Komentavimo iki data 2026-09-24

Techninė keramika (modernioji keramika, modernioji techninė keramika). Didelio grynumo bario titanato miltelių cheminės analizės metodai (ISO/DIS 21813:2026)

ISO 21813 specifies methods for the chemical analysis of fine high purity barium titanate powders used as the raw material for fine ceramics. ISO 21813 stipulates the determination methods of the barium, titanium, aluminium, cadmium, calcium, cobalt, dysprosium, iron, lead, magnesium, manganese, nickel, niobium, potassium, silicon, sodium, strontium, vanadium, zirconium, carbon, oxygen and nitrogen contents in high purity barium titanate powders. The barium and titanium contents, the major elements, are determined by using an acid decomposition-gravimetric method or an acid decomposition-inductively coupled plasma-optical emission spectrometry (ICP-OES) method. The aluminium, cadmium, calcium, chromium, cobalt, dysprosium, iron, lead, magnesium, manganese, nickel, niobium, potassium, silicon, strontium, vanadium and zirconium contents are simultaneously determined via an acid digestion-ICP-OES method. The nitrogen content is determined by using an inert gas fusion-thermal conductivity method, while that of oxygen is determined via an inert gas fusion-IR absorption spectrometry method. Finally, the carbon content is determined using a combustion-IR absorption spectrometry method or a combustion-conductometry method.

Techninė keramika (modernioji keramika, modernioji techninė keramika). Termofizikinės keraminių kompozitų savybės. Vienmačio temperatūrinio laidžio nustatymas blyksnio metodu (ISO/DIS 19629:2026)

This document describes the flash method for the determination of thermal diffusivity of ceramic matrix composites with continuous fibre reinforcement. In order to conform with the unidimensional heat transfer hypothesis, the experimental conditions are defined such that the material behaves in a homogeneous manner. This involves performing tests in one symmetry axis of the composite. The method is applicable to materials which are physically and chemically stable during the measurement, and covers the range of temperature from 100 K to 2 800 K. It is suitable for the measurement of thermal diffusivity values in the range 10−4 m2∙s−1 to 10−7 m2∙s−1.

Grūdėtosios atliekos, dumblas, dirvožemis, į dirvožemį panašios medžiagos ir nuosėdos. Išplovimas. Atitikties tyrimai nustatant išplovimą. 3 dalis. Dvipakopis partijos tyrimas, kai skysčio ir kietosios medžiagos, kurioje yra daug kietųjų dalelių, santykis 2 l/kg ir 8 l/kg, o dalelių dydis mažesnis kaip 4 mm (dydį mažinant arba nemažinant)

This document in the series specifies a compliance test providing information on leaching of granular waste materials, sludges, soil, soil-like materials and sediments under the experimental conditions specified hereafter, and particularly a liquid to solid ratio of 2 L/kg dry matter in a first step and subsequently of 8 L/kg dry matter in a second step. It applies to materials which have a particle size below 4 mm without or with size reduction. This document has been developed to investigate the leaching of inorganic and non-volatile organic substances from granular waste materials, sludges, soil, soil-like materials and sediments. It does not take into account the consequences of microbiological processes in organic degradable materials. The test procedure specified in this document produces an eluate which is subsequently characterized physically and chemically according to appropriate standard methods. This document includes two different procedures for eluate preparation prior to analysis, one procedure for non-volatile organic substances, inorganic substances and DOC and one for inorganic substances and DOC. When assessing only the leaching of inorganic substances and DOC, certain precautions needed when assessing the leaching of organic substances can in some cases be omitted. This procedure cannot be applied to materials with a water content or such a water affinity that a good mixing of the solid with the predetermined quantity of liquid is not achievable. This procedure does not apply to materials reacting with the leachant, leading, for example, to excessive gas emission, a solidifying effect or an excessive heat release. In that case, the material can be wetted prior to carrying out the leaching test. This test cannot be used alone to determine the leaching behaviour of granular waste materials, sludges, soil, soil-like materials and sediments, as specified in EN 12920. This document does not address issues related to health and safety.
