ČSN ETSI EN 301 908-14 V7.1.1 The present document applies to the following radio equipment types: 1) Base Station for Evolved Universal Terrestrial Radio Access (E-UTRA). The present document covers requirements for E-UTRA Base Stations for 3GPP Release 8, 9, 10 and 11. This includes the requirements for E UTRA Base Station operating bands and E-UTRA CA operating bands from 3GPP Release 12. 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: A list of such ENs is included on the web site http://www.newapproach.org.

ČSN EN 494+A1 This European Standard specifies the technical requirements and establishes methods of control and test as well as acceptance conditions for fibre-cement profiled sheets and their fibre-cement fittings for one or more of the following uses roofing, internal wall finishes and external wall and ceiling finishes. For the purpose of this European Standard, fibre-cement profiled sheets are classified according to their height of corrugation and their mechanical characteristics. This European Standard covers fibre-cement profiled sheets reinforced with fibres of different type as specified in 5.1.1, with and without factory applied coating. This European Standard does not include calculations with regard to works, design requirements, installation techniques, wind uplift or rain proofing of the installed sheets.

ČSN ETSI EN 301 192 V1.6.1 The present document specifies transport and encapsulation protocols, and signalling for carrying general purpose data over DVB Transport Streams. The present document is designed to be used in conjunction with ETSI EN 300 468 [2]. Data broadcasting is an important extension of the MPEG-2 based DVB transmission standards. Examples are the download of software over satellite, cable or terrestrial links, the delivery of Internet services over broadcast channels (IP tunnelling), interactive TV, etc.

ČSN EN 4165-001 This European standard specifies the general characteristics, the conditions for qualification, acceptance and quality assurance, as well as the test programs and groups for rectangular connectors with one or multiple removable modules, intended for use in a temperature range from -55 °C to 175 °C continuous. This family of connectors is particularly suitable for aeronautic use in zones of severe environmental conditions on board aircraft, applying EN 2282. The maximum in-service temperature can be limited by maximum temperature of contacts.

ČSN P CEN/TS 16735 This Technical Specification defines a uniform structure and meaning for the information that fully represents postal rates for a broad variety of postal products in all mail categories. The postal rates definition is viewed as an important interface between posts and their customers and as such will benefit from standardization. Such representation of postal rates allows automated systems to uniformly use postal rates as they are introduced for new products or updated for existing postal products by postal operators. A postal rate file (PRF) is an XML document, which fully describes postal products rates. It contains all necessary and sufficient information for both postal operators and their customers to efficiently create, respectively acquire, update and process postal product rates. The structure, types and constraints of XML elements in an XML document are defined by an XML schema. The Extensible Postal Rates (EPR) schema is the XML schema that governs Postal Rate Files. This Technical Specification contains a complete description of the EPR schema, its hierarchical structure, information types and semantics of its elements. This Technical Specification neither defines nor constraints how postal rates are created by postal operators but rather provide a powerful and flexible tool that supports efficient rates definition, management and distribution. This Technical Specification does not define communication protocols that can be used by posts to distribute postal rates files to their customers. Suitable communication protocols are typically well known and already standardized (for example: Web Services, File Transport Protocol, email, etc.). The standard also does not define valuation of postal products as applied by postal operators and their customers.

ČSN EN 60939-3 This specification covers passive filters used to attenuate unwanted radio-frequency signals (such as noise or interference) generated from electromagnetic sources. Both single and multi-channel filters within one enclosure or which are built on a printed circuit board forming a compact entity are included within the scope of this specification. Filters constructed of capacitive elements where the inductance is inherent in the construction of the filter are within the scope of this specification. Similarly, filters constructed of inductive elements where the capacitance is inherent in the construction of the filter are also within the scope of this specification. It is up to the manufacturer to state whether a given component is to be designed as a capacitor, an inductor or a filter. Filters can include also other components like resistors and/or varistors or similar components This specification applies to passive filter units for electromagnetic interference suppression for which safety tests are appropriate. This implies that filters specified according to this specification will either be connected to mains supplies, when compliance with the mandatory tests of Table 3 is necessary, or used in other circuit positions where the equipment specification prescribes that some or all of these safety tests are required. This specification applies to passive filter units, which will be connected to an a.c. mains or other supply (d.c. or a.c.) with a nominal voltage not exceeding 1 000 V a.c., with a nominal frequency not exceeding 400 Hz, or 1 500 V d.c. NOTE: For a.c. use, IEC 60384-14 applies to capacitors which will be connected to a.c. mains with a nominal frequency not exceeding 100 Hz. This specification covers appliance filters (US) but does not cover facility filters, cordconnected filters or direct plug-in filters. These other filters will be covered by another sectional specification.

ČSN EN 61675-2 ed. 2 This part of IEC 61675 specifies terminology and test methods for describing the characteristics of GAMMA CAMERAS equipped with PARALLEL HOLE COLLIMATORS for planar imaging. Additional tests are specified for those GAMMA CAMERAS that are capable of planar wholebody imaging (PLANAR WHOLEBODY IMAGING EQUIPMENT) or SINGLE PHOTON EMISSION COMPUTED TOMOGRAPHY (SPECT). These GAMMA CAMERAS consist of a gantry, single or multiple DETECTOR HEADS, and a computer for data acquisition, processing, storage, and display. The DETECTOR HEADS may contain single or multiple scintillation crystals or solid state detectors. No test has been specified to characterize the uniformity of reconstructed images because all methods known so far will mostly reflect the noise of the image.

ČSN EN 62680-1-1 The Battery Charging Working Group is chartered with creating specifications that define limits as well as detection, control and reporting mechanisms to permit devices to draw current in excess of the USB 2.0 specification for charging and/or powering up from dedicated chargers, hosts, hubs and charging downstream ports. These mechanisms are backward compatible with USB 2.0 compliant hosts and peripherals.

ČSN EN ISO 16904 This International Standard specifies the design, minimum safety requirements and inspection and testing procedures for liquefied natural gas (LNG) marine transfer arms intended for use on conventional onshore LNG terminals, handling LNG carriers engaged in international trade. It can provide guidance for offshore and coastal operations. It also covers the minimum requirements for safe LNG transfer between ship and shore. Although the requirements for power/control systems are covered, this International Standard does not include all the details for the design and fabrication of standard parts and fittings associated with transfer arms. This International Standard is supplementary to local or national standards and regulations and is additional to the requirements of ISO 28460. This International Standard needs not be applied to existing facilities.
