Relationships among the thickness change, mass loss, density, and mean board strength (internal bond strength (IB), nail-head pull-through strength (NHPT), and lateral nail resistance (LNR)) of phenol–formaldehyde resin-bonded particleboard (PB) subjected to outdoor exposure. Low-temperature site: site 1. Middle-temperature site: site 2. High-temperature sites: sites 3 and 4. The site no. is described in Table 1. r correlation coefficient. Triple asterisk statistical significance at 0.1 % level
