Physical & Mechanical Properties
The CPA’s Physical and Mechanical Properties (PMP) Grademark Program provides independent, accredited certification for wood panel products. By monitoring plant quality controls, regular product testing, and CPA inspections, the program ensures panels consistently meet the performance and manufacturing requirements specified by ANSI standards, building codes, and federal regulations.
These standards include:
- ANSI A208.1 Particleboard (PB)
- ANSI A208.2 Medium Density Fiberboard (MDF) for Interior Applications
- ANSI A135.4 American National Standard, Basic Hardboard
- ANSI A135.5 American National Standard, Prefinished Hardboard Paneling
- ANSI A135.6 American National Standard, Engineered Wood Siding (EWS)
- ANSI A135.7 American National Standard, Engineered Wood Trim (EWT)
