(iv) Lasting volumetric expansion may well not exceed ten p.c of the overall volumetric expansion at test pressure.
(two) Each opening in the spherical kind of cylinder must be delivered that has a fitting, manager, or pad of weldable steel securely connected on the cylinder by fusion welding.
(1) Just about every stress specimen have to have a gauge length of two inches by using a width not exceeding just one and a single-50 % inches. Aside from the grip ends, the specimen may not be flattened. The grip ends may be flattened to within just one inch of each stop of the diminished segment.
Cylinders must be produced employing gear and procedures adequate to make certain Just about every cylinder created conforms to the requirements of this subpart. No defect is permitted that is probably going to weaken the finished cylinder appreciably.
(iii) For the objective of pressure measurement, the initial pressure need to be established when the specimen is below a stress of twelve,000 psi plus the strain indicator looking at getting set in the calculated corresponding strain.
You could e mail the location owner to allow them to know you were blocked. Remember to incorporate Whatever you were accomplishing when this page came up and also the Cloudflare Ray ID uncovered at The underside of the web site.
(iv) Everlasting volumetric growth may not exceed ten p.c of the total volumetric enlargement at test force.
(i) The remaining cylinders while in the whole lot should be examined from the proof force, h2o-jacket, or direct enlargement take a look at method as prescribed in CGA C-1. The minimum amount exam force have to be maintained for the specific timeframe and the screening tools needs to be calibrated as prescribed in CGA C-1.
(iii) For the purpose of strain measurement, the initial pressure reference must be established although the specimen is underneath a tension of 12,000 psi plus the strain indicator looking through remaining established on the calculated corresponding pressure.
(i) The remaining cylinders in Every single great deal must be analyzed because of the evidence stress drinking water-jacket or immediate expansion check approach as prescribed in CGA C-one. The minimum examination pressure needs to be taken care of for the particular timeframe and also the testing products need to be calibrated as prescribed in CGA C-one.
(iii) The bare minimum check tension should be preserved at the very least 30 seconds and adequately extended to make sure finish growth. Any internal stress used right after heat-remedy and just before the official examination may well not exceed ninety per cent on the check pressure.
(two) A company of a packaging topic to the requirements of this element is mainly accountable for compliance with the necessities of the element. However, any person who performs a operate prescribed In this particular element shall conduct that function in accordance using this type of section.
(ii) A person specimen must be taken from both head on a cylinder when both of those heads are made of exactly the same material. On the other hand, if the two heads are made of differing products, a specimen check here have to be taken from each head.
suggests the individual whose title and handle or image appears as Portion of the specification markings demanded by this part or, to get a packaging marked with the image of the acceptance agency, the individual on whose behalf the acceptance company certifies the packaging.
