GOST R 52325-2005 PDF

Full title and description

GOST R 52325-2005 — "Seeds of agricultural plants. Varietal and sowing characteristics. General specifications" (Russian: "Семена сельскохозяйственных растений. Сортовые и посевные качества. Общие технические условия"). The standard establishes unified technical requirements for varietal and sowing qualities of seeds used in agriculture.

Abstract

This national Russian standard defines terminology, classification, quality parameters and basic test/acceptance rules for seeds of major agricultural groups (cereals, legumes, oilseeds, technical and forage/melliferous grasses, and selected specialty crops). It sets requirements for varietal purity, mechanical and biological purity, germination and germinating energy, moisture, and rules for marking, documentation, storage and transfer between seed categories.

General information

• Status: Active (in force / действующий).
• Publication date: Approved 23 March 2005; introduced into force 1 January 2006.
• Publisher: Federal Agency on Technical Regulation and Metrology (Rosstandart) / national standards system of the Russian Federation.
• ICS / categories: OCS/ICS 65.020.20 (seeds and planting material; crop production).
• Edition / version: GOST R 52325-2005 (with published reissues and technical amendments; Amendment No.1 issued by Rosstandart with introduction date 1 January 2026).
• Number of pages: Generally published as 22 pages in many libraries (reissues/retail packages sometimes listed as 24 pages depending on formatting and inclusion of appendices).

Scope

The standard applies to seeds of cereals, grain legumes, oilseeds, technical crops (except sugar beet), forage and melliferous grasses and establishes the general technical conditions for assessing varietal (genetic) purity and sowing (germination) qualities. It covers definitions, requirements for seed categories (reproduction classes), sampling and acceptance, key quality indicators (mechanical purity, varietal impurity, moisture, germination and germinating energy, hard seeds), and references to methods and related normative documents.

Key topics and requirements

• Definitions and classification of varietal and sowing qualities (terminology used for seed quality assessment).
• Requirements for varietal purity and permissible levels of variety admixture by seed category.
• Limits and test requirements for germination, germinating energy, hard seeds and moisture content.
• Mechanical purity, maximum content of inert matter and admixtures, and methods for determining them.
• Sampling, lab testing and documentation/marking rules for seed batches and certificates used in trade and certification.
• References to related GOSTs and normative documents that specify detailed test methods and additional crop-specific requirements.

Typical use and users

Used by seed producers and breeders, seed testing and certification laboratories, agricultural inspection and phytosanitary authorities, grain traders and exporters/importers, agricultural research institutes and agronomists who need to verify or declare seed quality and varietal purity for sowing and trade. It is also used as a baseline for product labeling, certification and shipment documentation in domestic and international seed commerce involving Russian-origin seed lots.

Related standards

The standard cross-references a number of crop- and method-specific GOSTs that define test methods and specific limits. Recent administrative updates replace or update some referenced norms (for example, replacement of certain referenced GOST numbers as noted in Amendment No.1). Other related standards include various GOSTs covering seed testing methods, sampling, seed certification procedures and crop-specific technical conditions (see the standard's normative references for full list).

FAQ

Q: What is this standard?

A: A Russian national standard (GOST R 52325-2005) that sets general technical requirements and acceptance rules for varietal and sowing qualities of seeds of major agricultural crops.

Q: What does it cover?

A: It covers definitions, seed categories, allowable varietal impurities, limits for germination and germinating energy, mechanical and biological purity, moisture limits, sampling and testing procedures, marking and documentation requirements, and references to crop-specific and method standards.

Q: Who typically uses it?

A: Seed producers and breeders, seed-testing laboratories, certification bodies, agricultural regulators and traders who need to verify or document seed quality for sowing and sale.
