The work

12、 of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmen

13、tal, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The ma

14、in task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. At

15、tention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

BS ISO 10276:2010ISO 10276:2010(E) ISO 2010 All rights reserved vIntroduction This International Standard has been produced to enable package owners, designers, users and regulatory organizations to have at their disposal a comprehensive document covering all aspects of trunnions. Experienc

17、e has been drawn from the extensive knowledge of owners, designers, users and competent authorities. Contained herein are the recommended minimum criteria covering various aspects of trunnions. It is intended that quality assurance, although referred to separately in Clause 8, be applied during the

18、application of part or all of this International Standard. No account is taken in this International Standard of any intermediate device that can be used between the packaging trunnions and the transport vehicle with respect to the relevant energy-absorbing effects. Intermediate devices (sometimes r

19、eferred to as transport frames, supports or cradles) are used to support and secure the package to the transport vehicle.

20、adioactive material 1 Scope This International Standard covers trunnions fitted to radioactive-material transport packages that are subject to the approval and licensing by competent authorities in accordance with the IAEA No. TS-R-1. Aspects included are design, manufacture, maintenance and quality

21、 assurance. Subject to agreement between the interested parties, it can also be applied to packages that are not subject to the approval by competent authorities. This International Standard covers trunnion systems used for tie-down during transport and trunnions used for tilting and/or lifting. Thi

22、s International Standard does not supersede any of the requirements in the IAEA No. TS-R-1, nor any of the requirements of international or national regulations, concerning trunnions used for lifting and tie-down. This International Standard is applicable to new package design. 2 Normative reference

Imperative statements also

44、 denote requirements. To conform with this International Standard, all operations shall be performed in accordance with its requirements, but not necessarily with its recommendations. The words “can” and “could” denote possibility rather than permission. The word “will” denotes that an event is cert

45、ain to occur rather than a requirement. 4.2 Relevant regulations The main applicable document is IAEA No. TS-R-1. Other relevant national or international regulations should also be considered to ensure that any differences with the IAEA regulations are taken into account. This International Standar

46、d does not relieve the relevant parties of the responsibility for compliance with any requirement of the government of any country through or into which the package is being transported, including regulations applicable within the nuclear power plants. 4.3 Quality assurance Quality assurance, althou
