prEN ISO 472-3 Viešoji apklausa

Komentavimo iki data 2026-12-12

Plastikai. Aiškinamasis žodynas. 3 dalis. Plastikų suvirinimas ir šiluminis sujungimas (ISO/DIS 472‑3:2026)

The ISO 472 series defines terms used in the plastics industry, including terms and definitions appearing in the plastics standards of ISO/TC 61 and general terms and definitions of polymer science used in all aspects of plastics technology. This document defines terms used in the plastics standards of ISO TC61/SC11 Plastics Products and relevant terms applied in the area of welding (including solvent welding) and thermal staking.

prEN ISO 527-6 Viešoji apklausa

Komentavimo iki data 2026-12-06

Plastikai. Tempimo savybių nustatymas. 6 dalis. Atsitiktine tvarka orientuotomis kapotomis sluoksnelėmis arba stiklo pluoštu armuotų plastikų kompozitų deformacijų pasiskirstymo matavimas (ISO/DIS 527-6:2026)

This document outlines methods for measuring the strain distribution for randomly oriented chopped strand- or fibre-reinforced plastic composites, based upon the general principles given in ISO 527-4. The methods are used to statistically evaluate the inherent variation of strain-based properties. The main purpose of this document compared to existing standards is to evaluate the strain distribution due to the random orientation of chopped fibres, while ISO 527-4 is sufficient for evaluating only the bulk elastic modulus. This standard provides two methods for evaluating an inherent strain distribution of the material, Method A as using DIC analysis system and Method B as using several strain gauges with a short gauge length. The methods are suitable for use with fibre-reinforced thermosetting and thermoplastic composites incorporating discontinuous or chopped reinforcements such as mats, chopped strands or tapes, long-fibre injection or combination of such reinforcements. The methods are not normally suitable for continuous fibre-reinforced materials which generate homogeneous strain distribution on the surface of the test specimen.

prEN 12814-3 Viešoji apklausa

Komentavimo iki data 2026-12-06

Termoplastikinių pusgaminių suvirintųjų jungčių bandymai. 3 dalis. Tempiamojo valkšnumo bandymas

This document specifies the dimensions, the method of sampling, the preparation of the test specimens and the conditions for performing the tensile creep test perpendicular to the weld in order to determine the long-term tensile welding factor. A tensile creep test may be used in conjunction with other tests (e.g. bend test, tensile test, macrographic examination, …) to assess the performance of welded assemblies made from thermoplastics materials. The test is applicable to welded assemblies made from thermoplastics materials, filled or unfilled such as tubes and fittings, sheets, plates and profiles, but not reinforced, irrespective of the welding process used.

prEN ISO 21304-2 Viešoji apklausa

Komentavimo iki data 2026-12-05

Plastikai. Ypač didelės molekulinės masės polietileno (PE-UHMW) liejimo ir ekstruzijos medžiagos. 2 dalis. Bandinių paruošimas ir savybių nustatymas (ISO/DIS 21304-2:2026)

This document specifies the methods of preparation of test specimens and the test methods to be used for determining the properties of ultra-high-molecular-weight polyethylene (PE-UHMW) moulding and extrusion materials. It establishes general principles for handling test materials and for conditioning both the test materials before moulding and the specimens before testing. This document specifies procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made. Properties and test methods which are suitable and necessary to characterize PE-UHMW moulding and extrusion materials are established. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this document, as are the designatory properties specified in ISO 21304-1. This document specifies the-materials with MFR less than 0,1 g/10 min at 190 °C /21,6 kg based on ISO 17855-1. The methods of preparation and conditioning, the specimen dimensions and the test procedures specified in this document are used in order to obtain reproducible and comparable test results. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

prEN 438-2 Viešoji apklausa

Komentavimo iki data 2026-11-30

Didelio slėgio apdailos laminatai (HPL). Lakštai termoreaktyviųjų dervų pagrindu (paprastai vadinami laminatais). 2 dalis. Savybių nustatymas

This document specifies the methods of test for determination of the properties of high-pressure decorative laminates as defined in Clause 3. These methods are primarily intended for testing the sheets specified in EN 438-3, EN 438-4, EN 438-5, EN 438-6, EN 438-8, and EN 438-9. The precision of the test methods, specified in this document, is not known because inter-laboratory data are not yet available. When inter-laboratory data will be obtained, precision statements will be added to the test method at the following revision. For those test methods having an end point determination based on subjective judgement, it is not meaningful to make a statement of precision.

prEN ISO 11403-3 Viešoji apklausa

Komentavimo iki data 2026-11-15

Plastikai. Lyginamųjų daugiataškių duomenų rinkimas ir pateikimas. 3 dalis. Aplinkos poveikis savybėms (ISO/DIS 11403-3:2026)

This document specifies test procedures for the acquisition and presentation of multipoint data which demonstrate the behaviour of plastics under the following environments: — prolonged exposure to heat; — liquid chemicals; — environmental stress cracking under a constant tensile stress; — artificial weathering. The tests are listed in order of increasing severity of the environment. By testing under the least severe environments first, it is possible to make informed judgements regarding whether tests under more severe conditions are worthwhile.
