ASTM C582 – 09(2016)
Flexural strength, ultimate—22 psi MPa. A thixotropic agent may be added to the resin for viscosity control. See Table 1 and Table 2 for standard thicknesses. Calculated thickness astj design purposes is determined as follows: Additional desirable considerations in choosing a veil for a specific application include: This specification is limited to fabrication by contact molding. This section of the laminate shall be allowed to exotherm prior to application of subsequent plies of reinforcement.
The abbreviation for reinforced thermoset plastic is RTP. 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. Lapped edges of adjacent layers shall be staggered. Originally published as C — 65 T.
In all cases only the current version of the standard as published by ASTM is to be considered the official document. Gaps are not permitted. They are not arbitrarily selected values.

When such items are required, limits for each shall be agreed upon between aatm fabricator and the buyer. Pastes shall be made with thixotropic agents. Surfacing mat shall be butted together or have overlaps no more than 1? Flexural modulus— 0 psi MPa.
This abstract is a brief summary of the referenced standard. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
NOTE 6—The five Arabic grade numbers designate minimum physical property levels of a laminate obtained from tests of representative production process samples.
The final ply shall be mat or chopped roving equivalent. NOTE 8—The addition of? 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. Surface resin may require the addition of paraffin or may be sealed with overlaid film, as required or approved by the resin producer, to ensure proper surface cure.
The initial ply of the following lamination shall be 11? 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. 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.
NOTE 11—Thicker laminates shall not be used for such tests, as results will vary signi? See Table 1 and Table 2 for standard thicknesses. Tensile strength and tangent modulus of elasticity, flexural strength, glass content, thickness, hardness, chemical resistance, and surface flame-spread classification tests shall be performed to conform to the specified requirements.
