ČSN EN 17235 This document specifies assessment of characteristics for anchor devices and safety hooks intended to be used with personal fall protection systems to prevent persons from falling and arrest falls, both permanently fixed on or into buildings and civil engineering works. The safety hooks covered under this standard are also intended to for the attachment of mobile roof ladders or work platforms and have an opening of not less than 80 mm and not more than 150 mm, see Figure 2. The height h of the hook is at least 120 mm. NOTE - The personal fall protection systems are used according to EN 363:2018. This standard also covers the fastening kits used to secure the anchor devices or safety hooks on or into the load bearing structure. It specifies essential dimensions, materials and criteria to assess the performance of representative load bearing structures. This standard describes the methods and criteria to assess the performance and durability of the following anchor kits: - Kit A (Anchor kit incorporating a single anchor device); - Kit B (Anchor kit incorporating a safety hook); - Kit C (Anchor kit incorporating a horizontal wire anchor line); - Kit D (Anchor kit incorporating a horizontal rail anchor line). The kits described in this standard consist usually of several components. They are intended to be evaluated as a kit in its entirety. This standard is not applicable to: - Temporary anchor devices according to EN 795:2012; - Facilities for roof access according to EN 516:2006; - Permanently fixed ladders on roofs according to EN 12951:2004. - Permanent anchor devices and safety hooks fixed with nails.

ČSN P ISO/TS 5667-25 Účelem tohoto dokumentu je popsat plány zkoušek a různé metodiky těchto plánů pro stanovení a ověření přijatelné stability látek ve vzorku za specifikovaných podmínek konzervace (teplota, matrice, přístup světla, přídavek konzervačního činidla, pokud je vhodné, druh konzervace atd.) před začátkem analytických postupů (chemických a fyzikálně-chemických analýz). Do tohoto dokumentu nejsou zahnuty biologické a mikrobiologické metody. Pro provedení zkoušky stability a zavedení plánů zkoušek je nezbytné, aby analytická metoda již měla charakterizovanou výkonnost (opakovatelnost, preciznost, pravdivost, přesnost a nejistotu).

ČSN EN 353-2 This document specifies requirements, test methods, marking, manufacturer's instructions and information and packaging for guided type fall arresters including a flexible anchor line forming a single product. This anchor line is attached to an upper anchor point for vertical and inclined applications; for horizontal applications, the anchor point can be located at the user's foot level. Guided type fall arresters including a flexible anchor line conforming to this document are components of one of the fall arrest systems covered by EN 363:2018. Other types of fall arresters are specified in EN 353-1:2014+A1:2017 or EN 360:2023.

ČSN ETSI EN 303 645 V3.1.3 The present document specifies high-level security and data protection provisions for consumer IoT devices that are connected to network infrastructure (such as the Internet or home network) and their interactions with associated services. A non-exhaustive list of examples of consumer IoT devices includes: - connected children's toys and baby monitors; -connected smoke detectors, door locks and window sensors; - IoT gateways, base stations and hubs to which multiple devices connect; - smart cameras, smart speakers and smart Televisions together with their remote controls; - wearable health trackers; - connected home automation and alarm systems, especially their gateways and hubs; - connected appliances, such as washing machines and fridges; and - smart home assistants. Moreover, the present document addresses security considerations specific to constraints in device resources. EXAMPLE - Typical device resources that might constrain the security capabilities are energy supply, communication bandwidth, processing power or (non-)volatile memory capacity. The present document provides basic guidance through examples and explanatory text for organizations involved in the development and manufacturing of consumer IoT on how to implement those provisions. Table B.1 provides a schema for the reader to give information about the implementation of the provisions. Devices that are not consumer IoT devices, for example those that are primarily intended to be used in manufacturing, healthcare or other industrial applications, are not in scope of the present document. The present document has been developed primarily to help protect consumers, however, other users of consumer IoT equally benefit from the implementation of the provisions set out here. Annex A (informative) of the present document has been included to provide context to clauses 4, 5 and 6 (normative). Annex A contains examples of device and reference architectures and an example model of device states including data storage for each state.

ČSN ETSI EN 300 132-2 V2.8.1 The present document contains requirements and measurements methods for the physical interface "A" that is situated between the power supply system(s) and the power consuming ICT equipment. The nominal voltage at power interface "A" of ICT equipment defined in the present document is DC voltage -48 V. The DC power can be supplied by a DC output power system (e.g. based on AC rectifiers on grid or DC/DC converters on solar system, fuel cell, DC engine or fuel cell generator) and also directly supplied by a battery backup in this DC power system. The purpose of the present document is to be able to use a power supply system with the same characteristics for all ICT equipment defined in the area of application: - to facilitate inter working of different types of load units; - to facilitate the standardization of ICT equipment; - to facilitate the installation, operation and maintenance in the same network of ICT equipment and systems from different origins. The present document aims at providing electrical compatibility between the power supply equipment and the power consuming ICT equipment, between different system blocks and loads connected to the same power supply feeding the interface "A" (e.g. control/monitoring, cooling system, etc.). The requirements are defined for: - the power supply input of any type of ICT equipment installed at telecommunication centres that are connected to interface "A" powered by DC; - any type of ICT equipment, installed in access networks and customers' premises, the DC interface "A" of which is also used by equipment requiring a DC supply source; - any type of ICT equipment powered by DC, used in the fixed and mobile networks installed in different locations such as buildings, shelters, street cabinets, outdoor installations. Disturbances on the power supply interface "A" relating to the continuous wave phenomena below 20 kHz are covered within the present document. The present document does not cover safety requirements, they are covered by relevant safety standards. The present document does not cover EMC requirements, they are covered by relevant EMC standards. NOTE - Annex B gives guidance on -60 VDC supply systems.
