Modernioji techninė keramika. Monolitinės keramikos mechaninės savybės kambario temperatūroje. 3 dalis. Subkritinio pleišėjimo parametrų nustatymas lenkiamojo stiprio bandymais, išlaikant pastovią tempimo spartą

This document specifies a method for the determination of subcritical crack growth parameters of advanced monolithic technical ceramics in the temperature range 15 °C to 30 °C by measuring the dependence of mean flexural strength on the rate of loading. The method is based on strength test procedures described in EN 843 1. The applicability of this method is limited by specific requirements for a low scatter of the initial strength of the test pieces and an upper limit of the stress load rate for the data points considered. This document is not applicable to test pieces with artificially introduced flaws or cracks.

Mechaniniai virpesiai. Rankomis laikomos ir valdomos mašinos. Vibracijų intensyvumo įvertinimo principai (ISO/DIS 20643:2026)

ISO 20643:2005 provides the basis for the drafting of vibration test codes for hand-held and hand-guided power-driven machinery. It specifies the determination of hand-transmitted vibration emission in terms of frequency-weighted root-mean-square (r.m.s.) acceleration during type testing. For machines where vibration test codes do not exist, it can also be used for determination of emission values and contains sufficient guidance for designing an appropriate test. It is applicable to hand-held power tools (e.g. chipping hammers, sanders), hand-guided powered machines (e.g. lawn mowers, single-axle tractors, vibratory rollers), and other types of powered machines fitted with handles, guiding beams or similar means of control, of all power sources (electrical, hydraulic, pneumatic, internal combustion engine, etc.). It is not applicable to fixed machinery in which the vibration is transmitted to the hands of the user through the workpiece, nor to vibration transmitted from steering wheels or control levers of mobile machinery where the operator's position is on the machine.

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: ...

Biologinis medicinos priemonių įvertinimas. 4 dalis. Medicinos priemonių sąveikos su krauju tyrimų parinkimas (ISO 10993-4:2026)

ISO 10993-4:2017 specifies general requirements for evaluating the interactions of medical devices with blood. It describes a) a classification of medical devices that are intended for use in contact with blood, based on the intended use and duration of contact as defined in ISO 10993‑1, b) the fundamental principles governing the evaluation of the interaction of devices with blood, c) the rationale for structured selection of tests according to specific categories, together with the principles and scientific basis of these tests. Detailed requirements for testing cannot be specified because of limitations in the knowledge and precision of tests for evaluating interactions of devices with blood. This document describes biological evaluation in general terms and may not necessarily provide sufficient guidance for test methods for a specific device. The changes in this document do not indicate that testing conducted according to prior versions of this document is invalid. For marketed devices with a history of safe clinical use, additional testing according to this revision is not recommended.

Plastikai. Praskiestų polimerų tirpalų klampos nustatymas kapiliariniais viskozimetrais. 3 dalis. Polietilenai ir polipropilenai (ISO/DIS 1628-3:2026)

This part of ISO 1628 defines particular conditions for determining the reduced viscosity (also known as viscosity number) and intrinsic viscosity of polyethylenes and polypropylenes at elevated temperatures (135 °C – 160 °C) in dilute solution. The viscosity of polymer solutions can be affected by fillers or additives present in the sample. The value of a reduced viscosity determined by this method can therefore be unreliable if the sample contains fillers or other additives. NOTE Reduced viscosity is also known as the Staudinger function ( Jv) and intrinsic viscosity as the Staudinger index ( Jg).
