This document is applied to fuel fabrication. It describes the ceramographic procedure used to prepare sintered (U,Pu)O2 pellets for qualitative and quantitative examination of the (U,Pu)O2 pellet microstructure. The examinations are performed a) before any treatment or any etching, and b) after thermal treatment or after chemical or ion etching. They allow — observation of any cracks, intra- and intergranular pores or inclusions, and — measurement of the grain size, porosity and plutonium homogeneity distribution. The mean grain diameter is measured by one of the classic methods: counting (intercept method), comparison with standard grids or typical images, etc.[2]. The measurement of individual grain sizes requires uniform development of the microstructure over the entire specimen. The plutonium cluster and pore distribution and localization are generally analysed by automatic image analysis systems. The plutonium distribution is usually revealed by chemical etching or by alpha autoradiography. A scanning electron microscope (SEM) or a microprobe can also be used. In this case an additional preparation can be needed depending on the equipment used. This preparation is not in the scope of this standard.

This document establishes a method of using geographic location referencing (GLR) that can be used by relevant TPEG applications. The GLR type, defined in this document, is used for defining geographic location references (points, polylines and geographical areas). The GLR method is intended to be one of the methods that can be transported inside a TPEG-Location Referencing Container (TPEG-LRC) for those TPEG applications providing information for primarily geographical locations (e.g. weather). The GLR specification is deliberately kept basic and compact, so that it can also be employed advantageously in non-navigation devices, for simple TPEG services such as weather information, safety alerts, etc. As such, the GLR location referencing method is intended to be complementary to map-related location referencing methods, where the focus is on the referencing of anthropogenic artefacts such as roads and highways. For this reason, the scope of GLR is limited to geographic locations on the Earth’s surface.

This document specifies a procedure for the parallel determination of glycidol together with 2-MCPD and 3-MCPD present in bound or free form in oils and fats. The method is based on alkaline-catalysed ester cleavage, transformation of the released glycidol into monobromopropanediol (MBPD) and derivatisation of the derived free diols (MCPD and MBPD) with phenylboronic acid (PBA). Though free MCPD and glycidol are supposed to be present in fats and oils in low to negligible quantities only, in the event that free analytes are present, they would contribute proportionately to the results. The results always being the sum of the free and the bound form of a single analyte. This method is applicable to solid and liquid fats and oils. This document can also apply to animal fats and used frying oils and fats, but a validation study is undertaken before the analysis of these matrices. Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this document.

This document also discusses the choices that arise in structuring RDF documents equivalent to documents in XML, and FIX Tag-Value format balancing considerations such as preserving the order of parts of the message versus creating graphs that are suitable for RDFS and OWL inference.

This document describes the “public transport information service” (PTS) application, which is intended to cover all modes of public (i.e. collective) transport, both for inter-urban and intra-urban travel. The PTS application is designed to allow the efficient and language-independent delivery of public transport information directly from a service provider to end-users. The PTS application design is based on three main use cases. — Provision of alert information: an alert is a warning that indicates an emergency situation. This case is specifically relevant for broadcast/push mode, for major deviations or disruptions which are relevant for a large number of travellers. A dedicated alert request is also defined and can be used if a backchannel is available. — Timetable information, both scheduled and real time: this information is in some cases relevant for broadcast, e.g. in case of large events for the transport modalities to/from the event site. A dedicated timetable request is also defined and can be used if a backchannel is available. — Individual requests for trip information (backchannel is required). The PTS application focuses on providing core information regarding public transport in order to ensure the compactness of the TPEG application. Specific information as provided in typical public transport apps (e.g. fare information) is not in the scope of this document.
