3.2.3 Manufacturing. The component raw materials shall be mixed, ground, and blended as required to
produce a product that is uniform, free from grit, lumps, skins, and floating pigment. The enamel shall be entirely
appropriate for the purpose intended and shall be in full conformance to the requirements of this specification.
3.2.4 Toxicity. When evaluated in accordance with 4.6, the enamel shall have no adverse effect on the health
of personnel when used for its intended purpose and shall not cause any environmental problems during waste
disposal (see 4.6 and 6.7). The materials used in the enamel, unless specific material maximum levels are cited
herein (see 3.2 and 3.3), shall have no known carcinogenic or potentially carcinogenic materials and shall have no
extremely hazardous substances (EHS) or toxic chemicals identified in 40 CFR 355 and 372.65, respectively. The
enamel shall not contain more than 0.005 percent cobalt compounds by weight in its formulation, unless a cobalt
drier is used (see table V). Questions pertinent to this effect shall be referred by the contracting activity to the
appropriate service medical department that will act as advisor to the contracting activity.
3.2.5 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally
preferable materials should be used to the maximum extent possible, provided that the material meets or exceeds the
operational and maintenance requirements, and promotes economically advantageous life cycle costs.
3.3 Quantitative requirements. The enamel shall conform to the quantitative requirements shown in table III
and as specified herein.
