ČSN EN IEC 63047 This international standard specifies the format of binary list-mode data at the output of digital data acquisition devices used for the detection and measurement of radiation. Such data acquisition devices may employ digital signal processors (DSPs) and field-programmable gate arrays (FPGAs) in combination with memory and a communication interface with a computer. This document is applicable to those data acquisition devices which are able to record and present interaction data of radiation in detectors on an event-per-event basis, with data stored in an output file or streamed to a remote computer. Such list-mode data typically contains timestamp and energy information, but may also contain digital signals or properties like rise time or sub-areas of signals computed by the DSP or FPGA from the signal samples. It is not the scope of this document to specify the communication protocol between data acquisition hardware and the instrument drivers. Instead, it specifies a standard format for the presentation of data acquired by one or more acquisition devices, to the user or user application. This document only specifies the binary formatting of data. The formatted data may be sent or stored as specified by other protocols. Also, commands to control data acquisition devices are not included in this document.

ČSN EN ISO 15663 This document specifies requirements for and gives guidance on the application of life cycle costing to create value for the development activities and operations associated with drilling, exploitation, processing and transport of petroleum, petrochemical and natural gas resources. This document covers facilities and associated activities within different business categories (upstream, midstream, downstream and petrochemical). The life cycle costing process as described in this document is applicable when making decisions between competing options that are differentiated by cost and/or economic value. This document is not concerned with decision-making related to the economic performance of individual options or options differentiated by factors other than cost or economic value. Guidance is provided on the management methodology and application of life cycle costing in support of decision-making across life cycle phases. The extent of planning and management depends on the magnitude of the costs involved, the potential value that can be created and the life cycle phase. It also provides the means of identifying cost drivers and provides a cost-control framework for these cost drivers, allowing effective cost control and optimization over the entire life of an asset.

ČSN ETSI EN 303 204 V3.1.1 The present document specifies technical characteristics and methods of measurements for the following types of equipment: - Type 1 equipment: SRDs in data networks: - Type 1a: Terminal nodes - Type 1b: Network nodes - Type 1c: Network access points Type 1a terminal nodes and type 1b network nodes are fixed SRDs, operating up to 500 mW e.r.p. and with adaptive power control, which are intended to operate in association with other SRDs to form data network topologies supporting the intended application. Type 1c network access points are specific fixed SRDs, operating up to 500 mW e.r.p. and with adaptive power control, supporting interconnection of a network of SRDs with an external network or service. These radio equipment types are capable of operating in all or part of the relevant frequency bands given in Table 1. NOTE 1: 874,0 MHz - 874,4 MHz is a harmonised core band according to EC Decision 2018/1538 [i.3]. NOTE 2: The availability of the frequency bands in Table 1 in European Union and CEPT countries can be obtained from the EFIS (http://www.efis.dk/) and is also listed in Appendices 1 and 3 of CEPT/ERC/REC 70 03 [i.2]. NOTE 3: In addition, it should be noted that, in some countries, part or all of the bands in Table 1 may be unavailable, and/or other frequency bands may be available, for networked and/or network based short range devices. See National Radio Interfaces (NRI) as relevant for additional guidance. NOTE 4: On non-harmonized parameters, national administrations may impose certain conditions such as the type of modulation, frequency, channel/frequency separations, maximum transmitter radiated power, duty cycle, installation and operation only by professional users and the inclusion of an automatic transmitter shut-off facility, as a condition for the issue of Individual Rights for use of spectrum or General Authorization, or as a condition for use under "licence exemption" as it is in most cases for Short Range Devices. The present document covers equipment intended for use in a fixed location. The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference. NOTE 5: The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU [i.1] is given in Annex A.
