Įtaisai geriamajam vandeniui apsaugoti nuo taršos dėl atbulinio tekėjimo. Laisvasis išsiliejimas. A šeima. A tipas

This document specifies the characteristics and the requirements of unrestricted air gap Family A, Type A for nominal flow velocity not exceeding 3 m/s. Air gaps are devices for protection of potable water in water installations from pollution by backflow. This document applies to air gaps in factory-assembled products and to constructed air gaps in situ and specifies requirements and methods to verify and ensure compliance with this document during normal working use. The fluid in the receiving vessel is assumed to have similar properties to the water supply. Where this is not the case, additional care or tests could be required to verify the efficacy of the solution in practical use. The AA device is intended to be used in potable water installations according to EN 806 (series). Sanitary tapware when installed onto a receiving vessel (e.g. washbasin etc.) might have some restriction of its overflow. This will not compromise the water supply as the tapware might have an air gap, as detailed for example in EN 200 (dimension E), that provides an air gap disconnection. If this is the case, then backflow protection will be assumed to be adequate, and no further testing/verification will be needed.

Plastikai. Praskiestų polimerų tirpalų klampos nustatymas kapiliariniais viskozimetrais. 2 dalis. Polivinilchloridinės dervos (ISO/DIS 1628-2:2026)

1.1 This document specifies conditions for the determination of the reduced viscosity (also known as viscosity number) and K-value of PVC resins. It is applicable to resins in powder form which consist of homopolymers of the monomer vinyl chloride and copolymers, terpolymers, etc., of vinyl chloride with one or more other monomers, but where vinyl chloride is the main constituent. The resins can contain small amounts of unpolymerized substances (e.g. emulsifying or suspending agents, catalyst residues, etc.) and other substances added during the course of the polymerization. This document is not applicable, however, to resins having a volatile-matter content in excess of 0,5 % ± 0,1 %, when determined in accordance with ISO 1269:2006. In addition to this, it is not applicable to resins which are not entirely soluble in cyclohexanone. 1.2 The reduced viscosity and K-value of a particular resin are related to its molecular mass, but the relationship varies depending on the concentration and type(s) of other monomer(s) present. Hence, homopolymers and copolymers having the same reduced viscosity or K-value can have different molecular masses. 1.3 The values determined for reduced viscosity and K-value, for a particular sample of PVC resin, are influenced differently by the concentration of the solution chosen for the determination. Hence the use of the procedures specified in this document only gives values for reduced viscosity and K-value that are comparable when the concentrations of the solutions used are identical. 1.4 The experimental procedures specified in this document can also be used to characterize the polymeric fraction obtained during the chemical analysis of a PVC composition. However, the values calculated for the reduced viscosity and K-value in these circumstances can deviate form the correct values for the resin used to produce the composition because of the impure nature of the recovered polymer fraction.

Plastikai. Praskiesto polimerų tirpalo klampos nustatymas kapiliariniais viskozimetrais. 5 dalis. Termoplastinių poliesterių (TP) homopolimerai ir kopolimerai (ISO/DIS 1628-5:2026)

This part of ISO 1628 specifies a method for the determination of the viscosity number (also referred to as "reduced viscosity") of dilute solutions of thermoplastic polyesters (TPs) in certain specified solvents. The method is applicable to poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT), poly-(cyclohexylenedimethylene terephthalate) (PCT), and poly(ethylene naphthalate) (PEN), as well as to copolyesters and other polyesters, referred to in ISO 20028-1:2019, that are soluble in one of the specified solvents under the specified conditions. The viscosity number is determined by the general procedure specified in ISO 1628-1:2024, observing the particular conditions specified in this part of ISO 1628. The determination of the viscosity number of a thermoplastic polyester provides a measure of the relative molecular mass of the polymer.

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).

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.
