Photovoltaics in buildings - Part 1: BIPV modules

This document applies to photovoltaic modules that contain at least one glass pane and which are used as construction products. It focuses on the properties of these photovoltaic modules relevant to essential building requirements as specified in the European Construction Product Regulation CPR 305/2011, and the applicable electro-technical requirements as stated in the Low Voltage Directive 2014/35/EU / or CENELEC standards. The CE mark of building integrated photovoltaic (BIPV) modules will thus state properties based on both documents as they are both equally applicable. This document references international standards, technical reports and guidelines. For some mounting categories, in addition, national standards (or regulations) for building products may apply in individual countries, which are not explicitly referenced here and for which harmonized European Standards are not yet available. The document is addressed to manufacturers, planners, system designers, installers, testing institutes and building authorities. This document does not address concentrating or building-attached photovoltaic modules (BAPV). This document addresses requirements on the PV modules in the specific ways they are intended to be mounted. Separable mounting structures are within the scope of EN 50583 2. NOTE For the definition of building-attached photovoltaic modules (BAPV) refer to Clause 3.

Foodstuffs - Detection of food allergens by molecular biological methods - Part 6: Wheat (Triticum L.) and Rye (Secale cereale) - Qualitative detection of a specific DNA sequence in cooked sausages by real-time PCR

This document specifies a method for the qualitative detection of DNA of the general wheat and rye in cooked sausages using real-time PCR based on the glutenin gene, in the context of allergen analyses. This document does not apply to differentiating between wheat (Triticum L.) and rye (Secale cereale). The method was previously validated in an interlaboratory study (ring trial). The limit of detection of the wheat and rye real-time PCR has been determined experimentally to be around 80 mg wheat or rye per kg for the matrix ‘cooked sausage’. For autoclaved material the detection limit can increase significantly.

Organic and organo-mineral fertilizers - Determination of the total content of specific elements by ICP-AES after digestion by aqua regia

This document specifies a method for the determination of arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), nickel (Ni)), boron (B), cobalt (Co), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca), sulfur (S) and sodium (Na) in aqua regia digests of organic, organo-mineral fertilizers, and their fertilizing product blends using inductively coupled plasma-atomic emission spectrometry (ICP-AES). It is applicable and validated for several types of matrices as indicated in Annex A. This document is applicable to the component materials “by-products”, when used as components of fertilizing products, as well as 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: organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizer 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. 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. This method is applicable to aqua regia digests prepared according to prEN 17768. NOTE Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the determination of the elements in the aqua regia digests if the user proves that the method gives the same results.
