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 applications. 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, thixotropic 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.

TABLE 1 Requirements for Type I, Grade 1, Epoxy Resin

Class	Epoxy Content		Viscosity, cP at 25°C	Mettler Softening Point, °C	Color^A Gardner- Holdt, max
Class	Equivalents/100 g	WPE^B	Viscosity, cP at 25°C	Mettler Softening Point, °C	Color^A Gardner- Holdt, max
A^C	0.500 to 0.588	170 to 200	3000 to 20 000		3
B	0.443 to 0.527	190 to 226	15 000 to 40 000		5
C	0.357 to 0.443	226 to 280	←--------- semi-solid --------→		5
D	0.125 to 0.357	280 to 800		40 to 90	5
E	0.067 to 0.125	800 to 1500		90 to 110	5
F	0.040 to 0.067	1500 to 2500		110 to 140	5
G	0.017 to 0.040	2500 to 6000		134 to 180	6
H	0.010 to 0.020	5000 to 10 000		160 to 200	7

^A Test Method D1209 with a maximum color of 100 defines low color Type I resins.

^B WPE = weight per epoxy equivalent.

^C Can exist as a supercooled liquid.

TABLE 2 Requirements for Type I, Grade 2, Epoxy Resin

Class	Epoxy Content	Viscosity, cP at 25°C
A	^A	100 to 500
B	^A	500 to 900
C	^A	900 to 4000
D	^A	4000 to 10 000

^A The WPE of these diluted resins shall be agreed upon between the purchaser and the seller.

1.3 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 appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.4 The values stated in SI units are to be regarded as standard.

Note 1-ISO 3673-1:1980(E) is similar but not equivalent to this specification. Product classification and characterization are not the same.
