3、as authorized the use of this commercial item description for all federal agencies. 1. SCOPE. This commercial item description (CID) covers three types of modified commercial grade talc. Types T1 and T3 are intended for use as stimulants for riot control agents CA (orthochlorobenzylidene malononitri
4、le), CS1 and CS2. Type T1 is also intended for use in dusting and lubrication. Type T4, used for repairing and retreading pneumatic tires on ground vehicles, is equivalent to A-A-52518 Type IV Class B. 2. CLASSIFICATION. The talc shall be of the following types as specified (see 7.3) Type T1 - 35/65
5、 silicon dioxide Type T3 - 55/65 silicon dioxide Type T4 - 53 micrometer (m) 3. SALIENT CHARACTERISTICS 3.1 Chemical and physical characteristics.
