COMPLIANCE

7 FABRICATED and INSTALLED woodwork shall be tested for compliance to these standards

as follows:

7.1 SMOOTHNESS of exposed surfaces:

7.1.1 KCPI (Knife Cuts Per Inch) is determined by holding the surfaced board at an angle to a strong light source

and counting the visible ridges per inch, usually perpendicular to the profile.

Knife Cuts

7.1.2 SANDING is checked for compliance by sanding a sample piece of the same species with the required grit of

abrasive.

7.1.2.1 Observation with a hand lens of the prepared sample and the material in question will offer a

comparison of the scratch marks of the abrasive grit.

7.1.2.2 Reasonable assessment of the performance of the finished product will be weighed against absolute

compliance with the standard.

7.1.2.3 A product is sanded sufficiently smooth when knife cuts are removed and any remaining sanding

marks are or will be concealed by applied finishing coats.

7.1.2.4 Handling marks and/or grain raising due to moisture or humidity in excess of the ranges set forth in

this standard shall not be considered a defect.

7.2 GAPS, FLUSHNESS, and FLATNESS of product and installation:

7.2.1 Maximum gaps between exposed components shall be tested with a feeler gauge at points designed to join

where members contact or touch.
