3. REQUIREMENTS

3.1 First article. When specified (see 6.2), a sample shall be subjected to first article

inspection in accordance with 4.2.

3.2 Materials. Unless otherwise specified herein, the materials used shall be in

accordance with the manufacturer's material specifications. The compound shall consist of a

nonvolatile base material dispersed in a petroleum solvent. The compound shall be homogeneous,

fluid, and shall meet the requirements of this specification. The compound shall have no

detrimental effect on materials of construction or the performance of motor vehicles or trailers

when used as intended (see 4.6.1 and 6.4).

3.2.1 Safety. The compound shall not contain any substance of a highly toxic nature.

The compound shall have no adverse effect on the health of personnel when applied properly and

used for its intended purpose (see 4.6.1).

3.2.1.1 Aromatic hydrocarbons. The compound shall not contain any benzene

hydrocarbons (see 4.6.1).

3.2.1.2 Halogenated hydrocarbons. The compound shall not contain any halogenated

hydrocarbons (see 4.6.1 and 4.6.4).

3.3 Chemical and physical characteristics.

3.3.1 Nonvolatile content.

3.3.1.1 Type I. The percentage by weight of the nonvolatile content to meet the

performance requirements of 3.4, shall be established during testing. The nonvolatile content of

any succeeding lot shall be within � 5 percent (5%) of the established value (see 4.6.5).

3.3.1.2 Type II. The nonvolatile content, expressed as a percentage by weight, shall be

established during testing except that the nonvolatile content shall be not less than 52% based on

the compound as received as being 100%. The nonvolatile content of any succeeding lot shall be

within � 5% of the established value (see 4.6.5).
