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 a qualitative procedure to qualifying leather animal species of (fibrous) protein from leather by MALDI-TOF mass spectrometer (MS). The composition of other fibres can be measured by methods described in the ISO 1833 series. Both results are then combined to determine the whole composition of fibres (see Annex C as an example of mixtures of (fibrous) protein from leather and polyester). The method is based on a preliminary identification, by light microscopy, of all fibres in a blend on the basis of their morphology, according to ISO/TR 11827.

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.

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.

Žemės ūkio mašinos. Priekiniai krautuvai. Sauga

This document specifies safety requirements and their verification for the design and construction of front loaders designed to be mounted on agricultural and forestry tractors (as defined in the Regulation EU 167/2013). It deals with all significant hazards, hazardous situations and events relevant to front loaders when used as intended and under the conditions of misuse which are reasonably foreseeable. This includes hazards related to the handling of unit loads during operations (for example, using bale forks), hazards related to mounting/demounting the lifting arms to/from the frame mounted on the tractor, and also hazards related to devices for mounting/demounting attachments to/from the lifting arms. In addition, it specifies the type of information on safe working practices. Hazards related to the mounted attachments with or without powered functions are excluded, as well as hazards related to visibility and those related to the mobile elevating work platform applications to a front loader, because the front loader is not designed to lift and/or transport people. Front loaders with fully or partially self-evolving behaviour or logic and/or with varying levels of autonomy are also excluded. Environmental aspects, other than noise, have not been considered in this document. Noise is not relevant for front loaders. This document is not applicable to front loaders which are manufactured before the date of its publication as EN.
