Para la misma especificaci\u00f3n: (\\boldsymbol{Grado 000 < Grado 00 < Grado 0})
Cuadrados peque\u00f1os (por ejemplo, 200 \u00d7 200 mm):
Grado 000: \u22641,5 \u03bcm
Grado 00: \u22642,5 \u03bcm
Grado 0: \u22644,0 \u03bcm
Cuadrados medianos (p. ej., 400 \u00d7 400 mm):
Grado 000: \u22643,0 \u03bcm
Grado 00: \u22645,0 \u03bcm
Grado 0: \u22648,0 \u03bcm<\/li>\n\n\n\n
Del mismo modo, se aplica la regla de que, cuanto mayor es el grado, menor es la tolerancia, lo que constituye la base para garantizar una medici\u00f3n precisa.
200 \u00d7 200 mm:
Grado 000: \u22641,0 \u03bcm
Grado 00: \u22641,8 \u03bcm
Grado 0: \u22643,0 \u03bcm<\/li>\n\n\n\n

Segmentos de dimensi\u00f3n
La norma divide los cuadrados en segmentos de distintas dimensiones en funci\u00f3n de la longitud del lado exterior (200, 250, 300, 400, 500, 630 mm, etc.). Cuanto mayor es la dimensi\u00f3n, mayor es la tolerancia permitida.
Evaluaci\u00f3n comparativa internacional
Grado 000 nacional \u2248 Grado AA internacional; Grado 00 \u2248 Grado A; Grado 0 \u2248 Grado B.
Diferenciaci\u00f3n en el uso
El grado 000 es obligatorio para la trazabilidad metrol\u00f3gica; el grado 00 se utiliza para el mecanizado de precisi\u00f3n y el control de calidad en laboratorio; el grado 0 puede utilizarse directamente para el control de calidad en la producci\u00f3n in situ.<\/p>\n\n\n\n![\"\"](\"https:\/\/jtlcnc.com\/wp-content\/uploads\/2026\/01\/\u65b9\u5c3a4.jpg\")
