TS 4931

TS 4931 is a terminology standard for resin and its natural derivatives from forest sources. Its subject is the naming of resins obtained from coniferous woods or from their cut timber, together with the derivatives derived from them; synthetic resin and synthetic derivatives are excluded. As a vocabulary standard, it helps ensure that the same material is described consistently across forestry, chemistry, processing, and trade contexts.

How the technical vocabulary is organised

In general technical usage, resin refers to a natural exudate or extractive associated especially with coniferous species, and resin-related products may include closely related fractions, processed materials, and derivative substances. Standards of terms and definitions do not usually test materials; they define concepts so that engineers, chemists, and manufacturers use the same words for the same phenomena. That shared language matters when comparing raw materials, discussing processing routes, or classifying products derived from wood sources.

Defined scope and practical value

• The scope is limited to resin and derivatives of natural forest origin.
• Coniferous woods and their cut timber are identified as the source material.
• Synthetic resin and synthetic derivatives are explicitly outside the scope.
• The document is a terminology standard, so its role is definition and naming rather than product testing.
• It supports clearer communication in forest products chemistry and related technical documentation.
