Certification of the manufacturing process has been in place for many years. NOFMA, The Wood Flooring Manufacturers Association, has been certifying that members' flooring products are correctly manufactured since before 1930. Other associations with written grade rules and standards for the manufacture of wood flooring are MFMA (Maple Flooring Manufacturers Association), CLA (Canadian Lumbermen's Association), and SPIB (Southern Pine Inspection Bureau).
What does certification of manufactured flooring mean? The term "certification" means to vouch for or guarantee that the quality of product meets an established standard. NOFMA vouches for its members' products through quarterly plant inspections by staff inspectors. These inspections attest that the certification standards of manufacture are being met.
Why is certification important? After all, manufacturers who are not NOFMA members say they manufacture to the NOFMA standard. The basis of certification is third party review. Without third party inspection, a manufacturer's claim of meeting the NOFMA, MFMA, or SPIB standard is just that, a claim.
The certified product assures the proper grade, correct moisture content, and correct configuration.
