1/
Water, sufficient to bring total volume to 250 mL, shall be
added
2/
This formula should be aged 3 weeks before using, or diluted,
when first prepared, to 1000 mL for use without further dilution.
3/
Triton X-100, ethoxylated primary or secondary alcohols, or
straight-chain alkyl phenols.
3.3.2 Grease removal (applicable to types I, II, and IV). The
diluted conditioner shall be equal or superior to the standard
comparison formula of the same type (specified in table II)
prepared and tested under the same conditions, in removing greasy
films when tested as specified in 4.3.6.
3.3.3 Inhibiting agents. Types I, II, IV and V shall be
noninhibited and free from agents which will tend to interfere
with the free action of the conditioner on the metal being
treated. Type III shall contain an inhibiting agent so that the
attack on the base metal shall be held to a minimum. The
corrosion removal properties of Type III compound shall not be
impaired by the presence of the inhibiting agent. The compound
shall be tested as specified in 4.3.7.
3.3.4 Etching action (applicable to types I, II, IV and V
only). The diluted metal conditioner shall produce no more than
a slight etching action when allowed to remain in contact with
iron, galvanized iron, brass or aluminum at a temperature of 77
9F (25 5C). The etching action shall be essentially equal to
that produced by the standard comparison compound (see table II)
of the same type, when tested as specified in 4.3.8.
