Tensile strength, ultimate—17 psi MPa. No plies may be omitted. Current edition approved Oct. 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. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Because it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate.

For 5 by 4 square weave roving, the approximate relationship is shown in Fig. A Calculated thickness for design purposes is determined as follows: D Corrosion barrier Plies 1, 2, and 3 shall gel before structural plies are added. A number in c52 indicates the year of last reapproval. 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.

C Corrosion barrier Plies 1, 2, and 3 shall gel before structural plies are added. Each pass of chopped roving or ply of chopped-strand mat shall be thoroughly rolled out.

Flexural strength, ultimate—22 psi C528.

As an alternative, a minimum of two passes of chopped roving minimum fiber length 1 in. In Type II laminates the woven roving is to be laid square, and test specimens are to be cut parallel to the warp rovings. However, results of this test may be used as elements of a?

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Flexural strength, ultimate—18 psi MPa. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Plastics and is the direct responsibility of Subcommittee D 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.

This section of the laminate shall be allowed to exotherm prior to application of subsequent plies of reinforcement. NOTE 1—The laminates covered by this specification are manufactured during fabrication of contact-molded RTP tanks, piping, and other equipment.

Lapped edges of adjacent layers shall be staggered. They are not arbitrarily selected values. B Calculated thickness for design purposes is determined as follows: The abbreviation for reinforced thermoset plastic is RTP.

They are not arbitrarily selected values. NOTE 6—The five Arabic grade numbers designate minimum physical property levels of a laminate obtained from tests of representative production process samples.

ASTM C582 – 09(2016)

This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

Additional desirable considerations in choosing a veil for a speci? Pastes shall be made with thixotropic agents. Next apply the speci? Parte 1 de 2 Standard Specification for Contact-Molded Reinforced Thermosetting Plastic RTP Laminates for Corrosion-Resistant Equipment1 This standard is issued aetm the fixed designation C ; the number immediately following the designation indicates the sstm of atm adoption or, in the case of revision, the year of last revision.

Location of exotherm plies may be shifted within the laminate body. 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. Tensile modulus—1 psi MPa. Tensile strength, ultimate— psi 62 MPa.
