ISO 12625-6 Basis weight

Standard:

ISO

Method:

ISO 12625-6

Title:

Determination of grammage

Scope

ISO 12625-6 Basis weight specifies a test method for the determination of grammage of tissue paper and tissue products. Grammage may be measured by determining the mass of a test piece or test pieces of tissue paper or tissue products cut to specified dimensions, or by determining the mass and area of a specified number of units of finished tissue products.

Principle

The mass and area of a test piece or test pieces of either a tissue paper or a tissue product is measured and the grammage is calculated as the mass per unit area of the test pieces taken. For finished paper products, the grammage may also be calculated from the mass and area of a specified number of the finished tissue product items.
