Vandenilio technologijos. Šiltnamio efektą sukeliančių dujų kiekio, susijusio su vandenilio tiekimo grandine, nustatymo metodika. 1 dalis. Išmetamas kiekis, susijęs su vandenilio gamyba visame gamybos etape (ISO/DIS 19870-1:2025)

ISO 14044 requires the goal and scope of an LCA to be clearly defined and be consistent with the intended application. Due to the iterative nature of LCA, it is possible that the LCA scope needs to be refined during the study. This document specifies methodologies that can be applied to determine the carbon footprint of a product (CFP) or partial CFP of a hydrogen product in line with ISO 14067. The goals and scopes of the methodologies correspond to either approach a) or b), given below, that ISO 14040:2006, A.2 gives as two possible approaches to LCA. a) An approach that assigns elementary flows and potential environmental impacts to a specific product system, typically as an account of the history of the product. b) An approach that studies the environmental consequences of possible (future) changes between alternative product systems. Approaches a) and b) have become known as attributional and consequential, respectively, with complementary information accessible in the ILCD handbook.[1] There are numerous pathways to produce hydrogen from various primary energy sources. This document describes the requirements and evaluation methods applied to several hydrogen production pathways of interest: electrolysis, steam methane reforming (with carbon capture and storage), co-production and coal gasification (with carbon capture and storage), auto-thermal reforming (with carbon capture and storage), hydrogen as a co-product in industrial applications and hydrogen from biomass waste as feedstock. This document also considers the GHG emissions due to the conditioning or conversion of hydrogen into different physical forms and chemical carriers: — hydrogen liquefaction; — production, transport and cracking of ammonia as a hydrogen carrier; — hydrogenation, transport and dehydrogenation of liquid organic hydrogen carriers (LOHCs). This document considers the GHG emissions due to hydrogen and/or hydrogen carriers’ transport up to the consumption gate. It is possible that future revisions of this document will consider additional hydrogen production, conditioning, conversion and transport methods. This document applies to and includes every delivery along the supply chain up to the final delivery to the consumption gate (see Figure 2 in the Introduction). This document also provides additional information related to evaluation principles, system boundaries and expected reported metrics in the form of Annexes A to K, that are accessible via the online ISO portal (https://standards.iso.org/iso/ts/19870/ed-1/en).

Ištisine lydaline danga dengti plokštieji plieniniai gaminiai, skirti šaltajam formavimui. Techninės tiekimo sąlygos

This document specifies requirements for continuously hot-dip coated products made of low carbon steels for cold forming, of steels for construction and of steels with high proof strength for cold forming coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA), zinc-magnesium alloy (ZM), aluminium-silicon alloy (AS) or aluminium (A) and for continuously hot-dip coated products made of multiphase steels for cold forming coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA) or zinc-magnesium alloy (ZM) in thicknesses of 0,20 mm ≤ t ≤ 6,5 mm. By agreement at the time of enquiry and order, this document is applicable to continuously hot-dip coated flat products of an expanded validity range defined for thicknesses t < 0,20 mm with agreed mechanical properties and test specimens, adhesion of coating and surface condition requirements. This document applies to strip of all widths and to sheets cut from it (≥600 mm width) and cut lengths (<600 mm width). NOTE The products covered by this document are used where cold formability, high strength, a defined minimum yield strength and/or corrosion resistance are the most important factors. Corrosion resistance of the product is depending on coating type and coating thickness, hence to its mass (see also 7.3.2). The products covered by this document can be used as substrates for organic coated flat products specified in EN 10169 for building and general engineering applications.

Specialiųjų geotechnikos darbų atlikimas. Grunto maišymas vietoje

This document specifies general principles for the execution, supervision, inspection, testing and monitoring of in situ soil mixing works (Deep Mixing) carried out by two different methods: dry mixing and wet mixing. Soil mixing considered in this document is limited to methods which involve: - mixing by rotating mechanical mixing tools, including jetting and/or compressed air assistance, where the lateral support provided by the surrounding ground is not removed; - different shapes and configurations of soil mixing elements, either columns, panels, walls or any combination of more than one single element, with or without overlapping; - treatment of soils and fills, including brownfields, sludges, etc., with possible limited penetration into the rock; - mass mixing; - environmental mixing, involving installation of containment and permeable reactive barriers and solidification/stabilization of contaminated soils and sludges. This standard does not apply to shallow soil stabilization, which consists of granulating the surface soil and mixing it with binder using soil stabilizing machines to improve soil performance as an alternative to soil replacement, typically in road works.

Pigmentai ir užpildai. Dispergavimo procedūra sedimentacija pagrįstam skendinčių pigmentų ar užpildų dalelių dydžio nustatymui taikant sedimentacijos skystyje metodus (ISO/DIS 20427:2025)

This document specifies sample preparation methods to determine the size distribution of separate particles of a single pigment or extender, which is dispersed in a liquid by application of a standardized dispersion procedure, using an ultrasonic device, shaker device or wet jet mill. The sample preparation methods described are optimized for measurements carried out with a particle sizing technique based on sedimentation. This technique relies on particle migration due to gravitation or centrifugal forces and requires a density contrast between the particles and the liquid phase.
