1.1 Form:
This specification covers liquid wipe solvent cleaners.
1.2 Application:
These wipe solvents have been typically used for cleaning aircraft primary and secondary
structural surfaces prior to application of adhesion promoters, sealing materials, primer
materials, and topcoat materials over primed surfaces. However, usage is not limited to such
applications.
1.3 Classification:
Solvents covered by this specification are classified as follows (see 8.4):
Type 1 – Cleaning prior to primer or topcoat materials.
Type 2 – Cleaning prior to sealing compounds.
Form 1 – Hydrocarbon-based. Wipe solvents composed of a mixture of photochemically
reactive hydrocarbons and/or oxygenated hydrocarbons and/or exempt solvents.
Form 2 - Aqueous. Wipe solvents in which water content is 80% or more by volume of the wipe
solvent solution as applied.
Class 1 – Most environmentally preferable (low vapor pressure and/or low HAP/VOC).
Containing de minimis HAP (Hazardous Air Pollutants) and VOC (Volatile Organic
Compound) defined as concentrations less than 0.1 percent by weight for carcinogens and
1.0 percent for non-carcinogens, or as defined by the following: for Form 1 - maximum vapor
pressure of 7 mm Hg at 68 °F (20 °C) and no HAPs; for Form 2 - flash point greater than
200 °F (93 °C) and the solution must be miscible with water. Class 1 is exempt from
housekeeping measures as defined by the Environmental Protection Agency (see 8.4).
Class 2 – Moderately environmentally preferable (moderate vapor pressure). Maximum vapor
pressure of 45mm Hg at 68 °F (20 °C).
1.3 (Continued):
Class 3 – Least environmentally preferable (HAPs and/or high vapor pressure). Vapor pressure
greater than 45mm Hg at 68 °F (20 °C).
1.4 Safety:
Hazardous Materials: While the materials, methods, applications and processes described or
referenced in this specification may involve the use of hazardous materials, this specification
does not address the hazards which may be involved in such use. It is the sole responsibility of
the user to insure familiarity with the safe and proper use of any hazardous materials and to
take necessary precautionary measures to ensure the health and safety of all personnel
involved.strRefField
