Grūdėtosios atliekos, dumblas, dirvožemis, į dirvožemį panašios medžiagos ir nuosėdos. Išplovimas. Atitikties tyrimai nustatant išplovimą. 1 dalis. Vienpakopis partijos tyrimas, kai skysčio ir kietosios medžiagos santykis 2 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. 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 are 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.

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: ...

Plastikai. Praskiestų polimerų tirpalų klampos nustatymas kapiliariniais viskozimetrais. 2 dalis. Polivinilchloridinės dervos (ISO/DIS 1628-2:2026)

1.1 This document specifies conditions for the determination of the reduced viscosity (also known as viscosity number) and K-value of PVC resins. It is applicable to resins in powder form which consist of homopolymers of the monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but where vinyl chloride is the main constituent. The resins can contain small amounts of unpolymerized substances (e.g. emulsifying or suspending agents, catalyst residues, etc.) and other substances added during the course of the polymerization. This document is not applicable, however, to resins having a volatile-matter content in excess of 0,5 % ± 0,1 %, when determined in accordance with ISO 1269:2006. In addition to this, it is not applicable to resins which are not entirely soluble in cyclohexanone. 1.2 The reduced viscosity and K-value of a particular resin are related to its molecular mass, but the relationship varies depending on the concentration and type(s) of other monomer(s) present. Hence, homopolymers and copolymers having the same reduced viscosity or K-value can have different molecular masses. 1.3 The values determined for reduced viscosity and K-value, for a particular sample of PVC resin, are influenced differently by the concentration of the solution chosen for the determination. Hence the use of the procedures specified in this document only gives values for reduced viscosity and K-value that are comparable when the concentrations of the solutions used are identical. 1.4 The experimental procedures specified in this document can also be used to characterize the polymeric fraction obtained during the chemical analysis of a PVC composition. However, the values calculated for the reduced viscosity and K-value in these circumstances can deviate form the correct values for the resin used to produce the composition because of the impure nature of the recovered polymer fraction.

Inžinerinių tinklų įrenginių atsparumo ugniai bandymai. 14 dalis. Viename paviršiuje esančių angų sandarinimo priemonės

This part of the EN 1366 series specifies a method of test and criteria for the evaluation (including field of direct application rules) of the ability of a partial penetration seal to maintain the fire resistance of a separating element at the position at which it has been penetrated by a device or devices that passes through one face of the element only. Partial penetration seals are used to seal apertures for electrical sockets, downlighters, media devices, cables and any item which requires an opening to be made in one face of the element of construction but does not include a device which passes through both faces. Supporting constructions are used in this part of the EN 1366 series to represent separating elements such as walls or floors. The supporting construction shall be a system that has been subject to a fire test in accordance with one of the following standards: EN 13381 1 for horizontal membranes, EN 13381 2 for vertical membranes, EN 1364 1 or EN 1365 1 for walls, EN 1366 3 for walls based on a standard supporting construction, or EN 1364 2 or EN 1365 2 for floors. This is referred to throughout this document as the applicable test standard for the supporting construction. This part of the EN 1366 series is used in conjunction with EN 1363 1. The purpose of a test described in this part of the EN 1366 series is to assess the integrity and insulation performance of the partial penetration seal, of the partially penetrating service(s) or device(s) and of the separating element in the surrounding area of the partial penetration seal. Where partial penetration seals are installed in loadbearing elements, it is possible that the loadbearing capacity is also considered. It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes. Tests in accordance with this part of the EN 1366 series are not intended to supply any information on the ability of the partial penetration seal to withstand stress caused by movements or displacements of the penetrating devices. The risk of spread of fire downwards cannot be assessed with this test. Tests in accordance with this part of the EN 1366 series do not address any risks associated with leakage of dangerous liquids or gases caused by failure of the device in case of fire.
