2、Industrial Standard revised by the Minister of Economy, Trade and Industry through deliberations at the Japanese Industrial Standards Committee, as the result of proposal for revision of Japanese Industrial Standard submitted by The Japan Iron and Steel Federation (JISF) with the draft being at- tac
3、hed, based on the provision of Article 12 Clause 1 of the Industrial Standardization Law applicable to the case of revision by the provision of Article 14. Consequently JIS G 3101 : 1995 is replaced with this Stan- dard. Attention is drawn to the possibility that some parts of this Standard may conf
4、lict with a patent right, application for a patent after opening to the public, utility model right or application for registration of utility model after opening to the public which have technical properties. The relevant Minister and the Japanese Industrial Standards Committee are not responsible
5、for identifying the patent right, application for a patent after opening to the public, utility model right or application for registration of utility model after opening to the public which have the said technical properties.

33、st piece shall be at a quarter- width position from a side edge, and further in the case of No. 4 test piece, it shall be at a quarter-thickness position from a surface as well as a quarter- width position from a side edge. When it is infeasible to allow the centre of the test piece to be at a quart
34、er-width position from a side edge or at a quarter- thickness position from a surface, however, the sampling should be performed as close to the aforementioned position as possible. Steel section The sampling position shall be as shown in annex 1 figure 1. When it is infeasible to take a specimen as
35、 shown in annex 1 figure 1, the sam- pling position should be as close to the aforementioned position as possible. In the case of the steel section from which a specimen is unable to take in the same manner as shown in annex 1 figure 1, the sampling position for the I section should be applied mutat
36、is mutandis. For other steel sections, it should be agreed between the purchaser and the supplier. b) PROTECTED BY COPYRIGHT 11.
