Medienos ir medienos gaminių biologinis ilgaamžiškumas. Pentachlorfenolio kiekio medienoje kiekybinis nustatymas. Dujų chromatografijos metodas

This document specifies a laboratory method of determining the pentachlorophenol content of wood. The method is applicable to all types of pentachlorophenol (PCP) in woods and wood- based materials as well as for the analysis of waste timber with respect to its pentachlorophenol (PCP) content. The method described has a measurement range from 250 μg/kg up to pentachlorophenol (PCP) contents of 5 mg/kg of dry matter. These figures refer to the given example (where an aliquot of 1 ml of the extract is used for acetylation, see 9.4). NOTE 1 If lower quantification limits are required, a higher volume of extract aliquot can be used for derivatisation. NOTE 2 This method could have some modifications with some wood species as hardwoods. In general, in the case of complex matrix, a method using mass spectrometry is used.

This document specifies a routine method for determining the organic matter and the ash content of soil improvers and growing media. NOTE The loss on ignition (LOI) is often used as an estimate for the content of organic matter in the sample. Inorganic substances or decomposition products (e.g. H2O, CO2, SO2, O2) are released or absorbed and some inorganic substances are volatile under the reaction conditions. Thus, a conversion to the organic carbon content is not possible.

Viešasis transportas. Pamatinių duomenų modelis. 5 dalis. Mokėjimo už važiavimą valdymas

1.1 General Scope of the Standard The main objective of the present standard is to present the Reference Data Model for Public Transport, based on: - the Reference Data Model, EN 12896, known as Transmodel V5.1; - EN 28701:2012, Intelligent transport systems - Public transport - Identification of Fixed Objects in Public Transport (IFOPT), although note that this particular standard has been withdrawn as it is now included within Parts 1 and 2 of this standard (EN 12896-1:2016 and EN 12896-2:2016) following their successful publication. incorporating the requirements of: - EN 15531-1 to -3 and CEN/TS 15531-4 and -5: Public transport - Service interface for real-time information relating to public transport operations (SIRI); - CEN/TS 16614-1 and -2: Public transport - 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 the understanding and the use of the model; - the data model is entirely described in UML. The following functional domains are considered: - Network Description: routes, lines, journey patterns, timing patterns, service patterns, scheduled stop points and stop places; - Timing Information and Vehicle Scheduling (runtimes, vehicle journeys, day type-related vehicle schedules); - Passenger Information (planned and real-time); - Fare Management (fare structure, sales, validation, control); - Operations Monitoring and Control: operating day-related data, vehicle follow-up, control actions; - 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); - Management Information and Statistics (including data dedicated to service performance indicators). 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 The different functional domains (enumerated above) taken into account in the present standard, and of which the data have been represented as the reference model, are described in EN 12896-1:2016, Public transport - Reference data model - Part 1: Common concepts. 1.3 Particular Scope of this Document The present document entitled Public transport - Reference data model - Part 5: Fare Management addresses Fare Information for Public Transport and incorporates the following data packages: - Fare Structure; - Access Right Assignment; - Fare Pricing; - Sales Description; - Sales Transaction; - Fare Roles; - Validation and Control; - Explicit Frames for Fares. This document itself is composed of the following parts: - Main document (normative) representing the data model for the concepts shared by the different fare domains covered by Transmodel, - Annex A (normative), containing the data dictionary, i.e. the list of all the concepts and attribute tables present in the main document together with the definitions, - Annex B (normative), providing a complement to the "Common Concepts" domain, particularly useful for parts 4 to 8 of the Public Transport Reference Data Model, Annex C (informative), indicating the data model evolutions from previous versions of Transmodel (EN 12896:2006).
