Additional desirable considerations in choosing a veil for a specific application include: As an alternative, a minimum of two passes of chopped roving minimum? Originally published as C — 65 T. NOTE 1—The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment.
D Corrosion barrier Plies 1, 2, and 3 shall gel aetm structural plies are added.
C Corrosion barrier Plies 1, 2, and 3 shall gel before structural plies are added. 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. Lapped edges of adjacent v582 shall be staggered.
NOTE 9—Chemical resistance can be signi?

The resin matrix is applied by various methods, including brush, roller, or spray gun. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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.
Physical and Mechanical Properties 7. C — Pastes shall be made with thixotropic agents. 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.
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. Flexural strength, ultimate—22 psi MPa.
Consolidation of the composite laminate is by rolling. NOTE 6—The five Arabic grade numbers designate minimum physical property levels of a laminate obtained from tests of representative production process samples. This standard does not purport to address all of the safety concerns, if any, associated with its use.
NOTE 7—Table 1 and Table 2 are for reference 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 specification if they have been fully identified and characterized, as shown in Appendix X2.
Astm a Astm a Tensile modulus—1 psi MPa. C5582 Volume Flexural modulus— psi MPa. When such items are required, limits for each shall be agreed upon between the fabricator and the buyer. 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.
Tensile strength, ultimate—17 psi MPa. NOTE 8—The addition of? Tensile modulus—1 0 psi MPa. They are not arbitrarily selected values. 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version.
A thixotropic agent may be added to the resin for viscosity control. See Table 1 and Table 2 for standard thicknesses. No plies may be omitted. Flexural modulus—1 psi Aztm.

Link to Active This link will always route to the current Active version of the standard. 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.
Laminate designation from Table 3 shall consist of the abbreviation RTP followed by 1 type in Roman numerals; 2 class in capital letters followed by FS if required; 3 grade consisting of five Arabic numbers to designate minimum levels of physical properties and 4 thickness designated by Arabic number in decimal inches or ALL, if properties apply to asmt thicknesses.
However, results of this test may be used as elements of a? A superscript epsilon e indicates an editorial change since the last revision or reapproval.
