Our laboratory is familiar and experienced with the ANSI/HPVA EF 2020 standard and many of its testing procedures. These include  Bond Line/ Three-Cycle Soak Test (4.2), Determination of Moisture Content (4.3),  and Flooring Characteristics Evaluation (4.4). The Flooring Characteristics Evaluation includes analysis of width tolerance, overwood, crook, end alignment (squareness), flatness, and uniformity of thickness. 

The larger picture above shows two samples that underwent Bond Line/ Three Cycle Soak Testing and passed. They had no visible delamination or physical alteration after the allotted time period. 

The cover of the standard was obtained from the Decorative Hardwoods Association website.

Our laboratory is familiar and experienced with the NALFA LF 01-2019, ISO 4586, NEMA LD3, and ASTM D1037 standards. The testing procedures that we conduct include:

• Resistance to Surface Wear/Wear Resistance: ISO (11), NEMA (3.13), NALFA (3.7)

• Resistance to Impact by Large Diameter Ball/Ball Impact Resistance/Large Ball Impact Resistance: ISO (25), NEMA (3.8), NALFA (3.5)

• ​Resistance to Crazing: ISO (28)

• Resistance to Scratching/Scratch Resistance: ISO (29), NEMA (3.7)

• Resistance to Staining/Chemical Resistance/Cleanability: ISO (31), NEMA (3.4), NALFA (3.4), KCMA (9.4)

• Lightfastness/Light Resistance: ISO (33), NEMA (3.3), NALFA (3.3)

• Resistance to Blistering/Radiant Heat Resistance: ISO (40), NEMA (3.10)

• Resistance to Wet Heat/Boiling Water Resistance: ISO (41), NEMA (3.5)

• Determination of Microscratch Resistance: ISO (42)

• Dart Impact Resistance/Small Ball Impact Resistance: NEMA (3.9), NALFA (3.6)

• Static Bending: ASTM D1037 (9)

• Tension Perpendicular to Surface (Internal Bond): ASTM D1037 (11)

• Hardness: ASTM D1037 (17)

The ANSI/HPVA HP-1-2016 is a comprehensive standard with several analytical and testing procedures that our laboratory performs. The analytical tests include dimensions and tolerances (3.13) such as squareness (3.13.1) and straightness (3.13.2). The testing procedures include dry shear testing (4.3), cyclic-boil shear testing (4.4), two-cycle boil testing (4.5), three-cycle soak testing (4.6), and moisture content determination (4.7).

The larger picture above shows a plywood product in a dry shear testing (4.3) apparatus performed in our mechanical testing laboratory. This sample was cut to test the interior bond line of the seven-ply board.
