I've spend a lot of time measuring LAB on approximately 300 paperqualities. You would be amazed at how many whites were incompatible with the 12647 standard.
Wood free paper usually refers to papers that are made from plants other than trees - e.g. hemp, banana, cane, straw, cotton, etc. Woodfree also refers to paper which is made from chemical pulp where the 'woody' lignins in the timber were destroyed in a chemical reaction. If not removed, the lignins cause paper to yellow and become brittle with age. In that case - wood free does not mean tree free.
