GOST 10852-86 PDF

Full title and description

GOST 10852-86 — "Семена масличные. Правила приемки и методы отбора проб" (Oil seeds — Acceptance rules and sampling methods). The standard specifies rules for acceptance, methods for taking and forming samples of oilseed crops intended for industrial processing.

Abstract

This interstate (GOST) standard defines how consignments of oil seeds (including sunflower, soybean, peanut and other oil-bearing seeds) are to be accepted at delivery and how representative samples are to be taken and prepared for laboratory testing. It covers sampling devices and procedures, sample formation, minimum sample masses and documenting of samples to ensure reliability of quality control and analytical results.

General information

• Status: Active (in force as an interstate standard; restrictions on expiry were removed in later administrative acts).
• Publication date: Introduced 1 July 1987 (designation year 1986 — GOST 10852-86).
• Publisher: Issued as an interstate standard under the State Committee for Standards (Gosstandart) framework — published as a USSR / interstate GOST.
• ICS / categories: ICS 67.200.20 (Oilseeds and pulses; seed sampling and quality).
• Edition / version: GOST 10852-86 (original 1986 designation); later reprints/reissues recorded (reprint June 2010).
• Number of pages: Typically listed as 8 pages in several standards catalogs (some sources list a 10‑page PDF variant).

Scope

The standard applies to oil-bearing seeds harvested and supplied for industrial processing. It sets requirements for acceptance of lots at delivery and establishes methods for selecting primary, incremental and composite samples, formation of laboratory samples and rules for sampling from storage, transport and containers to produce representative test material. It is intended for use where reliable laboratory assessment of seed quality and composition is required.

Key topics and requirements

• Definitions of lot, primary (incremental) sample, combined (composite) sample and laboratory sample.
• Methods for taking samples from stacks, sacks, bulk carriers, railcars and road vehicles, and from processing lines.
• Requirements for sampling devices (manual probes, multi-level samplers, pneumatic/mechanical samplers) and their operation.
• Rules for formation of combined (pooled) samples and preparation of laboratory test portions.
• Minimum masses for combined laboratory samples (commonly applied requirement: combined sample mass not less than 5 kg for many tests), and instructions for splitting and reduction of samples prior to analysis.
• Documentation and marking of samples, chain-of-custody and acceptance decision criteria based on laboratory results.

Typical use and users

Used by grain and oilseed producers, seed merchants, processors (oil mills), inspection and testing laboratories, quality control departments, customs and regulatory bodies, and procurement professionals to ensure representative sampling and fair acceptance of consignments for quality and safety testing.

Related standards

Commonly used alongside other GOST standards for oilseeds and grain quality (for example standards on specific seed quality characteristics, methods of analysis and packing/transport), and later national or regional technical regulations that reference sampling procedures for conformity assessment. Examples of related normative documents include successive GOSTs in the 1085x series that address quality characteristics and testing methods for oil-bearing seeds.

FAQ

Q: What is this standard?

A: An interstate (GOST) standard that prescribes acceptance rules and sampling methods for oil-bearing seeds intended for industrial processing (designation GOST 10852-86).

Q: What does it cover?

A: Procedures for selecting and taking incremental and combined samples from consignments in storage and transport, sample formation and preparation of laboratory test portions, minimum sample masses, sampling devices and documentation required for acceptance and testing.

Q: Who typically uses it?

A: Producers, traders and processors of oil seeds, laboratory analysts, regulatory inspectors and any organization involved in acceptance testing and quality control of oilseed consignments.

Q: Is it current or superseded?

A: The standard is listed as in force (its expiry limitation was removed by later administrative action), though users should check the latest national/regional legal and regulatory framework for any superseding national standards or technical regulations that reference sampling requirements. For official procurement or regulatory use verify current status with the national standards body.

Q: Is it part of a series?

A: Yes — it is one of a set of standards addressing oilseed and seed quality (other related GOSTs in the 1085x–1086x series and separate standards for analytical methods and specific crop requirements).
