Konstrukcijų klijai. Daugiakomponenčių klijų tinkamumo trukmės nustatymas (ISO 10364:2024)

This document specifies methods for determining the pot life of multi-part adhesives, in order to be able to determine whether the pot life conforms to the minimum specified working life required of an adhesive. The different methods described in this document to measure the property do not necessarily provide identical results. The test methods described are suitable for assessing all multi–part adhesives, and especially epoxy based and polyurethane based adhesives, but they are not suitable for some acrylic-based adhesives. NOTE 1 Some of the methods described in this document can also be suitable for determination of working life of one-part adhesives that react to humidity (e.g. PUR prepolymers). NOTE 2 This document can also be used for assessing non-structural adhesives.

Klijai. Cementinių ir kalcio sulfato grindų išlyginimo mišinių bandymo metodas. Sukibimo stiprio nustatymas

This document specifies a test method for the determination of bond strength between an underlayment produced with cementitious or calciumsulfate-based floor levelling compounds and a standard substrate. This document applies to cementitious, and calcium sulphate-based floor levelling compounds used for the preparation of subfloors to ensure the suitability of the substrate prior to the installation of floor coverings. By using the floor levelling compound, a homogeneous layer is built up on the load-bearing substrate, to ensure consistent absorbency, evenness and strength.

Klijai. Cementinių ir kalcio sulfato grindų išlyginimo mišinių bandymo metodas. Traukimosi nustatymas

This document specifies the measurement of dimensional change of set cementitious and calcium sulfate-based floor levelling compounds after mixing with a liquid, e.g. water. This document applies to cementitious and calcium sulfate-based floor levelling compounds used for the preparation of subfloors to ensure the suitability of the substrate prior to the installation of floor coverings. By using the floor levelling compound, a homogeneous layer is built up on the load-bearing substrate, to ensure consistent absorbency, evenness and strength.

Klijai. Cementinių ir kalcio sulfato grindų išlyginimo mišinių bandymo metodas. Standartinės maišymo procedūros

This document specifies the procedure for mixing cementitious and calcium sulfate-based floor levelling compounds with water and/or a liquid component as supplied by the manufacturer. This document applies to cementitious, and calcium sulfate-based floor levelling compounds used for the preparation of subfloors to ensure the suitability of the substrate prior to the installation of floor coverings. By using the floor levelling compound, a homogeneous layer is built up on the load-bearing substrate, to ensure consistent absorbency, evenness and strength.

Klijai. Cementinių ir kalcio sulfato grindų išlyginimo mišinių bandymo metodas. Kietėjimo trukmės nustatymas

This document specifies the measurement of setting time of a prepared cementitious or calcium sulfate-based floor levelling compound, after mixing with the liquid component, e.g. water. This document applies to cementitious and calcium sulfate-based floor levelling compounds used for the preparation of subfloors to ensure the suitability of the substrate prior to the installation of floor coverings. By using the floor levelling compound, a homogeneous layer is built up on the load-bearing substrate, to ensure consistent absorbency, evenness and strength.

Iš lapuočių medienos gaminamų laikančiųjų medinių konstrukcijų klijai. Klasifikavimas ir eksploatacinių charakteristikų reikalavimai. 1 dalis. Tam tikrų lapuočių rūšių medienos klijai (A grupė), be specialaus klasifikavimo pagal didelį atsparumą šlyčiai

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.
