Fenoliniai ir aminoplastiniai laikančiųjų medinių konstrukcijų klijai. Klasifikavimas ir eksploatacinių charakteristikų reikalavimai

This document establishes a classification for phenolic and aminoplastic polycondensation adhesives according to their suitability for use for load-bearing timber products in defined climatic exposure conditions, and specifies performance requirements for such adhesives for the factory manufacture or factory-like manufacturing conditions of load-bearing timber products only. This document only specifies the performance of an adhesive for use in an environment corresponding to the defined conditions. The performance requirements of this document are applicable to the adhesive only, not to the manufacturing timber products. This document does not cover the performance of adhesives for on-site gluing (except for factory-like conditions) or the production of wood-based panels, except solid wood panels, or modified and stabilized wood with considerably reduced swelling and shrinkage properties, e.g. acetylated wood, heat treated wood and polymer impregnated wood. This document is primarily intended for use by adhesive manufacturers and for use in timber products bonded with adhesives, to assess or control the quality of adhesives. The requirements are applicable to the type testing of the adhesives. Production control activities are outside the scope of this document. Adhesives meeting the requirements of this document are adequate for use in load-bearing timber products, provided that the bonding process has been carried out according to an appropriate product standard.

Nuosėdos, dirvožemis, dumblas ir atliekos. Perfluoralkilų ir polifluoralkilų grupes turinčių cheminių medžiagų (PFAS) analizė efektyviosios skysčių chromatografijos ir masių spektrometrijos metodu (ISO/DIS 25652:2025)

This document specifies a method for quantitative determination of various perfluorinated hydrocarbons by means of High-Performance Liquid Chromatography (HPLC) and mass spectrometry in soil, sludge, sediment and waste (see Table 1). For many substances to which this document applies a limit of quantification (LOQ) of 0.1 to 10 μg/kgdm can be achieved. The method can be applied to the analysis of additional PFAS not specified in the scope, if validity is proven by proper in-house validation protocols. For each target compound both, eventually occurring branched, isomers and the respective non-branched isomer are quantified together. In this method the amount of linear and branched PFAS is quantified using the response factor of the linear PFAS in the calibration standard and the total area of the linear and branched PFAS (Annex 1 gives more explanation)

This document specifies procedures to determine the thermal resistance of products whose thicknesses exceed the maximum thickness for guarded hot plate or heat flow meter apparatus. Most of the procedures described in this standard require apparatus that allows tests on specimens up to 100 mm thick . This document gives guidelines to assess the relevance of the thickness effect, i.e. to establish whether the thermal resistance of a thick product can or cannot be calculated as the sum of the thermal resistances of slices cut from the product, these guidelines complement the indications given in ISO 8302:1991[1] on the guarded hot plate apparatus. This document describes testing conditions which prevent the onset of convection which could take place in some products under the considered temperature differences and thicknesses.
