Gfl GMq538P =Ib - I 900b379 0007673 077 m I Materials and Processes - Procedures I GENERAL MOTORS ENGINEERING STANDARDS WEATHERING EXPOSURE TESTS FOR INTERIOR TRIMS GM9538P conducting natural weathering exposure tests to evaluate the exposure tolerance of interior automotive materials, compo- nents and assemblies. The tests are commonly conducted in climatic regions which offer extreme weathering environments, such as Arizona and Florida. Material and/or Performance Specifications will identify the region. When using this specification, one 1.1 CLASSIFICATION. or more of the following suffixes must be used after the speci- fication number to identify the exposure fixture, i.e., GM9538P U/G-SSTL-XXX, where XXX is defined in 3.1.2.1.1. SUffiX U/G-SSTL-XXX Description Under Glass - Static Sealed fixture Temperature Limited to a maximum of XXX degrees (3.1.2.1 through 3.1.2.1.3) Under Glass - Tracking Sealed fixture Temperature Limited to a maximum of XXX degrees (3.1.2.4) Under Glass - Static Sealed fixture Temperature Limited with a Water tray for added humidity to a maximum of XXX degrees (3.1.2.3) Under Glass - Tracking Sealed fixture Temperature Limited with a Water tray for added humidity to a maximum of XXX degrees (3.1.2.4) Special test which requires some nonstandard test condition(s) may be used as additional suffix to above test futture designations (3.1.2.5) 1 SCOPE. This specification describes procedures for in MJ/m2 with artificial light exposure energies (measured over a very narrow wavelength range) and usually expressed in kJ/ m2. 1.3.4 Seasonally Adjusted Solar Radiation (SASR): Total solar radiation measured under test fixture glazing and adjusted both to relate the various limit temperature fixtures to a common reference temperature and to account for the differ- ence in time spent at the fixture limiting temperature during the various seasons. This allows testing throughout the entire year with comparable results. 1.3.5 L*a*b* Color System: A color measurement system using orthogonal coordinates to describe color. The L* axis is the white-black (light-dark) axis: Large L*-light, Small L*= dark. The a* axis is the red-green axis: +a*-red, -a*=green. The b* axis is the yellow-blue axis: +b*=yellow, -b*=blue. 1.3.6 Delta E (AE): A resultant color change calculated by the equation: AE = (AL*2+Aa*2 + Ab*2)*n 1.3.7 L*C*h” Color System: A color measurement system that converts the L*a*b* rectangular values to L*C*h” cylin- drical polar coordinates. The L* is the same as in the L*a*b* system. The C* vector is the saturation value, distance from the L* (lightness) axis, in the a*b* plane: Large C*=pure color (vivid), Small C*-pastel (pale). C* is calculated by the equa- tion: The h’ value is the rotational distance in the a*b* plane and determines the hue. An h” of 0” = Red, 90” = Yellow, 180” = Green and 270” = Blue. The h’ is calculated by the equation: h”=arctan (b*/a*) 1.3.8 Delta H* (AH*): The computed hue difference between two points in the L*C*h” color space, calculated by the equa- tion: AHe = (AE*2-AL*2-AC*2)“2 1.3.9 Specular Gloss: The ratio, expressed as a percent, of the quantity of light reflected from a surface to the quantity inci- dent on the surface in the specular (mirror reflected) direction. 1.3.10 Degradation definitions and rating scale are shown in Appendix A. U/G-TSTL-XXX U/G-SSTLW-XXX U/G-TSTLW-XXX Special 1.2 APPLICABILITY. Any passenger car, truck, multipur- pose vehicle or bus interior material, component or assembly that has the potential for deterioration in appearance or func- tion when exposed to natural weathering. 1.3 DEFINITIONS. 1.3.1 Total solar radiation: Natural light less than 3000 nm in wavelength. 1.3.2 Ultraviolet (UV) radiation: Natural light less than 400 nm in wavelength. 1.3.3 Langley: A traditional unit of measure for natural light energy defined as 1 gcal/cm2 . A Langley is equivalent to .04184 MJ/m2. NOTE: The Langley is restricted by definition to the expres- sion of natural light energy. The MJ/m2 is a more universally recognized unit of energy measurement. However, for the pur- poses of this specification, it is not appropriate to compare natural light exposure energies (measured over the total solar or the UV radiation wavelength ranges) and usually expressed 2 REFERENCED STANDARDS.
