Contact-Molded Glass-Fiber-Reinforced Thermoset Resin
This standard is issued under the fixed designation D 4097; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1.1 This specification covers cylindrical tanks fabricated by
contact molding for above-ground vertical installation, to
contain aggressive chemicals at essentially atmospheric pressure, and made of a commercial-grade polyester or vinyl ester,
resin. Included are requirements for materials, properties,
design, construction, dimensions, tolerances, workmanship,
1.2 This specification does not cover the design of vessels
intended for pressure above hydrostatic, vacuum conditions,
except as classified herein, or vessels intended for use with
liquids heated above their flash points.
1.3 The values given in parentheses are provided for information purposes only.
NOTE 1—Special design consideration should be given to vessels
subject to superimposed mechanical forces, such as earthquakes, wind
load, or agitation, to vessels subject to service temperature in excess of
180°F (82°C), and to vessels with unsupported bottoms.
NOTE 2—There is no similar or equivalent ISO standard.
1.4 The following safety hazards caveat pertains only to the
test method portion, Section 11, of this specification: This
the standard does not purport to address all of the safety concerns,
if any, associated with its use. 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.
