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.

Eurokodas 1. Poveikiai konstrukcijoms. 4 dalis. Silosai ir rezervuarai

1.1 Scope of EN 1991-4 (1) This document provides rules for calculating actions for the structural design of silos and tanks. NOTE 1 Silos are used for the storage of particulate solids. Tanks are used for the storage of liquids. NOTE 2 For limitations on rules for silos given in this document, see 1.3. NOTE 3 For limitations on rules for tanks given in this document, see 1.4. (2) This document includes some provisions for actions on silo and tank structures that are not only associated with the stored particulate solids or liquids (e.g. the effects of thermal differentials) but substantially affected by them. NOTE Liquid loads on tanks are very precisely defined. Many loads on silos are not known with great precision. This document provides guidance for many practical situations for which very limited certain knowledge is available, and the information is derived from the limited experimental and analytical information available, coupled with conclusions drawn from failure investigations. The information is not based on a sound statistical treatment of experimental data. (3) This document is intended for use with concrete, steel, aluminium, timber and FRP storage structures. NOTE FRP is the standard acronym for fibre reinforced polymer materials. (4) This document is also applicable for the structural assessment of existing silos and tanks, unless otherwise specified by the relevant authority or, if not specified, agreed between the relevant parties for the specific project. NOTE 1 Changes in filling or discharge arrangements, changes in the wall friction of inner surfaces, or in the use of the silo, including storage of different particulate solids, can be reasons for assessing existing silos. NOTE 2 Differentiation of the liquid stored can be a reason for assessing existing tanks. 1.2 Assumptions (1) The assumptions of EN 1990-1 apply. (2) This document is intended to be used in conjunction with EN 1990 1, with the other parts of EN 1991, EN 1992, EN 1993, EN 1995, EN 1997, EN 1998 and EN 1999 where relevant to the design of silos and tanks. 1.3 Limitations on silos 1.3.1 Geometrical limitations (1) The following geometrical limitations apply to the design rules for silos and silo batteries (see 3.2.59 and 3.2.60) covered by this document: - the silo planform cross-section shapes are limited to those shown in Figure 1.1c. NOTE 1 Further information concerning planform cross-section geometries is given in Clause 7. NOTE 2 For the determination of the effective diameter dc of the silo see Figure 1.1c; - the following dimensional limitations on the aspect ratio for free-standing single cell silos hc/dc, the overall height hb and the effective diameter dc apply (see Figure 1.1): hc/dc < 10 (1.1) hb < 100 m (1.2) dc < 60 m (1.3) NOTE 3 See Figure 1.1 for hc, dc and hb. - the structural transition lies in a single horizontal plane (see Figure 1.1a). [Figure 1.1 - Silo forms showing dimensions and pressure notation] (2) Only hoppers that are conical (i.e. axisymmetric), rectangular pyramidal with a/b ≤ 1,5, wedge-shaped (i.e. with two vertical end walls on opposite sides) or oblique are covered by this document. Other hopper shapes and hoppers with internal structures require special considerations. (3) Silos with an oblique conical hopper used to achieve an eccentric outlet are covered by this document. (4) Silos with an oblique hopper are covered, but generally silos with a systematically non-symmetric geometry are not specifically covered by this document. These situations include a chisel hopper (i.e. a wedge hopper beneath a circular cylinder) and hoppers with an elongated outlet other than wedge shaped. 1.3.2 Limitations on the stored particulate solids (1) The following limitations on the stored particulate solids apply to the design rules for silos contained in this document: ...

NOTE 1 Provisions in EN 1991 1 8 are limited to hydrodynamic actions that can be directly quantified in terms of wave and/or current induced pressures and associated forces and moments on structures or structural parts. NOTE 2 As opposed to offshore conditions, waves or currents in the coastal zone are generally affected by the presence of the seabed or shore. NOTE 3 The coastal zone is typically defined as the area between the shoreline and the deep-water limit. (2) EN 1991 1 8 describes the principles for defining the hydrodynamic conditions to be used for design, including sea water levels. (3) EN 1991 1 8 addresses specifically actions from currents and waves on the following structure types: — cylindrical structures; — subsea pipelines; — suspended decks; — vertical face structures; — permanently moored floating structures. NOTE 1 Additional guidance can be needed for: — moored structures in the coastal zone for renewable energy production or related to oil and gas production or processing; — moored structures spanning areas with variable wave and current states (e.g. floating aquaculture farms or floating bridges). NOTE 2 For hydraulic pressures caused by quasi-static water levels, and ground water, see EN 1997 (all parts). (4) Actions addressed in EN 1991 1 8 do not cover: — hydraulic resonance in sheltered areas or basins (phenomena also known as harbour resonance); — translation waves, e.g. tsunamis; — waves and currents induced by maritime operations, i.e. vessel wake, berthing and mooring; — hydrodynamic actions induced by earthquakes; — ice-induced pressures and forces; — coastal structures where flood risk and/or erosion or sediment management is the dominant function. 1.2 Assumptions (1) The assumptions given in EN 1990 apply to this document. (2) In addition, it is assumed that actions from waves and currents on coastal structures are determined by personnel appropriately qualified and experienced in the following fields: a) physical coastal environment including physics of waves and currents, statistical properties and propagation of such; b) marine hydrodynamics, wave and current interaction with structures in general and wave and current actions on structures in the coastal zone including i) fixed structures, and ii) floating structures; c) advanced methods including probabilistic methodology and physical model testing.

1.1 Scope of prEN 1991-1-6 (1) prEN 1991-1-6 provides guidance and general rules on the determination of actions relevant for the design of buildings and civil engineering works, including geotechnical structures, for their execution stage. NOTE Actions for design during execution include those that only arise from execution activities and act during execution, termed construction actions (for example personnel and hand tools, auxiliary structures, equipment and elements used during execution), and others that are present during the service life of the completed structure (for example self-weight, wind, etc.) but which can act differently and/or have different values during execution. (2) prEN 1991-1-6 provides guidance and general rules for the determination of actions for the design of auxiliary structures, elements and equipment used during execution in case they are designed to the Eurocodes and not to other European Standards. NOTE Other European Standards (e.g. EN 12810, EN 12811, EN 12812) provide specific rules for certain types of auxiliary structures, equipment and elements used during execution. (3) prEN 1991-1-6 gives rules for buildings and bridges during execution to supplement the provisions in EN 1990. NOTE For combination rules for execution, see EN 1990. 1.2 Assumptions (1) The general assumptions given in EN 1990 apply. (2) The application of this document follows the limit state principle and is based on the partial factor method, unless explicitly prescribed differently. (3) The verification of buildings and civil engineering structures in transient design situations is undertaken in accordance with the Eurocodes, accounting for the interaction with any auxiliary structures, elements and/or equipment. (4) When using European product standards covering auxiliary structures, equipment and elements used during execution, it is assumed that the design basis, design requirements and, if provided, the safety and operational design limits specified in these product standards are taken into account. (5) Adequate planning, documentation, communication, control and supervision are provided during execution, involving all relevant parties. NOTE Execution of a structure can involve interaction between several parties from diverse engineering fields, responsible for the design, fabrication, transportation and execution of different subsystems used during the execution of a structure.

Within the context of the ISO/IEEE 11073 family of standards for device communication, a normative definition of the communication between personal basic electrocardiograph (ECG) devices and managers (e.g. cell phones, personal computers, personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability is established in ISO/IEEE11073-10406:2012. Appropriate portions of existing standards including ISO/IEEE 11073 terminology and IEEE 11073-20601 information models are leveraged. The use of specific term codes, formats and behaviours in telehealth environments restricting optionality in base frameworks in favour of interoperability is specified. A common core of communication functionality for personal telehealth basic ECG (1- to 3-lead ECG) devices is defined. Monitoring ECG devices are distinguished from diagnostic ECG equipment with respect to support for wearable ECG devices, limiting the number of leads supported by the equipment to three, and not requiring the capability of annotating or analysing the detected electrical activity to determine known cardiac phenomena. ISO/IEEE 11073-10406:2012 is consistent with the base framework and allows multifunction implementations by following multiple device specializations (e.g. ECG and respiration rate).

Geografinė informacija. Geodezinės koordinatės. 2 dalis. Geodezinių antžeminių stočių unikalusis identifikavimas (ISO/DIS 19161-2:2026)

This standard will provide a description of the numbering system replacing the DOMES numbering. The description of the DOMES numbering can be found in MERIT/COTES joint working groups, MERIT campaign: connection of reference frames, implementation plan, 1983. The standard will provide to the geodetic data producers and users a proper identification of the permanently instrumented stations, (e.g. those used in the production of the International Terrestrial Reference Frame and other similar stations), with special emphasis on the backward compatibility with existing DOMES numbers, which will have a positive impact on interoperability issues when merging several data from different communities. This standard will: • support interoperability among GNSS providers (GPS, GLONASS, GALILEO, BEIDOU, …) • clarify the potential confusion between communities which have already adopted their own numbering systems • support the UNGGIM GGRF resolution on global geodetic infrastructure.
