1. Scope
1.1 This 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 various fillers, reinforcements, extenders, plasticizers, thixo- tropic 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. 1.2 It 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 Table 1 and Table 2 are sufficient to characterize a material under this specification, and it is recommended that routine inspection be limited to testing for such properties. 1.3 The values stated in SI units are to be regarded as standard. N OTE 1—ISO 3673–1:1980(E) is similar but not equivalent to this specification. Product classification and characterization are not the same. 1.4 This 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, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.5 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
4. Classification
4.1 The resins covered contain no hardeners. Resin types covered are divided into specific groups by their chemical nature: 4.1.1 Type I—Bisphenol A and epichlorohydrin. 4.1.2 Type II—Reaction product of phenol and formalde- hyde (novolac resin) and epichlorohydrin. 4.1.3 Type III—Cycloaliphatic and peracid epoxies. 4.1.4 Type IV—Glycidyl esters. 4.1.5 Type V—Reaction product of epichlorohydrin and p-aminophenol.4.1.6 Type VI—Reaction product of epichlorohydrin and glyoxal tetraphenol. 4.2 These types may be further subdivided by grades: 4.2.1 Grade 1—Resins containing no diluent. 4.2.2 Grade 2—Resins modified with a reactive diluent. Each class of Grade 2 resin can be made from any class of Grade 1 resin. 4.2.3 Each grade may include as many classes as are shown in the tables.
5. Requirements
5.1 The resin shall be of uniform quality and as free of contamination as can be achieved by good manufacturing practice. 5.2 The resin shall conform to the requirements prescribed in Tables 1-7 for the type, grade, and class of material specified.
6. Sampling
6.1 Take 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. 6.2 Unless 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
7.1 Determine compliance with the requirements specified in Table 1 in accordance with the following methods: 7.1.1 Viscosity—Test Method D445. 7.1.2 Weight per Epoxy Equivalent—(WPE)—Test Method D1652. 7.1.3 Color—Test Method D1544, except for Classes IV through VII, where a 40 % solids solution in butyl carbitol shall be used. 7.1.4 Color—Test Method D1209 is used to characterize the low color Type I and Type III resins. 7.1.5 Softening Point—Test Method D3104.
