TS 343

TS 343 is a terminology standard for wood preservation, setting out the terms used in this field and their definitions. Standards of this kind create a common technical language for concepts such as timber, preservative chemicals, treatment processes, and durability-related discussion, helping prevent ambiguity across documents, training, and day-to-day technical communication.

Why terminology matters in wood preservation

Wood preservation is concerned with reducing damage caused by biological attack, moisture, and service conditions by treating wood appropriately and using preservative systems where needed. In practice, the subject spans a number of closely related ideas: treatment methods, preservative agents, exposure conditions, performance expectations, and deterioration mechanisms. A terminology document like TS 343 helps align those concepts by defining them consistently, rather than prescribing how products must perform.

What this standard covers

Based on the stated scope, this standard is limited to terms and definitions for wood preservation. It does not present test methods, numerical limits, or product requirements in the scope information provided. Its value is therefore primarily conceptual and editorial: it supports clear use of technical language in specifications, education, research, and manufacturing contexts where wood protection chemistry and treatment vocabulary need to be used precisely.

• Defines the terminology used in wood preservation.
• Supports consistent use of preservative and treatment-related vocabulary.
• Helps distinguish closely related concepts in technical documentation.
• Focuses on definitions rather than performance requirements or test procedures.
