The work of preparing International Standards is normall
8、y carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the
9、work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare In
10、ternational Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of
11、 the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

12、vedIntroduction The purpose of this International Standard is to define the main terms and commercial specifications for pedestrian-controlled vibratory (percussion) rammers, used for material (primarily soil) compaction. These machines are typically used in the building trades to improve soil densi
13、ty characteristics.

14、out commercial specifications for pedestrian-controlled vibratory (percussion) rammers used in building construction. It is not applicable to rammers that compact by use of a tamping action of the foot-plate (shoe), nor is it applicable to explosion-type rammers. 2 Terms and definitions For the purp
15、oses of this document, the following terms and definitions apply. 2.1 pedestrian-controlled vibratory rammer pedestrian-controlled percussion rammer machine designed for the purpose of improving material (primarily soil) density and stiffness through use of a displacement-driven foot-plate for compa
16、ction See Figure 1. NOTE The machine compacts material through a vibrating action performed by the foot-plate. 2.2 prime mover driving energy source for the percussion mechanism See Figure 1. NOTE The following prime mover types are used for vibratory rammers: combustion engine (see Figure 2); hydra
17、ulic (see Figure 3). 2.3 vibratory mechanism system of components that translates the prime mover energy to the foot-plate 2.4 foot-plate shoe machine element that contacts the material being compacted See Figure 1. NOTE Foot-plate materials include steel, wood and polymer blends. ISO 19452:2008(E)
