Organization: SAE
Publication Date: 1 April 2012
Status: active
Page Count: 11
scope:

This test method specifies the exposure rack(s), black box(es), and instrumentation, which shall be used for the outdoor weathering of materials for automotive exterior application.

All dimensions are nominal unless otherwise noted.

A list of approved exposure test sites is generally available from specified automotive manufacturers.

Sample preparation, exposure duration, and performance evaluation procedures not presented in this method are covered in material specifications of the different automotive manufacturers.

This method includes three procedures:

PROCEDURE A - Exposure in a rack without backing; or, as required, (1) expanded metal backing, or (2) backed plywood at a fixed angle of 5 degrees from the horizontal facing the equator.

PROCEDURE B - Exposure in an unheated black box at a fixed angle of 5 degrees from the horizontal facing the equator. For non-rigid specimens, see note below.

PROCEDURE C - Exposure at angles other than 5 degrees as specified in PROCEDURE A AND PROCEDURE B.

Special Tests - These are established on an as-needed basis to duplicate end-use conditions. Examples are in-service position of large assemblies or components that cannot be accommodated in a 5 degrees exposure rack.

NOTE - If required for nonrigid specimens, use expanded metal backing for unbacked exposures. Expose specimens in a rack with plywood backing 13 mm to 19 mm (1/2 in to 3/4 in) that have an end-use application in a backed configuration.
