This document establishes the terms and definitions, used in the field of natural gas, natural gas substitutes, mixtures of natural gas with gaseous fuels (such as unconventional and renewable gases) and wet gas.

ISO 18369-1:2017 identifies and defines the terms applicable to the physical, chemical and optical properties of contact lenses, their manufacture and uses. It provides a vocabulary of terms and, when appropriate, the international symbol and abbreviation associated with a specific term. This document also defines the terms relating to contact lens care products. It also incorporates the classifications of contact lens materials and gives recommendations for the labelling of the specifications of contact lenses.

This document defines terms used in dental product standards. This document aims to facilitate the standard development process and the comprehension of standards, and to improve communication with the FDI World Dental Federation, the World Health Organization and other organizations interested in standardization.

This International Standard defines the terminology that is used in acoustic emission testing and forms a common basis for standards and general use.

In 2006, the United States developed ISO 16792-2006 Technical product documentation-Digital product definition data practices adopted from the ASME Y14.41-2003 Digital product definition data practices. It was then revised and improved continuously. This standard is the basic standard for the three-dimensional digital design, which specifies how to add attributes, annotations, and other information to the design model to achieve a digital definition of the product. However, we believe that the way of modelling as well as the sequence and general requirements of modelling are of equal importance for reflecting design intent properly. Therefore, we propose a new international standard work item proposal to stipulate the construction, application and management requirements for the design model in the three-dimensional digital design process of mechanical products, which expressed as follows: 1) General requirements, including terms and definitions related to three-dimensional modelling, classification and composition of three-dimensional digital model, the naming principle of three-dimensional model files, definition and classification of geometric modelling features; 2) General process and requirements for part modelling, including common parts and specific parts, such as polymorphic parts, flexible parts and others; 3) General process and requirements for assembly modelling, including assembly level definition, assembly constraint definition, management of assembly structure tree, assembly model packaging and other requirements; 4) Model application management requirements, including basic requirements for model checking, model release, model data management, and the technical status management.

Denna standard omfattar termer inom blankett- och dokumentteknik och innehåller ett avsnitt med alfabetiskt ordnade termer och definitioner och ett avsnitt där termerna har grupperats efter samband och släktskap.

Standarden syftar till enhetlig terminologi inom blankett- och dokumenttekniken och riktar sig i första hand till blankettkonstruktörer, tillverkare och leverantörer av blanketter.

This document specifies the preparation and reproduction of design parts lists. This document defines the basic principles and structure of design parts lists. This document is applicable to all design parts lists for railway applications.

This document 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 document 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 5. This document applies to: a) refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard e.g. [7] b) secondary cooling or heating systems; c) the location of the refrigerating systems; d) replaced parts and added components after adoption of this document if they are not identical in function and in the capacity. Systems using refrigerants other than those listed in Part 5 of this standard are not covered by this document. Clause 7 specifies how to determine the refrigerant quantity safety limit in a given space, which, when exceeded, requires additional protective measures to reduce the risk. This document 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 document 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 document also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of Parts 1, 2, 3 and 5 of the standard is expected to be assessed. Product family standards dealing with the safety of refrigerating systems take precedence over horizontal and generic standards covering the same subject.

This document 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 document 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 EN 378 1, EN 378 3 or prEN 378 5 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 document applies to: a) refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard, e.g. ISO 13043:2011 [1]; b) secondary cooling or heating systems; c) the location of the refrigerating systems; d) replaced parts and added components after adoption of this document if they are not identical in function and in the capacity. Systems using refrigerants other than those listed in prEN 378 5 are not covered by this document. This document does not apply to goods in storage. This document 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 document 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 document also applies in the case of the conversion of a system to another refrigerant type. Designation, classification, and selected properties of the refrigerant such as: — refrigerant number, e.g. R717; — safety classes A1, A2L, A2, A3, B1, B2L, B2, B3; — lower flammability limits (LFL) are specified in prEN 378 5.
