本標準規定了自行履帶式和輪胎式液壓挖掘機及其工作裝置和附屬裝置的術語和商業文件的技術內容。本標準適用于通用的挖掘機及部件,不適用于步履式挖掘機專用的部件術語或商業規格。
本標準規定了液壓挖掘機和挖掘裝載機的挖掘力測定方法。本標準適用于GB/T 8498中定義的液壓挖掘機和挖掘裝載機。
GB/T 19930的本部分建立了在靜載荷作用下統一的、可重復的評價滾翻保護結構(ROPS)載荷承受性能的方法,并規定了對典型試件在這樣載荷作用下的性能要求。本部分適用于ISO 6165規定的大于6 t并小于50 t的液壓挖掘機的ROPS。當機器圍繞其回轉機架的縱軸滾翻360°,且與小于坡度30°硬黏土路面沒有失去接觸時,ROPS將為系座椅安全帶的司機確保小的擠壓保護空間。ROPS被應用在有滾翻危險存在的地方。本部分適用于基本型挖掘機或用于物件吊運、拆除或帶磁盤、蛤殼式鏟斗、抓斗或多爪夾具等附屬裝置的派生挖掘機的ROPS。本部分不適用于帶司機室起升裝置的挖掘機。
本標準規定了自行的履帶式和輪胎式機械挖掘機及其工作裝置/附屬裝置的術語。機械挖掘機主要用于牽引、挖掘、抓取及臨時吊裝作業。機械挖掘機的主機在鉆孔、打樁等特殊應用中,常被用作工作裝置/附屬裝置的載體,這些工作裝置/附屬裝置的尺寸規格不在本標準范圍之內。
GB/T 25687的本部分給出了中文、英文、法文和俄文的土方機械綜合術語的同義語列表,這些術語已經由現有的標準所定義。制定本部分的目的是:——促進世界范圍內土方機械信息的交流,特別是確保使用者之間的交流正確和一致;——明確人士(銷售、售后服務、技術、零部件分銷等)之間信息的交流;——簡化通關操作及統計調查;——對于不同的市場,盡可能翻譯成適用的主要語言。這些術語是以英文術語的字母順序進行排列和編號的,并且每項術語都由引用的標準所定義。
本標準規定了條斑紫菜(Pyropia yezoensis)絲狀體生產性培育的術語和定義、培育設施、果孢子采苗、培育、病害與防治和殼孢子采苗的技術要求。本標準適用于條斑紫菜絲狀體生產培育,果孢子采苗、殼孢子采苗的質量評定。
本標準規定了水產品加工領域常用的基本術語。本標準適用于水產品加工業的生產、流通、科研、教學及管理等相關領域。
本標準給出了青蛤(Cyclina sinensis)的學名與分類、主要形態特征、生長與繁殖、細胞遺傳學特性及檢測方法。 本標準適用于青蛤的種質檢測與鑒定。
This Recommendation deals with the application of splices of single-mode and multimode opticalfibres. It describes a suitable procedure for splicing that shall be carefully followed in order toobtain reliable splices between optical fibres or ribbons. This procedure applies both to single fibresor ribbons (mass splicing). In addition, this Recommendation advises on the optical, mechanicaland environmental testing methods, required for the splice system design and equipmentqualification . Further information is provided in the CCITT Manual \"Construction, installation,jointing and protection of optical fibre cables\".The fibres shall be in accordance with ITU-T Recommendations [1] to [7].
This document applies to flat bricks used for structural and non-structural masonry. Flat bricks with particular dimensional accuracy with special regard to the brick height. Their density does not exceed 1,6 kg/dm3.
This European Standard deals with the technical requirements to minimise the hazards listed in clause 4 and annex A. These hazards can arise during the operation and maintenance of equipment to store bulk materials in silos, bunkers, bins and hoppers and their built-in inlet and outlet devices when carried out in accordance with the specifications given by the manufacturer or his authorised representative. This standard deals with safety related technical verification during commissioning. Safety requirements and/or measures in this standard apply to equipment used in all environments. However, additional risk assessment and safety measures need to be considered in severe conditions, e. g. low or high temperatures out of the range covered by EN 60204-1, corrosive environments, strong magnetic fields, radioactive conditions and bulk materials to be stored included their flow the nature of which could lead to a dangerous situation. This European Standard deals with the technical requirements for electromagnetic compatibility (EMC).
This European Standard specifies the execution of diaphragm walls and the practical aspects which must be taken into account in the production of the working drawings. Diaphragm walls can be permanent or temporary structures. The following types are concerned: 1) retaining walls: usually made to support the sides of an excavation in the ground. They include: cast in situ concrete diaphragm walls; precast concrete diaphragm walls; reinforced slurry walls. 2) cut-off diaphragm walls: usually made to prevent migration of groundwater, clear or polluted, or of other liquids present in the ground. They include: slurry walls (possibly with membranes or sheetpiles); plastic concrete walls.
This European Standard specifies a test method for the quantitative determination of ignition and combustion delays of middle distillate fuels intended for use in compression ignition engines. The method utilizes a constant volume combustion chamber with direct fuel injection into heated, compressed synthetic air. This European Standard is applicable to middle distillate fuels, fatty acid methyl esters (FAME) and blends of diesel fuels and FAME. The method is also applicable to middle distillate fuels of non-petroleum origin, oil-sands based fuels, blends of fuel containing biodiesel material, diesel fuel oils containing cetane number improver additives and low-sulfur diesel fuel oils.
This part of DIN EN 60191 gives a glossary of semiconductor sockets for BGA, LGA, FBGA and FLGA. This standard intends to establish definition and unification of terminology relating to tests and burn-in sockets for BGA, LGA, FBGA and FLGA.
This part of BS 6349 gives recommendations for the design ofroll-on/roll-off (Ro-Ro) ramps, linkspans and walkways, used for thetransfer of passengers and vehicles between shore and ship.It applies to the structural elements only and does not cover the designof any operational equipment, traffic control, mechanical or electricalequipment, heating, lighting, life saving or rescue equipment other thanas the structures forming a facility need to incorporate and/or supportany of these features. Most geometrical aspects of fixed shore ramps arecovered in this part of BS 6349, but recommendations for all otheraspects are given in BS 6349-2.This part of BS 6349 does not apply to Ro-Ro facilities used by railvehicles in that it does not give recommendations for railway loadingand associated ramp gradients. However, many of its recommendationsare applicable to rail Ro-Ro facilities and can be used in the absence ofother guidance.NOTE This part of BS 6349 is generally intended to cover facilitiesconstructed in the British Isles. Although the majority of the contents aredirectly applicable elsewhere, local conditions might necessitatemodifications, e.g. environmental effects and traffic loading.
This part of BS 7121 gives recommendations for the safe use of lorryloaders. Subjects covered include management, selection of equipment,selection and training of personnel, procedures and precautions,testing, inspection, maintenance and examination.This part of BS 7121 is intended to be used in conjunction withBS 7121-2, which provides general guidance on the inspection, testingand examination of all types of cranes.
