ČSN EN 196-2 Tento dokument stanovuje metody pro chemický rozbor cementu. Tento dokument uvádí referenční metody a pro jisté případy alternativní metodu, která může být považována za ekvivalentní. V případě sporu se použije pouze metoda referenční. Alternativní metoda rozboru cementu použitím rentgenfluorescenční spektrometrie (XRF) je popsána pro stanovení SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, K2O, Na2O, TiO2, P2O5, Mn2O3, SrO, Cl a Br. Tato metoda je založena na měření vzorku ve formě vytavené perly a analytické validaci použitím certifikovaných referenčních materiálů a kritérií přesnosti a správnosti. Metoda založená na měření lisovaných tablet nevyžíhaného vzorku může být také použita za předpokladu, že jsou dodržena stejná kritéria. Pro stanovení SO3 je popsána alternativní metoda s využitím optické emisní spektroskopie s indukčně vázaným plazmatem (ICP-OES). Pokud je metoda správně kalibrována podle zavedených postupů a referenčních materiálů, XRF a ICP-OES jsou metody rovnocenné referenční metodě, ale nejsou dosud ověřeny pro prokázání shody nebo pro případy sporů. Metody mohou být použity i pro další prvky, pokud se provedou odpovídající kalibrace. Mohou být použity jakékoliv jiné metody za předpokladu, že byly k prokázání jejich rovnocennosti kalibrovány buď proti referenčním metodám nebo proti mezinárodně uznaným referenčním materiálům. Tento dokument uvádí metody, které se použijí obecně pro cementy, ale které mohou být použity také pro jeho složky a pro jiné materiály, v jejichž normách je na tyto metody odkaz. Normy výrobku určí, které metody mají být použity.

ČSN EN 1793-5 This document specifies a test method for measuring a quantity representative of the intrinsic characteristics of sound reflection from road noise reducing devices, the sound reflection index, and then calculate a single-number rating for sound absorption from it. This document is applicable to: - the determination of the intrinsic characteristics of sound absorption of noise reducing devices to be installed along roads, to be measured either on typical installations alongside roads or on a relevant test specimen section; - the determination of the intrinsic characteristics of sound absorption of road traffic noise reducing devices in actual use under direct sound field conditions; - the comparison of design specifications with actual performance data after the completion of the construction work; - the verification of the long-term performance of road traffic noise reducing devices (with a repeated application of the method). This document does not apply to: - the determination of the intrinsic characteristics of sound absorption of road traffic noise reducing devices to be installed in reverberant conditions, e.g. inside tunnels or deep trenches. Results for the sound reflection index are expressed as a function of frequency, in one-third octave bands between 200 Hz and 5 kHz, for qualification purposes. If it is not possible to get valid measurement results over the whole frequency range indicated, the results are given in a restricted frequency range, and the reasons for the restriction(s) are clearly reported. For indoor measurements, see Annex D.

ČSN EN IEC 61076-2-111 ed. 2 This part of IEC 61076 2 describes 4- to 6-way circular connectors with M12 screw-locking with current ratings 8, 12 or 16 A per contact and voltage ratings of 50 V AC / 60 V DC or 630 V according to their coding, that are typically used for power supply and power applications in industrial premises. These connectors consist of both fixed and free connectors, either rewirable or non-rewirable. Male connectors have round contacts 1,0 mm and 1,5 mm. The different codings provided by this document prevent the mating of differently coded male or female connectors to any other similarly sized interfaces, covered by other standards and the cross-mating between the different codings provided by this document. NOTE 1 - M12 is the dimension of the thread of the screw locking mechanism of these circular connectors. NOTE 2 - Several other IEC standards are available covering additional styles of circular connectors with M12 x 1 screw-locking, see Bibliography.

ČSN EN IEC 63437 This document specifies the essential characteristics of off grid and unreliable grid refrigerating appliances for domestic and similar use or light commercial use, cooled by internal natural or forced air convection. It defines input voltage supply signals for appliances designed for unreliable grid and off grid conditions. An unreliable grid condition can be the result of disturbances on the electricity supply, such as power outages, or issues with power quality, such as voltage spikes and surges, that could cause performance challenges to refrigerating appliances. An off grid supply, in this context, for example is generated by a solar panel or a stand-alone solar home system that is not connected to the power grid. This document simulates the power characteristics in off grid and unreliable grid conditions but does not specify requirements or test procedures to assess performance of generators, solar panels, solar home system or any other system generating a supply signal. The supply signals defined in this document can also be used for evaluation of the performance of other refrigerating appliances such as medical or laboratory appliances, professional storage refrigerators or freezers, refrigerated display cabinets, beverage coolers or ice cream freezers. This document specifies the test methods for measuring the functional performance characteristics and requirements. This document does not apply to refrigerating appliances designed for a good quality and stable electricity grid and refrigerating appliances utilising fuelled absorption cooling technology. This document is applicable to any refrigerating appliance for domestic or light commercial use that has a rated performance to properly operate off grid or under unreliable grid operating conditions resisting power interruptions and supply variations. Off grid and unreliable grid refrigerating appliances are appliances intended to for use with standalone or intermittent or distorted electrical mains. Electrical mains supply is assumed to be alternating current (AC) for unreliable grid or direct current (DC) for off grid. This document is also applicable to hybrid refrigerating appliances. The test procedures primary focus on the performance of the overall refrigerating appliances and not on the specific performance of auxiliary components such as electrical batteries, inverters or rectifiers or any device intended to improve the power quality but external to the appliance itself. In case a refrigerating appliance is supplied with control unit, an electrical battery, a voltage protector, an inverter or a rectifier in the original product packaging, these components are considered as a component of the refrigerating appliance and are connected during testing. The tests defined in this document aim to assess the fundamental design and functional operation of the refrigerating appliance as well as its resilience to given power quality issues.

ČSN EN ISO/IEEE 11073-10421 This document establishes a normative definition of communication between personal telehealth peak flow mo-nitoring devices (agents) and managers (e.g., cell phones, personal computers, personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability. It leverages work done in other ISO/IEEE 11073 standards including existing terminology, information profiles, application profile standards. It specifies the use of specific term codes, formats, and behaviors in telehealth environments restricting optionality in base frameworks in favor of interoperability. This document defines a common core of functionality of a peak-flow monitoring device. The use case is restricted to personal respiratory monitoring and therefore does not include hospital-based spirometry. Continuous and high-acuity monitoring (e.g., for emergency response) are outside the scope of the use case. In the context of personal health devices, a peak flow meter is a device is used to measure the respiratory function of those managing respiratory conditions such as asthma and chronic obstructive pulmonary disease. The ability to identify declining respiratory status prior to the need for acute intervention improves the quality of life for the individual while reducing the overall costs of care. Respiratory status data are collected by a personal respiratory monitoring device and forwarded to a central data repository for review and action by a health care provider. The data are episodic in nature and are forwarded at designated intervals or when the person is symptomatic.

ČSN EN ISO 27799 This document provides information security controls, including implementation guidance, for health organizati-ons. It is based on ISO/IEC 27002:2022 In addition to generic ICT equipment and software used in many other environments, the scope of this document includes software and systems specifically for healthcare, such as electronic health record systems and medical devices incorporating health software. Such medical devices can be programmed or programmable and can contain software, firmware or both. Other digital equipment (such as that for environmental and infection control, building management, and physical security), which can be used in premises where healthcare is provided, is also in scope. This document applies to information in all its aspects, whatever form the information takes (including text and numbers, sound recordings, drawings, images and video), by whatever means it has been acquired or captured, whatever means are used to store it (such as printing or writing on paper or storage electronically), and whatever means are used to transfer or exchange it (orally, by hand, by post, movement of storage media, direct links or networking). This document is for organi-zations of all types and sizes that provide healthcare or are custodians of personal health information for other reasons. The information that they are responsible for can be stored and processed in many possible ways and locations, including on premises or in the cloud, but remains in scope. This document applies to all physical settings where healthcare is intended to be delivered, such as hospitals, clinics and other locations or facilities designated for healthcare purposes such as ambulances and mobile imaging or diagnostic units. It also applies to care provided elsewhere, such as in residential premises. In addition to the range of settings, this document applies to all methods of service provision including remote or virtual healthcare.
