Bituminous mixtures - Test methods - Part 10: Compactability

This document describes three test methods for characterizing the compactability of a bituminous mix, by the relation between its density or void content and the compaction energy applied to it, using an impact (Marshall) compactor, gyratory compactor, or a vibratory compactor. This document applies to bituminous mixtures, both those prepared in laboratory and those resulting sampled from plant produced mixtures. The results of the test method serve to supplement the results of mixture design.

Preparation of steel substrates before application of paints and related products - Specifications for non-metallic blast-cleaning abrasives - Part 10: Almandite garnet (ISO/DIS 11126-10:2025)

ISO 11126-10:2017 specifies requirements for almandite garnet abrasives, as supplied for blast-cleaning. It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in ISO 11126-10:2017 apply to abrasives supplied in the "new" condition only. They do not apply to abrasives either during or after use. Test methods for non-metallic blast-cleaning abrasives are given in the various parts of ISO 11127. NOTE Although ISO 11126-10:2017 has been developed specifically to meet requirements for preparation of steelwork, the properties specified are generally appropriate for use when preparing other material surfaces, or components, using blast- cleaning techniques. These techniques are described in ISO 8504‑2.

Fire resistance tests for non-loadbearing elements - Part 4: Curtain walling - Part configuration

This document specifies a method for determining the fire resistance of parts of curtain walling and of the perimeter seal. It examines the fire resistance to internal and external fire exposure of: - the spandrel panel, i.e. downstand, upstand or a combination thereof; - the perimeter seal; - the fixing of the framing system (anchoring) used to attach the curtain walling to the floor element; - combinations thereof. NOTE 1 This document does not test fire spread that can be caused through cavities in the test specimen, i.e., inside of the mullions (see note to 9.1.2.3.3). Results from tests according to this document form the basis for classification of curtain walling type A (see 3.3 for definition). For curtain walling type B (see 3.4 for definition) results can be used to determine fire resistance of parts of a curtain walling to increase the field of application when previously tested to EN 1364-3. For intended classification EW and for corner/faceted specimens EN 1364-3 can be used. This document does not cover double skin façades, over-cladding systems and ventilated façade systems on external walls. It does not deal with the reaction to fire behaviour of curtain walling. This document is intended to be read in conjunction with EN 1363-1 and EN 1363-2 as well as EN 1364-3 for curtain walling type B. As per the type of curtain walling covered by this document, these are the ones included in EN 13119. NOTE 2 Annex A gives informative guidance on the principles of testing parts of curtain walling and the test method. NOTE 3 When tests are made to examine single elements (e.g. perimeter seal), those elements are to be installed as part of a curtain walling system.

Numerical welding simulation - Execution and documentation (ISO/DIS 18166:2025)

ISO/TS 18166:2016 provides a workflow for the execution, validation, verification and documentation of a numerical welding simulation within the field of computational welding mechanics (CWM). As such, it primarily addresses thermal and mechanical finite element analysis (FEA) of the fusion welding (see ISO/TR 25901:2007, 2.165) of metal parts and fabrications. CWM is a broad and growing area of engineering analysis. ISO/TS 18166:2016 covers the following aspects and results of CWM, excluding simulation of the process itself: - heat flow during the analysis of one or more passes; - thermal expansion as a result of the heat flow; - thermal stresses; - development of inelastic strains; - effect of temperature on material properties; - predictions of residual stress distributions; - predictions of welding distortion. ISO/TS 18166:2016 refers to the following physical effects, but these are not covered in depth: - physics of the heat source (e.g. laser or welding arc); - physics of the melt pool (and key hole for power beam welds); - creation and retention of non-equilibrium solid phases; - solution and precipitation of second phase particles; - effect of microstructure on material properties. The guidance given by this Technical Specification has not been prepared for use in a specific industry. CWM can be beneficial in design and assessment of a wide range of components. It is anticipated that it will enable industrial bodies or companies to define required levels of CWM for specific applications. This Technical Specification is independent of the software and implementation, and therefore is not restricted to FEA, or to any particular industry. It provides a consistent framework for-primary aspects of the commonly adopted methods and goals of CWM (including validation and verification to allow an objective judgment of simulation results). Through presentation and description of the minimal required aspects of a complete numerical welding simulation, an introduction to computational welding mechanics (CWM) is also provided. (Examples are provided to illustrate the application of this Technical Specification, which can further aid those interested in developing CWM competency). Clause 4 of this Technical Specification provides more detailed information relating to the generally valid simulation structure and to the corresponding application. Clause 5 refers to corresponding parts of this Technical Specification in which the structure for the respective application cases is put in concrete terms and examples are given. Annex A presents a documentation template to promote the consistency of the reported simulation results.
