(1) No defect is permitted that is likely to weaken the completed cylinder appreciably. A fairly easy and uniform surface area end is necessary. The shell part has to be a reasonably real cylinder.
(two) A spun cylinder is one particular in which an finish closure in the completed cylinder has actually been welded via the spinning method.
(four) Decide porosity of filling and tare weights; verify compliance of marking with prescribed needs; get hold of essential copies of metal shell reviews prescribed in paragraph (b) of this section; and furnish comprehensive exam reports expected by this specification to the one who has accomplished the maker of your cylinders and, on request, into the purchaser.
(i) The remaining cylinders during the great deal need to be examined with the evidence strain, water-jacket, or direct expansion exam technique as prescribed in CGA C-1. The least take a look at pressure must be taken care of for the specific timeframe plus the tests equipment must be calibrated as prescribed in CGA C-1.
Cylinders needs to be manufactured utilizing tools and procedures satisfactory to make certain that each cylinder produced conforms to the requirements of the subpart.
The Office environment of the Federal Sign up publishes files on behalf of Federal companies but does not have any authority around their programs. We suggest you instantly Get hold of the agency linked to the written content in question.
Attachments for the container are licensed by fusion welding presented that these types of attachments are made of weldable stainless steel in accordance with paragraph (b) of this section.
Cylinders need to be produced working with equipment and processes ample making sure that each cylinder created conforms to the necessities of this subpart.
(ii) In using the “extension underneath load” approach, the total strain (or “extension less than load”) comparable to the tension at here which the 0.two per cent long lasting pressure happens might be established with adequate accuracy by calculating the elastic extension of your gauge length below correct load and adding thereto 0.
(ii) In using the “extension under load” technique, the entire pressure (or “extension underneath load”) corresponding to the stress at which the 0.2 p.c long lasting strain happens could possibly be decided with sufficient accuracy by calculating the elastic extension of your gauge size beneath ideal load and incorporating thereto 0.
(five) Every new design and style and any major alter to any appropriate design and style have to be competent for generation by tests prototype samples as follows:
(2) A manufacturer of the packaging subject matter to the requirements of this element is principally answerable for compliance with the necessities of the element. Nonetheless, anyone who performs a operate prescribed During this component shall accomplish that operate in accordance using this portion.
(ii) In using the “extension under load” technique, the full strain (or “extension beneath load”) similar to the worry at which the 0.two percent long lasting strain happens can be determined with enough accuracy by calculating the elastic extension of your gauge length underneath appropriate load and including thereto 0.
Screening is required on two (2) specimens removed from a person cylinder or component thereof taken at random out of each and every great deal of two hundred or much less. Samples needs to be taken out following heat therapy as illustrated in appendix A to this subpart.
