Overview

EN 636:2012+A1:2015 - Plywood: Specifications (CEN) defines the European requirements for plywood used in both general purpose (non‑structural) and structural applications across dry, humid and exterior conditions. The standard sets product requirements, classification rules and verification procedures for plywood (including overlaid and coated plywood), and is referenced by EN 13986 for construction applications.

Key topics and requirements

  • Scope and use classes: Covers plywood for Service Class 1 (dry), Service Class 2 (humid/protected external) and Service Class 3 (exterior/exposed) as defined in the standard and related documents.
  • Classification by bending properties: Provides a system to classify plywood by bending strength (F‑classes) and modulus of elasticity (E‑classes). This classification can be cross‑referenced with EN 12369‑2 to derive characteristic values for design.
  • Product vs. characteristic values: Values given in Clause 4 are product properties only - not characteristic values for structural design. Characteristic design values are obtained from EN 12369‑2 or manufacturer testing per EN 789/EN 1058/ENV 1156.
  • Bonding quality and formaldehyde: Specifies bonding performance requirements (referencing EN 314) and formaldehyde release classification and test conditioning (EN 717 series).
  • Dimensional tolerances and physical tests: Refers to standard methods for thickness, length/width, squareness and moisture/density testing (EN 324, EN 315, EN 322, EN 323).
  • Biological durability: Addresses suitability for different exposure conditions and notes that enhancement treatments (preservatives) are not covered; for guidance see CEN/TS 1099 and EN 335‑3 use classes.
  • Verification & marking: Defines factory production control, external control and documentation/marking rules for boards marketed in the EEA.

Practical applications and users

Who uses EN 636:2012+A1:2015:

  • Plywood manufacturers - to certify product compliance and label boards correctly.
  • Architects and structural engineers - to select suitable plywood classes and cross‑reference characteristic design values (via EN 12369‑2).
  • Specifiers and procurement teams - to write requirements for construction and non‑structural projects.
  • Test laboratories and conformity assessors - for sampling, testing and factory production control.
  • Regulators and certification bodies - for harmonized evaluation in construction products (EN 13986).

Practical benefits:

  • Ensures consistent mechanical performance, bonding quality, and suitability for environmental exposure.
  • Simplifies selection by providing classification by bending properties and clear verification procedures.

Related standards

Relevant cross‑references include EN 12369‑2 (characteristic values for plywood), EN 314 (bonding quality), EN 310 (bending tests), EN 717 (formaldehyde), EN 13986 (construction applications) and CEN/TS 1099 (biological durability guidance).

Die Norm EN 636:2012+A1:2015 legt klare und präzise Anforderungen für Sperrholz fest, das sowohl für allgemeine Anwendungen als auch für strukturelle Anwendungen in trockenen, feuchten oder Außenbedingungen geeignet ist. Dies zeigt die Vielseitigkeit und Relevanz dieser Norm in verschiedenen Bereichen der Bau- und Möbelindustrie. Insbesondere der Klassifizierungsansatz, der auf den Biegeeigenschaften basiert, bietet eine wertvolle Grundlage für die Bewertung und Auswahl geeigneter Sperrholzprodukte. Die Norm ist besonders stark, da sie nicht nur allgemeine Anforderungen formuliert, sondern auch spezifische Hinweise zur Eignung von Sperrholz in unterschiedlichen Klimabedingungen und Anwendungen gibt. Sie berücksichtigt sowohl standardisierte als auch besondere Produkteigenschaften und bezieht sich auf die erforderliche Dokumentation in Bezug auf Anwendungsakzeptanz, was die Transparenz in der Produktverwendung fördert. Ein weiterer wichtiger Aspekt der Norm ist die klare Abgrenzung zwischen den Produktwerten und den charakteristischen Werten, die für Berechnungen in der technischen Praxis verwendet werden. Diese Differenzierung hilft den Anwendern, Missverständnisse zu vermeiden und sicherzustellen, dass die richtigen Werte in den Entwurfsprozess einfließen. In Bezug auf biologische Haltbarkeit weist die Norm darauf hin, dass zusätzliche Leitlinien in CEN/TS 1099 zu Rate gezogen werden sollten. Dies unterstreicht die Bedeutung des Normungsprozesses, sich an technische Entwicklungen und branchenspezifische Anforderungen anzupassen, während gleichzeitig die grundlegenden Anforderungen für Sperrholz gewahrt bleiben. Die EN 636:2012+A1:2015 ist somit eine essenzielle Norm im Bereich der Holzwerkstoffe, die für Fachleute in der Bau- und Möbelindustrie von großer Bedeutung ist, um qualitativ hochwertige und zuverlässige Produkte zu gewährleisten.

표준 EN 636:2012+A1:2015는 합판에 대한 요구 사항을 규정하는 유럽 표준으로, 일반용 및 구조용 응용 모두에 적합합니다. 이 표준은 건축 응용을 위해 EN 13986에서 참조되며, 건축 자재로서의 합판의 강도 및 적합성을 보장하는 데 중요한 역할을 합니다. 이 표준의 강점 중 하나는 합판의 분류 시스템을 제공하여 휨 성능에 기반한 다양한 유형의 합판을 명확히 구분할 수 있다는 점입니다. 이는 사용자가 특정 용도에 가장 적합한 합판을 선택할 수 있도록 돕고, 구조적 안정성을 확보하는 데 기여합니다. 또한, EN 636 표준은 일반용 및 구조용 응용에서의 다양한 환경 조건(건조, 습기, 외부)에서도 적용 가능하여 그 범위가 넓다는 장점이 있습니다. 그러나 이 표준은 오버레이 또는 코팅에 사용되는 재료나 공정, 생물적 내구성 향상과 관련된 재료나 공정을 다루지는 않으므로 사용자는 이러한 측면에 대한 추가 지침이 필요할 수 있습니다. 이를 위해서는 CEN/TS 1099를 참조하여 생물적 내구성과 보존 처리 필요성에 대한 정보를 얻을 수 있습니다. EN 636 표준에서 제공하는 값들은 제품 특성과 관련이 있으며, 특정 디자인 계산에 사용되기 위한 '특성 값'은 아닙니다. 설계 계산에 필요한 특성 값은 EN 12369-2에서 제공되거나 제조회사가 EN 789, EN 1058 및 ENV 1156에 따른 시험 결과를 바탕으로 제공합니다. 이러한 명확한 지침은 사용자에게 신뢰할 수 있는 정보를 제공하여 합판의 선택과 사용에 있어 더 나은 결정을 할 수 있도록 돕습니다. 결론적으로, EN 636:2012+A1:2015는 합판의 다양한 적용 분야에서 중요한 표준으로, 그 강점과 포괄적인 범위는 건축 및 구조물 설계 및 구현에 있어서 필수적인 요소로 자리잡고 있습니다.
