ISO 18776:2008/Amd 1:2013

Overview

ISO 18776:2008/Amd 1:2013 is an important amendment to the international standard ISO 18776:2008, detailing specifications for Laminated Veneer Lumber (LVL). This amendment, issued by ISO in 2013, primarily updates the bonding quality assessment requirements for LVL products. Laminated Veneer Lumber is a high-performance engineered wood product used in construction and manufacturing, valued for its strength, dimensional stability, and sustainability.

The amendment replaces earlier normative references related to bonding quality tests with more specific and relevant standards, ISO 10033-1 and ISO 10033-2, enhancing the accuracy and consistency of bonding quality evaluation. This ensures that LVL products meet stringent performance criteria critical for safety and durability in their end-use applications.

Key Topics

• Standard Revision: ISO 18776:2008/Amd 1:2013 updates the original ISO 18776:2008 standard.
• Bonding Quality References: Replaces references from ISO 12466-1 and ISO 12466-2 (plywood bonding) with ISO 10033-1 and ISO 10033-2, which are specific to LVL bonding quality test methods and requirements.
• Testing Methods: Mandates that LVL bonding quality be assessed strictly according to the newly referenced ISO 10033 series.
• Document Scope: Focuses on technical specification amendments without changing dimensional or structural LVL requirements.
• Technical Committee: Developed under ISO/TC 89 (Wood-based panels), Subcommittee SC 3 (Plywood).

Applications

ISO 18776:2008/Amd 1:2013 is vital for manufacturers, quality inspectors, and construction professionals involved with Laminated Veneer Lumber products. Applications include:

• Construction Industry: Use of LVL as structural components such as beams, joists, headers, and framing materials requires adherence to bonding standards to ensure safety and performance.
• Manufacturing: LVL-based products must meet bonding criteria for reliability and durability in furniture, paneling, and engineered wood products.
• Quality Assurance: Testing and certification labs employ the updated bonding test methods to verify compliance and maintain product quality.
• Sustainability and Compliance: Ensures LVL meets international standards, supporting global trade and regulatory requirements.

Related Standards

For a comprehensive understanding of laminated veneer lumber specifications and testing, consider these related ISO standards:

• ISO 18776:2008 - Base standard for LVL specifications before amendment.
• ISO 10033-1 - Test methods for bonding quality of LVL, providing detailed procedures.
• ISO 10033-2 - Performance requirements and criteria for bonding quality in LVL.
• ISO 12466 series - Previous bonding quality standards for plywood, superseded for LVL testing.
• ISO/IEC Directives, Part 1 and Part 2 - Governing rules for developing and maintaining international standards, ensuring consistency and quality.

By adhering to ISO 18776:2008/Amd 1:2013, stakeholders in the LVL supply chain improve material reliability and compliance, fostering safer construction practices and enhanced product longevity worldwide.
