ČSN EN 6049-008 This European Standard specifies the characteristics of post installation flexible self-wrapping EMI shielding protection sleeves for electrical cable and cable bundles made from meta-aramid fibres for the external sleeve, and nickel copper plated braid as the internal layer and provided with a water repellent protection for aerospace application.

ČSN EN 2346-005 This European Standard specifies the characteristics of light weight fire proof, unscreened, electrical cables for use in the on-board electrical systems of aircraft at operating temperature between - 65 °C and 260 °C. This cable has not been demonstrated to be arc resistance at a.c.voltages above 200 V rms (network 115/200 V rms). Single core is UV laser printable in accordance with EN 3838; UV laser markability is not mandatory for multicore cables.

ČSN EN 4674-004 This European Standard specifies the characteristics of flexible 10 kA self-wrapping shielding (EMI) protection sleeves, to be installed mainly outside pressurized areas on electrical cables or cable bundles, made from nickel plated copper strands and PPS (polyphenylene sulphide) monofilament.

ČSN EN 4708-104 This European Standard specifies the required characteristics for a heat-shrinkable, semi-rigid polyvinylidene sleeving for use in aircraft electrical systems at operating temperatures between - 55 °C and 175 °C. This sleeving is basically transparent, but may be tinted. It is semi-rigid, tough and abrasion resistant, and is suitable for use where strain relief and mechanical protection are required, or where their transparent properties are desirable. These sleevings are normally supplied with internal diameters up to 25,4 mm for shrink ratios of 2:1. Sizes other than those specifically listed in this European Standard may be available. These items shall be considered to comply with this European Standard if they comply with the property requirements listed in Tables 2, 3 and 4 except for dimensions and mass.

ČSN EN IEC 62677-1 This document is applicable to heat shrinkable low and medium voltage moulded shapes in a range of configurations and materials suitable for insulation, environmental sealing, mechanical protection, electrical conductance, anti-tracking and strain relief for power cable terminations, joints and stop ends. It specifies the test methods and material requirements. The most commonly available shapes are as shown in the Annex A. Materials which conform to this document meet established levels of performance. However, the selection of a material by a user for a specific application will be based on the actual requirements necessary for adequate performance in that application and will not be based on this document alone. These moulded shapes are designed to be used in low and medium voltage cable accessories and as such electrical performance will be proven as part of the assembly. Examples of this are described in EN 50393, HD 629.1 and IEC 60502-4.

ČSN EN 62561-5 ed. 2 Tato část IEC 62561 specifikuje požadavky a zkoušky pro revizní skříně zemničů (skříně zemničů) a pro provedení zemničů. Součásti systému ochrany před bleskem (LPSC) mohou být použity také v prostředí s nebezpečím výbuchu. Přitom by měly být zohledněny zvláštní požadavky na instalaci jednotlivých součástí, v těchto podmínkách.
