Determination of the Fogging Characteristics of Interior Automotive Materials
1.1 This recommended practice describes two methods for determining the tendency of interior
materials used in automobiles and other vehicles to (a) produce a light scattering deposit (fog) on a
glass surface, or (b) produce a measurable deposit (mass) on aluminum foil.
1.2 This document is applicable to the measurement of a fog condensate on glass or aluminum foil
surfaces within the limits of the test conditions.
1.3 It is the responsibility of the user of this document to establish appropriate safety and health
practices and to determine the applicability of regulatory limitations prior to its use.
Rationale: This document has been edited for the following reasons: to eliminate redundancy, to commonize
terminology, to consolidate methodology, eliminate specimen weighing in the gravimetric procedure, and
to eliminate references to specific equipment suppliers per SAE policy.
