Full Description

Purpose.

This test method shall be used to determine the effects of weathering using a xenon-arc lamp source (artificial sunlight) to simulate extreme environmental conditions encountered inside a vehicle due to sunlight, heat, and humidity. This method shall be used to evaluate the colorfastness, as well as being the artificial weathering method to evaluate degradation. This method describes four (4) possible exposure cycles.

• Method A.

Light and Dark Exposure Cycle (100 °C, 420 nm). The cycle alternates between light and dark periods. This cycle is based on ISO 105-B06 exposure condition Number Three (3).

• Method B.

Light Only Exposure Cycle (100 °C, (300 to 400) nm). This cycle is based on ISO 105-B06 exposure condition Number Three (3).

• Method C.

Light Only Exposure Cycle (115 °C, (300 to 400) nm). This cycle is based on ISO 105-B06 exposure condition Number One (1).

• Method D.

Light and Dark Exposure (89 °C, 340 nm). The cycle alternates between light and dark periods. This cycle is based on ISO 105-B06 exposure condition Number Five (5) (SAE J1885/SAE J2412 equivalent with SAE J2413 as the companion document).
