This document specifies safety requirements and their verification for the design and construction of power take-off (PTO) drive shafts and their guards linking a tractor or self-propelled machinery to the first fixed bearing of recipient machinery. It describes methods for the elimination or reduction of risks which need specific requirements including such risks arising from misuse, reasonably foreseeable by the manufacturer. It is applicable only to those PTO drive shafts and guards mechanically linked to the shaft by at least two bearings. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. This document does not deal with: - the guards totally covering, but not mechanically linked to, the PTO drive shaft; - the mechanical characteristics of PTO drive shafts, overrun devices and torque limiters; - general hazards which are dealt with in EN ISO 4254-1:2015 (see introduction). Environmental aspects have not been considered in this document. This document is not applicable to PTO drive shafts and their guards which are manufactured before the date of publication of this document by CEN.

This document, used together with EN ISO 4254-1, specifies the safety requirements and their verification for the design and construction of mounted, semi-mounted, trailed or self-propelled machines that have a combination of two or more of the following functions: loading, mixing, chopping and distributing silage and/or other feedstuffs or materials used for animal bedding such as straw, to be used by one operator only. It includes those fitted with a built-in loading crane. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. This document applies only to machines that have the following functional combinations: - mixing and distributing functions; or - mixing, chopping and distributing functions; or - loading, mixing and distributing functions; or - loading, mixing, chopping and distributing functions; or - chopping and distributing functions; or - loading, chopping and distributing functions. Silage block cutters, even if they carry out a single function, are covered by this document. This document does not apply to: - machines which pick up green fodder directly from the field; - loading cranes; - silage buckets. NOTE 1 Loading cranes are dealt with in EN 12999. NOTE 2 Autonomous silage loading, mixing and/or chopping and distributing machines (robotic feed systems) are to be dealt with in a separate standard (under preparation). This document deals with the significant hazards, hazardous situations and events relevant to machines for loading, mixing and/or chopping and distributing silage and/or other feedstuffs, when they are used as intended and under the conditions foreseen by the manufacturer as listed in Clause 4, except for the hazards arising from: - failure of the control circuit; - inadequate seating; - inadequate lighting; - travelling of machinery; - break-up of parts rotating at high speed; - cutting hazard during service on sharp parts (e.g. blades of the mixing and/or chopping device). It is not applicable to environmental hazards (except noise). It does not deal with stability when travelling. This document is not applicable to machines for loading, mixing and/or chopping and distributing silage and/or other feedstuffs which are manufactured before the date of publication of this document by CEN.

This document specifies a high performance liquid chromatographic – tandem mass spectrometry (LC-MS/MS) method for the simultaneous screening and/or determination of the eleven authorised coccidiostats (halofuginone, robenidine hydrochloride, nicarbazin, diclazuril, decoquinate, monensin sodium, salinomycin sodium, narasin, lasalocid sodium, semduramicin sodium and maduramicin ammonium alpha) contents in poultry, cattle and pig feed at additive and cross-contamination levels and of five non-registered coccidiostats (ethopabate, clopidol, ronidazole, dimetridazole and amprolium) at sub-additive levels and for the screening of the prohibited furazolidone antibiotic at sub-additive level, in the same matrices. The range of application of the method is fit for the purpose of the screening and determination of all eleven coccidiostats at the values set by European legislation, of the non-registered coccidiostats and of the screening of the banned antibiotic.

This document specifies a method for the determination of organic acids in animal feeding stuffs by Ion Chromatography with conductivity detection (IC-CD). The method is intended to be used for the determination of formic acid, lactic acid, propionic acid, citric acid, fumaric acid and malic acid as active substances in feed additives, premixtures, compound feed and water and for screening of acetic acid in the same matrices. This method determines the total extractable concentration of the above mentioned organic acids and their salts. The working range of the method must be determined for each organic acid by the user of this standard. The lower limit of the working range depends on the matrix and the interferences encountered. A working range between 10 [mg/l] and 100 [mg/l] should be achievable. The method was successfully tested in an inter-laboratory study in concentrations between 0,02 % up to 27 % of the above mentioned organic acids. NOTE Limitation occurs during simultaneous determination of high concentration of lactic acid and low concentration of acetic acid. If the ratio of concentration of lactic acid to acetic acid exceeds factor 20, the determination of acetic acid is not guaranteed. On the basis of the referred working range, sample weight and extraction volume, limits of quantification (LOQ), as calculated (Table 1) should be achievable.

This document specifies a method for the determination of benzoic acid and sorbic acid in animal feeding stuffs by high-performance liquid chromatography method with ultra-violet detection (HPLC-UV). The method is intended to be used for the determination of benzoic acid and sorbic acid as active substances in feed additives, premixtures and compound feed and for benzoic acid in water. This method determines the total extractable concentration of these organic acids and their salts. The working range of the method must be determined for each organic acid by the user of this standard. The lower limit of the working range depends on the matrix and the interferences encountered. A working range between 5 mg/l and 100 mg/l should be accessible. The method was successfully tested in an inter-laboratory study in concentrations between 0,02 % up to 9,0 %. On the basis of the referred working range, sample weigh and extraction volume, limits of quantification (LOQ), as calculated (Table 1) on the basis of a wavelength of 230 nm, should be achievable.

This International Standard specifies the requirements and test methods for their verification for inspection in use for aerial fixed wing and rotary aircraft spray systems for agriculture, horticulture forestry and human health, with respect to minimizing the risk of environmental. This part of ISO 16122 relates mainly to the condition of the equipment with respect to its potential risk for the environment and its performance to achieve good applications. NOTE: Requirements for the protection of inspectors during an inspection are given in ISO 16122-1.
