: Verification values for actual thickness and width at various moisture levels. Full Text Access

The full document contains several critical lookup tables used by manufacturers:

: If the wood's moisture content is higher than the standard nominal moisture level, the actual dimensions must be larger than the nominal ones by the established shrinkage value. gost 67821 75

: Moisture content must be determined in accordance with GOST 16588 .

Because this is a technical legislative document, the full text—including the precise mathematical tables—is best viewed via official PDF repositories: : Rosstandart (Russian) Full Text (PDF) : Meganorm or Stroyinf Annotated Version : Docs.cntd.ru : Verification values for actual thickness and width

: Shrinkage values for thickness and width based on final moisture content.

Below is a summary of the core text and requirements based on official documentation from sources like Rosstandart and Docs.cntd.ru . Because this is a technical legislative document, the

(officially Coniferous sawn timber. Shrinkage value ) is a Soviet-era state standard, still active in many CIS countries, that defines the shrinkage values for softwood lumber to ensure they meet nominal dimensions after drying.
