This document contains the terms and definitions of general concepts to establish a vocabulary applicable to buildings and civil engineering works.

It comprises:

a) fundamental concepts, which can be the starting point for other, more specific, definitions;

b) more specific concepts, used in several areas of construction and frequently used in standards, regulations and contracts.

This European Standard specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants. The term "refrigerating system" used in this European Standard includes heat pumps. This part of EN 378 specifies the classification and selection criteria applicable to refrigerating systems. These classification and selection criteria are used in parts 2, 3 and 4. This standard applies: a) to refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard e.g. ISO 13043; b) to secondary cooling or heating systems; c) to the location of the refrigerating systems; d) to replaced parts and added components after adoption of this standard if they are not identical in function and in the capacity; Systems using refrigerants other than those listed in Annex E of this European Standard are not covered by this standard. Annex C specifies how to determine the amount of refrigerant permitted in a given space, which when exceeded, requires additional protective measures to reduce the risk. Annex E specifies criteria for safety and environmental considerations of different refrigerants used in refrigeration and air conditioning. This standard is not applicable to refrigerating systems and heat pumps which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication. This standard is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site. This standard also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of pa ...

This European Standard specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants. The term "refrigerating system" used in this European Standard includes heat pumps. This Part 2 of this Standard is applicable to the design, construction and installation of refrigerating systems including piping, components and materials. It includes ancillary equipment not covered in FprEN 378-1:2016, FprEN 378-3:2016 or FprEN 378-4:2016 which is directly associated with these systems. It also specifies requirements for testing, commissioning, marking and documentation. Requirements for secondary heat transfer circuits are excluded except for any protection requirements associated with the refrigerating system. Ancillary equipment includes, for example, fans, fan motors, electrical motors and transmission assemblies for open compressor systems. This standard applies: a) to refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard, e.g. ISO 13043; b) to secondary cooling or heating systems; c) to the location of the refrigerating systems; d) to replaced parts and added components after adoption of this standard if they are not identical in function and in the capacity. Systems using refrigerants other than those listed in Annex E of FprEN-378 1:2016 are not covered by this standard. This standard does not apply to goods in storage. This standard is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication. This standard is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary sy ...

This document contains the terms and definitions of the concepts used in ISO/TC 46/SC 11 products related to records management. It does not limit the definition of new terms in ISO/TC 46/SC 11 products

This document specifies the general aspects of polyethylene (PE) piping systems in the field of the supply of gaseous fuels.

It also specifies the test parameters for the test methods referred to in this document.

In conjunction with Parts 2 to 5 of EN 1555, this document is applicable to PE pipes, fittings, and valves, their joints and to joints with components of other materials intended to be used under the following conditions:

a) a maximum operating pressure, MOP, up to and including 10 bar 1;

b) an operating temperature of 20 °C as reference temperature.

NOTE 1 For other operating temperatures, derating coefficients can be used, see prEN 1555-5:2019 [1].

EN 1555 (all parts) covers a. range of maximum operating pressures and gives requirements concerning colours.

NOTE 2 It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

This document provides fundamental terminology for blockchain and distributed ledger technologies.

This document provides terminology and commercial specifications for paver-finishers used in road construction and maintenance processes for the placement and pre-compaction of paving materials. It covers the machine and its components and establishes parameters for technical characteristics for both.

This document does not cover terms and commercial specifications for road wideners which can perform similarly to a paver-finisher under certain conditions.

ISO 4306 as a whole establishes a vocabulary of the most commonly used terms in the field of cranes.

This part of ISO 4306 defines the terms related to jib type cranes. Mobile cranes, tower cranes, railway cranes, and offshore cranes are excluded.

See Annex A for the diagram regarding types of jib cranes.

This document provides guidance based on ISO/IEC 27002:2013 applied to process control systems used by the energy utility industry for controlling and monitoring the production or generation, transmission, storage and distribution of electric power, gas, oil and heat, and for the control of associated supporting processes. This includes in particular the following:

— central and distributed process control, monitoring and automation technology as well as information systems used for their operation, such as programming and parameterization devices;

— digital controllers and automation components such as control and field devices or Programmable Logic Controllers (PLCs), including digital sensor and actuator elements;

— all further supporting information systems used in the process control domain, e.g. for supplementary data visualization tasks and for controlling, monitoring, data archiving, historian logging, reporting and documentation purposes;

— communication technology used in the process control domain, e.g. networks, telemetry, telecontrol applications and remote control technology;

— Advanced Metering Infrastructure (AMI) components, e.g. smart meters;

— measurement devices, e.g. for emission values;

— digital protection and safety systems, e.g. protection relays, safety PLCs, emergency governor mechanisms;

— energy management systems, e.g. of Distributed Energy Resources (DER), electric charging infrastructures, in private households, residential buildings or industrial customer installations;

— distributed components of smart grid environments, e.g. in energy grids, in private households, residential buildings or industrial customer installations;

— all software, firmware and applications installed on above-mentioned systems, e.g. DMS (Distribution Management System) applications or OMS (Outage Management System);

— any premises housing the above-mentioned equipment and systems;

— remote maintenance systems for above-mentioned systems.

This document does not apply to the process control domain of nuclear facilities. This domain is covered by IEC 62645.

This document also includes a requirement to adapt the risk assessment and treatment processes described in ISO/IEC 27001:2013 to the energy utility industry-sector–specific guidance provided in this document.
