This document specifies terms and definitions for different PVC based materials used for the production of unplasticized polyvinylchloride (PVC-U) profiles for windows and doors. It describes the content and meaning of post-consumer and post-industrial recyclate as it is used in new products. It distinguishes between different PVC recepies used in production for PVC window and door profiles. This document shall serve as the reference standard for definitions used in related standards such as all parts of EN 12608, EN 17410 or standards for PVC based profiles for building applications.

This European Standard specifies minimum requirements for design and testing of contents gauges, which are directly connected to transportable tanks, drums, cylinders and static LPG tanks above 0,5 l water capacity excluding those used for automotive containers. This European Standard does not apply to refineries or other process plants.

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
