This document specifies a method for exposing specimens made from poly(vinyl chloride) (PVC) based profiles to xenon-arc radiation, in order to assess changes in characteristics. It is applicable to PVC based profiles including those covered with foil, paint, thermo-laminated foils or coextruded. NOTE The determination of changes in colour and variations of properties after exposure of PVC based profiles to xenon-arc radiation is described in an informative Annex A.

 

This European Standard covers methods for the calculation of the design heat load for single rooms, building entities and buildings, where the design heat load is defined as the heat supply (power) needed to maintain the required internal design temperature under design external conditions. Table 1 shows the relative position of this standard 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 may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1. (...)

 

ISO 4029:2003 specifies the characteristics of hexagon socket set screws with cup point and threads from M1,6 up to and including M24 and of product grade A.

 

This European Standard specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of ground power equipment, when carried out in accordance with the specifications given by the manufacturer or his authorised representative. It also takes into account some performance requirements recognised as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines and service companies. This European Standard applies to: - ground power units either self-propelled or towable (Examples see Annex A); - ground power equipment when mounted on other GSE; - ground power accessories intended for ground power equipment (including accessories for fixed equipment). This European Standard does not apply to: - the electrical characteristics of the supply, the type of power supply system and related measures against contact; - any electrical supply system not intended for aircraft use; - the on-board electrical system of the aircraft. This European Standard does not establish requirements for noise and vibration. Noise and vibration are dealt with respectively in EN 1915 4 and EN 1915 3. This European Standard does not deal with hazards in respect to a standard automotive chassis and from other vehicles on the apron. This Part of EN 12312 is not applicable to ground power equipment which is manufactured before the date of publication of this European Standard by CEN. This part of EN 12312 is intended to be used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 (for vehicles) and EN 1915-4.

 

This document specifies the classification imperfections likely to be generated during an additive manufacturing process by DED for metallic parts. This document also indicates the most probable causes of the formation of imperfections and includes illustrations. Acceptance criteria for imperfections are not included in this document.

 

This document specifies requirements for the design and selection of electrical, mechanical, hydraulic and pneumatic equipment used in all types of cranes and their associated fixed load lifting attachments with the objectives of protecting personnel from hazards affecting their health and safety and of ensuring reliability of function. NOTE Specific requirements for particular types of cranes, and for load lifting attachments, are given in the appropriate European Standard. The electrical equipment covered by this document commences at the point of connection of the supply to the crane (the crane supply switch) including systems for power supply and control feeders situated outside the crane, e.g. flexible cables, conductor wires or bars, electric motors and cableless controls. The principles to be applied for cranes transporting hazardous loads are given in this document. Particular requirements are given for cranes transporting hot molten metal. This document does not cover the detail design of individual items of equipment except with regard to their selection for specific aspects of use. The proof of competence calculations and related strength requirements or safety margins of equipment and components are not covered by this document. NOTE Some safety margins are given here for issues not covered in the EN 13001 series. Hazards due to noise are not covered by this document. They are addressed in safety standards specific to each type of crane. The specific hazards due to potentially explosive atmospheres, ionising radiation, and operation in electromagnetic fields beyond the range of EN 61000-6-2 are not covered by this document. The significant hazards covered by this document are identified in Annex A. This document is not applicable to cranes manufactured before the date of its publication.

 

This document specifies a method which covers the determination of Gd2O3 content in UO2 fuel pellets, by X-ray fluorescence spectrometry. Either wave dispersion X-ray fluorescence (WD-XRF) or energy dispersion X-ray fluorescence (ED-XRF) is applicable, however, this document states a method by using WD-XRF using Gd La-line. This method has been tested for mass fractions of from 2 % to 10 % Gd2O3.

 

ISO 4026:2003 specifies the characteristics of hexagon socket set screws with flat point and threads from M1,6 up to and including M24 and of product grade A.

 

This document specifies the measuring of parameters needed to calculate arc energies for arc welding processes.
