[en] The signing of electronic contracts and the certification of important documents are realized by utilizing blockchain, identity-based cryptography and electronic signature technology. Blockchain technology can realize the data distributed ledgers through the entire system nodes, the whole processes, and the entire transactions. Identity-based cryptography and electronic signature technology can achieve data integrity, privacy, and nonrepudiation. All data is shared by all participating nodes, the information in the cyberspace is more transparent, and the behavior is more traceable. A complete and compliant contract signing process and data certification is achieved. (paper)
[en] Information is given on the certification and type approval of wind turbines in Europe and on the following certification bodies: CIWI-Holland (Arnhem), Det Norske Veritas (Copenhagen Denmark), The Test Station at Risoe National Laboratory (Roskilde, Denmark), and Germanischer Lloyd (Hamburg, Germany).

[en] The Swiss-based International Organization for Standardization has provided a series of generic standards, known as ISO 9000 series, to assist companies in achieving quality management and production. In today's competitive global market, attaining ISO designation is becoming increasingly important for successful performance, and is considered to be almost a prerequisite to selling. . With this as the incentive, Petro-Canada decided to apply for ISO designation for its lubrication manufacturing operation. This contribution described the various steps involved in the company's effort to obtain certification.Briefly, the process begun in February 1993, with assembling an implementation team, consisting of representatives from every department of the lubricants division. Detailed manuals for all phases of operation were put together and sent to the licensing agency. Petro-Canada also committed itself to designing the products for what its customer's need, and not just products that are the most technologically advanced. After implementing these and other suggestions made by the certifying agency, Petro-Canada received its ISO 9001 in November 1993. The certification applies only to the lubrication plant and laboratory, but plans were said to be underway to implement ISO 9000 standards on a company-wide basis
[en] We present the CMS Pixel Data Quality Monitoring (DQM) system. The concept and architecture are discussed. The monitored quantities are introduced, and the methods on how to ensure that the detector takes high-quality data with large efficiency are explained. Finally we describe the automated data certification scheme, which is used to certify and classify the data from the Pixel detector for physics analyses.
[en] Most arms-control-treaty-monitoring scenarios involve a host party that makes a declaration regarding its nuclear material or items and a monitoring party that verifies that declaration. A verification system developed for such a use needs to be trusted by both parties. The first concern, primarily from the host party's point of view, is that any sensitive information that is collected must be protected without interfering in the efficient operation of the facility being monitored. This concern is addressed in what can be termed a 'certification' process. The second concern, of particular interest to the monitoring party, is that it must be possible to confirm the veracity of both the measurement system and the data produced by this measurement system. The monitoring party addresses these issues during an 'authentication' process. Addressing either one of these concerns independently is relatively straightforward. However, it is more difficult to simultaneously satisfy host party certification concerns and monitoring party authentication concerns. Typically, both parties will want the final access to the measurement system. We will describe an alternative approach that allows both parties to gain confidence simultaneously. This approach starts with (1) joint development of the measurement system followed by (2) host certification of several copies of the system and (3) random selection by the inspecting party of one copy to be use during the monitoring visit and one (or more) copy(s) to be returned to the inspecting party's facilities for (4) further hardware authentication; any remaining copies are stored under joint seal for use as spares. Following this process, the parties will jointly (5) perform functional testing on the selected measurement system and then (6) use this system during the monitoring visit. Steps (1) and (2) assure the host party as to the certification of whichever system is eventually used in the monitoring visit. Steps (1), (3), (4), and (5) increase the monitoring party's confidence in the authentication of the measurement system.
[en] In cooperation with Ecofys (consultancy and research bureau), Holland Solar (Dutch Association for the Application of PV-systems), and ODE (Organization for Renewable Energy), the Netherlands Energy Research Foundation (ECN) is working on a certification system for PV-systems and its components. The certification system is important for both the consumers and the producers of PV-systems, and will follow existing international modes of operation. A state of the art is given. 1 ill
[en] The Rules were issued based on the Decree of the State Office for Nuclear Safety Chairman as of 12 January 1993. The responsibilities of the State Examination Commission board and members are laid down, requirements laid down on the candidates for examination are specified, and the examination structure and procedure, evaluation, and possibility of resitting are defined. The examination is divided into a written, oral, and practical part. (J.B.)
