Foodstuffs - Detection of food allergens by molecular biological methods - Part 7: Peanut (Arachis hypogaea) - Qualitative detection of a specific DNA sequence in food by real-time PCR

This document specifies a method for the qualitative detection of peanut (Arachis hypogaea) DNA in food using real-time PCR and targeting a multicopy mitochondrial sequence, in the context of allergen analyses. The method was previously validated in an interlaboratory study (ring trial) and applied to DNA extracted from samples that consist of defined proportions of peanut in rice biscuits, wheat biscuits, cooked sausage and milk powder. The limit of detection of the peanut real-time PCR has been determined experimentally to be at least 0,5 mg peanut/kg.

Inorganic fertilizers - Determination of specific contaminants

This document specifies references to methods for the determination of the following contaminants: mercury, cadmium, nickel, copper, zinc, arsenic, lead, chromium(VI), biuret, perchlorate, total chromium and phosphonates content in inorganic fertilizers. For the mercury, cadmium, nickel, copper, zinc, arsenic, lead, perchlorate and total chromium content: This document is applicable to 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: inorganic fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic 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. For the chromium(VI) and biuret content: This document is applicable to 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 organic matter is present in at least one of the products in the blend. In case a fertilizing product blend is composed only of inorganic products, the European Standard for inorganic fertilizers applies. 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. An overview of the references to methods for the determination of the specific contaminants is given in Table 1. NOTE 1 The determination of copper and zinc in inorganic fertilizers as micronutrients is covered by prEN 17754. NOTE 2 The determination of copper in ammonium nitrate fertilizers of high nitrogen content is covered by CEN/TS 17751.

Paints and varnishes - Evaluation of defects on coated surfaces using digital image processing - Part 1: General guidance (ISO/DIS 21227-1:2026)

ISO 21227-1:2003 gives definitions for and provides guidance in the use of optical imaging systems for the quantitative characterization of defects on coated surfaces that occur after exposure in various test methods, e.g. stone chipping, weathering or cross-cut testing. One aim of ISO 21227 is to use optical imaging to reproduce the results of already existing methods for visual assessment. Additionally, optical imaging provides further information which can be used for a more detailed evaluation of coating defects. This part of ISO 21227 contains a general introduction in optical-imaging methods and definitions. The performance of individual test methods and requirements for precision are described in other parts of the standard.

Telecommunications bonding networks for buildings and other structures

This document specifies requirements and provides recommendations for the design and installation of connections (bonds) between various electrically conductive elements in buildings and other structures, during their construction or refurbishment, in which information or telecommunications technology equipment is intended to be installed in order to: a) minimise the d.c. and a.c. potential differences in order to reduce the risk of malfunction of that equipment and interconnecting cabling due to electromagnetic disturbance; b) provide the telecommunications installation with a reliable signal reference – which may improve immunity from electromagnetic interference (EMI). The requirements of this European Standard are applicable to the buildings and other structures within premises addressed by EN 50174-2 (e.g. residential, office, industrial and data centres) but information given in this European Standard may be of assistance for other types of buildings and structures. NOTE Telecommunications centres (operator buildings) are addressed by ETSI/EN 300 253. This European Standard does not apply to power supply distribution of voltages over AC 1 000 V. Electromagnetic compatibility (EMC) requirements and safety requirements for power supply installation are outside the scope of this European Standard and are covered by other standards and regulations. However, information given in this European Standard may be of assistance in meeting the requirements of these standards and regulations.

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.
