2.4 Order of precedence. Unless otherwise noted herein or in the contract, in the event of a

conflict between the text of this document and the references cited herein, the text of this

document takes precedence. Nothing in this document, however, supersedes applicable laws and

regulations unless a specific exemption has been obtained.

3. REQUIREMENTS

3.1 Qualification. The compounds furnished under this specification shall be products that

are authorized by the qualifying activity for listing on the applicable qualified products list before

contract award (see 4.3 and 6.3).

3.2 Materials. The compounds shall be nonvolatile base materials dispersed in a solvent to

form a fluid formulation conforming to this specification. Aromatic, chlorinated,

chlorofluorocarbon, hydrochlorofluorocarbon solvents, Class I Ozone Depleting Substances

(ODSs), Hexavalent Chromium, Asbestos or Polychlorinated Biphenyls (PCB) shall not be used

in the formulation. The compounds shall be homogeneous, free of lumps, dirt or other suspended

matter, and free of water, chlorides, silicones, and other impurities (see 6.5).

3.2.1 Composition. The composition of the compounds shall be optional with the

manufacturer, but shall be within the limitations specified herein (see 3.2, 3.3, 3.4 and 3.5).

Self-pressurized containers may use the following propellants or may request approval for an

alternative from the qualifying activity.

3.2.1.1 Grade 134a propellant. The propellant for Grade 134a shall consist of

hydrofluorocarbons or a blend containing hydrofluorocarbons. Grade 134a propellant blends

shall contain no chlorinated solvents, hydrochlorofluorocarbons, or fully halogenated

chlorofluorocarbons.

3.2.1.2 Grade CO2 propellant. The propellant for Grade CO2 shall consist of carbon

dioxide. The propellant shall contain no chlorinated solvents, hydrochlorofluorocarbons, or fully

halogenated chlorofluorocarbons.

3.3 Toxicity. The compound shall not adversely affect the health of personnel when used

for its intended purpose. The compound shall not contain known or suspected human
