Scope:

The stiffness of paper and paperboard is measured by determining the bending moment, in millinewton-centimeters, required to deflect the free end of a clamped specimen 38.1 mm wide, through a maximum of 15° from the centre line of the clamp. The force is applied to the lower end of the specimen at a distance of 50.8 mm from the edge of the clamp. The range of force measured is approximately 100 to 49,000 mNcm.

Some instruments have been equipped with ultra-sensitive attachments to test lightweight papers that give results below 1.0 test unit on the 0 to 10-test range. Samples shall be cut 38.1 mm x 38.1 mm to fit this attachment. Measurements made using the low range attachments may not agree with measurements using the full range instrument when used on the same specimen. The use of this ultra-sensitive attachment is not considered to be included in this standard.
