(a) Every packaging represented as made to some DOT specification or even a UN common must be marked over a non-removable element with the packaging with specification markings conforming for the applicable specification, and with the subsequent:

Cylinders have to be produced using tools and procedures ample to make sure that Every single cylinder made conforms to the necessities of this subpart.

mean the packaging identification markings demanded by this section which includes, wherever relevant, the title and address or symbol in the packaging maker or approval company.

Repairs of turned down cylinders is authorized. Cylinders that are leaking have to be rejected, other than that:

Reheat treatment of rejected cylinders is licensed. Subsequent thereto, cylinders have to move all prescribed exams to become suitable. Repair by welding or spinning is just not licensed.

(iii) The least exam strain need to be taken care of at the very least 30 seconds and adequately lengthier to be sure complete enlargement. Any interior tension used after heat-cure and before the Formal check might not exceed 90 p.c with the examination force.

(i) The remaining cylinders in Just about every good deal have to be tested because of the proof tension, water-jacket, or direct growth test strategy as prescribed in CGA C-one. The minimal test stress needs to be maintained for the particular timeframe and also the screening machines should be calibrated as prescribed in CGA C-1.

(ii) In using the “extension less than load” technique, the overall strain (or “extension beneath load”), corresponding to the tension at which the 0.2 per cent lasting pressure occurs may very well be identified with sufficient accuracy by calculating the elastic extension on the gauge length below acceptable load and introducing thereto 0.

A specimen need to be faraway from one cylinder of every wide range of 200 or fewer, or welded check plate. The welded take a look at plate has to be of one of many heats during the large amount of 200 or fewer which it represents, in a similar condition and around a similar thickness click here given that the cylinder wall other than that in no case must it's of the lesser thickness than that necessary for a quarter size Charpy impression specimen. The weld should be created by the same strategies and subjected to the identical heat therapy as the main weld within the cylinder.

(iii) When measurement of your cylinder isn't going to permit securing straight specimens, the specimens may very well be taken in almost any area or course and will be straightened or flattened chilly, by force only, not by blows.

Products need to be determined by any appropriate strategy besides that plates and billets For warm-drawn containers have to be marked with the heat selection.

(iii) With a cylindrical part of the shell that extends further than the recessed bottom of your cylinder constituting an integral and non-strain part of the cylinder.

(2) The inspector need to verify ultrasonic inspection of all substance by inspection or by getting the material producer's certification of ultrasonic inspection. Ultrasonic inspection have to be done or verified as getting been executed in accordance with paragraph (b)(five) of this section.

(iii) On the cylindrical portion of the shell that extends past the recessed bottom from the cylinder, constituting an integral and non-stress A part of the cylinder;
