There is no known ISO equivalent to this standard. Dimensions and Tolerances 8. The customer receives a tank that exceeds the standard! NOTE astj over 6 ft 1.
The all-interior installation laminate placement is used only when the nozzle being awtm has an integral conical gusset preventing application of an exterior laminate. The reinforcement thickness shall be equal to the thickness of the head as calculated above. The d399 of these requirements is to avoid orienting joints in reinforcing layers perpendicular to the maximum load-bearing direction circumferential.
Damage caused by such action may result in cracking the inner corrosion-resistant liner, as well as the structural portion of the tank.

NOTE 21—The use of organic reinforcing materials may reduce the Barcol hardness readings without necessarily indicating undercure. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
NOTE 11—Tanks with unsupported bottoms require special design consideration. NOTE 6—Because the addition of? ASME RTP-1 As a custom manufacturer specializing in meeting the unique needs of our customers, our exposure to these different standards is much higher than for the manufacturer that produces a cookie cutter tank.
This standard has been approved for use by agencies of the Department of Defense.
A number in parentheses indicates the year of last reapproval. Minimum vent size shall be sufficient to handle the? Prior to hoisting the top end, a suitable protection pad of material should be placed under the bottom pivot point of tank so that as the tank rises, the strain is taken on the pad.

NOTE 22—Barcol hardness values may vary when tests are conducted at temperatures that differ from those shown in Only those constructions evaluated for design properties in This standard does not purport to address all of the safety concerns, if any, associated with its use. NOTE 5—The addition of pigment, dyes, or colorants may interfere with visual inspection of laminate d32999. The hoist wire should be connected to the top d399 lugs, and the tank should be raised carefully, using guide ropes to prevent sudden swinging.
