GOST 19242-73 PDF

Full title and description

GOST 19242-73 — "Угли бурые, каменные и антрацит. Классификация по размеру кусков" / "Brown coals, hard coals and anthracite. Size classification". The standard defines the nominal size classes (grade names and fraction limits) used for sorting, marking and trade of lump coals and anthracite.

Abstract

GOST 19242-73 specifies classification names (for example: плитный, крупный, орех, мелкий, семечко, штыб, рядовой and combined fractions) and the numerical limits of particle-size classes used in handling, sale and technical use of brown coal, bituminous coal and anthracite. It is a short, prescriptive standard used to harmonize size terminology, grading sieve limits and conventional fraction codes across mining, transport and industrial consumers.

General information

• Status: Withdrawn / no longer in force in the Russian Federation (marked as "утративший силу" in Russian registries); historically a USSR interstate standard. Users should check national registries for current, replacement documents before applying.
• Publication date: Approved by the State Committee for Standards (Gosstandart) on 29 October 1973; date of entry into force 1 January 1975.
• Publisher: State Committee for Standards of the Council of Ministers of the USSR (Gosstandart); developed by the Ministry of Coal Industry of the USSR.
• ICS / categories: OKSTU 0301 (local classification); broadly falls under ICS 73.040 (Coals).
• Edition / version: Original designation GOST 19242-73 (1973). Amendment No. 1 approved 17 March 1989 and entered into force 1 January 1990 (text commonly published with Amendment No.1 integrated).
• Number of pages: Short document — published versions commonly listed as approx. 3–8 pages depending on publisher / integrated amendments (many commercial providers show a 3-page PDF extract).

Scope

Applies to brown coals, hard (bituminous) coals and anthracite and establishes the names, conventional codes and size limits of particle-size classes used for sorting, shipment, inventory and technical specification of lump and combined coal fractions. The standard is intended for producers, traders, transporters and industrial consumers who require consistent size designations for handling, combustion, processing and quality control.

Key topics and requirements

• Definition of standard size-classes (example names: плитный (plita), крупный (krupny), орех (orekh), мелкий (melkiy), семечко (semechko), штыб (shtyb), рядовой (ryadovoy)) and conventional combined classes for mixed fractions.
• Numerical sieve limits (lower and upper size bounds) assigned to each class (values expressed in mm; amendment introduces additional or simplified class limits such as 13–100 mm and simplified sorts 25–200/300 mm).
• Conventional short codes / marks used on shipping documents and commercial specifications for class identification.
• Guidance for combined fractions and "oversize/undersize" groupings used in industrial and simplified sortings.
• Reference to interaction with other coal standards (the size classes are referenced by other technical standards for coal products and fuels).

Typical use and users

Primary users include coal miners, preparation plants, bulk coal traders, freight/port handlers, power generation and cement industries, and laboratory/quality-control personnel who need an agreed vocabulary and numeric limits for separating and reporting coal fractions. It is used in commercial contracts, shipping marks, inventory classification and process feed specifications.

Related standards

GOST 19242-73 originally replaced earlier GOSTs (for example GOST 5287-50 and GOST 5634-51) and is referenced by later fuel and coal technical standards. Users commonly consult related standards governing coal quality parameters, sampling and testing (for example standards on rank/classification, calorific value, ash and sulfur limits and methods). Because GOST 19242-73 has been withdrawn in some jurisdictions, check contemporary national GOST R / regional standards and recent technical regulations for current normative references.

FAQ

Q: What is this standard?

A: GOST 19242-73 is an interstate (USSR) standard titled "Brown coals, hard coals and anthracite. Size classification" that defines conventional names, codes and numerical size limits for coal fractions used in handling and trade.

Q: What does it cover?

A: It covers the classification by piece size (fraction limits and names) of brown coal, bituminous coal and anthracite, including combined and simplified fraction groupings used for shipment and processing.

Q: Who typically uses it?

A: Coal producers, preparation plants, commodity traders, freight handlers, power plants, cement and brick manufacturers, and laboratory personnel for consistent grading, specification and documentation of coal consignments.

Q: Is it current or superseded?

A: In Russian registries GOST 19242-73 is marked as having lost force (утративший силу) — it is no longer current in the Russian Federation; historically it remains a widely cited sizing/classification reference and was amended (Amendment No.1, approved 1989, effective 1990). Before application, check the current national/regional standards or regulatory documents for the applicable replacement or updated sizing rules.

Q: Is it part of a series?

A: It is one of a set of coal-related GOSTs covering classification, sampling and test methods; it replaced earlier GOSTs on size classification and is cross-referenced by later technical standards dealing with coal quality and use. Users should consult the suite of coal standards for complementary test methods and quality requirements.

Q: What are the key keywords?

A: Coal size classification, fraction, lump coal, anthracite, brown coal, GOST, grading, merchantable coal fractions.
