SCOPE The material defined by these specifications is a high or low wear interior trim appliqu. 2. APPLICATION These specificat
3、ions were released originally for appliques used on instrument panels and interior door trim panels. A low wear application is a part that will not be in contact by the customer on a continual basis, such as the area behind the steering column or in a vertical area on the instrument panel that is no
4、t located near control adjustments . A high wear application is a part that is in contact continually, such as the door panel, console, the radio or any other control adjustments. 3. REQUIREMENTS In addition to the requirements listed, parts which are heat bonded shall also meet all applicable requi
