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.

Kranų sauga. Bendrasis projektavimas. 2 dalis. Apkrovos poveikiai

This document specifies load actions and load combinations for the calculation of load effects as basis for the proof of competence of a crane and its main components. It will be used together with the other generic parts of the EN 13001 series of standards, see Annex E. As such they specify conditions and requirements on design to prevent mechanical hazards of cranes and provide a method of verification of those requirements. NOTE Specific requirements for particular types of crane are given in the appropriate European product standards for the particular crane type, see Annex E. The following is a list of significant hazardous situations and hazardous events that could result in risks to persons during normal use and reasonably foreseeable misuse. Clause 4 of this document provides means to reduce or eliminate the risks of mechanical failures due to the following: a) rigid body instability of the crane or its parts (tilting); b) exceeding the limits of strength (yield, ultimate, fatigue); c) elastic instability of the crane or its parts or components (buckling, bulging). The hazards covered by this document are identified by Annex G. This document is not applicable to cranes that are manufactured before the date of its publication as EN.

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.
