Metalliteollisuuden Standardisointiyhdistys

 

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.

 

1.1 This International Standard specifies the requirements for seal-less rotodynamic pumps that are driven withpermanent magnet coupling (magnet drive pumps) or with canned motor, and which are mainly used in chemicalprocesses, water treatment and petrochemical industries. Their use can be dictated by space, noise, environmentor safety regulations.Seal-less pumps are pumps where an inner rotor is completely contained in a pressure vessel holding the pumpedfluid. The pressure vessel or primary containment device is sealed by static seals such as gaskets or O-rings.1.2 Pumps will normally conform to recognized standard specifications (e.g. ISO 5199, explosion protection,electromagnetic compatibility), except where special requirements are specified herein.1.3 This International Standard includes design features concerned with installation, maintenance andoperational safety of the pumps, and defines those items to be agreed upon between the purchaser andmanufacturer/supplier.1.4 Where conformity to this International Standard has been requested and calls for a specific design feature,alternative designs may be offered providing that they satisfy the intent of this International Standard and they aredescribed in detail. Pumps which do not conform with all requirements of this International Standard may also beoffered providing that the deviations are fully identified and described.Whenever documents include contradictory requirements, they should be applied in the following sequence ofpriority:a) purchase order (or inquiry, if no order placed), see annexes D and E;b) data sheet (see annex A) or technical sheet or specification;c) this International Standard;d) other standards.
