ČSN ETSI EN 301 489-4 V2.2.1 The present document, together with ETSI EN 301 489-1 [1], covers the assessment of Fixed Radio Links, and ancillary equipment in respect of ElectroMagnetic Compatibility (EMC). Technical specifications related to the antenna port of the radio equipment are not included in the present document. Such technical specifications are found in the relevant product standards for the effective use of the radio spectrum. The present document specifies the applicable test conditions, performance assessment and performance criteria for Analogue and Digital Fixed Radio Links operating as fixed Point-to-Point, and Point-to-Multipoint systems as defined in annex A, including the associated ancillary equipment. Examples of Fixed Radio Links are given in annex A. In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present document and ETSI EN 301 489-1 [1], the provisions of the present document take precedence. The processing and protection switch, (de)modulator, transmitter, receiver, RF filters, branching networks, feeders are covered by the present document. The multiplexing and/or de-multiplexing elements are covered if they form part of the transmitter, receiver and/or transceiver. The environmental classification and the emission and immunity requirements used in the present document are as stated in ETSI EN 301 489-1 [1], except for any special conditions included in the present document.

ČSN ETSI EN 301 841-3 V1.2.1 The present document applies to VDL Mode 2 ground-air digital communications using Differential Eight Phase Shift Keying (D8PSK), intended for channel increments of 25 kHz. The VDL Mode 2 system provides data communication exchanges between aircraft and ground-based systems, operating in the VHF band (117,975 MHz to 137,000 MHz). The scope of the present document is limited to ground based stations. NOTE 1: The VDL Mode 2 can be used as an Air/Ground sub-network of the Aeronautical Telecommunication Network (ATN) using a band with AM(R)S spectrum allocation. The present document is intended to cover the provisions of Directive 1999/5/EC [i.2] (R&TTE Directive), article 3.2, which states that "... radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference". In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the R&TTE Directive may apply to equipment within the scope of the present document. NOTE 2: A list of such ENs is included on the web site http://www.newapproach.org. Compliance with relevant aviation regulations may also be required before equipment within the scope of the present document can enter into service.

ČSN EN 16617 This European Standard specifies all significant hazards, hazardous situation and events as listed in Clause 4, relevant to stationary and displaceable manual horizontal cutting cross-cut circular sawing machines with one saw unit (manual radial arm saws), hereinafter referred to as "machines", designed to cut solid wood, chipboard, fibreboard, plywood and also these materials if they are covered with plastic edging and/or plastic laminates, when they are used as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. NOTE 1: For the definition of stationary and displaceable machine, see 3.2.3 and 3.2.4. The requirements of this document apply to all machines whatever their method of control e.g. electromechanical and/or electronic. This document does not apply to: a) machines set up on a bench or a table similar to a bench, which are intended to carry out work in a stationary position, capable of being lifted by one person by hand; the bench can also be an integrated part of the machine if it consists of hinged legs which can be extended down; NOTE 2: Transportable motor-operated electrical tools are dealt with in EN 61029-1:2009 together with IEC 61029 2 2:1993. b) machines fitted with hydraulically powered machine actuators; c) machines fitted with powered work-piece positioning; d) machines fitted with the facility for either ripping, milling (including trenching and grooving), sanding and/or drilling; e) machines equipped with more than one saw spindle speed; NOTE 3: A standard to cover machines that can be used for ripping and moulding will be considered at the next revision. NOTE 4: Semi-automatic and automatic horizontal cutting cross-cut circular sawing machines with one saw unit (radial arm saws) are dealt with in EN 1870-11:2003+A1:2009. f) machines with integrated feed. This document is not applicable to manual horizontal cutting cross-cut circular sawing machines with one saw unit (manual radial arm saws) which are manufactured before the date of its publication as EN.

ČSN EN 16661 This European Standard applies to the tyre pressure gauges (TPG) which operate using pressure equipment (devices used in fixed or mobile installations) to inflate the tyres of road using vehicles (M1 and M2 categories) and which may be capable of interacting with vehicles equipped with tyre pressure monitoring systems (TPMS) whereby the TPG may be steered by the TPMS/vehicle. To set the correct tyre inflation, this European Standard defines requirements and processes for the interoperability of TPG with TPMS/vehicle, through standardized interfaces and data exchange formats allowing advanced information, management and control systems between TPG and TPMS/vehicle. The architecture is open and scalable to support the different levels of interoperability (from full interoperability to fully manual). This European Standard does not define communication protocols (works specifically made under M/453 European mandate). This European Standard may be applied to all TPG categories referenced in EN 12645. The driver/operator is considered as being responsible for the validation of the parameters and tyre pressure. This European Standard will be applicable upon development of Infrastructure solution (V2I-I2V communication solutions)

ČSN EN 60404-5 ed. 2 Tato norma definuje metody měření magnetické indukce, magnetické polarizace a intenzity magnetického pole a také určování demagnetizačních křivek a zpětných přímek materiálů, permanentních magnetů, definovaných v IEC 60404-8-1, u kterých se předpokládá, že jejich vlastnosti jsou v celém jejich objemu homogenní. Vlastnosti magnetického systému nejsou závislé jen na vlastnostech materiálů permanentních magnetů, ale také na rozměrech, vzduchové mezeře a ostatních prvcích magnetického obvodu. Metody popisované v této normě se týkají měření magnetických vlastností celých uzavřených magnetických obvodů.

ČSN EN 62056-1-0 This part of IEC 62056 provides information on the smart metering use cases and on architectures supported by the IEC 62056 DLMS/COSEM series of standards specifying electricity meter data exchange. It describes the standardization framework including: the principles on which the standards shall be developed; the ways the existing standards shall be extended to support new use cases and to accommodate new communication technologies, while maintaining coherency; the aspects of interoperability and information security. It also provides guidance for selecting the suitable standards for a specific interface within the smart metering system.

ČSN EN 62570 1.1 This international standard applies to the practice of marking of items that might be used in the magnetic resonance (MR) environment. 1.2 The purpose of this practice is to mark items that might be brought into the MR environment and to recommend information that should be included in the marking. 1.3 The standard specifies the permanent marking of items, which are used in an MR environment, by means of terms and icons. 1.4 MR image artifacts are not considered to be a performance issue and so are not addressed in this international standard practice (see X1.5). 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of his standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
