ISO 8871-1-2003非腸道和制藥設備用彈性件.第1部分:含水autoclavates中的萃取物

1 This part of ISO 8871 defines procedures for classifying elastomeric parts for primary packs and medical devices used in direct contact with preparations for parenteral use, including both aqueous preparations and dry preparations which have to be dissolved before use.nIt specifies a series of comparative test methods for chemical evaluation by the determination of extractables in aqueous autoclavates (see Clause 4) and describes the various fields of application for elastomeric parts. Dimensions and functional characteristics are specified in the relevant International Standards. Required properties as specified in this part of ISO 8871 are regarded as minimum requirements.n2 This part of ISO 8871 is applicable for the categories of elastomeric parts given in Clause 3; specific requirements, however, are laid down in the relevant International Standards dealing with the items or devices listed in Clause 3.nElastomeric parts for empty syringes for single use are excluded from the scope of this part of ISO 8871 as they are not in contact with the injected preparation for a significant length of time.n3 Compatibility studies with the intended preparation have to be performed before the approval for final use can be given; however, this part of ISO 8871 does not specify procedures for carrying out compatibility studies.

ITU-T M.3050 SUPP 3 SPANISH-2004增強型電信運營圖譜(Etom)3號補充案.Etom到M.3400的映射.系列M:電信管理網和網絡維護.傳輸系統.電話電路.電報傳真和租用電路.電信管理網

ITU-T Recs M.3050.x series contain a reference framework for categorizing the business activities that service provider will use. The Enhanced Telecom Operations Map (or eTOM for short), which has been developed by the TeleManagement Forum, describes the enterprise processes required by a service provider and analyses them to different levels of detail according to their significance and priority for the business. This business process approach has built on the concepts of Management Services and Functions in order to develop a framework for categorizing all the business activities.

GSO IEC 62320-2-2010海上導航和無線電通信設備及系統.自動識別系統(AIS).第2部分:AIS AtoN站.操作和性能要求,試驗方法和要求的試驗結果

IEC 62320-2:2008(E) specifies the operational and performance requirements, methods of testing and required test results for AIS AtoN Stations compatible with the performance standards adopted by IMO Res. MSC.74(69), annex 3, Universal AIS. Incorporates the technical characteristics of non-shipborne AIS AtoN equipment, included in the relevant ITU-R and IALA Recommendations. Also takes into account the ITU Radio Regulations, where applicable.
