Bitumas ir bituminiai rišikliai. Kompleksinio šlyties modulio ir fazės kampo nustatymas. Dinaminis šlyties reometras (DSR)

This document specifies a general method of using a dynamic shear rheometer (DSR) for measuring the rheological properties of bituminous binders. The procedure involves determining the complex shear modulus and phase angle of binders over a range of test frequencies and test temperatures when tested in oscillatory shear. From the test, the complex shear modulus, |G*|, and its phase angle, δ, at a given temperature and frequency are calculated, as well as the components G' and G" of the complex shear modulus. This method is applicable to un-aged, aged, stabilized and recovered bituminous binders. The test procedure in accordance with this document is not applicable for bituminous binders with particles larger than 250 μm (e.g. filler material, granulated rubber). WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

Eurokodas 8. Atsparių žemės drebėjimui konstrukcijų projektavimas. 3 dalis. Pastatų ir tiltų vertinimas ir rekonstrukcija

1.1 Scope of EN 1998-3 (1) This document is applicable to the assessment and retrofitting of buildings and bridges in seismic regions, namely as given in a) to c): a) to provide criteria for the assessment of the seismic performance of existing individual buildings and bridges; b) to describe the procedure to be followed in selecting necessary corrective measures; c) to set forth criteria for the design of retrofitting measures (i.e. design, structural analysis including intervention measures, final dimensioning of structural parts and their connections to existing structural members). NOTE 1 For the purposes of this document, retrofitting covers both the seismic upgrading (e.g. strengthening or adding a passive system) of undamaged structures and the repair and possible upgrading of earthquake-damaged structures. NOTE 2 Only the most common retrofit techniques are covered in this document. This does not exclude the use of other techniques, which can be developed in each country, based on the strengthening principles of this document. NOTE 3 Annex D gives flowcharts for the application of this document. (2) Unless specifically stated, EN 1998-1-1 and EN 1998-5 apply. (3) Reflecting the performance requirements of EN 1998-1-1:2024, 4.1, this document covers the seismic assessment and retrofitting of buildings and bridges made of the more commonly used structural materials: concrete, steel and composite, timber and masonry. NOTE Annexes B and C contain additional guidance related to the assessment of timber and masonry structures, respectively, and to their retrofitting when necessary. (4) This document is intended for the assessment of individual structures, to decide on the need for structural intervention and to design the retrofitting measures that may be necessary. It is not intended for the vulnerability assessment of populations or groups of structures in seismic risk evaluations for various purposes (e.g. for determining insurance risk, for setting risk mitigation priorities, etc.). (5) This document provides (in its material-specific Clauses 8 to 11) criteria for the verification of the more common retrofitting techniques currently in use. (6) This document gives specific rules for the assessment and retrofitting relevant to existing buildings and bridges of consequence classes CC1, CC2 and CC3, as defined in EN 1990:2023, 4.3. (7) Although the provisions of this document are applicable to all common categories of buildings and bridges, the seismic assessment and retrofitting of monuments and heritage structures often requires different types of provisions and approaches, depending on the nature of the monuments and heritage structures. 1.2 Assumptions (1) The assumptions of EN 1998-1-1 apply to this document. (2) The provisions of this document assume that the data collection and tests are performed by experienced personnel and that the engineer responsible for the assessment, the possible design of the retrofitting and the execution of work has appropriate experience of the type of structures being upgraded or repaired. (3) It is assumed that inspection procedures, checklists and other data-collection procedures will be documented and filed and referred to in the assessment/design documents.

Traukos spintos. 9 dalis. Vėdinamosios traukos spintos su filtruojamąja vidine recirkuliacija

This document specifies characteristics concerning the design and performance requirements together with type testing and on-site testing procedures especially for ducted filtration fume cupboards (DFFCs) not described in the other parts of EN 14175. Filters in DFFCs can be specific filters or a combination of filters dependent on the characteristics of the contaminants to be removed. This part of EN 14175 is related to and refers to other parts of EN 14175 regarding definitions, technologies, testing methodologies, design factors and functional aspects and is read in conjunction with these. This standard covers the specific layout version of ducted fume cupboards with integral filtration. These devices called ducted filtration fume cupboards can be designed to partially reuse filtered air for internal dilution. Therefore, the term “hybrid” fume cupboards is sometimes used. Fume cupboards with associated filters are considered as standard fume cupboards according EN 14175 1 to EN 14175 3. NOTE Their filter requirements, description and testing are listed in Annex A for information. The requirements for fume cupboards and filters for radioactive work are described in detail in EN 14175 8. Recirculatory filtration fume cabinets which return the filtered exhaust air back into the surrounding room are not part of this document but described in prEN 17242. DFFCs are not foreseen for work with pathogens. Appropriate microbiological cabinets are described in the EN 12469 series.

This document describes procedures for the testing of dyed paper and board intended to come into contact with foodstuffs. Some procedures depending on the foreseeable use of the material are given. Visual evaluation against a grey scale provides grading of the bleeding. For samples having significant different sides, a migration can occur from one glass fibre to the other and could lead to wrong interpretation of the fastness of one side. It is advisable to check these samples using large sampling procedure to prevent cross contamination of the glass fibre during the migration procedure. The procedure is described in Annex A. If lower limit of detection is required, this procedure could also be used.
