GOST R 54221-2010 PDF

Full title and description

GOST R 54221-2010 — "Гуминовые препараты из бурых и окисленных каменных углей. Методы испытаний" (English: "Humic substances from brown coals, lignites and oxidized coals. Methods of tests"). The standard specifies laboratory test methods for characterizing humic preparations produced from brown and oxidized coals, including determinations of moisture, ash, elemental composition, solubility, humic‑acid yield and selected bioactivity tests.

Abstract

This national standard establishes standardized analytical procedures for evaluating the composition and properties of humic products (commercial humates, growth stimulants, organo‑mineral fertilizers and coal‑alkaline reagents) derived from brown coals, lignites and oxidized coals. It specifies sample preparation, extraction and quantification methods (moisture, ash, C/H/N, alkalinity, water solubility, free humic acids) and gives an example method for estimating biological activity.

General information

• Status: Introduced for the first time; national standard of the Russian Federation (voluntary application; "введен впервые").
• Publication date: Approved 23 December 2010 (Order No. 1020‑ст) and introduced into effect 1 July 2012.
• Publisher: Published/issued in print by Standartinform (2012) and recorded in national standards databases.
• ICS / categories: Fuels and solid fuels (ICS 75.160, specifically solid fuels 75.160.10); related subject area: coals (see ICS grouping for coal-related standards).
• Edition / version: First edition (designated 2010); entered into force 2012.
• Number of pages: Typically published as a short method standard (commonly listed as 14 pages in public catalogues; some distributors list variations such as 14–16 pages depending on layout).

Scope

The standard applies to humic preparations obtained from brown and oxidized coals for research and for commercial products produced by industry (humates/growth stimulants, organo‑mineral fertilizers, coal‑alkaline reagents). Individual test methods in the standard may be applied selectively depending on the intended use of the humic preparation. The prescribed methods enable determination of material composition and key functional properties.

Key topics and requirements

• Sampling and preparation of analytical samples (grinding, air‑drying to constant mass, representative sample sizes).
• Determination of moisture content using specified drying procedures.
• Determination of ash (ash content) by standard ashing methods.
• Elemental analysis: determination of carbon, hydrogen and nitrogen contents (instrumental or classical methods as referenced).
• Determination of alkali (basicity) and soluble fractions (water solubility).
• Extraction and quantification of free humic acids (procedures for extraction, precipitation and gravimetric measurement).
• Example biological‑activity test (seed germination/seedling growth assay illustrated using cucumber seeds) and guidance on calculating activity indicators.
• Reference to normative documents and laboratory equipment/sieves, distilled water and titration reagents required for tests.

Typical use and users

Laboratories performing quality control and analytical testing of humic products; manufacturers of humates and organo‑mineral fertilizers; agricultural research institutes assessing bioactivity of humic preparations; regulatory bodies and standards organizations referencing test methods; R&D groups developing products from brown coal and lignite feedstocks.

Related standards

The standard cites and is used alongside other GOST/sector standards for sampling, reagents and test equipment — for example standards on laboratory sieves, distilled water and sampling of coal (e.g., ГОСТ 10742 series and related laboratory methods), and general solid‑fuel test methods (ash, moisture and elemental determinations). Users typically consult these referenced national methods when implementing the procedures of GOST R 54221‑2010.

FAQ

Q: What is this standard?

A: GOST R 54221‑2010 is a Russian national standard that defines laboratory test methods for humic preparations derived from brown and oxidized coals (humates) to characterize composition and selected properties.

Q: What does it cover?

A: It covers sample preparation, moisture and ash determination, elemental (C/H/N) analysis, alkalinity/solubility measurements, extraction and gravimetric determination of free humic acids, and an example method for assessing biological activity (seed germination/growth). Individual methods can be applied as needed for the product purpose.

Q: Who typically uses it?

A: Quality and analytical laboratories, humate/fertilizer manufacturers, agricultural researchers and R&D groups working with coal‑derived humic products. Regulatory or conformity assessment bodies may reference it when assessing product claims.

Q: Is it current or superseded?

A: The standard was approved by Rosstandart (Order No. 1020‑ст) on 23 December 2010 and introduced 1 July 2012; public registries list it as the issued national standard. For the latest legal or applicability status or any subsequent revisions/amendments, users should check official national standards registers or the issuing authority for updates.

Q: Is it part of a series?

A: It is a single‑topic national method standard focused on humic preparations; it fits within the broader set of Russian standards for solid fuels and fuel testing methods (ICS classes for fuels/solid fuels) and cross‑references other GOST methods for sampling and laboratory apparatus. It is not presented as part of a numbered multipart series.

Q: What are the key keywords?

A: Humic substances, humates, brown coal, lignite, oxidized coal, humic acids, test methods, ash, moisture, elemental analysis, biological activity.
