本标准规定了我国职业的分类结构、类别、代码及说明。本标准适用于按职业分类的各种普查、调查统计及行政管理和国内外信息交流等。
本标准适用于对地理上广布的生产过程进行监视和控制,并以串行编码方式进行数据传输的远动设备及系统。 本标准也适用于远方保护设备及系统、支持配电自动化系统(DAS)的配电线载波(DLC)通信系统和有关的通信设备,例如电力线载波设备。 本标准规定了系统各组成部分的工作环境条件(气候、机械和其他非电影响因素)的等级。 本标准未考虑直接涉及火灾、爆炸和离子辐射的特殊环境条件。 任何未列入本标准的、但与设备的正常工作和寿命有关的其他环境条件(包括那些涉及移动式设备的环境条件)的详细要求,可由供需双方协商确定。
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')
