This document specifies a method for the determination of saturated and aromatic hydrocarbons (from C10 to C50) in feed. The method has been interlaboratory validated with online-HPLC-GC-FID – see [1], [2] and [3]. This method is not intended to be applied to other matrices. The method can be used for the analysis of mineral oil saturated hydrocarbons (MOSH) and/or mineral oil aromatic hydrocarbons (MOAH). The method is applicable for feed materials, in particular vegetable oils and other fat rich feed materials, compound feeds and pre-mixtures. It is not applicable to additives or deodistillates. The method has been tested in an interlaboratory study via the analysis of both naturally contaminated and spiked samples (pre-mixture, soybean meal, sunflower seeds, chicken feed, pig feed, vegetable oil) ranging from 3 mg/kg to 286 mg/kg for MOSH and from 1 mg/kg to 16 mg/kg for MOAH. According to the results of the interlaboratory study, the method has been proven suitable for MOSH and MOAH mass concentrations, each above 10 mg/kg. However, the method was not fully validated during the collaborative study for the premixture sample due to too low concentrations of MOSH and MOAH. The method was also not fully validated during the collaborative study for the sunflower seeds sample due to a too low concentration of MOAH. NOTE The conclusions regarding MOAH are based on 4 analyte / matrix combinations while according to the IUPAC protocol [4] expects this to be a minimum of 5. In case of suspected interferences from natural sources, the fossil origin of the MOSH and MOAH fraction can be verified by examination of the pattern by GC-MS. For the determination of MOSH and MOAH in edible fats and oils, another CEN standard is also available: EN 16995. For more information see [5]. Annex C proposes a manual alternative method to online HPLC-GC-FID analysis that can be used as a screening method.

This document specifies the requirements for steel products used for industrial piping and supports. For some metallic materials other than steel, such as spheroidal graphite cast iron, aluminium, nickel, copper, titanium, requirements are or will be formulated in separate parts of this document. For metallic materials which are not covered by a harmonized material standard and are not likely to be in near future, specific rules are given in this part or the above cited parts of this document.

This Part of this European Standard specifies the requirements for inspection and testing of industrial piping as defined in EN 13480-1:2017 to be performed on individual spools or piping systems, including supports, designed in accordance with EN 13480-3:2017 and EN 13480-6:2017 (if applicable), and fabricated and installed in accordance with EN 13480-4:2017.

This Part of this European Standard specifies the requirements for fabrication and installation of piping systems, including supports, designed in accordance with EN 13480-3:2017.

This document covers standardization in the field of geological and environmental aspects, design, drilling, construction, completion, operation, monitoring, maintenance, rehabilitation and decommissioning of borehole heat exchangers for uses of geothermal energy. The direct expansion and thermal syphon techniques are excluded from this document

This document specifies the minimum requirements for the safe and independent access and use of lifts by persons, including persons with disabilities. It covers the needs of persons with disabilities according to Annex A. NOTE For guidance on solutions for increased accessibility and usability, see Annex D.

1.1 This document includes safety requirements for the design and installation of equipment that is intended for storage, handling and transportation of flat glass inside the factory. It also applies to equipment within the scope of EU Directives as well as to equipment that is covered by non harmonized documents. Annex E gives an overview of the differentiation. 1.2 This document specifies safety requirements for the following equipment: - equipment for storage provided with elements that are propelled by a drive system other than directly applied human or animal power (engine power) in order to store or retrieve glass in or from storage shelves or frames (see 3.2.2); - equipment for picking up single glass plates, firmly attached glass plates or glass packs for transportation between different locations where the retention force or lifting force is generated by engine power (see 3.3.2, 3.3.3); - equipment for transportation by special vehicles that are propelled by engine power. 1.3 This document specifies additional requirements for the following equipment that is not covered by EU Directives: - stationary, movable and mobile storage equipment (see 3.2.1, 3.2.3, 3.2.4, for requirements see Annex A); - storage equipment that is provided with manually propelled shelves or frames (see 3.2.2, for requirements see Annex B); - equipment for transportation by special vehicles that are not self propelled (see 3.4.3, for requirements see Annex C). NOTE Additional requirements covering specific hazards that are resulting from the use outside the factory are dealt with in EN 13035 2. 1.4 This document only deals with equipment which is in direct contact with the glass, with the exception of wooden packaging. Tractors, cranes, hoists and forklift trucks as well as elements of self propelled vehicles, which are not in contact with the glass (see 3.4.1), are out of the scope. This document does not apply to equipment for picking up single plates, such as manual vacuum lifting devices, lifting straps or other manual devices. This document does not cover automatic loading or unloading of storage and transportation equipment. This is covered in EN 13035-5. 1.5 This document deals with all significant hazards, hazardous situations and hazardous events, which are relevant to equipment for storage, handling and transportation of flat glass, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex D). This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards during commissioning, operation and maintenance. Noise hazards have not been considered significant for any type of equipment within the scope of this document. 1.6 This document is not applicable to equipment for storage, handling and transportation of flat glass inside the factory, which is manufactured before the date of publication of this document by CEN.
