Designation:D1763–00(Reapproved2005)
Standard Specification for
Epoxy Resins1
This standard is issued under thefixed designation D1763;the number immediately following the designation indicates the year of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon(e)indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1.Scope
1.1This specification covers totally reactive epoxy resins supplied as liquids or solids which can be used for castings, coatings,tooling,potting,adhesives,or reinforced applica-tions.The addition of hardeners in the proper proportions causes these resins to polymerize into infusible products.The properties of these products can be modified by the addition of variousfillers,reinforcements,extenders,plasticizers,thixotro-pic agents,etc.The epoxy resins described also can be used as stabilizers and cross-linking agents;and they can be combined with other reactive products.
1.2It is not the function of this specification to provide engineering data or to guide the purchaser in the selection of a material for a specific end use.Ordinarily the properties listed in Table1and Table2are sufficient to characterize a material under this specification,and it is recommended that routine inspection be limited to testing for such properties.
1.3This standard does not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.
1.4The values stated in SI units are to be regarded as standard.
N OTE1—ISO3673–1:1980(E)is similar but not equivalent to this specification.Product classification and characterization are not the same.2.Referenced Documents

4.1.1Type I —Bisphenol A and epichlorohydrin.
4.1.2Type II —Reaction product of phenol and formalde-hyde (novolac resin)and epichlorohydrin.
4.1.3Type III —Cycloaliphatic and peracid epoxies.4.1.4Type IV —Glycidyl esters.
4.1.5Type V —Reaction product of epichlorohydrin and p -aminophenol.
4.1.6Type VI —Reaction product of epichlorohydrin and glyoxal tetraphenol.
4.2These types may be further subdivided by grades:4.2.1Grade 1—Resins containing no diluent.
4.2.2Grade 2—Resins modified with a reactive diluent.Each class of Grade 2resin can be made from any class of Grade 1resin.
4.2.3Each grade may include as many classes as are shown in the tables.
5.Requirements
5.1The resin shall be of uniform quality and as free of contamination as can be achieved by good manufacturing practice.
5.2The resin shall conform to the requirements prescribed in Tables 1-7for the type,grade,and class of material specified.
6.Sampling
6.1Take a representative sample sufficient for the test specified either from a well-blended bulk lot prior to packaging or by withdrawing samples with a thief from no less than 5%of the containers comprising the lot or shipment.
6.2Unless the samples taken from the containers show evidence of variability,blend them into a single composite sample on which to conduct the specified tests.Instead of the foregoing,adequate statistical sampling acceptable to the purchaser and the seller may be substituted.
7.Test Methods
7.1Determine compliance with the requirements specified in Table 1in accordance with the following methods:
