GMW14162 - Revision / Edition: 2 Chg: Date: 06/00/11 COLORFASTNESS TO ARTIFICIAL WEATHERING
Note: In the event of conflict between the English and domestic language, the English language shall take precedence.
Purpose. This test method shall be used to determine the effects of weathering using a xenonarc 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 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.
Method B. Light Only Exposure Cycle (100 °C, 300 to 400 nm). This cycle is based on ISO 105-B06 exposure condition Number Three.
Method C. Light Only Exposure Cycle (115 °C, 300 to 400 nm). This cycle is based on ISO 105-B06 exposure condition Number One.
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 (SAE J1885/SAE J2412 equivalent with SAE J2413 as the companion document).
Foreword. This test method was developed by the Global Textile Team to create a common method for evaluating colorfastness to artificial weathering.
Applicability. Not applicable.
