This document specifies the general principles to be followed when test specimens of thermoplastic materials are prepared by laser-based powder bed fusion, which is also called laser sintering. The laser-sintering process is used to prepare specimens layer upon layer in which thermal energy selectively fuses regions of a powder bed. This document provides a basis for establishing reproducible sintering conditions. Its purpose is to promote uniformity in describing the main process parameters, build orientation of the sintering process and also to establish uniform practice in reporting sintering conditions.The particular conditions required for reproducible preparation of test specimens which will give comparable results will vary for each material used. These conditions shall be agreed upon between the interested parties.

This document applies to electronic control equipment for heating systems with direct electrical emission, which have an integrated outside compensated function and or optimum start/stop function.This control equipment controls the distribution and/or the generation of heat in relation to the outside temperature and time and other reference variables.This document also covers controllers that contain an integrated optimum start or an optimum start-stop control function. The controller modulates heating or control modes of electronic individual zone or emitter control equipment.Safety requirements on heating systems remain unaffected by this document. The dynamic behaviour of the local thermostats, sensors, or actuators is not covered in this document.A multi-distribution and/or multi-generation system needs a coordinated solution to prevent undesired interaction and is not part of this document.Table 1 shows the relative position of this document within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000 1.NOTE 1 In CEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.NOTE 2 The modules represent EPB standards, although one EPB standard can cover more than one module and one module can be covered by more than one EPB standard, for instance a simplified and a detailed method, respectively.[Table 1]

This document specifies the application of the FMC/TFM technology for the ultrasonic testing offusionwelded joints in metallic materials of minimum thickness 3.2 mm. It's is applicable only tocomponents with welds fabricated using metals which lead to isotropic (constant properties in alldirections) and homogeneous conditions. These classes of materials include welds in low carbonalloy steels and common aerospace grade aluminum and titanium alloys, provided they arehomogeneous and isotropic.

This document provides quality levels of imperfections in fusion-welded joints (except for beam welding) in all types of steel, nickel, titanium and their alloys. It applies to material thickness = 0,5 mm. It covers fully penetrated butt welds and all fillet welds. Its principles can also be applied to partial-penetration butt welds. Quality levels for beam-welded joints in steel are presented in ISO 13919-1. Three quality levels are given in order to permit application to a wide range of welded fabrication. They are designated by symbols B, C and D. Quality level B corresponds to the highest requirement on the finished weld. Several types of loads are considered, e.g. static load, thermal load, corrosion load, pressure load. Additional guidance on fatigue loads is given in Annex C. The quality levels refer to production and good workmanship. This document is applicable to Metallurgical aspects, e.g. grain size, hardness, are not covered by this document.
