ČSN EN IEC 61158-6-24 ed. 2 The Fieldbus Application Layer (FAL) provides user programs with a means to access the fieldbus communication environment. In this respect, the FAL can be viewed as a "window between corresponding application programs". This part of IEC 61158 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 24 fieldbus. The term "time-critical" is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life.

ČSN EN IEC 61400-21-2 This part of IEC 61400 defines and specifies the quantities that are determined to characterize the electrical characteristics of grid-connected power plants (PPs). This document defines the measurement and test procedures for quantifying the electrical characteristics as basis for the verification of compliance of PPs, including: - power quality aspects, - steady state operation, - dynamic response (undervoltage and overvoltage fault ride-through), - disconnection from grid (grid protection), - control performance. This document defines a uniform functionality test and measurement procedure for the power plant controller (PPC), as a basis for the unit test of the power plant controller. This document defines the procedures for assessing compliance with electrical connection requirements, including the aggregation methods for power quality aspects such as voltage variations, flicker, harmonics and interharmonics. This document defines the procedures for measurement and fault recording, for example for the verification of power plant electrical simulation models in relation to undervoltage and overvoltage ride-through events. These measurement procedures are valid for power plants, including the power plant controller and other connected equipment, necessary for the operation of the power plant. The measurement procedures are valid for any size of power plant connected to the point of connection (POC) at one connection point. The procedures for assessing and verifying the compliance with grid connection requirements are valid for power plants in power systems with fixed frequency and a sufficient short-circuit power.

ČSN EN ISO 19156 This document defines a conceptual schema for observations, for features involved in the observation process, and for features involved in sampling when making observations. These provide models for the exchange of information describing observation acts and their results, both within and between different scientific and technical communities. Observations commonly involve sampling of an ultimate feature-of-interest. This document defines a common set of sample types according to their spatial, material (for ex situ observations) or statistical nature. The schema includes relationships between sample features (sub-sampling, derived samples). This document concerns only externally visible interfaces and places no restriction on the underlying implementations other than what is needed to satisfy the interface specifications in the actual situation.

ČSN EN IEC 62351-9 ed. 2 This part of IEC 62351 specifies cryptographic key management, primarily focused on the management of long-term keys, which are most often asymmetric key pairs, such as public-key certificates and corresponding private keys. As certificates build the base this document builds a foundation for many IEC 62351 services (see also Annex A). Symmetric key management is also considered but only with respect to session keys for group-based communication as applied in IEC 62351-6. The objective of this document is to define requirements and technologies to achieve interoperability of key management by specifying or limiting key management options to be used. This document assumes that an organization (or group of organizations) has defined a security policy to select the type of keys and cryptographic algorithms that will be utilized, which may have to align with other standards or regulatory requirements. This document therefore specifies only the management techniques for these selected key and cryptography infrastructures. This document assumes that the reader has a basic understanding of cryptography and key management principles. The requirements for the management of pairwise symmetric (session) keys in the context of communication protocols is specified in the parts of IEC 62351 utilizing or specifying pairwise communication such as: - IEC 62351-3 for TLS by profiling the TLS options - IEC 62351-4 for the application layer end-to-end security - IEC TS 62351-5 for the application layer security mechanism for IEC 60870-5-101/104 and IEEE 1815 (DNP3) The requirements for the management of symmetric group keys in the context of power system communication protocols is specified in IEC 62351-6 for utilizing group security to protect GOOSE and SV communication. IEC 62351-9 utilizes GDOI as already IETF specified group-based key management protocol to manage the group security parameter and enhances this protocol to carry the security parameter for GOOSE, SV, and PTP. This document also defines security events for specific conditions which could identify issues which might require error handling. However, the actions of the organisation in response to these error conditions are beyond the scope of this document and are expected to be defined by the organizations security policy. In the future, as public-key cryptography becomes endangered by the evolution of quantum computers, this document will also consider post-quantum cryptography to a certain extent. Note that at this time being no specific measures are provided.

ČSN EN 14363+A2 Dokument se zabývá čtyřmi aspekty. Z hlediska vozidel - posuzování jízdních vlastností se v zásadě provádí pro všechna železniční vozidla. Tento dokument obsahuje schvalovací kritéria pro všechny typy vozidel se jmenovitými statickými svislými nápravovými silami do 225 kN (na nejvíce zatíženém dvojkolí vozidla ve stanoveném posuzovaném stavu ložení). Navíc jsou definována schvalovací kritéria pro nákladní vozidla se jmenovitými statickými svislými nápravovými silami do 250 kN. Schvalovací kritéria uvedená v tomto dokumentu platí pro vozidla, konstruovaná pro provoz na normálněrozchodných tratích. Z hlediska infrastruktury - ve schvalovacím procesu je definován rozsah poloměrů oblouků, pro který se vozidlo posuzuje. Vozidlo schválené podle požadavků této normy se může provozovat na všech normálněrozchodných tratích podle EN 13803-1 a EN 13803-2. Dokument rovněž dává návod, jak zacházet s kvalitou geometrie koleje v souvislosti s posuzováním. Z hlediska podmínek rozhraní kolo-kolejnice - dokument obsahuje požadavky ohledně nutného rozsahu ekvivalentní konicity, kterou je třeba v rámci posuzování zahrnout do vytčených zkušebních podmínek. V některých národních systémech, buď částečně, nebo v celé síti, jsou ekvivalentní konicity významně vyšší než jsou vytčené zkušební podmínky tohoto dokumentu. Tyto případy nejsou předmětem tohoto dokumentu. Nicméně metodika pro prokazování stability jízdy, definovaná v tomto dokumentu, se může použít i pro vyšší ekvivalentní konicity. Z hlediska provozních podmínek vyžaduje tento dokument stanovení kombinace přípustné rychlosti a přípustného nedostatku převýšení a rovněž stavů ložení pro každý typ vozidla.
