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.

Naftos ir dujų pramonė, įskaitant mažesnio anglies dioksido pėdsako energijos gamybą. Viso žiedo ovalėjimo bandymo metodas plieninių vamzdynų atsparumui pleišėjimui rūgštinėje aplinkoje įvertinti (ISO 3845:2024)

This document gives a method for determining the resistance to cracking of steel pipes in sour service. This test method employs a full-scale test specimen consisting of a short length of pipe (a ‘full ring’), sealed at each end to contain the sour test environment within. The test method applies to any pipe; seamless, longitudinally welded (with or without filler), helical welded, and to girth welds between pipes. NOTE 1 The specimen is usually a pipe but can also consist of flange neck or section of a bend, or other tubular component or a combination of the above. NOTE 2 This test method can also be used for corrosion resistant alloys (CRAs). The method utilizes ovalization by mechanical loading to produce a circumferential stress, equal to the target hoop stress, at two diametrically opposite locations on the inside surface of the test specimen. The test specimen is then subjected to single sided exposure to the sour test environment. NOTE 3 The test also allows measurement of hydrogen permeation rates.

Pienas, pieno produktai, mišiniai kūdikiams ir suaugusiesiems. Riebalų rūgščių sudėties nustatymas. Kapiliarinės dujų chromatografijos metodas (ISO/FDIS 16958:2025)

ISO 16958:2015 specifies a method for the quantification of individual and/or all fatty acids in the profile of milk, milk products, infant formula and adult nutritional formula, containing milk fat and/or vegetable oils, supplemented or not supplemented with oils rich in long chain polyunsaturated fatty acids (LC-PUFA). This also includes groups of fatty acids often labelled [i.e. trans fatty acids (TFA), saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), omega-3, omega-6 and omega-9 fatty acids] and/or individual fatty acids [i.e. linoleic acid (LA), α-linolenic acid (ALA), arachidonic acid (ARA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)]. The determination is performed by direct transesterification in food matrices, without prior fat extraction, and consequently it is applicable to liquid samples or reconstituted powder samples with water having total fat ≥ 1,5 % m/m. The fat extracted from products containing less than 1,5 % m/m fat can be analysed with the same method after a preliminary fat extraction using methods referenced in Clause 2. Dairy products, like soft or hard cheeses with acidity level ≤ 1 mmol/100 g of fat, can be analysed after a preliminary fat extraction using methods referenced in Clause 2. For products supplemented or enriched with PUFA with fish oil or algae origins, the evaporation of solvents should be performed at the lowest possible temperature (e.g. max. 40 °C) to recover these sensitive fatty acids.

Cemento bandymų metodai. 10 dalis. Vandenyje tirpaus chromo (VI) kiekio cemente nustatymas

This document specifies the method for the determination of the water-soluble chromium (VI) content of cement. A reference method is described consisting of two stages, an extraction procedure and an analysis of the filtered extract. Guidance on other extraction procedures, suitable for screening tests, for factory production control or other purposes, is given but in case of dispute or failure to comply with a regulatory limit only the reference method is used. The reference method has alternatives whereby the filtered extract can be subjected to an oxidation step or not. The criteria by which the appropriate procedure is selected are set down. Other instrumental procedures can be used for the analysis of the filtered extract provided they are calibrated against the analysis of the filtered extract using the reference procedure. In the case of a dispute, only the reference method is used. This document specifies, for the determination of water-soluble chromium (VI) in the filtered extract, the reference methods (colorimetric determination by diphenylcarbazide in acidic conditions) and another method for the determination of total water-soluble chromium (by inductively coupled plasma optical emission spectroscopy, ICP-OES). The ICP-OES determines the total chromium content independently of the chemical species, i.e. whether it is present as chromium (III) or chromium (VI), for example. Experience has demonstrated that soluble chromium (VI) is predominantly present during the processing phase, such that, in most cases, the determination of total water-soluble chromium effectively reflects the chromium (VI) content. The water-soluble chromium (VI) content of cement can therefore be assessed conservatively using the method based on ICP-OES described in this document. In the case of a dispute, only the reference methods are used. This document specifies a method that applies to cements. NOTE 1 Annex A provides guidance on the possible application of this document to the determination of the water-soluble chromium (VI) content of cement-containing preparations. NOTE 2 Annexes B and C provide information on other test procedures based on paste extraction and thus depart from the performance of cement in its normal conditions of use. They can be carried out with or without the oxidation process. It is important that users are aware that results using these methods might be significantly different to those obtained by the reference method. In the case of dispute or failure to comply with the regulatory limit, only the reference method is used. NOTE 3 Annex D provides guidance on a method for determination of the excess reducing agent content of cement as used in the factory internal control system of some countries. It is important that manufacturers using such an internal control method ensure themselves of the relevance of results in comparison with testing by the reference method.
