ČSN EN ISO 18243 This document specifies the test procedures for lithium-ion battery packs and systems used in electrically propelled mopeds and motorcycles. The specified test procedures enable the user of this document to determine the essential characteristics on performance and safety of lithium-ion battery packs and systems. It is also possible to compare the test results achieved for different battery packs or systems. This document enables setting up a dedicated test plan for an individual battery pack or system subject to an agreement between customer and supplier. If required, the relevant test procedures and/or test conditions of lithium-ion battery packs and systems are selected from the standard tests provided in this document to configure a dedicated test plan. NOTE 1 - Electrically power-assisted cycles (EPAC) cannot be considered as mopeds. The definition of electrically power-assisted cycles can differ from country to country. An example of definition can be found in Reference [7]. NOTE 2 - Testing on cell level is specified in the IEC 62660 series.

ČSN EN 9241 The scope of the present document is to provide the elements needed for elaborating the programme execution logic and drafting the execution plan for the realization of a product. NOTE 1 - In this document, the term "logic" alone is sometimes used for "execution logic". NOTE 2 - In this document, the term "product" is used to designate the object of the program concerned, and the term "system" is used to designate the product for anything related to system engineering. NOTE 3 - The product is also considered a "system-of-interest" and its enabling systems are also taken into account. The execution logic and plan enable customers/suppliers to reach an agreement on how their respective processes and activities can be organized. The aim is to enable each actor in the programme to manage their activities with sufficient visibility of the sequencing of the other stakeholders' activities. This document belongs to the documents supporting EN 9200 relating to the programme management specification. The present document describes the principles of programme execution logic and defines the corresponding management requirements. This description is supplemented: - on the one hand, in terms of execution logic principles, by: - the challenges of a basic logic common to all actors (synchronization); - the applicable criteria to set up this basic logic; - the translation of this logic into the programme processes; - on the other hand, in terms of implementing the execution logic, by: - the procedures for practical implementation of the management requirements defined in EN 9200; - adaptations of the logic according to the various constraints and specificities of the programme, and justification of these adaptations; - the consistency between the basic logic at system level and the logics at subsystem and constituent levels. The breakdown of clauses as used in this document gives a gradual understanding of the approach to be adopted to construct an execution logic. For instance: - Clause 5 presents the end-purpose of a programme execution logic as well as the associated basic concepts and the constituents of this logic; - Clause 6 describes and characterizes the process for building the logic; - Clause 7 concerns change control to the execution logic; - Clause 8 concentrates on the importance of capitalization and lessons learned. This document is applicable to aeronautical, space and defence programmes. The principles can be extended to other areas of activity. It is applicable to realization of a single product, of several samples or of a series. It is applicable to any customer/supplier level, while ensuring consistency between successive levels. The principles described concern all programme actors, from initial expression of need through to closure of the programme.

ČSN EN 50176 ed. 3 1.1 This document specifies the electrical requirements for the design of automatic electrostatic application systems for liquid coating materials which can be ignited in an atomised state, used within a temperature range from 5 °C to 40 °C. This document considers automatic electrostatic application systems for processing ignitable liquid coating materials, where the conductivity of the complete system is limited up to 50 nS/cm. Together with additional measures like e.g. potential separation systems, these requirements can also be applied to ignitable liquid coating materials, where the conductivity of the complete system is limited up to 2 000 µS/cm. Ignition hazards related to the generated explosive atmosphere and the protection of persons against electric shock are considered. 1.2 This document specifies - requirements for an interface to machinery according to EN 16985:2018, - additional requirements for machinery covered by EN 1953:2025 and EN 12621:2025. 1.3 This document also specifies requirements for a safe operation of electrostatic application systems, including the electrical installation. The requirements consider both the processing of coating materials and the cleaning and purge processes. 1.4 This document applies to three types of spraying systems; see 5.1.1. Spraying systems are classified as equipment of group II, category 2G (for intended use in zone 1 or zone 2) or category 3G (for intended use in zone 2). Only electrostatic spraying systems operating with a d.c. sinusoidal ripple of not more than 10 % of the r.m.s. value are considered. 1.5 For electrostatic application systems used in food and pharmaceutical industry, additional requirements may apply. 1.6 This document does not apply to - potential separation systems; - selection, installation and application of other electrical and non-electrical equipment in areas with explosion hazard, see EN 60079-14:2014 and EN 16985:2018; - quality assurance systems for electrostatic spraying equipment (see EN ISO/IEC 80079-34:2020, ZB.11).
