ČSN EN ISO 11126-8 This document specifies requirements for olivine abrasives, as supplied for blast-cleaning processes. It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in this document apply to abrasives supplied in the "new" condition only. They do not apply to abrasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO 11127. NOTE: Although this document has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504-2.

ČSN EN 17002 Norma určuje minimální požadavky, které musí splnit obsah specifikace postupu žárového nástřiku. Cílem je, aby použití specifikace postupu žárového nástřiku vedlo ke splnění požadavků specifikace povlaku. Specifikace postupu žárového nástřiku je dokument kriticky důležitý pro zajišťování kvality v průběhu výroby při zhotovování žárově stříkaného povlaku. Zkoušky a jejich rozsahy platnosti mají být vymezeny výrobcem povlaku v odděleném plánu zkoušek podle požadavků uvedených ve specifikaci povlaku. Ustanovení týkající se specifikace žárově stříkaného povlaku jsou uvedena v ČSN EN 17001.

ČSN EN ISO 24134 This International Standard specifies the safety requirements for controls and control systems for the following automated functions of industrial trucks: - steering (excluding direct mechanical guidance); - travel; - lifting and lowering operations; - load manipulations, e.g. rotation, reach, slewing, tilting, clamping; - combination and/or sequence of the above movements. NOTE: The control system is generally part of the truck but can include components external to the truck, e.g. the means of guidance for automated steering. This International Standard is intended for use in conjunction with one or more of the applicable parts of ISO 3691. This International Standard is not applicable to, and does not include, requirements for the following: - safety equipment (e.g. devices for height limitation, speed limitation) used to override operator control; - operation in severe conditions (e.g. extreme climates, freezer applications, strong magnetic fields); - operation in environments subject to special rules (e.g. potentially explosive atmospheres); - electromagnetic compatibility; - transportation of passengers; - handling of loads, the nature of which could lead to dangerous situations (e.g. molten metals, acids/bases, radiating materials). Limitations in the scopes of the applicable parts of ISO 3691 also apply to this International Standard.

ČSN EN 4839-003 This European Standard specifies the required characteristics for three-pole, arc fault circuit breakers, rated currents from 3 A to 25 A, switching capacity 65 In, for use in aircraft electrical systems. Their operating temperatures are between -40 °C to 85 °C at a maximum altitude of Z = 15 000 m. The thermal protection is temperature compensated and operates between -55 °C and 125 °C. These arc fault circuit breakers are operated by a push-pull type single pushbutton (actuator), with delayed action "trip-free" tripping. They will continue to function up to the short-circuit current.

ČSN EN 4611-006 This European Standard specifies the characteristics of UV laser printable, silver plated copper conductor electrical cables Crosslinked Ethylene Tetra Fluoro Ethylene co-polymer (XLETFE) family for use in the on-board electrical systems of aircraft operating at temperatures between - 65 °C and 150 °C. The voltage rating is 600 V rms at sea level. This insulation system has been used in aerospace applications using 115 V ac (phase-to-neutral) 400 Hz and 28 V dc. Verification of the suitability of cables for use in other electrical systems is the responsibility of the user. These cables are suitable for airframe use. In case of conflict between this standard and other referenced documents the requirements of this standard shall take precedence.
