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 9.3). 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 can be used.

Dirvožemio gerinimo medžiagos ir auginimo terpės. Organinių medžiagų aerobinio biologinio skaidymo greičio nustatymas. 1 dalis. Deguonies suvartojimo greitis (OUR)

This document describes a method to determine the stability of materials (e.g. compost, digestate) used as components (ingredients) in growing media, soil improvers and organic fertilisers by measuring the oxygen uptake rate (OUR). The oxygen uptake rate is a direct parameter for the degradation rate of biodegradable organic matter that is being broken down within a specified time period. The method is not suitable for material with a content of particle sizes > 20 mm exceeding 20 % by volume. NOTE The relation between the degradation rate and the oxygen uptake rate under the same conditions is depending on the type of material, for example by the C/N ratio. So it is important for the interpretation and limit values to be set based on the type of material.

This calculation module applies to instantaneous domestic hot water heat recovery using a counter-flow heat exchanger between the drain water and the incoming domestic cold water. This module calculates the recovered heat, to be taken into account in the overall calculation procedure of the energy performance of the building. The scope of this document is to standardize the: - required inputs; - calculation methods; - required outputs; of the instantaneous heat recovery from domestic hot water drains. This document provides a calculation method for one calculation interval. This calculation is intended to be connected to the whole building calculation model and takes into account the external conditions and system controls that may influence the instantaneous heat recovery from domestic hot water drains. This document does not apply to storage heat recovery or the use of drain water as a source for heat pumps. This document does not apply to sizing or inspection of domestic hot water heat recovery devices. Table 1 shows the relative position of this document within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000-1. NOTE 1 The same Table is found in CEN ISO/TR 52000-2, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation. NOTE 2 The modules represent EPB standards, although one EPB standard might cover more than one module and one module might be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Table A.1 and Table B.1.
