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. This specification covers composition, thickness, fabricating procedures, and physical property requirements for glass fiber reinforced thermoset polyester, vinyl ester, or other qualified thermosetting resin laminates comprising the materials of construction for RTP corrosion-resistant tanks, piping, and equipment.
NOTE 7—Table 1 and Table 2 are for aetm purposes and do not preclude other laminate-type constructions, such as nonwoven biaxial or unidirectional fabric, which may be agreed upon between the buyer and the seller, or may be added to this speci? As an alternative, a minimum of two passes of chopped roving minimum fiber length 1 in.
A superscript epsilon atm indicates an editorial change since the last revision or reapproval. D Test Method D Pastes shall be made with thixotropic agents. This standard does not purport to address all of the qstm concerns, if any, associated with its use. Each pass of chopped roving or ply of chopped-strand mat shall be thoroughly rolled out.
A Maximum dimensions 2 in. Lapped edges of adjacent layers shall be staggered. Interpretation of mechanical property data obtained from such specimens is discussed in Appendix X1. Plastics and is the direct responsibility of Subcommittee D As an alternative, a minimum of two passes of chopped roving minimum?
Gaps are not permitted. They are not arbitrarily selected values. Each pass asm chopped roving or ply of chopped-strand mat shall be thoroughly rolled out.
When such items are required, limits for each shall be agreed upon between the fabricator and the buyer. Tensile modulus—1 0 psi MPa. This standard is issued under the fixed designation C ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
Flexural strength, ultimate—2 0 psi MPa. This standard does not purport to address all of the safety concerns, if any, associated with its use. Flexural modulus—1 psi MPa. Current edition approved Oct. Entrapped air or bubbles described are allowed, provided the surface cannot easily be broken with a pointed object, such as a knife blade.
A number in parentheses indicates the year of last reapproval. In Type II laminates the woven roving is to be laid square, and test specimens are to be cut parallel to the warp rovings. NOTE 6—The five Arabic grade numbers designate minimum physical property levels of a laminate obtained from tests of representative production process samples.

Additional desirable considerations in choosing a veil for a specific application include: A thixotropic agent may be added to the resin for viscosity control. Link to Active This link will always route to the current Active version of the standard. 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.
Flexural strength, ultimate—18 psi MPa.
They are not arbitrarily selected values. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Surfacing mat shall be butted together or have overlaps no more than 1? 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.
Consolidation of the composite laminate is by rolling. D Foreign matter must not penetrate the surface and must not contribute to entrapped air or other defects not allowed.
Location of exotherm plies may be shifted within the laminate body. No plies may be omitted. Test Method D The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
ASTM C582 – 09(2016)
Pastes shall be made with thixotropic agents. These products shall be a commercial grade of E-type glass fiber with a sizing that is compatible with the resin. Calculated thickness for design purposes is determined as follows: C — Standard Speci? Lapped edges of adjacent layers shall asfm staggered. B Calculated thickness for design purposes is determined as follows: Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate.
A surfacing mat is not required unless speci? C Cut edges must be covered with resin. qstm
A Calculated thickness for design purposes is determined as follows: The abbreviation for reinforced thermoset plastic is RTP.
