General Information
Overview
SIST EN 635-1:1996, established by CEN, defines the general rules for classifying plywood by its surface appearance. This European standard is essential for manufacturers, suppliers, and quality inspectors involved in plywood production and trade. It provides a consistent framework for assessing plywood qualities based on visual surface characteristics, ensuring transparency and reliability across the supply chain. Notably, this part of the standard excludes overlaid plywood, focusing solely on the natural surface appearance of plywood sheets.
Key Topics
- Surface Appearance Classification: SIST EN 635-1:1996 sets out the criteria for evaluating the visible quality of plywood surfaces, including characteristics like knots, veneer defects, and other visual marks.
- General Rules and Terminology: The standard includes definitions and explanatory principles to unify the understanding of surface classification terms and procedures.
- Scope Limitation: It explicitly excludes overlaid plywood such as those covered with laminates or treated with synthetic films, which are covered under separate standards.
- Quality Grades: While part 1 provides the framework, subsequent parts of EN 635 specify different quality grades based on surface defects and allowable imperfections.
- Harmonized Language: The standard is published in multiple languages, enabling internationally consistent application across European markets.
Applications
SIST EN 635-1:1996 is widely used in:
- Manufacturing Quality Control: Ensuring plywood products meet agreed surface appearance standards before delivery.
- Procurement Specifications: Buyers and contractors specify surface classification requirements to meet aesthetic or functional project needs.
- Trade and Compliance: Facilitating common understanding in commercial transactions by standardizing visual evaluation.
- Design and Architecture: Enabling architects and designers to select plywood surfaces suitable for visible applications where appearance matters.
- Educational Use: Training materials for quality inspectors and manufacturing personnel often reference this standard to build foundational knowledge.
