本標準規定了我國職業的分類結構、類別、代碼及說明。本標準適用于按職業分類的各種普查、調查統計及行政管理和國內外信息交流等。
本標準適用于對地理上廣布的生產過程進行監視和控制,并以串行編碼方式進行數據傳輸的遠動設備及系統。 本標準也適用于遠方保護設備及系統、支持配電自動化系統(DAS)的配電線載波(DLC)通信系統和有關的通信設備,例如電力線載波設備。 本標準規定了系統各組成部分的工作環境條件(氣候、機械和其他非電影響因素)的等級。 本標準未考慮直接涉及火災、爆炸和離子輻射的特殊環境條件。 任何未列入本標準的、但與設備的正常工作和壽命有關的其他環境條件(包括那些涉及移動式設備的環境條件)的詳細要求,可由供需雙方協商確定。
EN 1991-1-1 gives design guidance and actions for the structural design of buildings and civil engineering works including some geotechnical aspects for the following subjects:- Densities of construction materials and stored materials;- Self-weight of construction works;- Imposed loads for buildings.Section 4 and Annex A give nominal values for densities of specific building materials, additional materials for bridges and stored materials. In addition for specific materials the angle of repose is provided.Section 5 provides methods for the assessment of characteristic values of self-weight of construction works.Sectuib 6 gives characteristic values of imposed loads for floors and roofs according to category of use in the following areas in buildings:- residential, social, commercial and administration areas;- garage and vehicle traffic areas;- areas for storage and industrial activities;- roofs;- helicopter landing areas.The loads on traffic areas given in Section 6 refer to vehicles up to a gross vehicle weight of 160 kN. The design for traffic areas for heavy vehicles of more than 160 kN gross weight needs to be agreed with the relevant authority. Further information may be obtained from EN 1991-2.For barriers or walls having the function of barriers, horizontal forces are given in Section 6. Annex B gives additional guidance for vehicle barriers in car parks.For the design situations and effects of actions in silos and tanks caused by water or other materials see EN 1991-3.
This part of the standard specifies: - the technical requirements that must be met by the Terminology Management System [TMS] that will be used to manage and store the 'Agreed RMI Terminology' - the requirements for the Registration Authority [RA] (i.e. the agency responsible for maintaining and publishing the 'Agreed RMI Terminology')
