ČSN EN 16603-60-20 This Standard specifies star sensor performances as part of a space project. The Standard covers all aspects of performances, including nomenclature, definitions, and performance requirements for the performance specification of star sensors. The Standard focuses on: - performance specifications (including the impact of temperature, radiation and straylight environments); - robustness (ability to maintain functionalities under non nominal environmental conditions). Other specification types, for example mass and power, housekeeping data and data structures, are outside the scope of this Standard. This Standard also proposes a standard core of functional interfaces defined by unit suppliers and avionics primes in the context of Space AVionics Open Interface aRchitecture (SAVOIR) initiative. When viewed from the perspective of a specific project context, the requirements defined in this Standard should be tailored to match the genuine requirements of a particular profile and circumstances of a project. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.

ČSN EN 17173 This document contains terms and definitions for CBRNE (chemical, biological, radiological, nuclear, explosive) applications. Common understanding and communication is important in the implementation of an effective CBRNE response and this communication will be most effective if there is common understanding of the terms used. Many of the terms and definitions listed here have been widely used for many years, while others are the result of cross-cutting experience of areas of CBRNE. The gradual evolution of our understanding of CBRNE and response measures means that CBRNE terminology will continue to develop. This document is dedicated to first responders, administrative staff, industry representatives and researchers.

ČSN EN 16803-2 Like the other documents of the whole series, this document deals with the use of GNSS-based positioning terminals (GBPT) in road Intelligent Transport Systems (ITS). GNSS-based positioning means that the system providing position data, more precisely Position, Velocity and Time (PVT) data, comprises at least a GNSS receiver and, potentially, for performance improvement, other additional sensor data or sources of information that can be hybridized with GNSS data. This new document proposes testing procedures, based on the replay of data recorded during field tests, to assess the basic performances of any GBPT for a given use case described by an operational scenario. These tests address the basic performance features Availability, Continuity, Accuracy and Integrity of the PVT information, but also the Time-To-First-Fix (TTFF) performance feature, as they are described in EN 16803-1, considering that there is no particular security attack affecting the SIS during the operation. This document does not cover the assessment tests of the timing performances other than TTFF, which do not need field data and can preferably be executed in the lab with current instruments. "Record and Replay" (R&R) tests consist in replaying in a laboratory environment GNSS SIS data, and potentially additional sensor data, recorded in specific operational conditions thanks to a specific test vehicle. The data set comprising GNSS SIS data and potential sensor data resulting from these field tests, together with the corresponding metadata description file, is called a "test scenario". A data set is composed of several data files. This EN 16803-2 addresses the "Replay" part of the test scenario data set. It does not address the "Record" part, although it describes as informative information the whole R&R process. This "Record" part will be covered by EN 16803-4 under preparation. Although the EN 16803 series concerns the GNSS-based positioning terminals and not only the GNSS receivers, the present release of this document addresses only the replay process of GNSS only terminals. The reason is that the process of replaying in the lab additional sensor data, especially when these sensors are capturing the vehicle's motion, is generally very complex and not mature enough to be standardized today. It would need open standardized interfaces in the GBPT as well as standardized sensor error models and is not ready to be standardized. But, the procedure described in the present EN has been designed to be extended to GBPT hybridizing GNSS and vehicle sensors in the future. This EN 16803-2 does not address R&R tests when specific radio frequency signals simulating security attacks are added to the SIS. This case is specifically the topic of EN 16803-3. Once standardized assessment tests procedures have been established, it is possible to set minimum performance requirements for various intelligent transport applications but it makes sense to separate the assessment tests issue from minimum performance requirements, because the same test procedure may be applicable to many applications, but the minimum performance requirements typically vary from one application to another. So, this document does not set minimum performance requirements for any application.

ČSN EN IEC 61400-27-1 ed. 2 This part of IEC 61400 defines standard electrical simulation models for wind turbines and wind power plants. The specified models are time domain positive sequence simulation models, intended to be used in power system and grid stability analyses. The models are applicable for dynamic simulations of short term stability in power systems. This document defines the generic terms and parameters for the electrical simulation models. This document specifies electrical simulation models for the generic wind power plant topologies / configurations currently on the market. The wind power plant models include wind turbines, wind power plant control and auxiliary equipment. The wind power plant models are described in a modular way which can be applied for future wind power plant concepts and with different wind turbine concepts. This document specifies electrical simulation models for the generic wind turbine topologies/concepts/configurations currently on the market. The purpose of the models is to specify the electrical characteristics of a wind turbine at the wind turbine terminals. The wind turbine models are described in a modular way which can be applied for future wind turbine concepts. The specified wind turbine models can either be used in wind power plant models or to represent wind turbines without wind power plant relationships. The electrical simulation models specified in IEC 61400-27-1 are independent of any software simulation tool.

ČSN EN ISO 35104 This document establishes the principles, specifies the requirements and provides guidance for ice management (IM) in arctic and cold regions, from the point of view of planning, engineering, implementation and documentation. Reference to arctic and cold regions in this document is deemed to include both the Arctic and other regions characterized by low ambient temperatures, sea ice, icebergs and icing conditions. These regions are often remote and lacking in marine and communications infrastructure. Ice management to support the following in-ice activities and infrastructures are covered by this document: - floating moored and/or dynamically positioned drilling vessels, coring vessels, production facilities and work-over vessels; - construction and installation (includes trenching, dredging, pipe laying); - tanker loading and other offloading operations; - protecting subsea structures and equipment; - seismic operations; - oil spill response; - bottom founded structures (fixed platforms and movable structures, including jack-ups). This document also applies to mobilization, demobilization and construction support services, because these can be affected by ice conditions. In view of the wide range of possible offshore operations in arctic and cold regions, this document provides guidelines, but does not present typical ice management plans for field operations. This document does not provide requirements, recommendations or guidance pertaining to the design of structures, systems and components used in ice management, beyond the principles given. This document does not provide specific formulations for ice loads, which are covered by ISO 19906. This document is not applicable to coastal port operations and to commercial trading vessels conducting transit or convoy operations.

ČSN EN 16524 This document describes a methodology for reducing the overall environmental impact through product design and development that is tailored to mechanical products as defined in 3.1. This methodology is particularly well suited to the redesign of an existing product; it can also be applied for the design of a new product provided the necessary assumptions regarding a (virtual) reference product are taken. It addresses companies which have decided to integrate an ecodesign approach to optimize environmental impacts within the product life cycle, in relation to the other product aspects, such as functionality, quality, costs, etc. It also helps to meet some requirements of EN ISO 14001:2015 on the integration of environmental aspects in the design of products. NOTE 1 - This document targets persons who are directly involved in the design and development of mechanical products, as well as managers responsible for defining corporate policies, and decision-makers. The proposed methodology is intended to kick-start ecodesign initiatives within companies as part of a continuous improvement approach. This document also includes a template that companies can use as part of the communication on their environmental approach. This document is neither intended nor suitable to compare products (even similar) of different suppliers. This document is neither intended nor suitable for product certification purposes. NOTE 2 - An example for the implementation of the methodology is given in Annex D; the background of the algorithm used for this methodology is explained in Annex E.
