    Beskrivelse
    This Standard specifies the data structures and protocols for a telecommand space data link and the procedure for physical layer operation. Usually, the source of data on a telecommand space data link is located on the ground and the receiver is located in space. However, the Standard may also be used for space-to-space telecommand data links. Further provisions and guidance on the application of this standard can be found, respectively, in the following documents: • The higher level standard ECSS-E-ST-50 “Communications”, which defines the principle characteristics of communication protocols and related services for all communication layers relevant for space communication (physical- to application-layer), and their basic relationship to each other. • The handbook ECSS-E-HB-50 “Communications guidelines”, which provides information about specific implementation characteristics of these protocols in order to support the choice of a certain communications profile for the specific requirements of a space mission. Users of this present standard are invited to consult these documents before taking decisions on the implementation of the present one. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.

    Oprindelse:
    CEN
    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This standard, will represent a partial revision of the existing EN 16623:2015 "Paints and varnishes – Reactive coatings for the fire protection of metallic substrates – Definitions, requirements, characteristics and marking". It will specify definitions, properties and methods of testing for the characterization of reactive fire protection products that may be water or solvent based solutions, or made available as preformed profiles (e.g. as slabs or tubes). The specified requirements will generally be independent of the product type and form, except where the nature of the product needs something specific. The requirements of the standard will also be independent of the substrate material and the structural member to which it may be applied to provide the necessary fire performance. The requirements relevant to ensuring compatibility and correct application to different substrate materials will be dealt with in supplementary parts of this standard (viz Parts 2, 3, 4 and 5).

    Komite
    Beskrivelse
    ISO 16739:2013 specifies a conceptual data schema and an exchange file format for Building Information Model (BIM) data. The conceptual schema is defined in EXPRESS data specification language. The standard exchange file format for exchanging and sharing data according to the conceptual schema is using the Clear text encoding of the exchange structure. Alternative exchange file formats can be used if they conform to the conceptual schema. ISO 16739:2013 represents an open international standard for BIM data that is exchanged and shared among software applications used by the various participants in a building construction or facility management project. ISO 16739:2013 consists of the data schema, represented as an EXPRESS schema specification, and reference data, represented as definitions of property and quantity names and descriptions. A subset of the data schema and referenced data is referred to as a model view definition. A particular model view definition is defined to support one or many recognized workflows in the building construction and facility management industry sector. Each workflow identifies data exchange requirements for software applications. Conforming software applications need to identity the model view definition they conform to.

    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This standard defines the laboratory tests and requirements for approval of an aluminothermic welding process using welds produced in workshop conditions. It applies to the joining of new, grooved rails as described in EN 14811 of the same profile and steel grade. Welding of construction profiles and machined profiles are not covered in this standard. Compliance with the requirements of this standard does not of itself ensure the suitability of a welding process for specific conditions of track and traffic. The standard does not cover welds made between different rail sections, worn rails or different rail grades. In addition to the definitive requirements this standard also requires the items detailed in Clause 4 to be documented. For compliance with this standard, it is important that both the definitive requirements and the documented items be satisfied.
