prEN 820-5 Viešoji apklausa

Komentavimo iki data 2026-07-23

Modernioji techninė keramika. Monolitinės keramikos termomechaninės savybės. 5 dalis. Tampros modulių nustatymas aukštoje temperatūroje

This part of EN 820 describes methods for determining the elastic moduli, specifically Young's modulus, shear modulus and Poisson's ratio, of advanced monolithic technical ceramics at temperatures above room temperature. The standard prescribes three alternative methods for determining some or all of these three parameters: A the determination of Young's modulus by static flexure of a thin beam in three- or four-point bending. B the determination of Young's modulus by forced longitudinal resonance, or Young's modulus, shear modulus and Poisson's ratio by forced flexural and torsional resonance, of a thin beam. C the determination of Young's modulus from the fundamental natural frequency of a struck bar (impulse excitation method). This part of EN 820 extends the above-defined room-temperature methods described in EN 843-2 to elevated temperatures. All the test methods assume the use of homogeneous test pieces of linear elastic materials. The test assumes that the test piece has isotropic elastic properties. At high porosity levels all of the methods can become inappropriate. The maximum grain size (see EN 623-3), excluding deliberately added whiskers, should be less than 10 % of the minimum dimension of the test piece. NOTE 1 Method C in EN 843-2 based on ultrasonic time of flight measurement has not been incorporated into this part of EN 820. Although the method is feasible to apply, it is specialised, and outside the capabilities of most laboratories. There are also severe restrictions on test piece geometries and methods of achieving pulse transmission. For these reasons this method has not been included in EN 820-5. NOTE 2 The upper temperature limit for this test depends on the properties of the test pieces, and can be limited by softening within the timescale of the test. In addition, for method A there can be limits defined by the choice of test jig construction materials.

Reikalavimai, keliami lygiagrečiai prie skirstomųjų tinklų jungiamoms elektrinėms. 10 dalis. Elektros energijos gamybos blokų atitikties vertinimo bandymai

The purpose of this document is to provide technical guidance for tests on generating units, interface protection and generating plant controller to evaluate their electrical characteristics. NOTE 1 Mechanical issues are taken into account as far as they influence the electrical characteristics. NOTE 2 Electrical energy storage systems (EESS) in meeting the conditions of 50549-1 and 50549-2 are considered as generating units. The evaluation results are intended to be used to demonstrate conformity of generating units, interface protection and generating plant controller to technical requirements for grid connection. In this context the evaluation results can also be used as part of a certification programme. NOTE 3 Besides the type test results of the generating units, interface protection and generating plant controller all additional elements for connection to the grid (e.g. transformer, cabling, multiple units) are considered in the evaluation of the final installation of a generating plant. The requirements intended to be evaluated are covered in the following standardization documents: - EN 50549-1:2019: Requirements for generating plants to be connected in parallel with distribution networks - Part 1: connection to a LV distribution network - Generating plants up to and including Type B - EN 50549-2:2019: Requirements for generating plants to be connected in parallel with distribution networks - Part 2: Connection to a MV distribution network - Generating plants up to and including Type B If grid connection requirements are dealt with in other documents or for other generating module types, where no specific testing procedure is provided, the testing methods described in this document can be used, if applicable. This document provides evaluation criteria for the conformity assessment of generating units with respect to the above mentioned standardization documents, based on type testing. However, some requirements are applicable on the generating plant level. The assessment of the conformity to these plant requirements is out of scope of this document. Nevertheless, this document can be used to show the capabilities of a generating unit to be used in a generating plant. As a consequence, it is possible that the conformity assessment of a generating unit does not cover all aspects of the above mentioned standardization documents, typically when a requirement is evaluated on plant level. Therefore, the conformity assessment report indicates clearly which clauses of this document are covered and which clauses are not covered. This document recognizes the existence of specific technical test requirements within several member states and these must be complied with.

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.
