Full title and description

ISO 10983:2014 — Timber — Finger joints — Minimum production requirements and testing methods. Specifies minimum requirements for the manufacture and testing of bonded finger joints used in structural wood products such as glued laminated timber (glulam), cross-laminated timber (CLT) and finger‑jointed timber.

Abstract

ISO 10983:2014 sets out minimum production requirements and test methods for bonded finger joints in structural timber products. It applies principally to joints produced in coniferous (softwood) species and, where data allow, to selected broadleaf (hardwood) species. The standard excludes impressed (die‑formed) joints and — for laminated products — applies to individual laminations; large finger joints in glulam are not covered.

Scope

Defines minimum production requirements and associated testing methods for bonded finger joints used in structural timber elements (e.g., glulam laminations, CLT laminations and finger‑jointed timber). The scope covers typical bonding and testing considerations needed to ensure bond integrity and adequate mechanical performance for structural use, while explicitly excluding die‑formed (impressed) joints and very large finger joints in certain glulam applications.

Key topics and requirements

• Minimum production requirements for bonded finger‑joint manufacture (surface preparation, adhesive application, pressing/curing as applicable).
• Testing methods to verify bond quality and mechanical performance of finger joints (procedures and acceptance criteria for production and laboratory testing).
• Applicability guidance for species: primarily coniferous (softwoods); selected broadleaf (hardwoods) where bonding data are available.
• Exclusions and limitations — does not apply to impressed/die‑formed joints; applies to individual laminations in laminated products and excludes very large finger joints in glulam construction.
• Interface with product quality control and production inspection practices used by timber manufacturers and testing laboratories.

Typical use and users

This standard is used by timber product manufacturers (finger‑joint and glulam/CLT producers), product quality and process engineers, testing and certification laboratories, structural engineers specifying timber components, and conformity assessment bodies. It supports factory production control, product development, type testing and routine laboratory verification of bonded finger joints.

Related standards

Related documents and regional standards often used alongside ISO 10983 include earlier ISO 10983:1999 (previous edition) and European standards addressing glued laminated timber and glue‑line testing such as EN 14080 (requirements for glued laminated timber) and standards that specify delamination and glue‑line tests (EN 391 and related test methods). These documents are commonly referenced when specifying production and delamination test protocols for structural glued timber products.

FAQ

Q: What is this standard?

A: ISO 10983:2014 is an international standard that specifies minimum production requirements and testing methods for bonded finger joints used in structural timber products.

Q: What does it cover?

A: It covers manufacture and test methods for bonded finger joints in structural timber laminations (glulam, CLT laminations, finger‑jointed timber), including applicability to softwoods and, where data exist, some hardwoods. It excludes die‑formed finger joints and large finger joints in certain glulam products.

Q: Who typically uses it?

A: Timber manufacturers, production and quality engineers, testing laboratories, structural engineers and certification/conformity bodies use this standard to specify, control and verify bonded finger joint production and performance.

Q: Is it current or superseded?

A: The 2014 edition (Edition 2) is the current published version; it was reviewed and confirmed during ISO’s periodic review cycle (confirmation noted in 2019 and again in 2025).

Q: Is it part of a series?

A: ISO 10983 is a stand‑alone standard focused on finger joints but sits within a broader family of timber standards (timber structures, glulam, glue‑line testing) and is commonly referenced alongside regional standards such as EN 14080 and delamination test standards (e.g., EN 391) when specifying production and testing regimes.

Q: What are the key keywords?

A: Finger joint, bonded joint, glued laminated timber, glulam, cross‑laminated timber, production requirements, testing methods, glue‑line, delamination, structural timber, ISO 10983.
