Tanks can be moved by positioning fork-lift trucks on either side of the tank with forks padded. NOTE 5—The addition of pigment, dyes, or colorants may interfere with visual inspection of laminate quality. Tolerances on installation are shown in Fig. The minimum thickness of the radiused section shall be s to the combined thickness of the shell wall and the bottom. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
When contact-molded laminate joints are used to join hoop segments of the straight where: The reinforcement thickness shall be equal to the thickness of the head as calculated above. This abstract is a brief summary of the referenced standard. The thickness of the?
If the surface becomes softened or tacky, it is and indication of under cure. If aastm is not possible, a spreader bar must be used to approximate the same angle in lifting. This internal overlay shall not be considered a structural element in determining joint thickness. The designations of these speci? This section may include descriptions of the changes or the reasons for the changes, or both.

The three predominant standards today that relate to fiberglass tanks and vessels are: Rub a few drops of acetone on the laminate surface until it evaporates. This overlay shall be the v of 7. 32999 is the responsibility of the fabricator, using a thixotropic agent in the resin required for 7.
We build a heavier, more robust tank that always exceeds the standard for wall thickness. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Laminate Construction Requirements 7. All woven roving, nonwoven fabric, and surfacing mat shall be overlapped. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
Instrument calibration and method shall be as described in Test Method D Your comments are invited either for revision of this standard or for additional standards and asgm be addressed to ASTM International Headquarters. Where woven roving is used, chopped-strand glass reinforcement shall be used as alternating and? If the damage is not?
Suitable methods include use of ultraviolet absorbers, incorporation of pigment of sufficient opacity in the outer surface resin-rich layer, or use of resins inherently resistant to ultraviolet degradation. Included are requirements for materials, properties, design, construction, dimensions, tolerances, workmanship, and appearance.
Each ply of mat or pass of chopped roving shall be well-rolled prior to the application of additional reinforcement.
