well as the Abbe numbers with regard to these reference wavelengths and principal dispersions.

ČSN ISO 10262 Tato mezinárodní norma stanovuje jednotný, opakovatelný zkušební postup a požadavky na provedení pro hodnocení ochranných krytů obsluhy, které jsou vystaveny zatížení. Tyto ochranné kryty jsou obvykle určeny k tomu, aby poskytovaly obsluze lopatových rýpadel přiměřenou ochranu před předměty (např. kameny a úlomky), které by jinak pronikly na stanoviště obsluhy zepředu nebo shora. Platí pro hydraulická lopatová rýpadla, jak jsou definována v ISO 7135, pokud jsou vybavena ochranným krytem (kryty) na stanovišti obsluhy.

ČSN EN 17930 This document specifies the reference architecture for a hyperloop system. It specifies the functions of each (sub)system classifying them in different functional blocks, their different possible implementations, and highlights the interactions between them. The interfaces of the transportation system based on interactions are listed, whether it be internal interfaces or exterior interfaces. The characterization considers the technical as well as operational features of the transport service.

ČSN EN 2714-014 This document specifies the characteristics of UV laser printable DR family, 1 to 11 cores, taped, screened (braided) and jacketed electrical lightweight cables for use in the on-board electrical systems of aircraft, at operating temperatures between -55 °C and 260 °C. Nevertheless, if needed, -65 °C is also acceptable as shown by cold test. It is possible to mark these cables by qualified compatible marking, in line with EN 3838.

ČSN EN 4681-004 This document specifies the characteristics of UV laser printable electrical lightweight wires ADA family for use in the on-board 115 V (phase to neutral) or 200 V (phase-to-phase) AC, 28 VDC electrical systems of aircraft at operating temperatures between -65 °C and 180 °C. These cables are demonstrated to be arc resistant in sizes AWG 26 to 14 (115 VAC/200 VAC). In addition, these cables are suitable for use at 230 VAC/400 VAC in pressurized zones only when installed to take account of possible short circuit effects. Other electrical system configurations are the responsibility of the users. It is also possible to mark these cables by qualified compatible marking which satisfies the requirements of EN 3838:2022.

ČSN EN 4681-003 This document specifies the characteristics of UV laser printable electrical lightweight wires AD family for use in the on-board 115 V (phase to neutral) or 200 V (phase to phase) AC, 28 VDC electrical systems of aircraft at operating temperatures between -65 °C and 180 °C. These cables are demonstrated to be arc resistant in sizes AWG 24 to 14 (115 VAC/200 VAC). In addition, these cables are suitable for use at 230 VAC/400 VAC in pressurized zones only when installed to take account of possible short circuit effects. Other electrical system configurations are the responsibility of the users. It is also possible to mark these cables by qualified compatible marking which satisfies the requirements of EN 3838:2022.
