(i) Executing or witnessing the functionality in the chemical analyses on Each and every melt or Solid ton or other unit of starting up substance; or

(i) The remaining cylinders in Every good deal needs to be pressure tested via the proof pressure, water-jacket or immediate enlargement take a look at technique as prescribed in CGA C-one. The minimal exam strain has to be managed for the specific timeframe as well as the testing devices needs to be calibrated as prescribed in CGA C-1.

The completed cylinders have to be uniformly and adequately heated ahead of checks. Warmth cure with the cylinders of the licensed Evaluation needs to be as follows:

Chemical analyses and tests demanded by this subchapter must be made inside of the United States, Until usually permitted in composing by the Associate Administrator, in accordance with subpart I of section 107 of the chapter. Inspections and verification should be done by—

(i) If the chosen cylinder passes the drinking water-jacket or immediate expansion test, the remaining cylinders in Every single large amount has to be stress examined because of the proof tension h2o-jacket or immediate enlargement check strategy as prescribed in CGA C-1.

(two) If the porosity of each and every cylinder just isn't identified, a cylinder taken at random from loads of 200 or much less need to be analyzed for porosity. In case the exam cylinder fails, Each and every cylinder during the ton may very well be tested separately and those cylinders that pass the take a look at are suitable.

(b) A UN normal packaging for which the UN normal is ready forth In this particular element may be marked While using the United Nations symbol and various specification markings only if it completely conforms to the necessities of the element.

All spun cylinders and plugged cylinders must be analyzed for leakage by gasoline or air pressure after The underside has become cleaned which is totally free from all dampness subject to the subsequent conditions and limitations:

(ii) In using the “extension beneath load” method, the whole strain (or “extension beneath load”) equivalent to the worry at which the 0.two percent long term pressure happens could be established with adequate precision by bar178 slot calculating the elastic extension in the gauge length beneath suitable load and incorporating thereto 0.

Together with the necessities of § 178.35, the inspector's report to the Actual physical test report, will have to reveal the average price for 3 specimens along with the minimum value for a person specimen for every good deal amount.

(iii) Straight threads, obtaining at the least 4 engaged threads, to possess restricted in shape and calculated shear power at the least ten periods the examination force in the container; gaskets needed, satisfactory to prevent leakage.

(two) A spun cylinder is a person wherein an conclude closure inside the concluded cylinder is welded by the spinning system.

(two) A spun cylinder is 1 wherein an end closure in the concluded cylinder has long been welded from the spinning approach.

A person completed cylinder picked at random out of every great deal of 500 or fewer successively manufactured have to be hydrostatically analyzed to four
