GB/T 25444的本部分規(guī)定了移動式和固定式近海設施危險區(qū)域分級和危險區(qū)域內電氣設備的選擇要求,適用于近海石油工業(yè)的鉆井、生產、處理及貯存,包括管路、泵站或管內清掃站、空壓機站和外露的單浮筒系泊設施。本部分適用于危險區(qū)域內的交流電壓不大于35000V和直流電壓不大于750V,永久的、臨時的、移動或手持的所有電氣裝置。本部分不適用于艙室內的醫(yī)用電氣裝置或液貨船上的電氣裝置。
本標準規(guī)定了個人助理機器人的本質安全設計、保護措施和使用信息的要求和準則。本標準特別針對以下三類個人助理機器人:——移動仆從機器人;——身體輔助機器人;——載人機器人。這些機器人通常執(zhí)行任務,以提高預定用戶的生活質量,不論用戶的年齡或能力。本標準描述了使用這些機器人的危險,并且提出消除、降低其至可接受水平的要求。本標準涉及人機物理接觸應用。本標準包含了每類個人助理機器人的重大危險類型及危險處理方式。本標準同樣適用于個人助理應用中的機器人裝置并將其視為個人助理機器人。本標準僅限于地面機器人。本標準不適用于:——行走速度大于20 km/h的機器人;——機器人玩具;——水下機器人和飛行機器人;——工業(yè)機器人,請參考GB 11291;——用作醫(yī)療器械的機器人;——軍事或警力用途機器人。本標準使用范圍主要針對當個人助理機器人合理安裝和維護,并按預定目的使用以及其他可合理預見的條件下,出現(xiàn)的與個人助理相關危險,酌情包括家養(yǎng)動物或財產的危險(定義為“安全相關對象”)。本標準不適用于在標準發(fā)行前制造的機器人。本標準涉及附錄A中描述的所有重大危險、危險狀況或危險事件。請注意,本標準出版時,沖擊危險(如碰撞)沒有為認可的詳細數據(如疼痛或傷害極限)。
本規(guī)程適用于高密度聚乙烯外護管聚氨酯泡沫塑料預制直埋熱水管道泄漏監(jiān)測系統(tǒng)的設計、施工、調試、驗收、運行與維護。
These requirements cover small wind turbine systems (WT) and electrical subassemblies. With respect to this standard, small WT are considered to be wind turbines where a user or service person cannot or is not intended to enter the turbine to operate it or perform maintenance. These units are intended for use in stand-alone (not grid-connected) or utility interactive applications. Utility-interactive,grid-tied WT are operated in parallel with an electric power system (EPS) to supply power to common loads.
This European Standard specifies requirements, methods of test and performance criteria against which thecompatibility of components and their performance can be assessed when used in combination to form anelectrically controlled hold-open system. It also specifies requirements for the integrity of such hold-opensystems when connected to fire detection and fire alarm systems or other systems, including the signalexchange and technical data for interfaces.This European Standard provides requirements for the application of electrically controlled hold-open systemsused for fire/smoke doors in buildings, where such doors are required to be self-closing. It covers planning,design (see Annex A), installation (see Annex B), commissioning, use and maintenance (see Annex E) ofhold-open systems, intended for the protection of life and/or the protection of property. This may also includehold-open systems, or components of the hold-open system, that are self-contained in a single enclosure.Electrically controlled hold-open systems manufactured, installed and serviced in accordance with thisEuropean Standard are recommended for use wherever there is a requirement for reliable hold-open andrelease of an individual self-closing fire/smoke door assembly in the case of fire.The use of hold-open systems for closures in conveyor systems conforming to EN 1366-7, which applies inconjunction with EN 1363-1, may require additional proof of suitability, which is not covered by this EuropeanStandard.This European Standard does not cover design, installation, commissioning, use and maintenance of buildingfire detection and fire alarm systems (covered by CEN/TS 54-14) but does cover the connection of hold-opensystems conforming to this European Standard to building fire detection and fire alarm systems, under certainprescribed conditions.This European Standard does not cover the requirements of performance characteristics and operationalenvironment conditions of particular components of a hold-open system, where these requirements arealready covered by European specifications, and which include appropriate test methods to assurereproducible test results for the product conformity assessment. These European Standards are referred to inClause 5.This European Standard does not cover electrically controlled systems used for smoke venting purposes orsystems that allow the door to remain open under fault conditions (i.e. not fail-safe).This European Standard does not cover electrically controlled hold-open systems that are not connected tomain power supply and are battery powered only.
This part of IEC 62109 applies to the power conversion equipment (PCE) for use inPhotovoltaic (PV) systems where a uniform technical level with respect to safety is necessary.This standard defines the minimum requirements for the design and manufacture of PCE forprotection against electric shock, energy, fire, mechanical and other hazards.This standard provides general requirements applicable to all types of PV PCE. There areadditional parts of this standard that provide specific requirements for the different types ofpower converters, such as Part 2 - inverters. Additional parts may be published as newproducts and technologies are commercialised.
This standard specifies U.S. consensus standard methods, instrumentation, and facilities for measurement 9 of radio-frequency (RF) signals and noise emitted from electrical and electronic devices in the frequency 10 range 9 kHz to 40 GHz. It does not include generic nor product-specific emission limits. Where possible, the specifications herein are harmonized with other national and international standards used for similar purposes.
