Žemės ir miškų ūkio mašinos. Malkų ruošimo mašinos. Sauga

This document specifies safety requirements and their verification for the design and construction of firewood processors, designed to be used for making firewood. Firewood processors are combined machinery that cut and then split the wood. This document covers machines where the cutting is done either by a chain blade or a circular saw, and splitting movement is done horizontally or near horizontally by one or more splitting wedges. If cutting or splitting is done by other means, e.g. by guillotine blade or vertical movement splitting, this document is not applicable. This document is not applicable for machinery, where the wood is required to be moved from cutting to the splitting by manual handing by the operator. This document deals with firewood processors that are designed in a way that only one operator carries out the work process, but it is foreseeable that other operators, e.g. for loading or unloading, will work on or close to the machine. This document deals with all significant hazards, hazardous situations and hazardous events relevant to these machines, when they are used as intended and under the conditions foreseen by the manufacturer. See Clause 4 for the list of significant hazards. This document is not applicable to machines which were manufactured before the date of its publication. This document is applicable for manually operated, semi-automatic and automatic firewood processors. This document is applicable to the following possible integral features of the firewood processor: - Integral outfeed conveyors - Integral infeed conveyors - Integral hold to run operated log lifting device Other accessories or added features of firewood processors are not covered by this document. These could be e.g.: - Separate conveyors or tables that are not integral parts of the machine - Other wood lifting equipment (e.g. winch or crane) - Other separate accessories of the machine, e.g. for cleaning the wood or packing the wood.

Neorganinės trąšos. Visuminio K2O kiekio nustatymas

This document specifies two different methods (Method A and B) for the determination of the content of potassium (expressed as K2O) in inorganic fertilizers. Method A specifies a gravimetric method. Method B specifies the method using inductively coupled plasma optical emission spectrometry (ICP-OES). This document is applicable to fertilizing product blends, where the blend is a mix of at least two of the following components, fertilizers, liming materials, soil improvers, growing media, inhibitors and plant biostimulants, and where inorganic fertilizers are the highest % in the blend by mass or volume, or in the case of liquid form, by dry mass. If inorganic fertilizers are 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 Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.
