This standard is not equivalent to 1902725-2, 1996 frequency bolt specification for assembly. 1 tool square transmission or sleeve simple Part 2: Dimensions of impact type nipple sleeve 3, all contents given in 15027 standard are effective for this standard, and the plate cultivation market in my country needs to supplement the 1502725 standard. The 23 specifications of the sleeve scale and 1 square hole size are between 10m and 1m. In order to use the square width, the 1502725 standard is directly given as the appendix of this standard. This standard is sufficient for the adjustment of the square transmission sleeve of the /-0 motor-operated screen plate. Compared with B3228-1088, this standard has the following major technical differences: 1. The name of the standard has been adjusted. 2. Foreword, ISO foreword and other contents have been added. 3. Technical requirements, test methods and acceptance planning and other contents, transportation and maintenance have been cancelled. 4. The specifications of the set have been supplemented and the relevant scales have been adjusted. 4. The implementation of the standard is GB/13228-1982. Appendix A of this standard is the requirements for the standard. Appendix B of this standard is the requirements for the hazard warning. The standard was proposed by the National Standardization Technical Inspection Committee of Pneumatic Tools: This standard is jointly approved by two units: Dayong Rock Drilling Pneumatic Tool Testing Institute, Sanhai Electric Tool Research Institute. The sponsors of this standard are Wei Wanjiang, Lan Xin, Zhang Yucheng and Liu Yaguang. The first standard was published in 197, the first draft was in 1982, the second draft was in 1958, and this is the third draft! G/3228-200
ISO Foreword
ISCI (International Organization for Standardization) is a world federation composed of national standardization bodies (ISO members). The development of inter-regional standards is generally carried out by ISO technical committees. Each volunteer who has a technical need for standardization has the right to express his opinion in the committee. International organizations, governmental agencies and non-governmental agencies that maintain relations with ISO may also participate in the relevant work of the committee. In all aspects of electrotechnical standardization, ISO maintains a cooperative relationship with the International Electrotechnical Commission (IEC). The international standards compiled by the Technical Committee are submitted to the member countries for voting and, after 75% of the votes are expressed, they are used as international standards. The same international standard 150) 2725-7 is developed by the Technical Committee S (> T29 February 1G, each with 1.0 parts). It is formulated by the Technical Committee. Except for 3SC27251, the second version of ISD27252 will be revised after review. 1S02725: 987 Edition, 1SD2726 consists of the following two parts, the general title is: Butterfly bolt nut assembly 1.
