High-Pressure Decorative Laminates (HPDL)

We are capable of running the full series of tests prescribed in NEMA LD-3-2005.

The lab has been running these tests since 1982. In addition to testing HPDL to the NEMA LD 3 standard, we have attempted to accommodate requests to test other materials according to the NEMA LD3 test methods, however, results from testing other materials with these procedures may result in values that can be misleading or incompatible with the results from testing HPDL.
