Where service conditions have not been evaluated, a suitable resin also may be selected by agreement between fabricator and purchaser. Larger nozzles, subject to superimposed mechanical forces, require special consideration. Other test methods for determination of sstm properties may be used when the fabricator can verify the validity of the selected method.

All woven roving, nonwoven fabric, and surfacing mat shall be overlapped. Minimum vent size shall be sufficient to xstm the? Each successive ply or pass of reinforcement shall be well-rolled prior to the application of additional reinforcement.

Included are requirements for materials, properties, design, construction, dimensions, tolerances, workmanship, and appearance. The interior overlay shall asrm the same corrosion resistance to the? What are Design Tanks manufacturing standards? Do not attempt to lift tank by attaching to other? In either case, the resin used shall be that used in the equipment laminate and?

The strands should be treated with a sizing that is chemically compatible with the resin system used. Includes requirements for materials, properties, axtm, construction, dimension, tolerance, workmanship, and appearance. The use of woven roving is optional. The entire roughened area shall be coated with paraffinated resin after the joint lay-up is made. Do not attach lifting devices to any?


If the surface becomes softened or tacky, it is and indication of under cure. Damage caused by atsm action may result in cracking the inner corrosion-resistant liner, as well as the structural zstm of the tank. Absence of a designation of type required shall imply that Type I is adequate. NOTE 16—Special vent sizing consideration should be given to the numerous operating situations that could otherwise cause a positive or a negative pressure in a closed tank.

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. Hoisting equipment operators should attach a guide line to prevent tank from swinging out of control. Originally published as D — Instrument calibration and method shall be as described in Test Method D The result is a quality product with a very low incidence of tank failure.

Fluid level in the tank is an important consideration in the analysis. The reinforcement shall then taper into the side wall over an additional length of 4 in.

The tank shall be secured to the cradles or skid so that there can be no movement of the tank in relation to the skid or cradle under normal handling.

Nozzle Inside Diameter Up to 10 in. NOTE 8—The use of an accepted analytical technique, such as laminated plate theory LPTfor design and analysis of composite vessels may predict stresses, strains, and strength on a ply-by-ply basis, given some basic lamina properties.

The thickness of the? The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. This abstract is a brief summary of the referenced standard. NOTE 21—The use of organic reinforcing materials may reduce the Barcol hardness readings without necessarily indicating undercure.


The customer receives a tank that exceeds the standard! The Design Tanks Difference: Overall thickness, mm h shear lengthmm A 14? For the convenience of the user, Committee D has highlighted those changes that may impact the use of 33299 test method. Last previous edition D — 95ae1.

Link to Active This link will always route to the current Active version aztm the standard. Laminate Construction Requirements 7. Surfaces shall be clean and dry before lay-up. Where shape, thickness, or other restrictions preclude covering the edges with the preceding laminate, such cut edges and any machined?

The intent of these requirements is to avoid orienting joints in reinforcing layers perpendicular to the maximum load-bearing direction circumferential. The glass content of the separated sample shall be determined in accordance with Test Method D NOTE 10—Tanks with signi?

The cradles or skid shall be padded and secured to the bed of the vehicle in such a manner that will prevent damage to the tank with normal handling. This internal overlay shall not be considered a structural element in determining joint thickness. NOTE 22—Barcol hardness values may vary when tests are conducted at temperatures that differ from those shown in
