(i) The remaining cylinders in each whole lot needs to be analyzed from the proof force, water-jacket, or immediate expansion examination method as prescribed in CGA C-1. The minimal test stress needs to be preserved for the specific timeframe plus the testing products need to be calibrated as prescribed in CGA C-one.
Mechanical tests needs to be executed to find out produce strength, tensile toughness, elongation like a percentage, and reduction of place of material as a percentage, as follows:
(four) Ascertain porosity of filling and tare weights; validate compliance of marking with prescribed prerequisites; acquire important copies of metal shell reviews prescribed in paragraph (b) of the segment; and furnish finish check stories expected by this specification to the one who has accomplished the manufacturer from the cylinders and, upon ask for, to the purchaser.
(ii) In utilizing the “extension under load” technique, the entire strain (or “extension beneath load”) corresponding to the pressure at which the 0.two per cent long lasting pressure occurs could be established with enough accuracy by calculating the elastic extension from the gauge duration underneath proper load and including thereto 0.
(i) Minimum thickness of heads and bottoms has to be not less than ninety percent of your necessary thickness of the facet wall.
Cylinders has to be made utilizing products and processes enough in order that Each and every cylinder produced conforms to the necessities of this subpart. No fissure or other defect is permitted that is likely to weaken the concluded cylinder appreciably. A reasonably sleek and uniform area finish is required. If not at first free of charge from these types of defects, the area may very well be machined or or else handled to eradicate these defects.
(one) The attachment into the tops or bottoms of cylinders of neckrings, footrings, handlers, bosses, pads, and valve protecting rings is approved delivered that this kind of attachments and also the percentage of the container to which they are hooked up are made of weldable metal, the carbon content material of which can not exceed 0.twenty five %.
(B) With information specifying the sort(s) and Proportions on the closures, which include gaskets and another parts required in order that the packaging is effective at properly passing the relevant general performance tests. This information need to incorporate any strategies to get followed, like closure Guidance for interior packagings and receptacles, to successfully assemble and close the packaging for the purpose of avoiding leakage in transportation.
You'll be able to e mail the location owner to allow them to know you ended up blocked. Be sure to include Everything you were being accomplishing when this website page arrived up as well as the Cloudflare Ray ID discovered at the bottom of the page.
A root bend exam specimen need to be faraway from the cylinder or welded test plate utilized for the tensile examination specified in paragraph (m)(1) of the section. Specimens has to be taken from over the longitudinal seam and needs to be well prepared and examined in conformance with the requirements of CGA C-3.
(iii) When dimension of cylinder won't allow securing straight specimens, the specimens may be taken in almost any place or path and will be straightened or flattened cold, by stress only, not by blows.
(2) A spun cylinder is a person in which an conclusion closure inside the completed cylinder continues to be welded via the spinning approach.
(i) A gauge length of at least 24 occasions the thickness using a width not about 6 occasions the thickness. The specimen, unique of grip finishes, will not be flattened. Grip finishes may be flattened to inside of a person inch of each and every conclude of the diminished segment. When size of cylinder does not permit securing straight specimens, the specimens might be taken in almost any spot or path and could be straightened or flattened cold by tension only, not by blows.
suggests the person whose identify here and tackle or symbol appears as Portion of the specification markings necessary by this element or, for any packaging marked With all the image of the acceptance agency, the person on whose behalf the acceptance company certifies the packaging.
