Interpretation of mechanical property data obtained from such specimens is discussed in Appendix X1. Ast, resin may require the addition of paraffin or may be sealed with overlaid? NOTE 1—The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment. This abstract is a brief summary of the referenced standard. The exterior surface shall also be fully cured. A Calculated thickness for design purposes is determined as follows: As an alternative, a minimum of two passes of chopped roving minimum?

Flexural strength, ultimate—22 psi MPa. Surface resin may require the addition of paraffin or may be sealed with overlaid film, as required or approved zstm the resin producer, to ensure proper surface cure. A number in parentheses indicates the year of last reapproval.
The abbreviation for reinforced thermoset plastic is RTP. NOTE 5—Maximum flame spread designation by Test Method E 84 relates to measurement and description of the properties of materials, products, or systems in response to heat and flame under controlled laboratory conditions and should not be considered or used for the description or appraisal of the fire hazard of materials, products, or systems under actual fire conditions.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate.
Pastes shall be made with thixotropic agents. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

D Test Method D A surfacing mat is not required unless specified. This specification is limited to fabrication by contact molding. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Tensile strength, ultimate—17 psi MPa. No plies may be omitted.
This section of the laminate shall be allowed to exotherm prior to application of subsequent plies of reinforcement. 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.
A thixotropic agent may be added to the resin for viscosity control. C Cut edges must be covered with resin. Tensile strength, ultimate— psi 62 MPa. A thixotropic agent may be added to the resin for viscosity control. Astm c wilfredo row Enviado por: The resin matrix is applied by various methods, including brush, roller, or spray gun.

This standard does not purport to address all of the safety concerns, if any, associated with astmm use. This specification covers composition, thickness, fabricating procedures, c5822 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.
C — When such items are required, limits for each shall be agreed upon between the fabricator and the buyer. Entrapped air or bubbles described are allowed, provided the surface cannot easily be broken with a pointed object, such as a knife blade.
Laminates shall be classified according to type, class, and grade: Additional desirable considerations in choosing a veil for a specific application include: Tensile modulus—1 psi MPa.
