ISO 13608:2014 PDF

Overview

ISO 13608:2014 - Plywood - Decorative veneered plywood - specifies terms, classifications, requirements, test methods and marking for decorative veneered plywood where the surface veneer thickness is less than 0.55 mm. The standard covers panels with natural wood veneer, coloured veneer, laminated veneer, multilaminar veneer and other decorative surfaces bonded to a plywood core.

Key phrases: ISO 13608:2014, decorative veneered plywood, veneer thickness <0.55 mm, plywood veneer standards.

Key technical topics and requirements

• Scope and terminology: Defines “decorative veneered plywood” and related veneer types (natural, coloured, laminated, multilaminar) using ISO vocabulary references.
• Classifications:
  • By decorative veneer type (natural, coloured, laminated, multilaminar).
  • By face: single-faced or double-faced.
  • By exposure class: Class 1 (dry conditions) and Class 2 (tropical-dry/humid conditions).
• Panel dimensions and tolerances: Dimension and squareness tests reference ISO 1954 and ISO 9426. Thickness tolerances vary by nominal thickness (e.g., tighter tolerances for thinner panels and defined within‑panel variation).
• Surface appearance and quality grades: Visual inspection and classification by appearance (referencing ISO 2426 series). Colour-difference arbitration using photoelectric colour measurement: indiscernible (<1.5 ΔE), inconspicuous (~1.5–3.0 ΔE), obvious (>3.0 ΔE).
• Physical and chemical requirements (Table highlights):
  • Moisture content: 6.0–14.0% (ISO 16979).
  • Immersion and delamination: total delamination length between surface veneer and core **
