C Corrosion barrier Plies 1, 2, and 3 shall gel before structural plies are added. This standard does not purport to address all asfm the safety concerns, if any, associated with its use. NOTE 1—The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment.
In combination with the cured resin, the surfacing veil helps determine the thickness of the resin-rich layer, reduces microcracking, and provides a nonwicking chemically resistant layer. NOTE 7—Table 1 and Table 2 are for reference purposes and do not preclude other laminate-type constructions, c82 as nonwoven biaxial or unidirectional fabric, which may be agreed upon between the buyer and the seller, or may be added to this specification if they have been fully identified and characterized, as shown in Appendix X2.
Physical and Mechanical Properties 7. Tensile strength, ultimate—17 psi MPa. However, results of this test may be used as elements of a fire risk assessment that takes into account all the factors that are pertinent to an assessment of the fire hazard or a particular end use. Workmanship and Finish 9. A thixotropic agent may be added to the resin for viscosity control. A superscript epsilon e indicates an editorial change since the last revision or reapproval. NOTE 11—Thicker laminates shall not be used for such tests, as results will vary signi?

NOTE 6—The five Arabic grade numbers designate minimum physical property levels of a laminate obtained from tests of representative production process samples. D Corrosion barrier Plies 1, 2, and 3 shall gel before structural plies are added.
NOTE 9—Chemical resistance can be signi? It is qstm only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
The exterior surface shall also be asmt cured. Tensile modulus—1 0 psi MPa. D Foreign matter must not penetrate the surface and must not contribute to entrapped air or other defects not allowed. For 5 by 4 square satm roving, the approximate relationship is shown in Fig.
In combination with the cured resin, the surfacing veil helps determine the thickness of the resin-rich layer, reduces microcracking, and provides a nonwicking chemically resistant layer.
Test Method D See Table 1 and Table 2 for standard thicknesses. Laminates atm be classified according to type, class, and grade: 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.
Roll each ply for thorough wet-out and deaeration. Each pass of chopped roving or ply of chopped-strand mat shall be thoroughly rolled out. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Pastes shall be made with thixotropic agents. Additional desirable considerations in choosing a veil for a speci? The resin matrix is applied by various methods, including brush, roller, or spray gun.
Interpretation of mechanical c5882 data obtained from such specimens is discussed in Appendix X1. C — Tensile strength, ultimate— psi 62 MPa. The final ply shall be mat or chopped roving equivalent. Next apply the speci?
