(6.2) Using a hammer or punch, break the specimen by striking the point of impact as indicated in Fig. 1 . Furthermore,
31、use one sheet of specimen per one point of impact. (6.3) Observe the state of fragments immediately, and measure in accordance with (7). Furthermore, using photosensitive papers, measurement can be carried out by using the projected images thereof. (7) Measuring method of fragments (7.1) Peripheral
32、region Select the portions where the size of fragments is the coarsest and the fin- est, and count the number of fragments in a frame, using the counting frame of 50 mm x 50 mm on these portions. However, when the number of frag- ments in the counting frame of 50 mm x 50 mm is less than 40 pieces, c
33、ount the number of fragments in the counting frame of 100 mm x 100 mm in- cluding that portion. Further, the fragments on the side of the counting frame shall be counted as 0.5 piece. Measure the number of pieces of fragments exceeding 3 cm2 and respective areas. Count the number of slender fragment
34、s exceeding 75 mm in length, as well as measure respective length. Measure the angle formed between the slender fragment extending to the periphery of a specimen and the periphery of the specimen and the length of that specimen. Exclude the regions of 20 mm from the periphery of specimen and within
35、75 mm in radius from the point of impact from the subject of measurements.

41、carried out. 3.3.2 Toughened glass fragmentation test The fragmentation test of the tough- ened glass shall be carried out in accordance with the following. (1) Object This test shall be carried out to examine whether the conditions of the fragments have necessary safety or not, when the toughened g
42、lass have been broken. (2) Specimens Three sheets of products of flat surface or single curved surface and four sheets of the products of multiple curved surface shall be taken as the specimens. (3) Equipments and instruments to be used (3.1) The hammer or punch of (0.2+0.05) mm in radius of curvatu

Point 1: In the place of minimum radius of curvature at the end of specimen, and the point of 30 mm towards t
44、he centre from its medium point. Point 2: The place of 30 mm from the periphery on the shortest or the longest centre line of the specimen, and when the tong marks exist, the side where the tong marks exist shall be selected. Point 3: Approximately the central point of the specimen. Point 4: It is a
45、pplicable to the specimen of compound curved surfaces only, and is the point of minimum radius of curvature on the longest median line of the specimen. Further, the positions of point of impact are indicated in Fig. 2. Even though the point 1, point 2, and point 4 have been illustrated two places or
