It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of ast, limitations prior to use. If additional longitudinal strength is required, the use of other reinforcements, such as woven fabric, nonwoven unidirectional or bidirectional fabric, chopped-strand mat, or chopped strands, may be interspersed in the winding to provide additional strength.
NOTE 18—When tr is calculated to be 1? The minimum thickness of the radiused section shall be equal to the combined thickness of the shell wall and the bottom. A number in parentheses indicates the year of last reapproval. B Axial joint overlay widths shall be twice the width shown in table. Contact-molded laminates shall satisfy the minimum property requirements listed in Speci? Suitable methods include use of ultraviolet absorbers, astj of pigment of sufficient opacity in the outer dd resin-rich layer, or use of resins inherently resistant to ultraviolet degradation.

Workmanship, Finish, and Appearance 8. NOTE 16—Special vent sizing consideration should be given to the numerous operating situations that could otherwise cause a positive or 32999 negative pressure in a closed tank.
Included are requirements for materials, properties, design, construction, dimensions, tolerances, workmanship, and appearance. In environments that attack glass, the use of an organic-? Other test methods for determination of hoop properties may be used when the fabricator can verify the validity of the selected method.
Prior to hoisting the top end, a suitable protection pad of material should aztm placed under the bottom pivot point of tank so that as the tank rises, the strain is taken on the pad.
Installation laminate placements are shown in Fig.
This internal overlay shall not be considered a structural element in determining joint thickness. The bottom laminate surface shall be a hand-work? Link to Active This link will always route to the current Active version of the standard.
For Elliptical Bottom Head: Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Do not attempt to lift tank by attaching to other?

Since pigmentation makes inspection difficult, it shall be added after 3299 or otherwise 329 agreement between the purchaser and fabricator. Fluid level in the tank is an important consideration in the analysis. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
The thickness of the inner surface and interior layer 7. Current edition approved March 10, Larger nozzles, subject to superimposed mechanical forces, require special consideration.
It is the responsibility of the fabricator, using a thixotropic agent in the resin required for 7. Applies to manufacturing standards for Design Tanks contact-molded small- and medium-sized tanks. Where ladders are used inside and outsideall points of contact with the tank should be cushioned to protect the surface from scratching or point loading. The hoist wire should be connected to the top lifting lugs, and the tank should be raised carefully, using guide ropes to prevent sudden swinging.
Acceptable patterns of reinforcement placement are shown in Fig. As an alternative, a minimum of two passes of chopped roving of minimum length 0. A line of support is the following: NOTE 2—Gaskets shall be 1?
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Typical plate type and conical type gussets are shown in Fig. All woven roving, nonwoven fabric, and surfacing mat shall be overlapped.
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. Each ply of mat or pass asrm chopped roving shall be well-rolled prior to the application of v reinforcement. The three predominant standards today that relate to fiberglass tanks and vessels are: Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: Hold-down lugs should be grouted or shimmied to prevent excessive loads being transferred to the tank shell.
NOTE 20—A useful technique to check the cure of a non-molded surface of a polyester resin is as follows: PD t 5 2S 8 shell, or to join the bottom or top head to the shell, the thickness of the structural joint overlay shall be determined by the following equation, but shall not be less than 3? If damage has occurred, a claim should be? In either case, the resin used shall be that used in the equipment laminate and?
