Plywood

Details

Plywood Tests

Evaluate surface appearance of plywood or “the nature and limits of characteristics inherent in wood and manufacturing defects enabling the visual assessment of the plywood for allocation to an appearance class” as specified in PNS/ISO 2426-2:2021

Measure the thickness, determine moisture content and density of Class III ((High Humidity/Exterior Conditions) or Type I (Exterior/Marine); Class I (Dry conditions) or Type II (Interior/Ordinary) plywood and blockboard; and Class II (Tropical dry and Humid conditions) or substandard Type I. 

Evaluate bond quality thru wet shear test and percent wood failure for Classes I to III and Type I plywood.  Determine bending strength of Classes I to III and conduct 3-cycle delamination for Type II plywood and blockboard.

Performed using several equipment such as the digital micrometer for thickness; laboratory oven and digital weighing balance for moisture content; boiling vat, laboratory oven, plywood testing machine (shear and bending), and magnifying lens for the bond test of Classes I-III and Type I plywood; three-cycle delamination oven and dipping vat for the bond test of Type II plywood.

Based on PNS/ISO 12465:2017 as required by the DTI-Bureau of Product Standards.

Adhesives, Sealants and Coatings

Adhesive Tests

  •  Analyze the properties of adhesives such as viscosity, total solids, pH, flammability and volatile matter.
  • Characterize the main components of adhesives using Fourier Transform Infra-red (FTIR).
  • Analyze thermal properties of adhesives using Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA).
  • Also determine the formaldehyde emission of wood and related products. Exporters of wood furniture and furnishings must abide by the importing countries’ strict policy regarding the F-emission limits on wood and similar products.
