The work of preparing International Standards is normally
9、carried out through IS0 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 wo
10、rk. IS0 collaborates closely with the International Electrotechnical Commission (I EC) 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 Int
11、ernational 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

21、 finer grades using a grain size of approximately 26 pm (600 FEPA) for the final finishing stage. 8.9.2.3 Containers of water, for storing the specimen strips at (23 f 2) “C and (37 f 1) “C for pre-test conditioning. 8.9.2.4 Pendulum impact testing machine, conforming to IS0 179:1993. A test capacit
22、y of 0,5 J is suitable. 8.9.3 Procedure Within (24 f 2) h of the beginning of the curing cycle of the denture base polymer, cut each plate lengthways into seven to eight equal strips, (50 f 2) mm long (l), (6 f 0,2) mm wide (w) and (4 f 0,2) mm in height (A). Machine the strips in a milling machine
23、(8.5.3.2.2) on the edges and equally from both moulded surfaces so that the dimensions remain slightly oversized. Take care to avoid overheating the specimen strips. Wet-grind all faces and edges smooth and flat with metallographic grinding papers (8.9.2.2). Cut a notch (type A) (see Figure 4) in th
24、e middle of each specimen strip as described in IS0 179:1993. Cut the notch edgewise to a depth of (1,2 f 0,l) mm leaving a residual depth beneath the notch of (4,8 f 0,l) mm.

Store 12 selected specimen strips in the container of water at (37+ 1) “C for 7 d + 2 h. Condition the specimen strips in the c
28、ontainer of water at (23 + 2) “C for (60 + 15) min prior to testing. After conditioning, remove a specimen strip from the water and place it on the specimen supports of the testing apparatus (8.9.2.4). Set the specimen supports at a separation of (40,O + 0,2) mm. Place the specimen strip with the no
29、tch facing away from the point of impact of the pendulum. Ensure that the specimen strip is centred with regard to the position of the notch and the point of impact of the pendulum. As soon as possible after removing each separate specimen strip from the water bath, release the pendulum in order to
30、fracture the specimen. Record the value of energy absorbed, JI. Re-zero the instrument and allow the pendulum to swing again with no specimen strip in place.
