C

16、lassification4.1 Tanks meeting this specification are classified accordingto type as follows, and it is the responsibility of the purchaserto specify the requirement for Type II tanks, the operatingpressure or vacuum levels, and the safety factor required forexternal pressure. Absence of a designati

17、on of type requiredshall imply that Type I is adequate.4.1.1 Type IAtmospheric pressure tanks vented directly tothe atmosphere, designed for pressure no greater or lower thanatmospheric.4.1.2 Type IIAtmospheric pressure tanks vented directlyinto a fume conservation system, and designed to withstand

18、thespecified positive and negative pressure not to exceed 14 in.(355.6 mm) of water when all tie-down lugs are properlysecured, in accordance with the fabricators recommendationsfor flat-bottom tanks.4.2 Tanks meeting this specification are classified accordingto grade as follows:4.2.1 Grade 1Tanks

19、manufactured with a single generictype of thermoset resin throughout.4.2.2 Grade 2Tanks manufactured with different generictypes of thermoset resin in the barrier and the structuralportion.NOTE 3The external corrosive environment due to spillage or corro-sive vapors should be considered when specify

20、ing Grade 2 tanks (see7.1.3.3).5. Materials and Manufacture5.1 ResinThe resin used shall be a commercial-grade,corrosion-resistant thermoset that has either been evaluated ina laminate by test in accordance with 11.3 or that has beendetermined by previous documented service to be acceptablefor the s

21、ervice conditions. Where service conditions have notbeen evaluated, a suitable resin also may be selected byagreement between fabricator and purchaser.5.1.1 The resin shall contain no pigment, dyes, colorants, orfiller, except as follows:5.1.1.1 A thixotropic agent that does not interfere withvisual

22、 inspection of laminate quality, or with the requiredcorrosion resistance of the laminate, may be added for viscos-ity control.NOTE 4The addition of a thixotropic agent may reduce the resistanceof many resin systems to certain corrosive chemical environments. It is theresponsibility of the fabricato

23、r, using a thixotropic agent in the resinrequired for 7.1.1 and 7.1.2, to ascertain its compatibility with thecorrosive environment when this has been reported to him by thepurchaser.5.1.1.2 Resin pastes used to fill crevices before overlay shallnot be subject to the limitations of 5.1.1.5.1.1.3 Res

24、in may contain pigment, dyes, or colorants whenagreed upon between fabricator and purchaser.NOTE 5The addition of pigment, dyes, or colorants may interfere withvisual inspection of laminate quality.5.1.1.4 Ultraviolet absorbers may be added to the exteriorsurface for improved weather resistance, if

25、agreed upon be-tween fabricator and purchaser.5.1.1.5 Antimony compounds or other fire-retardant agentsmay be added to halogenated resins for improved fire resis-tance, if agreed upon between fabricator and purchaser.NOTE 6Because the addition of fire-retardant agents may interferewith visual inspec

26、tion of laminate quality, they should not be used in theinner surface (7.1.1) or interior layer (7.1.2) unless their functionaladvantages would outweigh the loss of visual inspection.5.2 Reinforcement:5.2.1 Chopped-Strand MatChopped-strand mat shall beconstructed from chopped commercial-grade E-type

27、 glassstrands bonded together using a binder. The strands should betreated with a sizing that is chemically compatible with theresin system used.NOTE 7The selection of the particular chopped-strand mat is depen-dent upon the performance characteristics required of the finished productand upon the pr
