ČSN EN 15714-5 This document provides basic requirements for piston type pneumatic linear actuators for industrial valve, both double acting and single acting, used for on-off and modulating control duties. It includes criteria, method and guidelines for design, qualification, corrosion protection, control and testing. It does not apply to diaphragm actuators and to pneumatic actuators which are integral parts of control valves. Other requirements, or conditions of use, different from those indicated in this document, are subject to agreement, between the purchaser and the manufacturer/supplier, prior to order.

ČSN EN ISO 6346 1.1 This document provides a system for the identification and presentation of information about freight containers. The identification system is intended for general application, for example in documentation, control and communications (including automatic data processing systems), as well as for display on the containers themselves. The methods of displaying identification and certain other data (including operational data) on containers by means of permanent marks are included. 1.2 This document specifies: a) a container identification system, with an associated system for verifying the accuracy of its use, having: - mandatory marks for the presentation of the identification system for visual interpretation, and - features to be used in optional Automatic Equipment Identification (AEI) and electronic data interchange (EDI); b) a coding system for data on container size and type, with corresponding marks for their display; c) operational marks, both mandatory and optional; d) physical presentation of marks on the container. 1.3 The terms "mandatory" and "optional" in this document are used to differentiate those ISO marking provisions which shall necessarily be fulfilled by all containers from those which are not required of all containers. The optional marks are included to further comprehension and promote uniform application of the optional mark. If a choice has been made to display an optional mark, the provisions laid down in this document relating to the mark shall be applied. The terms "mandatory" and "optional" do not refer to requirements of any regulatory body. 1.4 This document applies to all freight containers covered by International Standards ISO 668, parts 1 to 5 of ISO 1496, ISO 8323 and should, wherever appropriate and practicable, be applied: - to containers other than those covered by the International Standards mentioned in Clause 2; - to container-related and/or detachable equipment. NOTE 1 - Containers marked according to previous editions of ISO 6346 need not be re-marked. 1.5 This document does not cover temporary operational marks of any kind, permanent marks, data plates, etc. which may be required by intergovernmental agreements, national legislation or nongovernmental organizations. NOTE 2 - Some of the major international conventions whose container-marking requirements are not covered in this document are as follows: - International Convention for Safe Containers (1972, as amended) (CSC), International Maritime Organization (IMO); - Customs Convention on Containers 1956 and 1972, related to temporary admission and transport under customs seal. - Convention on Temporary Admission (Istanbul, 26 June 1990), related to temporary admission. It should not be assumed that this list is exhaustive. This document does not cover the display of technical data on tank containers (see ISO 1496-3), nor does it, in any way, include identification marks or safety signs for items of cargo which may be carried in freight containers.

ČSN EN IEC 60477-2 This part of IEC 60477 applies to resistors intended as laboratory AC resistors for use over a range of frequencies from DC up to a stated frequency which is not in excess of 1 MHz. Such resistors are hereinafter referred to as "AC resistors". In addition to satisfying the requirements of IEC 60477-1, resistors satisfying the requirements of this document are designed to have a small variation of resistance and a small phase displacement over the stated frequency range.

ČSN EN IEC 60477-1 This document applies to resistors intended for use as laboratory DC resistors (hereinafter referred to as "resistors") comprising standard resistors, single or multiple resistors of accuracy Classes 0,000 05 to 10 and single or multi-dial resistors of accuracy Classes 0,000 5 to 10. This document does not apply to: 1) resistors which are intended for use solely as permanently mounted circuit components, 2) resistors used on alternating current or on pulsed current, 3) active resistors, 4) series resistors and shunts which are considered as accessories of electrical measuring instruments in the relevant IEC document (examples of these are as follows). EXAMPLE 1 IEC 60051 series: Recommendations for direct acting indicating analogue electrical measuring instruments and their accessories. EXAMPLE 2 IEC 60258: Direct acting recording electrical measuring instruments and their accessories.

ČSN EN IEC 62660-3 ed. 2 Tato norma IEC 62660 stanovuje zkušební postupy a přejímací kritéria pro bezpečnostní vlastnosti lithium-ion akumulátorových článků a bloků článků používaných pro pohon elektrických vozidel (EV), včetně bateriových elektrických vozidel (BEV) a hybridních elektrických vozidel (HEV). Tento dokument stanoví základní bezpečnostní vlastnosti článků používaných v bateriových sadách a systémech za podmínek zamýšleného použití i za podmínek rozumně předvídatelného nesprávného použití nebo při nehodě, při běžném provozu EV. V této normě jsou bezpečnostní požadavky kladené na článek založeny na předpokladu, že články jsou v bateriové sadě a v bateriovém systému správně použity v mezích napětí, proudu a teploty stanovených výrobcem článku (provozní rozsah článku).

ČSN EN ISO 12863 This document specifies a test method for testing the capability of a cigarette, positioned on one of three standard substrates, to extinguish or to generate sufficient heat to continue burning, and thus potentially cause ignition of bedding or upholstered furniture. This document is only applicable to factory-made cigarettes that burn along the length of a tobacco column. This is a performance-based document; it does not prescribe any design features of the cigarette that can lead to improved or degraded performance in the test method. The output of this method has been correlated with the potential for cigarettes to ignite upholstered furniture.
