(i) Assuming the cylinder is always to be supported horizontally at its two finishes only and also to be uniformly loaded in excess of its whole size consisting of the burden for each unit of duration in the straight cylindrical portion full of drinking water and compressed to the required test force; the sum of two periods the maximum tensile stress in the bottom fibers as a consequence of bending, plus that in the same fibers (longitudinal stress), because of hydrostatic exam may not exceed 80 percent from the minimal generate energy in the steel at these kinds of optimum pressure. Wall thickness need to be improved when important to meet the prerequisite.

Open-hearth or electrical metal of uniform excellent has to be utilized. A heat of steel produced under table 1 In this particular paragraph (b), Test chemical Evaluation of which is marginally away from the required selection, is acceptable, if satisfactory in all other respects, furnished the tolerances proven in table two On this paragraph (b) usually are not exceeded except as authorised with the Affiliate Administrator. The following chemical analyses are approved:
