    Beskrivelse
    The deliverable defines minimum requirements on the measurement of the power frequency for DER to be connected to in electrical energy supply networks for the self-regulating control of generating plants as well as loads in the case of power frequency deviations. Characteristics to be developed are: a) Framework conditions for measurement and analysis Recommended combinations of admissible measurement duration and required accuracy are given for different kind of use cases at least the P-by-f droop (LFSM) and control strategies using the rate of change of frequency (ROCOF), see e.g. CLC TS 50549-1 and TS 50549-2. These comprise cases with high accuracy (and certain measurement duration) as well as cases with a focus on fast reaction (and lower accuracy): - Maximum permissible duration of a measurement & analysis interval; - Minimum accuracy of the measurement & analysis; - Ranges for the response characteristic (step response) of the measuring & analysis element. The scope also comprises requirements for the derivative of the measuring element’s output. The properties of the rate of change of frequency (df/dt) determine the performance of sophisticated protection systems and the emulation of system inertia. b) Immunity requirements Requirements for the immunity of the measurement & analysis procedures have to be developed against electromagnetic disturbances which typically prevail in distribution networks more often than at transmission level, for example (sub)harmonics, vector jumps, flicker and voltage displacements after switching operations, etc. The correct functioning of measurement & analysis shall also be ensured outside operational security limits according to future Network Code Operational Security. c) Testing requirements Test procedures shall be developed to verify the correct response of measurement & analysis in a reproducible manner. The required accuracy has to be proved and an immunity assessment in an electromagnetically noisy ...

    This new international standard will, in two parts, integrate EN 15265, EN 15255, EN-ISO 13791 and EN-ISO 13792. Depending on the development, the split between part 1 and part 3 will be between a detailed method(s) (part 1) and simple method(s) (part 3). This standard will contain a consistent and integrated set of requirements and additional descriptions of the thermal balance model for the hourly calculation of the energy needs for heating and cooling, the heating and cooling loads and indoor temperature in a thermal zone of a building. It will be directly usable by ISO 52016-1 for the calculation of the energy needs and by other EPB standards (e.g. from CEN/TC 156) dealing with needs, loads or indoor (e.g. summer) temperature calculations.

    Beskrivelse
    This guide will include post-process non-destructive testing of additive manufacturing (AM) of metallic parts with a comprehensive approach. It will cover several sectors and a similar framework can be applied to other materials (e.g. ceramics, polymers, etc.). In-process NDT and metrology standards will be referenced as they are being developed. This guide will present current standards capability to detect which of the Additive Manufacturing (AM) flaw types and which flaws require new standards, using a standard selection tool. NDT methods potential to detect AM flaws not covered by current standards will be recommended, and as new standards for flaws not covered by current standards are developed, they will be referenced in this standard via document updates. This part of the International Standard: • Categorises AM defects • A review of relevant current standards • Enables suitable current standard NDT method/s to be used; • Details method specific to additive manufacturing and complex 3D geometries; • Outlines existing non-destructive testing techniques applicable to some AM types of defects; This part of the International Standard is aimed at users and producers of additive manufacturing processes. It applies wherever additive processes are used, and to the following fields in particular: • Safety critical applications; • Assured confidence in additive manufacturing; • Reverse engineered products manufactured by additively manufactured; • Test bodies wishing to compare requested and actual geometries. NOTE – Most metal inspection methods in NDT use ultrasound or X-rays, but these techniques cannot always cope with the complicated shapes typically produced by AM. In most circumstances X-ray computed tomography (CT) is a more suitable method, but it also has limitations and room for improvement or adaptation to AM, on top of being a costly method both in time and money.
