Automobiliniai degalai. Butoksibenzeno kiekio nustatymas viduriniuose distiliatuose. Dujų chromatografijos naudojant liepsnos jonizacinį detektorių (GC-FID) metodas

This document specifies a test method for the determination of the content of n-butyl phenyl ether (BPE, CAS: 1126-79-0, also known as butoxy-benzene) in gas oils, kerosene, diesel fuel and biodiesel blends. The method uses a two-column gas chromatograph with an FID-type of detector. The application range is 0,27 mg/l to 19,75 mg/l of BPE, with the minimum and maximum reporting levels being 0,09 mg/l, respectively 21,89 mg/l . NOTE This corresponds to 1 % to 185 % of the average marking level of the ACCUTRACE™ Plus required by Commission Implementing Decision (EU) 2022/197 [1] of 17 January 2022 establishing a common fiscal marker for gas oils and kerosene. The method is found to be applicable to determinations beyond this range or for specific other chemical markers that fall within the distillation temperature range of middle-distillates, but for that no precision has been determined. WARNING — The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

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.

Neorganinės trąšos ir kalkinimo medžiagos. Tam tikrų elementų nustatymas. Kadmio, chromo, vario, švino, nikelio ir cinko nustatymas induktyviai susietos plazmos atominės emisijos spektrometrijos metodu (ICP‐AES), ištirpinus karališkajame vandenyje

This document specifies a method for the determination of the content of cadmium, chromium, copper, lead, nickel and zinc in fertilizers and liming materials using inductively coupled plasma-atomic emission spectrometry (ICP-AES) after aqua regia dissolution. Limits of quantification are dependent on the sample matrix as well as on the instrument, but can roughly be expected to be 0,3 mg/kg for Cd and 1 mg/kg for Cr, Cu, Ni, Pb and Zn. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants and where the following category: inorganic fertilizers and liming materials is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizers and liming materials is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. NOTE 1 The term fertilizer is used throughout this document and needs to be taken to include liming materials unless otherwise indicated. NOTE 2 Dissolution by aqua regia is equivalent to digestion and extract and digest are equivalent terms in this sense for the purposes of this standard.

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.
