ČSN EN IEC 62351-7 ed. 2 This part of IEC 62351 defines network and system management (NSM) data object models that are specific to power system operations. These NSM data objects will be used to monitor the health of networks and systems, to detect possible security intrusions, and to manage the performance and reliability of the information infrastructure. The goal is to define a set of abstract objects that will allow the remote monitoring of the health and condition of IEDs (Intelligent Electronic Devices), RTUs (Remote Terminal Units), DERs (Distributed Energy Resources) systems and other systems that are important to power system operations. Power systems operations are increasingly reliant on information infrastructures, including communication networks, IEDs, and self-defining communication protocols. Therefore, management of the information infrastructure has become crucial to providing the necessary high levels of security and reliability in power system operations. The telecommunication infrastructure that is in use for the transport of telecontrol and automation protocols is already subject to health and condition monitoring control, using the concepts developed in the IETF Simple Network Management Protocol (SNMP) standards for network management. However, power system specific devices (like teleprotection, telecontrol, substation automation, synchrophasors, inverters and protections) need instead a specific solution for monitoring their health. The NSM objects provide monitoring data for IEC protocols used for power systems (IEC 61850, IEC 60870-5-104) and device specific environmental and security status. As a derivative of IEC 60870-5-104, IEEE 1815 DNP3 is also included in the list of monitored protocols. The NSM data objects use the naming conventions developed for IEC 61850, expanded to address NSM issues. For the sake of generality these data objects, and the data types of which they are comprised, are defined as abstract models of data objects. In addition to the abstract model, in order to allow the integration of the monitoring of power system devices within the NSM environment in this part of IEC 62351, a mapping of objects to the SNMP protocol of Management Information Base (MIBs) is provided. The objects that are already covered by existing MIBs are not defined here but are expected to be compliant with existing MIB standards. For example protocols including EST, SCEP, RADIUS, LDAP, GDOI are not in scope.

ČSN CLC IEC/TS 62271-320 This part of IEC 62271 provides guidance to suppliers, manufacturers, users, and waste operators of high-voltage switchgear and controlgear as well as their assemblies having a rated voltage above 1 kV AC and 1,5 kV DC, together with their associated auxiliary equipment, on environmentally conscious design, and on assessing environmental impacts when used in systems. This document also gives guidance on effective communication of environmental information throughout the entire life cycle. This document provides guidance on the process and general aspects to select UN sustainable development goals (UN sustainable development goals (SDG)), especially those dealing with health and environmental impacts and their assessments.

ČSN EN IEC 60115-8 ed. 2 This part of IEC 60115 is applicable to fixed surface mount resistors for use in electronic equipment. These resistors are typically described according to types (different geometric shapes) and styles (different dimensions) and product technology. These resistors have metallized terminations and are primarily intended to be mounted directly onto a circuit board. The object of this document is to specify preferred ratings and characteristics and to select from IEC 60115-1, the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of resistor.

ČSN EN IEC 60115-4 This part of IEC 60115 relates to resistors having a rated dissipation typically greater than 1 W up to and including 1 000 W for use in electronic equipment. This document is applicable to fixed power resistors with a maximum surface temperature (MET) higher than the preferred upper category temperature (UCT) of 200 °C. NOTE - Heat sink resistors, i.e. resistors which in their operation depend on being mounted on a dedicated heat sink, owing to their special temperature conditions, are covered by a special sectional specification (under consideration at the time of publication). These resistors are typically described according to types (different geometric shapes) and styles (different dimensions), and product technology. The resistive element of these resistors is typically - protected by a conformal lacquer coating, or - cement coating, or - vitreous enamel, or - a ceramic body, or - any other housing, which is to be described in the relevant specification. The electrical connection of these resistors is typically achieved by means of - axial leads for through hole assembly (THT), or - vertical or radial leads or punched terminals, or - ferrules or lugs for chassis mount, or - push on terminals, or - screw terminals, or - any other termination, which is to be described in the relevant specification. In special cases, a heat sink can be applicable but not mandatory. The object of this document is to define preferred ratings and characteristics and to select from IEC 60115-1 the appropriate quality assessment procedures, tests and measuring methods and to give general performance requirements for this type of resistor. NOTE - SMD resistors are covered by IEC 60115-8, regardless of their dissipation.

ČSN EN 15978 specifies the calculation method, based on Life Cycle Assessment (LCA) and other quantified environmental information, to assess the environmental performance of a building and its site, during whole life cycle, based on a building life cycle model. It also establishes a system for the reporting and communication of the outcome of the assessment. The document gives: - the description of the object of assessment based on the functional equivalent; - the system boundary that applies at the building level; - calculation rules and procedure to be used to compile and assess the life cycle inventory and life cycle environmental impacts of buildings; - the list of indicators and procedures for the calculation of these indicators; - demand for information concerning building generated energy reporting; - the requirements for the data necessary for the calculation; - provides recommendations on how to assess aspects at the local environment level; and - the requirements for presentation of the results in reporting and communication. The approach to the assessment covers all stages of the building life cycle and is based on data obtained from Environmental Product Declarations (EPD) and their "information modules" (EN 15804:2012+A2:2019), generic data according to EN 15941 and other data and information necessary and relevant for carrying out the assessment. The assessment includes all building related construction products, processes and services, used over the life cycle of the building. The document is applicable to new, existing buildings and buildings undergoing refurbishment or any other kind of activity to extend its service life. Environmental impacts and aspects that are not related to the building are outside the scope of this standard. Methodologies for and approaches to the interpretation and the making of value judgments of the results of the assessment are outside the scope of this document. The document also provides the methodological basis and assessment rules to support the achievement of environment related macro-objectives in Europe and instruments such as the European reporting framework Level(s). NOTE - More information on the European reporting framework Level(s)can be found at Level(s) (europa.eu). Informative Annexes B and C provide non-LCA information covering environmental aspects at the local environment level and additional information on end-of-life scenarios.
