This translation has been made based on the original Japanese Industrial Standard revised by the Minister of Economy, Trade and Industry through deliberations a t 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 attached, 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 3192 : 2000 is replaced with this Standard.

The mass of the steel sections shall, as a rule, be expressed by theoretical mass in kilogramme.
The method for calculation of mass of the steel sections shall be in accordance with table 5 based on the nominal dimensions.
The sectional area and unit mass of the steel sections obtained in terms of the standard sectional dimension in accordance with b) are as shown in attached tables 1 to 8.

2 The symbols which are used for the calculation of the sectional area stand for the sectional dimensions of the steel section, and the relation of the symbols t o the respective parts of the section is shown in attached tables 1 to 8.
3 The rounding off of the numerical values shall be in accordance with Rule A in JIS Z 8401.
8 Tolerance on mass When applying of the mass tolerances for steel sections are requested by the purchaser, they shall conform to table 6. In this case, the tol- erances on mass shall be expressed by the quotient in percentage tha t the differ- ence between the theoretical mass and actual mass is divided by the theoretical mass.

9 Appearance The appearance of the steel sections shall be as follows:
The steel sections shall be free from defects tha t are detrimental to practical use.
In the case where there are some harmful defects on the surface of the steel sections, the manufacturer may remove or repair the defects by grinding or welding. In this case, the operation shall be as follows:
1) Conditioning with grinder
1.1) The sectional dimensions of the steel sections after conditioning shall fall within the range of the tolerances. When approved by the purchaser, how- ever, this restriction may be applied flexibly according to its application.
1.2) The conditioned parts of the steel sections shall be finished neatly, and the boundary between the repaired portions and as rolled surface shall be smoothly finished.
2) Repair by welding
2.1) The harmful defects of the steel sections shall be repaired by welded overlay after complete removal by means of appropriate method such as chipping or grinding.
2.2) The depth of the defect-removed portion previous to repair by welding shall be not more than 30 % of the nominal thickness. For the toe of the flange of the steel sections, however, the depth shall fall within the nominal thick- ness of the flange from the edge (12 mm max.).
2.3) The repaired area by welding shall fall within 2 % of the whole surface area of the steel sections.

2.4) The weld repairing shall be carried out by suitable means according to the kind of steel products.
The welded part of the steel sections shall be free from undercut or over- laps around the fringe of welds. The reinforcement of weld shall be a t least 1.5 mm in height from the rolled surface, and this shall be removed by chipping, grinding, etc. and smoothly finished as high as the rolled surface.
The heat-treated steel sections themselves shall be heat-treated once again after the repair by welding.
