8、 national standards bodies (ISO member bodies). The work of preparing International Standards is normally 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. Int
9、ernational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with t
10、he rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval
11、by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of 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. ISO 11093-9 was prepared by Technical Committee

18、s apply. 3.1 flat crush resistance quantity calculated from the load acting at right angles to the axis of the test piece at the first maximum or levelling off of the crushing force of the load deformation curve NOTE The flat crush resistance is expressed in kilonewtons per metre. 4 Principle The te
19、st piece is placed between two pressure plates arranged in parallel, so that its axis is parallel with the plane of the pressure plates and compressed at a constant plate rate until the first maximum, or levelling, of the load has been exceeded.

The compression testing machine shall be equipped with flat upper and lower platens held rigidl
21、y parallel during testing, permitting movement in a vertical direction only. The speed of the moving platen is the actual rate of travel of the platen while under the load. The force measurement shall have an accuracy of 1 % of the smallest crushing load measured. The switch-off limit for the crushi
22、ng force F for a testing machine with an automatic break detection is defined by 30 N, or 3 % from the true value. The testing machine shall be able to carry out the test so that the plates remain parallel in a range of 2 . 5.2 Cutting device for making test pieces, capable of producing a cut at 90
