A comparative survey of MS and M2 grade particleboard from two different Canadian manufacturers was conducted to quantify the distinction between grades and the consistency in quality of products marketed as M2 or MS for use as ready-to-assemble (RTA) modular furniture components. A total of 20 full-sized 4-by 8-foot (1.22 by 2.44 m) sheets were intensively sampled for density parameters (ovendry, vertical density profile), internal bond strength, flexural strength and stiffness (modulus of rupture [MOR] and modulus of elasticity [MOE]), and face and edge screw withdrawal resistance (SWR). As expected, the MS grade particleboards were lower in density and strength properties; however, the quality of both grades were greatly dependent on the manufacturer. The M2 grade of panels from one manufacturer were similar to or had lower properties than the MS grade from the other. Both grades of panel from press line A met ANSI A208.1 minimum standards for face SWR, MOR, and MOE, whereas both grades of panels from press line B were borderline or below their respective standards. MS grade panels from both press lines were below ANSI minimum edge SWR of 800 N, which could compromise the suitability of the product for RTA furniture fixed with screws.
