3、Note: In the event of conflict between the Korean and English language, the Korean language shall take precedence. 1.1 Purpose. The purpose of this standard is to determine the abrasion resistance of the automotive trim components if the physical friction has been applied to them. 1.2 Applicability.

4、 This standard shall be used to determine the abrasion resistance of plastic parts to which functional finishes (e.g. foiling, embossing, paint, metalized parts etc) have been applied. 2 References Note: Only the latest approved standards are applicable unless otherwise specified. 2.1 External Stand
