5.13 HPLC apparatus comprising the following: 5.13.1 Injection system, capable of injecting e.g. 1 000 µl. Total loop injection is recommended. In the case that a different volume is used, it shall be ensured that the limit of detection (LOD) for the system is ≤ 0,05 µg/kg (signal-to-noise-ratio = 3) and the limit of quantification (LOQ) is ≤ 0,1 µg/kg […]

6 Requirements 6.1 Siting criteria The siting requirements for TGM measurements are given in Annex A. 6.2 Method requirements The method for the measurement of total gaseous mercury concentrations in ambient air shall be an automated method based on Atomic Absorption Spectrometry or Atomic Fluorescence Spectrometry, as specified in Annex V.III of Directive 2004/107/EC. 6.3 Method detection limit The detection […]

4 Principle of mercury deposition determinations Atmospheric deposition is defined as the sum of the depositions of sedimenting particles, non-sedimenting particles and gases. Total atmospheric deposition is the sum of dry deposition and wet deposition. Bulk deposition is the sedimenting part of the atmospheric deposition. There is no method available to determine total atmospheric deposition in one measurement. The determination […]

1 Scope This European Standard specifies the requirements and associated test methods that apply to semifinished products such as rods, hollow bars and plates made from thermoplastic materials. These semifinished products are used predominantly for the manufacture of finished parts by means of machining. 2 Normative references The following referenced documents are indispensable for the application of this document. For […]

1 Scope This European Standard specifies a system for the classification of techniques for renovation and repair of drains and sewers outside buildings, operated under gravity or pressure, including pipes, connections and manholes. It defines and describes families of techniques and their different generic methods and materials used. This European Standard does not describe specific products. For each technique family […]

1 Scope This European Standard specifies a method for the determination of patulin in fruit juices and fruit-based purée, such as baby food purée, using high performance liquid chromatography with ultra-violet detection (HPLC-UV). Using naturally contaminated and spiked samples this method has been validated for the determination of patulin in apple juice, at levels ranging from 3,0 µg/kg to 15,5 […]

1 Scope This European Standard specifies a method for the determination of deoxynivalenol (DON) in cereals (grain and flour), cereal based foods and cereal based foods for infants and young children by high performance liquid chromatography (HPLC) with immunoaffinity cleanup and UV detection. This method has been validated in three interlaboratory studies. The first study was for the analysis of […]

1 Scope This document specifies the procedure for the extraction of phosphorus soluble in cold alkaline ammonium citrate. The method is applicable for disintegrated phosphates exclusively. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including […]

1 Scope This European Standard specifies the dry procedure for the determination of the fineness of grinding, which is applicable to all EC type fertilizers in which requirements are given of fineness of grinding using 0,630 mm and 0,160 mm. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the […]

1 Scope This European Standard specifies the packing process for objects considered by the owner/custodian as ready to be moved. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 15898:2011, Conservation […]
