Statybinis stiklas. Šilumos perdavimo koeficiento (U vertės) nustatymas. Skaičiavimo metodas

This document specifies a calculation method to determine the thermal transmittance of glass with flat and parallel surfaces. This document applies to uncoated glass (including glass with structured surfaces, e.g. patterned glass), coated glass and materials not transparent in the far infrared which is the case for soda lime glass products, borosilicate glass, glass ceramic, alkaline earth silicate glass and alumino silicate glass. It applies also to multiple glazing comprising such glasses and/or materials. It does not apply to multiple glazing which include in the gas space sheets or foils that are far infrared transparent. The procedure specified in this document determines the U value (thermal transmittance) in the central area of glazing. The edge effects due to the thermal bridge through the spacer of an insulating glass unit or through the window frame are not included. Furthermore, energy transfer due to solar radiation is not taken into account. The effects of Georgian and other bars are excluded from the scope of this document. NOTE EN ISO 10077 1:2017 provides a methodology for calculating the overall U value of windows, doors and shutters [1], taking account of the U value calculated for the glass components according to this document. Also excluded from the calculation methodology are any effects due to gases that absorb infrared radiation in the 5 to 50 µm range. The primary purpose of this document is product comparison, for which a vertical position of the glazing is specified. In addition, U values are calculated using the same procedure for other purposes, in particular for predicting: - heat loss through glass; - conduction heat gains in summer; - condensation on glass surfaces; - the effect of the absorbed solar radiation in determining the solar factor [2]. Reference can be made to [3], [4] and [5] or other European Standards dealing with heat loss calculations for the application of glazing U values determined by this standard. Reference can be made to [6] for detailed calculations of U values of glazing, including shading devices. Vacuum Insulating Glass (VIG) is excluded from the scope of this document. For determination of the U value of VIG, please refer to EN 674 or ISO 19916-1. A procedure for the determination of emissivity is given in EN 12898. The rules have been made as simple as possible consistent with accuracy.

Naftos ir gamtinių dujų pramonė. Transportavimo vamzdynais sistemos. Vamzdynų su plieniniais gaubtais projektavimas, įrengimas ir priežiūra (ISO/DIS 16440:2025)

ISO 16440:2016 specifies requirements, including corrosion protection, for the design, fabrication, installation and maintenance of steel-cased pipelines for pipeline transportation systems in the petroleum and natural gas industries in accordance with ISO 13623. NOTE 1 Steel casings can be used for mechanical protection of pipelines at crossings, such as at roads and railways and the installation of a casing at a highway, railway, or other crossing can be required by the permitting agency or pipeline operator. NOTE 2 This document does not imply that utilization of casings is mandatory or necessary. NOTE 3 This document does not imply that cased crossings, whether electrically isolated or electrically shorted, contribute to corrosion of a carrier pipe within a cased crossing. However, cased crossings can adversely affect the integrity of the carrier pipe by shielding cathodic protection (CP) current to the carrier pipe or reducing the CP effectiveness on the carrier pipe in the vicinity of the casing. Their use is not recommended unless required by load considerations, unstable soil conditions, or when their use is dictated by sound engineering practices.

This document establishes a classification for phenolic and aminoplastic polycondensation adhesives classified according to EN 301, one component polyurethane adhesives classified according to EN 15425 and emulsion polymer isocyanate adhesives classified according to EN 16254, according to their suitability for use for load-bearing timber structures made of selected hardwood species (group A) in defined climatic exposure conditions; it specifies performance requirements for such adhesives for the factory manufacture or factory-like manufacturing conditions of load-bearing timber structures made of selected hardwood species only, with no specific high shear strength classification. NOTE An adhesive with high shear strength classification is needed when the declared characteristic shear strength of the glued laminated product is above 3,5 N/mm2, which is the declared characteristic shear strength of glulam made of softwoods according to EN 14080:2013 Table 4. See prEN 18307-3 requirements in this case. It also classifies aminoplastic adhesive systems being used with a range of hardener dosage, and one component polyurethane adhesive product lines where all the products within the line have the same chemical composition except for a different amount of catalyst. This document only specifies the performance of an adhesive for use in an environment corresponding to the defined conditions. The performance requirements of this document are applicable to the adhesive only, not to the manufacturing timber products. This document does not cover the performance of adhesives for on-site gluing (except for factory-like conditions) nor the production of wood-based panels, except solid wood panels, or modified and stabilized wood with considerably reduced swelling and shrinkage properties, e.g. such as acetylated wood, heat treated wood and polymer impregnated wood. It also does not cover preservative treated wood. This document is primarily intended for use by adhesive manufacturers and for use in timber products made of selected hardwood species bonded with adhesives, to assess or control the quality of adhesives. The requirements apply to the type testing of the adhesives. Production control activities are outside the scope of this document. Adhesives meeting the requirements of this document are adequate for use in a load-bearing timber products made of selected hardwood species, provided that the bonding process has been carried out according to an appropriate product standard. Selected hardwood species covered by this document are listed in FprCEN/TS XXX , group A. FprCEN/TS XXX also specifies nominal physical properties of the mentioned species that are used for testing according to this document.

ISO 23146:2012 specifies a method for the determination of the fracture toughness of advanced technical ceramics. The procedure makes use of single-edge V-notched bars, which are loaded in four-point bending until failure. It is applicable to monolithic ceramics with a grain size or major microstructural feature size larger than about 1 µm. The use of ISO 23146:2012 for yttria tetragonal zirconia polycrystal material (Y-TZP) is not recommended. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch.
