(iii) When dimension of cylinder won't allow securing straight specimens, the specimens might be taken in any site or direction and may be straightened or flattened cold, by strain only, not by blows.
Before any check, all cylinders has to be subjected to a solution heat remedy and ageing treatment method appropriate for the aluminum alloy employed.
(1) A tension, approximately the same as although not lower than the provider stress, should be placed on just one facet with the completed bottom over a place of a minimum of 1⁄sixteen of the total spot of the bottom although not lower than 3⁄4 inch in diameter, such as the closure, for at least one moment, all through which period the opposite facet of The underside subjected to force should be lined with h2o and closely examined for indications of leakage.
(i) The remaining cylinders within the lot have to be tested because of the proof force, water-jacket, or immediate enlargement take a look at method as prescribed in CGA C-1. The minimal exam strain needs to be taken care of for the precise timeframe along with the tests tools needs to be calibrated as prescribed in CGA C-1.
(i) If the chosen cylinder passes the water-jacket or immediate expansion test, the remaining cylinders in Each individual ton have to be stress analyzed through the proof force water-jacket or immediate growth test system as prescribed in CGA C-1.
The Business office with the Federal Sign-up publishes files on behalf of Federal organizations but doesn't have any authority about their courses. We recommend you instantly contact the company associated with the content in dilemma.
(iii) For the goal of strain measurement, the First pressure need to be set while the specimen is beneath a strain of twelve,000 psi, and the strain indicator looking through need to be established at the calculated corresponding strain.
(iii) In the event the dimensions of a cylinder isn't going to allow securing straight specimens, the specimens might be taken in almost any area or route and may be straightened or flattened chilly, by force only, not by blows.
(ii) In using the “extension below load” technique, the total strain (or “extension below load”), akin to the strain at which the 0.two per cent long term strain takes place may very well be decided with adequate accuracy by calculating the elastic extension of the gauge duration underneath acceptable load and including thereto 0.
A root bend examination specimen have to be removed from the cylinder or welded examination plate employed for the tensile take a look at laid out in paragraph get more info (m)(1) of this area. Specimens has to be taken from over the longitudinal seam and have to be geared up and analyzed in conformance with the necessities of CGA C-three.
