(iii) When dimensions of cylinder will not allow securing straight specimens, the specimens may very well be taken in any location or path and will be straightened or flattened cold, by strain only, not by blows.
(iii) If due to welded attachments on the top head There's inadequate surface area from which to have a specimen, it might be taken from a representative head of the identical heat treatment because the take a look at cylinder.
Open up-hearth or electric steel of uniform high-quality should be made use of. A heat of steel built under table one With this paragraph (b), check chemical Evaluation of that is a bit from the specified selection, is suitable, if satisfactory in all other respects, supplied the tolerances shown in desk two On this paragraph (b) usually are not exceeded other than as accredited by the Associate Administrator. The subsequent chemical analyses are licensed:
When this aspect demands that a packaging be marked using a DOT specification or UN typical marking, marking of your packaging with the right DOT or UN markings may be the certification that—
(3) Substance have to be determined by a suitable strategy that could recognize the alloy, the aluminum producer's cast quantity, the solution warmth treat batch range along with the ton quantity.
(i) The remaining cylinders in each great deal need to be tested with the proof stress water-jacket or immediate expansion exam method as prescribed in CGA C-one. The minimum amount examination force should be managed for the particular timeframe along with the testing gear need to be calibrated as prescribed in CGA C-1.
(1) The attachment towards the tops or bottoms of cylinders of neckrings, footrings, handlers, bosses, pads, and valve defending rings is approved furnished that these attachments and also the part of the container to which They are really attached are created of weldable steel, the carbon content material of which can not exceed 0.25 %.
(B) With data specifying the kind(s) and dimensions with the closures, including gaskets and every other elements necessary to make certain that the packaging is able to productively passing the applicable effectiveness tests. This facts need to include any processes to generally be followed, like closure instructions for interior packagings and receptacles, to effectively assemble and shut the packaging for the goal of preventing leakage in transportation.
(3) Every specimen for the tension and Charpy affect assessments has to be taken through the facet here wall of the cylinder or from a ring which has been heat dealt with While using the completed cylinders of which the specimens need to be representative. The axis from the specimens have to be parallel for the axis with the cylinder.
All spun cylinders and plugged cylinders must be tested for leakage by fuel or air pressure immediately after the bottom has long been cleaned and it is cost-free from all moisture topic to the following circumstances and limitations:
(iv) Everlasting volumetric enlargement may not exceed 10 per cent of the full volumetric expansion at examination force.
S = Mc/I (iii) To determine the utmost longitudinal tensile tension due to hydrostatic examination pressure, the following system should be applied:
Cylinders with bottoms closed in by spinning should be subjected to a leakage check by placing the interior air or gas stress not to below the provider stress. Cylinders which leak should be rejected.
The restricting chemical composition of metal licensed by this specification must be as proven in table I of appendix A to this aspect.
