4、Change Notice: Replaced “International Truck and Engine Corporation” with “Navistar, Inc.” per corporate directive; changed name of analyzer from Loria to ALSA . 1.0 APPLICATION This specification covers a method for determining surface quality of SMC panels using an Advanced Laser Surface Analyzer

5、(ALSA) . * 2.0 SCOPE This test method describes the procedure used to quantitatively determine the surface waviness of SMC substrates used for Class A exterior applications. The surface quality is evaluated in terms of an ALSA Index Value. 3.0 APPARATUS Required equipment is an Advanced Laser Surfac

7、e carefully controlled. The apparatus must be properly calibrated; the test specimen must be properly aligned between the laser and the reflective screen, and the laser incident angle carefully controlled. 4.1 Test Specimen The test specimen should be of sufficient size to allow a measured area of 2

8、50 x 250 mm (minimum) to be analyzed. The specimen surface must be sufficiently reflective to reflect the laser beam onto a screen, where it is recorded by a camera. A flat surface is preferred, but a curved surface may be used if it is free of styling lines, ribs, bosses or inflected spots in the a

9、rea to be measured. 4.2 Test Specimen Location The specimen or part to be analyzed should be placed approximately halfway between the laser and the screen, so that the first laser measurement line on the test specimen is 1550 mm in front of the reference mark on the laser apparatus. The reference li

10、ne on the front side of the laser should be 1070 mm above the measurement area on the test specimen. The reflective screen is mounted 3 meters in front of the reference mark on the laser apparatus . *ALSA is a registered trademark of Ashland Chemical Co., Composite Polymer Division, P.O.
