3、ance with the Industrial Standardization Law. Concerning the pure titanium for industry, in 1964, Japanese Industrial Standards for each product such as plate or bar have been established, which have remarkably contributed for the improvement of electric power industry, chemical industry, or related
4、 other industries. In recent days, this material has been widely used for not only industries but also familiarly-used material for peoples livelihood. With the background of above-mentioned condition, the standard about rods, bars and forgings of titanium alloys was established as JIS H 4657, and t
5、he standard about sheets and plates of titanium alloys was established as JIS H 4607 in 1991. Additionally, concerning titanium alloy tubes and pipes, TIS 9431 (standard of Japan Titanium Society) was established in 1994. In this time, since titanium alloy (Ti-3A1-2.5V) tube was requested to be stan
6、dardized as a Japanese Industrial Standard, on the basis of TIS 9431, JIS has been prepared and established.

35、f the tubes of which ingot, thermal treatment, manufacturing method, and sectional dimen- sions are the same, take arbitrary one tube from them, and prepare the sample according to JIS H 1610. When the sample, which is to be used for the chemi- cal analysis of the elements other than hydrogen, is pr
36、epared, test piece can be taken from the ingot or the material. b) To prepare the sample for tensile test and flattening test, take any two test tubes from every 100 tubes or its fraction of which ingot, thermal treatment, manufacturing method, and dimensions are the same, and then prepare one test
37、piece for tensile test from each tube. From both ends of one of two test tubes, one test piece for flattening test shall be taken respectively. STD-JIS H 4b37-ENGL 2000 m 4733b08 05b730b b74 m 6.
