30、expected, the suitability for the intended purpose and the general characteristics of the species itself. All requirements apply at the time of production, unless the manufacturer states otherwise. EN 14519:2005 (E) 7 5.2 Appearance and finishing 5.2.1 General Grading applies to the face only, unles
