3.4.4 Toxicity. The materials used in the coating compound, unless specific material maximum levels are cited
herein (see 3.4.2 and 3.4.3), shall have no known carcinogenic or potentially carcinogenic materials identified by
OSHA (29 CFR 1990) as regulated carcinogens, or IARC latest monographs, or the latest annual report of the NTP;
and shall have no extremely hazardous substances (EHS) or toxic chemicals identified in 29 CFR 1910.1000, 40
CFR 355, and 40 CFR 372, respectively. The manufacturer is responsible for maintaining carcinogenic free,
extremely hazardous substance free, and toxic chemical free materials. The manufacturer shall not, unless specific
material maximum levels are cited herein, allow the addition of any of these prohibited materials to the formulation;
and when any of these prohibited materials are/may be present, as a result of being present as a trace or impurity in
another ingredient(s), the concentration of the prohibited material shall not equal or exceed 0.1 percent by weight of
the coating compound. Questions pertinent to this toxic effect shall be referred by the contracting activity to the
qualifying activity. The qualifying activity will act as advisor to the contracting activity. The qualifying activity
will arrange for review of questions by the appropriate departmental medical service.
3.4.5 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.
3.5 Conformance requirements. The paint shall conform to all conformance requirements specified in table III.
3.5.1 Qualification requirements. The paint shall conform to all qualification requirements specified in 3.6 and
3.6 Qualitative requirements. Qualitative requirements shall be as specified in 3.6.1 through 3.6.10:
3.6.1 Brushing properties. When prepared for application as specified in 4.5.1 and tested as specified in 4.5
and 4.5.8, the paint shall be capable of being brushed out and laid off without excess drag on the brush. When dry,
the brushed surface shall be free from sags or runs, and shall show a minimum of brush marks.
3.6.2 Spraying properties. When prepared for application as specified in 4.5.1 and tested as specified in 4.5
and 4.5.9, the paint shall spray satisfactorily in all respects, and shall show no running, sagging, or streaking. The
film shall show no dusting, mottling, or color separation and shall be smooth and uniform.
3.6.3 Flexibility. When prepared as specified in 4.5.1 and tested as specified in 4.5.10, a film of paint shall
withstand bending without visible cracking or flaking.
