3.2.3 Composition. The paint shall consist of the ingredients listed
in table I footnotes in the proportions shown in table I, except that the
amount of carbon black may be varied as necessary to meet color requirements.
In addition, to assist in meeting drying times, brushing, condition in
container, and storage stability requirements, driers, antisettling,
antisagging, and antiskinning agents may be varied as necessary to meet the
other requirements of the specification are met.
3.2.4 Safety. 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 identified by
Occupational Safety and Health Administration (OSHA) as regulated carcinogens,
or International Agency for Research on Cancer (IARC) latest monographs, or
the latest annual report of the National Toxicology Program (NTP); and shall
have no extremely hazardous substances (EHS) or toxic chemicals identified in
40 CFR 355 and 372, respectively. The enamel shall not contain more than 5
percent cobalt compounds and 5 percent manganese compounds by weight in its
formulation. 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 or 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 enamel. The enamel shall have no adverse effect on
the health of personnel when used for its intended purpose (see 6.7).
3.3 Quantitative requirements. The enamel shall conform to the
