    The precision of the granite flat plate is referenced to various advanced national standards, and the flatness tolerance is based: JB\/T7975-1999 standard: 000 grade = 1 \u00d7 (1 \u00a0\u00a0d\/1000) um;00 grade = 2 \u00d7 (1 \u00a0\u00a0d\/1000) um; 0 grade = 4 \u00d7 (1 \u00a0\u00a0d\/1000); 1 grade = 8 \u00d7 (1 \u00a0\u00a0d\/1000) um (d is the diagonal mm) (measurement temperature is generally 20 \u00b1 \u00a0\u2103).<\/p>\n
