Neorganinės trąšos ir kalkinimo medžiagos. Tam tikrų elementų nustatymas. Kadmio, chromo, vario, švino, nikelio ir cinko nustatymas induktyviai susietos plazmos atominės emisijos spektrometrijos metodu (ICP‐AES), ištirpinus karališkajame vandenyje

This document specifies a method for the determination of the content of cadmium, chromium, copper, lead, nickel and zinc in fertilizers and liming materials using inductively coupled plasma-atomic emission spectrometry (ICP-AES) after aqua regia dissolution. Limits of quantification are dependent on the sample matrix as well as on the instrument, but can roughly be expected to be 0,3 mg/kg for Cd and 1 mg/kg for Cr, Cu, Ni, Pb and Zn. 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 and liming materials is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic fertilizers and liming materials 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. NOTE 1 The term fertilizer is used throughout this document and needs to be taken to include liming materials unless otherwise indicated. NOTE 2 Dissolution by aqua regia is equivalent to digestion and extract and digest are equivalent terms in this sense for the purposes of this standard.

Sveikatos informatika. Vaistų identifikavimas. Duomenų elementai ir struktūros, skirti unikaliam identifikavimui ir reglamentuotos informacijos apie farmacinius gaminius mainams (ISO 11616:2025)

ISO 11616:2017 is intended to provide specific levels of information relevant to the identification of a Medicinal Product or group of Medicinal Products. It defines the data elements, structures and relationships between data elements that are required for the exchange of regulated information, in order to uniquely identify pharmaceutical products. This identification is to be applied throughout the product lifecycle to support pharmacovigilance, regulatory and other activities worldwide. In addition, ISO 11616:2017 is essential to ensure that pharmaceutical product information is assembled in a structured format with transmission between a diverse set of stakeholders for both regulatory and clinical (e.g. e-prescribing, clinical decision support) purposes. This ensures interoperability and compatibility for both the sender and the recipient. ISO 11616:2017 is not intended to be a scientific classification for pharmaceutical products. Rather, it is a formal association of particular data elements categorised in prescribed combinations and uniquely identified when levelling degrees of information are incomplete. This allows for Medicinal Products to be unequivocally identified on a global level. References to other normative IDMP and messaging standards for pharmaceutical product information are included in Clause 2, to be applied in the context of ISO 11616:2017. Medicinal products for veterinary use are out of scope of ISO 11616:2017.

ISO 11615:2017 establishes definitions and concepts and describes data elements and their structural relationships, which are required for the unique identification and the detailed description of Medicinal Products. Taken together, the standards listed in the Introduction define, characterise and uniquely identify regulated Medicinal Products for human use during their entire life cycle, i.e. from development to authorisation, post-marketing and renewal or withdrawal from the market, where applicable. Furthermore, to support successful information exchange in relation to the unique identification and characterisation of Medicinal Products, the use of other normative IDMP messaging standards is included, which are to be applied in the context of ISO 11615:2017.

Šiluminės statybinių medžiagų ir gaminių charakteristikos. Šiluminės varžos nustatymas apsaugotos karštosios plokštės ir šilumos srauto matuoklio metodais. Vidutinės ir mažos šiluminės varžos sausi ir drėgni gaminiai

This document specifies principles and testing procedures for determining, by means of the guarded hot plate or heat flow meter methods, the thermal resistance of test specimens either in the dry state or conditioned to equilibrium with moist air, having a thermal resistance of not less than 0,1 m2·K/W and a (hygro)thermal transmissivity or thermal conductivity up to 2,0 W/(m·K). NOTE The lower limit for measurable thermal resistance is due to the effect of contact thermal resistances, which require special testing techniques described in this document. Although this document can be used for testing dry specimens of high and medium thermal resistance, i.e. on products having a thermal resistance, that is, on products with a thermal resistance of at least 0.5 m².K/W, the simpler procedures of EN 12667[3] are available for such specimen. This document does not cover methods to assess the hygrothermal transmissivity of materials in the over-hygroscopic range (i.e. when free liquid water occurs in the material in general above 95% of moisture). It applies in principle to any mean test temperature, but the equipment design in Annex D is essentially intended to operate between a minimum cooling unit temperature of -100 °C and maximum heating unit temperature of +100 °C. This document does not supply general guidance and background information (e.g. the heat transfer property to be reported, product-dependent specimen preparations, suggested materials for vapour-tight envelopes when testing moist specimens, procedures requiring multiple measurements, such as those to assess the effect of specimen non-homogeneities, those to test specimens whose thickness exceeds the apparatus capabilities, and those to assess the relevance of the thickness effect).
