Overview

ISO 1096:2021 is an international standard developed by ISO that defines a comprehensive system for the classification of plywood panels. This fourth edition provides updated guidelines for categorizing plywood based on general appearance and principal performance characteristics. It serves as a definitive reference for manufacturers, suppliers, and users, ensuring consistency and quality in plywood products worldwide.

The standard emphasizes key classification criteria such as panel type, shape, surface appearance, finishes, mechanical properties, exposure conditions, and specific treatments-allowing for precision in selection and application of plywood materials.

Key Topics

• Panel Types: Classification includes veneer plywood, wood core plywood (blockboard, battenboard, laminboard), and composite plywood as defined by ISO 2074.

• Form and Shape: Panels are categorized as flat or moulded, providing clarity for design and manufacturing specifications.

• Surface Appearance: Standards ISO 2426-1 through ISO 2426-4 specify plywood classifications by surface appearance across general, hardwood, softwood, and palm plywood varieties.

• Surface Finishes: Includes unsanded, sanded (single or double side), touch-sanded, scraped, overlaid (with resins, plastics, metals, or decorative paper), pre-finished, textured, and veneered plywood finishes.

• Mechanical Properties: Differentiates plywood for non-structural applications (e.g., furniture, wall paneling) and structural uses (e.g., floor decking, wall sheathing, concrete forming).

• Exposure Conditions: Classification based on environmental use such as dry, tropical dry/humid, and high humidity/exterior conditions as per ISO 12465.

• Specific Treatments: Details treatments to improve biological durability (against fungi and insects), moisture resistance, and fire reaction, enhancing plywood performance and longevity.

Applications

ISO 1096:2021 provides practical value by enabling professionals to:

• Select Suitable Plywood: Based on clear visual and performance classifications tailored to various construction, furniture, and industrial needs.

• Ensure Quality and Compliance: Manufacturers can standardize plywood products to meet expected international benchmarks, facilitating trade and customer confidence.

• Design and Engineering: Architects and engineers can specify the correct panel types and finishes aligned with structural and environmental requirements.

• Optimize Durability: Understanding exposure classifications helps in choosing plywood panels treated for enhanced moisture and pest resistance, crucial for outdoor and high-humidity environments.

• Facilitate Global Trade: Uniform classification supports international commerce by reducing misunderstandings and ensuring consistency in plywood specifications.

Related Standards

ISO 1096:2021 references several related ISO standards that complement the classification system:

• ISO 2074: Defines plywood vocabulary, panel types, forms, and surface finishes in detail.

• ISO 2426 (Parts 1 to 4): Provides detailed classification of plywood by surface appearance for general, hardwood, softwood, and palm plywood respectively.

• ISO 12465: Covers plywood specifications related to exposure conditions including moisture and environmental durability.

Together, these standards establish a robust framework for plywood classification that addresses both appearance and functional properties.

---

ISO 1096:2021 plays a critical role in harmonizing plywood classification globally. By facilitating clear communication and quality assurance, it supports industries ranging from construction and furniture manufacturing to transportation and packaging, enhancing material selection for durable and aesthetic plywood products.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
