ISO 9626:2016 applies to rigid stainless steel needle tubing suitable for use in the manufacture of hypodermic needles and other medical devices primarily for human use. It provides requirements and test methods for the tubes manufactured for needles as component used in medical devices. Additional performance testing on the tube aspect may be required when the component is incorporated in the ready-to-use device. It specifies the dimensions and mechanical properties of steel tubing of designated metric sizes 3,4 mm (10 Gauge) to 0,18 mm (34 Gauge). It does not apply to flexible stainless steel tubing because the mechanical properties differ from those specified for rigid tubing in ISO 9626:2016. However, manufacturers and purchasers of flexible tubing are encouraged to adopt the dimensional specifications given in ISO 9626:2016.

This document specifies requirements for high chromium white cast iron grit, as supplied for blast-cleaning processes. It specifies ranges of particle sizes, together with corresponding grade designations. Values are specified for hardness, density, defect/structural requirements, metallographic structure and chemical composition. The requirements specified in this document apply to abrasives supplied in the new condition only. They do not apply to abrasives either during or after use. High chromium white cast iron grits are used in both static and site blasting equipment. They are most often selected where there is a possibility for the recovery and re-use of the abrasive. NOTE 1 Although this document has been developed for preparation of steelwork, these materials are predominantly used for non-ferrous substrates. The properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques, and can be used for applications where no subsequent coating is applied. NOTE 2 Whenever dissimilar metals are used together, galvanic corrosion can occur.

1.1 General scope of the Standard The main objective of this European Standard is to present the Public Transport Reference Data Model based on: - the Public Transport Reference Data Model published 2006 as EN12896 and known as Transmodel V5.1, - the model for the Identification of Fixed Objects for Public transport, published 2009 as EN 28701and known as IFOPT, incorporating the requirements of - EN15531-1 to 3 and TS15531-4 and 5: Service interface for real-time information relating to public transport operations (SIRI), - TS16614-1 and 2: Network and Timetable Exchange (NeTEx), in particular the specific needs for long distance train operation. Particular attention is drawn to the data model structure and methodology: - the data model is described in a modular form in order to facilitate understanding and use of the model, - the data model is entirely described in UML. In particular, a Reference Data Model kernel is described, referring to the data domain: - Network Description: routes, lines, journey patterns, timing patterns, service patterns, scheduled stop points and stop places. This part corresponds to the network description as in Transmodel V5.1 extended by the relevant parts of IFOPT. Furthermore, the following functional domains are considered: - Timing Information and Vehicle Scheduling (runtimes, vehicle journeys, day type-related vehicle schedules) - Passenger Information (planned and real-time) - Operations Monitoring and Control: operating day-related data, vehicle follow-up , control actions - Fare Management (fare structure and access rights definition, sales, validation, control) - Management Information and Statistics (including data dedicated to service performance indicators). - Driver Management: - Driver Scheduling (day-type related driver schedules), - Rostering (ordering of driver duties into sequences according to some chosen methods), - Driving Personnel Disposition (assignment of logical drivers to physical drivers and recording of driver performance). The data modules dedicated to cover most functions of the above domains will be specified. Several concepts are shared by the different functional domains. This data domain is called “Common Concepts”. 1.2 Functional domain description 1.2.1 Public transport network and stop description The reference data model includes entity definitions for different types of points and links as the building elements of the topological network. Stop points, timing points and route points, for instance, reflect the different roles one point may have in the network definition: whether it is used for the definition of (topological or geographical) routes, as a point served by vehicles when operating on a line, or as a location against which timing information like departure, passing, or wait times are stored in order to construct the timetables. The line network is the fundamental infrastructure for the service offer, to be provided in the form of vehicle journeys which passengers may use for their trips. The main entities describing the line network in the reference data model are the line, the route and the journey pattern, which refer to the concepts of an identified service offer to the public, the possible variants of itineraries vehicles would follow when serving the line, and the (possibly different) successions of stop points served by the vehicles when operating on the route. The functional views of the network are described as layers. A projection is a mechanism enabling the description of the correspondence between the different layers. This mapping between the layers is particularly useful when spatial data from different environments (sources, functional domains) have to be combined. An example of such a situation is the mapping of the public transport network on the road network. (...)

This document describes a highly specific method for the enumeration of Escherichia coli (E. coli) in water. The method is based on membrane filtration followed by culture at 44 °C on chromogenic agar medium containing an ingredient for the detection of the enzyme ß-glucuronidase, and calculation of the number of target organisms in the sample[5,6,13]. Because of the high specificity of the method, this document is suitable for waters with high levels of background bacteria, such as surface waters including bathing water and wastewater provided that they contain little particulate or colloidal matter relative to the E. coli concentration. The method can be used for fresh water and, with an adaptation, for marine water. E. coli strains which do not grow at 44 °C and those that are ß-glucuronidase negative, such as E. coli O157, will not be detected as E. coli by this method. This method is not applicable to the enumeration and detection of coliform bacteria other than E. coli.
