ISO 272-1982紧固件 六角产品 对边宽度

Specifies the widths to be used in the respective product standards; it sets out a logical ratio between underhead (or nut) bearing area and the tensile stress area of the screw thread.

ISO 691-2005螺钉和螺母用装配工具.扳手和套筒扳手的开口.常用公差

This International Standard specifies tolerances on wrench and socket openings for screws and nuts (or similar parts) having metric width across flats dimensions, as shown diagrammatically below.It gives, for each dimension, the tolerances for general use, defined by its two deviations, minimum and maximum, with respect to the nominal value.These deviations have been determined in relation to the width across flats tolerances for screws and nuts specified in ISO 4759-1 and with regard to the manufacture of tightening tools.

ISO 722-1991凿岩钎具 六角形与圆形中空钎钢 棒材

Specifies the dimensions for seven nominal sizes. This third edition cancels and replaces the second edition (1985), which has been technically revised (addition of round drill steels and extension of the range of sizes).

ISO 723-1991凿岩钎具 六角中空钎杆的锻造钎尾和钎肩

Specifies the dimensions of both forged collared shanks and corresponding chuck bushings. Values are given for five nominal sizes. This second edition cancels and replaces the first edition (1974), which has been technically revised (extension of the range of sizes and specification of the size of the internal diameter at the forged collar).

ISO 887-2000米制普通螺栓、螺钉和螺母用平垫圈 总方案

This International Standard specifies the full range of the nominal dimensions of product-grade-A and -C plain washers for general-purpose bolts, screws and nuts of nominal thread diameters ranging from 1 mm to 150 mm inclusive.This International Standard is not applicable to washers for screw and washer assemblies in relation to hole diameters and thicknesses.Information on the use of plain washers is given in annex A.

ISO 887 CORR 1-2006通用米制螺栓、螺钉和螺母用普通垫圈.一般示意图.技术勘误1

This standard is about Plain washers for metric bolts, screws and nuts for general purposes - General plan; Technical Corrigendum 1

ISO 1085-2016螺钉和螺母的装配工具. 双头扳手. 对边尺寸组配

This document specifies the size pairing of double-ended wrenches with unequal nominal widths across flats. NOTE The wrenches covered by this document are those identified in ISO 1703:2005 under reference nos. 1 1 01 02 0, 1 1 02 03 0, 1 1 02 04 0, 1 1 02 05 0, 1 1 02 06 0, 1 1 02 08 0.

ISO 1173-2001螺钉和螺母用装配工具 手动和机动旋转头的传动端及连接部件 尺寸，转矩试验

This International Standard specifies the dimensions and torque testing of drive ends for hand- and machine-operated screwdriver bits as well as to driving spindles of screw driving machines.It ensures the interchangeability of tool bits and tool holders.This International Standard defines only the distinctive features of individual drive ends. Details of design, e.g. of fixing devices, are left to the user of this International Standard.

ISO 1174-2-1996螺钉和螺母用装配工具 传动方头 第2部分:机动套筒扳手工具的传动方头

Specifies the dimensions and designation of driving squares for power socket tools.

ISO 1711-2-2019螺钉和螺母的装配工具. 技术规格. 第2部分: 机动套筒(冲击)

This document specifies hardness and minimum torsional strength for machine-operated square drive sockets in accordance with ISO 2725-2 intended for use with impact wrenches. EXAMPLE Reference nos. 2 2 02 01 0; 2 2 02 02 0; 5 2 00 04 0. NOTE The sockets mentioned above are listed under their respective reference numbers in ISO 1703.

ISO 1813-2014皮带传动.包括宽截面带及六角带的多楔带、有接头三角皮带、三角皮带.抗静电带的导电性:特性和试验方法

This International Standard specifies the maximum electrical resistance of antistatic endless V-ribbed belts,joined V-belts, and single V-belts including wide section belts and hexagonal belts,as well as corresponding production control and individual proof methods of measurements.The application of this International Standard is limited to new belts intended to be used in an explosive atmosphere or in situations where there is a fire risk. The test is intended to ensure that the belt is sufficiently conductive to dissipate charges of electricity which can form on it in service.

ISO 1927-2-2012整体(粗制)耐火材料产品.第2部分:试验取样

This part of ISO 1927 gives guidance on the sampling of\nmonolithic (unshaped) refractory materials for the purpose of\ninspection and testing for quality and general information on the\nreduction and treatment of samples prior to testing. It covers all\nmaterials formulated as monolithic refractory materials.\nNOTE The term \"monolithic\" is the preferred term, whereas\n\"unshaped\" is commonly used in Europe. For the purposes of this\npart of ISO 1927, the terms \"monolithic\" and \"unshaped\" can be used\ninterchangeably.

ISO 1927-6-2012整体(粗制)耐火材料产品.第6部分:物理性质的测量

This part of ISO 1927 specifies methods for the determination of\nproperties of unshaped materials from test pieces prepared and\nstored according to ISO 1927-5.\nThe methods are applicable to dense and insulating castables and\nto ramming materials (including plastics) as defined in ISO 1927-1\nbefore and after firing.
