TAPPI T 410 Standard Test for Weight (Weight Per Unit Area) of Paper and Cardboard

EUROLAB laboratory provides testing and compliance services within the scope of TAPPI T 410 standard. The traditional or commercial term used in the United States to refer to the "weight" per unit area of ​​paper (more precisely, "mass per unit area") has been "base weight", "ball weight" or "substance".

They are defined as the mass, in pounds, of a ball of a given leaf size and number of leaves (usually 500 leaves, sometimes 480 leaves). In many other countries, mass per unit area is expressed in grams per square meter (g/m2).

The French term for mass per unit area, "gramage", is recommended for use in English and French on paper in ISO Committee TC 2 due to its convenience and clear relationship to g/m6. The mass of cardboard per unit area is expressed in pounds per thousand square feet in the conventional system and grams per square meter in the metric system.

SI metric units, in which grams (mass per unit area) are expressed in g/m2, are the preferred units for TAPPI test methods.
