Hardwood General Grading


NOFMA SPECIFICATIONS


Flooring shall be Tongued and Grooved and End Matched (unless otherwise indicated). Flooring shall not be considered of standard grade unless the lumber from which the flooring is manufactured has been properly kiln dried. The NOFMA standard is that flooring is manufactured at a 6% - 9% Moisture Content with a 5% allowance for pieces outside that range up to 12% Moisture Content, and to fit a “GO, NO-GO” NOFMA flooring gauge.

 

  1. NOFMA members are required to mark all bundles of standard grade flooring with the grade and color (or species if applicable).
  2. Plank Flooring designated by a grade name listed in this Grading Rule Book must conform to that grade description.
  3. Members may manufacture Plank Flooring under other grade names and descriptions which are registered with the NOFMA office to qualify for Complaint Inspection Services.

  8. Nested bundles shorter than 8' nominal length are designated “shorter packaging”.
