This standard gives guidance on establishing a decision-making framework for sharing data and information services in smart cities. It covers: a) types of data in smart cities; b) establishing a data sharing culture; c) data value chain – roles and responsibilities; d) purposes for data use; e) assessing data states; f) defining access rights for data; and g) data formats/format of transportation. This standard aims to support the sharing of data and information services within cities. For some cities there will also be a need to establish specific data sharing agreements, particularly where data is being shared by multiple organizations at once. This standard supports a transparent approach to making decisions and creating specific data sharing agreements in order to fully realise the benefits and value of data and information services in a city. Missing data or misinterpretation of data can lead to the wrong actions being taken by city decision-makers. A decision-making framework for sharing data can help ensure that they have the best overall data on which to base decisions. This standard does not cover: a) national security issues; b) good practice for use of data by the citizen; c) existing interoperability agreements between cities; d) defining application programming interfaces (API) networks; or e) any data sharing rules and regulations specific to a particular jurisdiction. It is assumed that a security-minded approach to data sharing is used by cities. NOTE 1 Further details on the areas not covered in this standard, including information on relevant standards publications, are given in Annex A. This standard is for use by decision-makers in smart cities from the public, private and third sectors. It is also of interest to any city organization wishing to share data.

This document specifies the design, minimum safety requirements, and inspection and testing procedures for liquefied hydrogen (LH2) marine transfer arms intended for use at onshore LH2 terminals handling LH2 carriers. It also covers the minimum requirements for safe LH2 transfer between ship and shore. Although the requirements for power/control systems are covered, this document does not include all of the details for the design and fabrication of standard parts and fittings associated with transfer arms. This document is mainly focused on hard pipe type transfer systems; hose type transfer systems are not described in detail in the general description of this document. However, hose type transfer systems can also be considered as reasonable vacuum insulated technology for the design of transfer arms for liquefied hydrogen.

This document specifies a mechanism for exchanging data and messages in the following cases: a) exchange between a traffic management centre and ITS roadside equipment for traffic management; b) exchange between ITS roadside equipment used for traffic management. This document is not applicable to: — communication between traffic management centres and in-vehicle units; — communication between ITS roadside equipment and in-vehicle units; — in-vehicle communication; — in-cabinet communication; — motion video transmission from a camera or recorded media. This document is suitable for use when both of the following conditions apply: 1) The data to be exchanged can be defined as one or more elements that can be retrieved or stored – SNMP can support a wide variety of devices and has adopted the concept of a management information base (MIB), which identifies the configuration, control and monitoring parameters for ITS roadside equipment. This standardized approach is commonly used for network management applications for devices such as routers, switches, bridges and firewalls. It is also used in many regions to control devices such as dynamic message signs. 2) Guaranteed, deterministic, real-time exchange of data is not critical – SNMP operations typically require less than 100 ms, but the underlying network can cause multi-second delays in delivering messages or even lost messages; thus, SNMP is not intended for applications that require reliable sub-second communications. This document can be used for: — intermittent exchange of any defined data (normal SNMP operations allow messages to be structured by combining any group of elements into a retrieval or storage request); — repeated, frequent exchanges of the same message structure (with potentially different values), even on relatively low-bandwidth links; NOTE 1 The dynamic object feature, defined in ISO/TS 26048-1, can be used to eliminate a considerable amount of overhead that is normally associated with SNMP communications to make it more suitable for low-bandwidth links. — allowing ITS roadside equipment to issue exception reports when special conditions arise. NOTE 2 Exception reporting uses SNMP notifications in combination with the notification management features defined in ISO/TS 26048-1.

This document gives guidelines and requirements for the procedures to be followed when carrying out vibration diagnostics of 2‑ and 4‑pole electrical generators of cylindrical pole design with fluid-film bearings.

The requirements of this document should be considered together with those in ISO 13373-4.

This document specifies general requirements and gives guidance on microbiological examinations. It is applicable to: — the implementation of specific horizontal or vertical International Standards developed by ISO/TC 34/SC 9 or ISO/TC 34/SC 5 for detection or enumeration of microorganisms, named hereafter “specific standards”; — good laboratory practices for microbiology laboratories testing samples from the food chain; — guidance for microbiological laboratories testing samples from the food chain on the technical requirements for conforming to ISO/IEC 17025. The requirements of this general standard supersede corresponding ones in existing specific standards. Additional instructions for examinations using the polymerase chain reaction (PCR) are specified in ISO 22174. This document is applicable to examinations for bacteria, yeasts and moulds and can be used, if supplemented with specific guidance, for parasites and viruses. It does not apply to examinations for toxins or other metabolites (e.g. amines) from microorganisms. This document is applicable to microbiology of the food chain, from primary production stage to food and animal feed products, including the premises where the food or feed production and handling takes place. It is also applicable to the microbiological examination of water where water is used in food production or is regarded as a food in national legislation.

This document specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts under standardized fire conditions. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This document is intended to be used in conjunction with ISO 834-1. This document is not applicable to: a) ducts whose fire resistance depends on the fire resistance performance of a ceiling; b) ducts containing fire dampers at points where they pass through fire separations; c) doors of inspection openings, unless included in the duct to be tested; d) two-sided or three-sided ducts; e) the fixing of suspension devices to floors or walls; f) kitchen extract ducts (see ISO 6944-2). NOTE Annex A provides general guidance and gives background information.

Each type is divided into two classes having either an oil resistant or non-oil resistant cover.
NOTE Information on the frequency of testing of hose assemblies in use and storage is given in Annex A and Annex B.
