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 specifies a method for the determination of the mass concentration of particulate arsenic and arsenic compounds in workplace air sampled on a filter (e. g. 37 mm cellulose nitrate filter), digested with acid or an acid mixture and analysed quantitively by using electrothermal atomic absorption spectrometry (ET-AAS). The method is not suitable for determination of arsenic in the form of metal arsenides, which decompose in the presence of water or acid, or for arsenic trioxide vapour. Many different types of sampling apparatus are used to collect respirable or inhalable dust, according to the occupational hygiene convention. This document is designed to accommodate the variety of samplers and collection substrates available to analysts. This document is intended to be used in conjunction with ISO 21832 which promotes best practices for these analyses. The method is applicable to the determination of masses of approximately 0,2 µg to 2 μg of arsenic per sample, for analysis of test solutions prepared using sample solution aliquots in the recommended range (see 10.1.3 and 10.1.4.1). The concentration range for arsenic in air, for which this procedure is applicable, is determined in part by the sampling procedure selected by the user. The method is applicable to personal and stationary air sampling. A number of transition metals can interfere with the determination of arsenic by electrothermal atomic absorption spectrometry (see 11.3).

This document specifies the applicable requirements related to the design and the operation of confinement and ventilation systems for fusion facilities for tritium fuels and tritium fuel handling facilities specific for fusion applications for peaceful purposes using high tritium inventories, as well as for their specialized buildings such as hot cells, examination laboratories, emergency management centres, radioactive waste treatment and storage facilities. In most countries, a tritium quantity is declared as high for tritium inventories higher than a range of 10 g to 100 g. In the tritium fusion facilities in the scope of this document, the tritium inventory is deemed to be higher than this range for the whole site. This document applies especially to confinement and ventilation systems that ensure the safety function of nuclear facilities involved in nuclear fusion with the goal to protect the workers, the public and the environment from the dissemination of radioactive contamination originating from the operation of these installations, and in particular from airborne tritium contamination with adequate confinement systems. The types of confinement systems for other facilities are covered by ISO 26802 for fission nuclear reactors, by ISO 17873 for facilities other than fission nuclear reactors and by ISO 16647 for nuclear worksite and for nuclear installations under decommissioning. The facilities covered by these three standards, notably ISO 17873, include tritium as a radioactive material among the ones to be confined, but tritium is not their driver of the risks for workers and for members of the public. Nevertheless, the tritium quantities and risks from fusion facilities create specificities for a specific standard (e.g. in fusion facilities, tritium is the driver of routine and accident consequences). Therefore, the scope of this document does not cover the other facilities involved in tritium releases (ISO 17873, ISO 16647 and ISO 26802), even though these other facilities create tritium releases (e.g. non-reactor fission facilities, tritium laboratories, tritium removal facilities from fission plants, tritium defence facilities).
