TS EN 844-11

TS EN 844-11 is the part of the round and sawn timber terminology series that deals with terms and definitions for degrade caused by insects. Standards of this kind do not describe grading tests or quality limits; they provide a shared technical language so that the same wood defect concepts are used consistently in trade, specification, and European standardization.

What the insect-degrade vocabulary is meant to clarify

In timber technology, insect degrade refers to visible or structural effects associated with insect activity, such as holes, galleries, and other forms of surface or internal damage. The purpose of a terminology document is to define those concepts precisely enough for consistent use in commercial and technical communication. That distinction matters because different defects may look similar in practice, yet they are not interchangeable in documentation, grading language, or product description. This part organizes the vocabulary; it does not itself introduce inspection procedures, numerical acceptance criteria, or performance requirements.

Document context and boundaries

The scope states that the definitions are intended for general commercial use and for terms used in European Standards. TS EN 844-11 is aligned with EN 844-11:1998 and is now withdrawn, so it represents a historical terminology reference rather than an active current edition. Its coverage is intentionally narrow: it focuses on insect-related terms within the broader round and sawn timber vocabulary, not on other timber defects, strength classes, or test methods.

• Shared terminology for round and sawn timber.
• Focused on terms for insect-related degrade.
• Supports consistency in European standard language.
• Intended for general commercial use.
• Not a testing or acceptance standard.
