This document specifies a method for the determination of the kinematic viscosity of bituminous binders at 60 °C and 135 °C, in a range from 6 mm2/s to 300 000 mm2/s. Other temperatures are possible if calibration constants are known. Bituminous emulsions are not covered within the scope of this method. Results for this method can be used to calculate dynamic viscosity when the density of the test material is known or can be determined. 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 identify the hazards and assess the risks involved in performing this test method and to implement sufficient control measures to protect individual operators (and the environment). This includes appropriate safety and health practices and determination of the applicability of regulatory limitations prior to use.

This document specifies the additional characteristics for the adhesives for ceramic tiles, i.e. cementitious ones for internal and external tile installations, dispersion and reaction resin ones for internal tile installations, on walls and floors. This document provides the terminology concerning the products, working methods, application properties, etc., for ceramic tile adhesives. This document does not provide criteria or recommendations for the design and installation of ceramic tiles. NOTE Ceramic tile adhesives are also used for other types of tiles (natural and agglomerated stones, etc.), if they do not adversely affect these materials.

This document specifies the terms, definitions, test conditions, test methods and requirements for rating the performance of air conditioners and liquid chilling packages, with electrically driven compressors and with evaporatively cooled condenser when used for space cooling. The evaporatively cooled condenser is cooled by air and by the evaporation of external additional water. This additional external water is fed by a specific water supply circuit or by a water tank. This document does not apply to air-to-air and air-to-water air conditioners with a condenser cooled by air and by the evaporation of water condensed on their evaporator. This document applies to units equipped with a water tank or with a continuous water circuit supply that can also operate without water feeding. However, this document only concerns the testing of these units with water feeding. This document applies to factory-made units which can be ducted. This document applies to factory-made units of either fixed capacity or variable capacity by any means. Packaged units, single split and multisplit systems are covered by this document. With regard to units consisting of several parts, this document applies only to those designed and supplied as a complete package. For evaporatively cooled condenser units that can also operate in heating mode, their performance in this mode is determined according to EN 14511 (all parts). Installations used for industrial processes cooling are not within the scope of this document. This document specifies the conditions for which performance data will be declared for compliance to the Ecodesign Regulation 206/2012 and to the Energy Labelling Regulation 626/2011 of air conditioners with evaporatively cooled condenser in cooling mode. NOTE All the symbols given in this text can be used regardless of language.

This document specifies the characteristics and performance for design External Thermal Insulation Composite Systems (design ETICS) with rendering systems on thermal insulation products, delivered as a kit by a system holder, and used as thermal insulation for buildings. This document covers design ETICS kits on walls which are made of masonry (bricks, blocks, stones, etc.) or concrete (cast on site or as prefabricated panels) with or without rendering systems. This document covers ETICS with thermal insulation products made of cellular glass, expanded polystyrene, expanded cork, mineral wool, phenolic foam, rigid polyurethane foam, extruded polystyrene foam or wood fibre as far as they comply with Annex B. A design ETICS kit comprises a prefabricated insulation product bonded onto the wall, or mechanically fixed using anchors, profiles, etc., or a combination of adhesive and mechanical fixings. The insulation product is faced with a rendering system consisting of one or more layers (site applied), one of which contains reinforcement. The rendering system is applied directly to the insulating panels, without an air gap or disconnecting layer. This document is not applicable for: a) Mechanically fixed kits with supplementary adhesive with the mass per unit area of the rendering system of > 40 kg/m2 in end use conditions intended by the system holder and/or mechanical fixed kits with the mass per unit area of the rendering system plus thermal insulation product of > 65 kg/m2 intended by the system holder. b) Mechanically fixed kits without supplementary adhesive with the mass per unit area of the rendering system of > 30 kg/m2 in end use conditions intended by the system holder and/or mechanical fixed kits with the mass per unit area of the rendering system plus thermal insulation product of > 60 kg/m2 intended by the system holder and/or with a thickness of the thermal insulation product intended by the system holder of > 200 mm. For thermal insulations products with thicknesses ≤ 200 mm fixed with anchors without supplementary adhesive, the bending deformation of the mechanically fixing devices is assumed as negligible. c) Purely bonded kits with or without supplementary mechanically fixing devices with bonded area (coverage) less than 40 %, intended by the system holder. d) Mechanically fixed kits with supplementary adhesive with bonded area (coverage) less than 40 %, intended by the system holder. e) Kits incorporating a thermal insulation product providing a declared thermal resistance of less than 1 m2K/W. External insulation and finishing systems (EIFS) according to ISO 17738 are not covered by this standard.
