5. ASSESSING INSPECTION RESULTS
We accept or reject an order on the basis of Acceptance Quality Levels (AQL) 0.65, 1.0 and 2.5 for Class A, B and C defects.
|AQL' s for Class A, B and C defects
||moisture content, straightness of right angles and parallel sides, width, joining of locking system, deformation
According to the SSPNI:
For a 20' container with 3,000 m2 of laminate flooring, the sample size would be 80 m2. The container would be rejected if within the 80 m2 inspected there were more than 1.5 m2 of class A defects, more than 4.0 m2 of class B defects or more than 5.5 m2 of class C defects.
For example, for a 20' container with 3,000 m2 of laminate flooring, the sample size would be 80 m2.
