1.1 Scope of EN 1991-1-3 (1) EN 1991-1-3 gives principles and rules to determine the values of loads due to snow to be used for the structural design of buildings and civil engineering works. (2) This document does not apply to sites at altitudes above 1 500 m, unless otherwise specified. NOTE For rules for the treatment of snow loads for altitudes above 1 500 m, see 6.1. (3) This document does not give guidance on specialist aspects of snow loading, for example: - impact snow loads resulting from snow sliding off or falling from a higher roof; - changes in shape or size of the construction works due to the presence of snow or the accretion of ice which could affect the wind action; - loads in areas where snow is present all year round; - lateral loading due to snow creep (e.g. lateral loads exerted by drifts); - loads due to artificial snow. 1.2 Assumptions The assumptions given in EN 1990:2023, 1.2 apply.

Hidrometrija. Bekontakčių metodų naudojimas tėkmės greičiui vandens paviršiuje matuoti ir debitui nustatyti (ISO/DIS 24577:2026)

Scope of the proposed deliverable To determine liquid flow, the following steps are necessary: 1) Measure water surface (or near surface) velocity with techniques using radar, laser or video images; 2) Adjust wind effects to the water surface velocity; 3) Translate the adjusted velocity to an averaged velocity by applying the velocity index or numerical computation; 4) Determine the area of the wetted cross section from the stage area relationship; and 5) Obtain water discharge by multiplying the averaged velocity by the wetted cross sectional area. This procedure is applicable to different kinds of channel and river section. Applications include: •Rivers and streams; •Artificial channels such as drainage ditches and irrigation channels; •Wastewater flows discharging to sewer or the environment through channels or partially filled pipes; •In sewer measurements; •Process flows on wastewater treatment plants. For any individual site the method to measure water surface velocity should be selected appropriately, based on the site conditions, nature of the application and uncertainty required. Take a special note that non-contact methods should NOT be used where a tidal phenomenon is present.

This document specifies the dimensions, the method of sampling, the preparation of the test specimens and the conditions for performing the tensile test in order to determine the short-term tensile welding factor. A tensile test can be used in conjunction with other tests (e.g. bend, tensile creep, macro) to assess the performance of welded assemblies, made from thermoplastics materials. The test is applicable to welded semi-finished products made from thermoplastics materials filled or unfilled, but not reinforced, irrespective of the welding process used.

Metalinės medžiagos. Bendrasis bandymo metodas kvazistatiniam atsparumui trūkimui nustatyti (ISO 12135:2021, įskaitant pataisytą 2022-08 versiją)

This document specifies methods for determining fracture toughness in terms of K, δ, J and R-curves for homogeneous metallic materials subjected to quasistatic loading. Specimens are notched, precracked by fatigue and tested under slowly increasing displacement. The fracture toughness is determined for individual specimens at or after the onset of ductile crack extension or at the onset of ductile crack instability or unstable crack extension. In cases where cracks grow in a stable manner under ductile tearing conditions, a resistance curve describing fracture toughness as a function of crack extension is measured. In some cases in the testing of ferritic materials, unstable crack extension can occur by cleavage or ductile crack initiation and growth, interrupted by cleavage extension. The fracture toughness at crack arrest is not covered by this document. Special testing requirements and analysis procedures are necessary when testing weldments, and these are described in ISO 15653 which is complementary to this document. Statistical variability of the results strongly depends on the fracture type, for instance, fracture toughness associated with cleavage fracture in ferritic steels can show large variation. For applications that require high reliability, a statistical approach can be used to quantify the variability in fracture toughness in the ductile-to-brittle transition region, such as that given in ASTM E1921. However, it is not the purpose of this document to specify the number of tests to be carried out nor how the results of the tests are to be applied or interpreted.

Plastikai. Būdingasis biologinis skaidumas. Kriterijai ir tyrimo metodai

This document defines test methods and criteria for distinguishing intrinsically biodegradable plastic materials from those that are persistent. Biodegradability is inferred from biodegradation tests conducted under aerobic conditions, i.e. under the conditions typically found in most natural habitats. Plastics that undergo ultimate biodegradation under aerobic conditions in a manner similar to natural polymer materials are defined as biodegradable plastics. This document describes a method for distinguishing between non-biodegradable plastics, which do not biodegrade even when environmental conditions are favourable for biodegradation (including aerobic conditions), and biodegradable plastics, i.e. those that biodegrade upon contact with active microorganisms when environmental conditions are favourable for biodegradation. The aim is to demonstrate ultimate aerobic biodegradability of plastic materials, i.e. the intrinsic potential for conversion to carbon dioxide, water and biomass by aerobic microorganisms in an oxygen-rich environment, which is representative of most natural environments. The potential for biodegradation should be verified using alternative tests and criteria, if a deposition in a permanent anaerobic environment (e.g. deep subsurface environments, wetlands and swamps, anoxic zones in oceans and lakes) is expected. NOTE Currently, there are no methodologies or criteria available to verify accumulation due to the lack of biodegradation of plastics in such anaerobic habitats. The plastic materials identified as intrinsically biodegradable following this document can be used in the design of products with a high risk of dispersion whenever the use of biodegradable components is searched by the designer. Intrinsically non-biodegradable components are not susceptible to biodegradation and therefore cannot be removed from the environment by the action of micro-organisms. This factor tends to increase the residence time of products in the environment. In addition, their eventual degradation, mainly due to abiotic factors, results in persistent fragments (microplastics). The test scheme described in this document is not specific to any particular application. Rather, it is a framework methodology that can be used in different industries to identify biodegradable plastics that can be used to make different types of products and for different applications. For the characterisation and environmental assessment of products placed on the market containing plastics identified as biodegradable according to this document, reference is made to the specific product standards, where available. This document only deals with the definition of intrinsic biodegradability of plastic materials, without defining the hazard of the products, which requires a specific assessment that is beyond the scope of this document. The rate of biodegradation of a plastic object as a function of environmental conditions cannot be determined from this document. Therefore, this document is not sufficient to carry out an analysis of the ecological risk associated with the dispersal of products, as this requires an assessment of the intrinsic hazard, of the environmental fate, in addition to the assessment of biodegradability. The methodology described in this document does not apply to applications covered by mandatory regulations.
