Fenoliniai ir aminoplastiniai laikančiųjų medinių konstrukcijų klijai. Klasifikavimas ir eksploatacinių charakteristikų reikalavimai

This document establishes a classification for phenolic and aminoplastic polycondensation adhesives according to their suitability for use for load-bearing timber products in defined climatic exposure conditions, and specifies performance requirements for such adhesives for the factory manufacture or factory-like manufacturing conditions of load-bearing timber products only. 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) or the production of wood-based panels, except solid wood panels, or modified and stabilized wood with considerably reduced swelling and shrinkage properties, e.g. acetylated wood, heat treated wood and polymer impregnated wood. This document is primarily intended for use by adhesive manufacturers and for use in timber products bonded with adhesives, to assess or control the quality of adhesives. The requirements are applicable 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 load-bearing timber products, provided that the bonding process has been carried out according to an appropriate product standard.

This document describes the reference methods for the determination of swelling, swelling pressure, magnitude or potential of one-dimensional swelling of a soil when subjected, in the presence of water, to vertical stresses under oedometric conditions. It is used to assess the behaviour of earthwork platform that may be affected by the presence of swelling soils. These methods are used to determine three parameters related with the swelling of a soil: the swelling pressure, the swelling index and the constrained swelling pressure. These test methods specify the technique for specimen preparation, apparatus and procedure for quantifying the amount of height change associated with swelling and procedures for reporting test results. The procedures given in these test methods are applicable to undisturbed, remoulded, recompacted or reconstituted specimens.

This document is part of a System Standard for plastics piping systems of a particular material for a specified application. There are a number of such System Standards. System Standards are based on the results of the work being undertaken in ISO/TC 138 “Plastics pipes, fittings and valves for the transport of fluids”, which is a Technical Committee of the International Organization for Standardization (ISO). They are supported by separate standards on test methods, to which references are made throughout the System Standard. The System Standards are consistent with general standards on functional requirements and on recommended practice for installation. This document specifies the definitions and requirements for unplasticized polyvinyl chloride (PVC-U), polypropylene (PP) and polyethylene (PE) ancillary fittings and shallow chambers intended for use in non-pressure underground drains and sewers for wastewater. This document is applicable to: a) ancillary fittings and shallow chambers, intended for use buried underground outside the building structure; reflected in the marking of products by "U"; b) ancillary fittings and shallow chambers, intended for use buried underground both outside (application area code “U”) and within the building structure, reflected in the marking of products by "UD". This document also covers the jointing of the ancillary fittings and shallow chambers to the piping system. The document is applicable to the following ancillary fittings: - sealed access fittings; - rodding point covers; - rodding tees; - mechanical saddles. Ancillary fittings according to this document are intended for use in pedestrian areas, except rodding tees and mechanical saddles which can also be used in vehicular trafficked areas. Ancillary fittings can be installed to a maximum depth of 6,0 m from ground level, with the exception of rodding point covers with a maximum depth of 2,0 m. Shallow chambers according to this document are intended for use in private drains located in pedestrian areas above the ground water table, to a maximum depth of 2,0 m from ground level to the invert of the main flow channel. This document covers shallow chambers having a base with a flow channel and their joints to the piping system. Ancillary fittings and shallow chambers can be manufactured by various methods e.g. injection moulding, rotational moulding, spiral winding or fabricated. NOTE 1 Products complying with this document can be used with pipes, fittings and other components conforming to any of the plastics products standards listed in Annex E, providing their dimensions are compatible. NOTE 2 Products complying with this document can be installed in underground applications without additional static calculation. prEN 13598-1:2025 (E) 6 NOTE 3 Ancillary fittings and shallow chambers can be subject to national regulations and / or local provisions.
