GOST 32594-2013 PDF

Full title and description

GOST 32594-2013 — "Лесоматериалы круглые. Методы измерений" (English: "Round timber. Methods of measurements"). The standard specifies methods for piecewise and group measurement and procedures for determining the volume of round timber (logs) of coniferous and broadleaved species for trade, accounting, customs and production control.

Abstract

GOST 32594-2013 sets out measurement procedures for length, diameter and volume calculation for individual logs and for stacks (group methods). It includes measurement tolerance rules, tables and formulas for volume calculation, and normative guidance on measuring instruments (recommended metrological characteristics). The standard aligns with EN 1309-2:2006 (NEQ) and is intended to harmonize timber measurement practice used in commerce and inventory.

General information

• Status: Active (in force) — established as an interstate (GOST) standard; scheduled to be replaced by a 2025 revision (see FAQ).
• Publication date: Registered/approved December 30, 2013; date of introduction into effect: 1 January 2015.
• Publisher: Adopted/put into effect by the Federal Agency for Technical Regulation and Metrology (Rosstandart) as a межгосударственный стандарт (interstate GOST).
• ICS / categories: 79.040 (Technology of timber processing; logs, sawlogs and sawn timber).
• Edition / version: GOST 32594-2013 (original issue 2013; entry-into-force 2015).
• Number of pages: Typically published with 38–40 pages depending on publisher format (common commercial copies list 38 pages).

Scope

The standard applies to round timber (logs) of coniferous and broadleaved species. It establishes both individual (piece) and group (stack) measurement methods and procedures to determine log volume for trade, state and internal accounting, customs control and other applications where standardized timber measurement is required. Methods are selectable based on required accuracy and practical measurement technology.

Key topics and requirements

• Definitions and terminology for round timber measurement (length, diameter, curvature, end-trimming, etc.).
• Procedures for measuring log length and diameter (including curved logs) and rules for rounding and reporting results.
• Piecewise methods: formulas and tables to calculate volume of individual logs.
• Group (stack) methods: rules for sampling, average-diameter techniques and stack-volume estimation.
• Metrological requirements and recommended measuring instruments (Appendix A): tape measures, calipers, automatic log scanners, and their permissible errors.
• Reference to EN 1309-2:2006 (NEQ) and normative cross-references to other GOSTs used for instruments and wood defect definitions.

Typical use and users

Used by forestry enterprises, timber traders, sawmills, customs and inspection authorities, inventory and accounting departments, surveying teams and laboratories involved in timber measurement and trade. The standard is applied where consistent, legally or commercially accepted timber volume determination is required.

Related standards

Normative references and related documents commonly cited include EN 1309-2:2006 (timber measurement - NEQ), and several GOSTs covering measuring instruments and wood defect terminology (examples: GOST 7502, GOST 427, GOST 9462). National measurement and metrology regulations that implement GOSTs are also relevant.

FAQ

Q: What is this standard?

A: GOST 32594-2013 is an interstate (GOST) standard titled "Лесоматериалы круглые. Методы измерений" (Round timber. Methods of measurements). It prescribes standardised procedures for measuring logs and calculating their volume.

Q: What does it cover?

A: It covers terminology, measurement of length and diameter (including curved logs), piece and group methods for determining log volume, rounding and reporting rules, calculation tables/formulas and metrological requirements for measuring instruments.

Q: Who typically uses it?

A: Forestry companies, timber traders and processors, customs and inspection services, inventory/accounting teams, surveyors and laboratories involved in timber trade and official accounting.

Q: Is it current or superseded?

A: As of February 27, 2026, GOST 32594-2013 remains in force. However, a revised standard — GOST 32594-2025 — was approved in 2025 and is scheduled to enter into force on 1 July 2026, at which point it will replace GOST 32594-2013. Users planning long-term implementations should track the 2025 revision and its effective date.

Q: Is it part of a series?

A: The document is part of timber-processing and measurement standards (ICS 79.040) and cross-references several other GOSTs and international norms (notably EN 1309-2:2006). It should be used together with related metrology and wood-quality standards applicable in the supply chain.

Q: What are the key keywords?

A: Round timber, logs, measurement, volume, piece measurement, stack measurement, diameter, length, metrology, EN 1309-2.
