GOST R 55873-2013 PDF

Full title and description

GOST R 55873-2013 — "Уголь активированный. Определение прочности стандартным методом" (English: Activated carbon. Standard test method for hardness). The standard specifies a laboratory method to determine the mechanical strength (resistance to attrition/abrasion) of granular, extruded and crushed (broken) activated carbon.

Abstract

This document describes a standardised procedure for preparing a representative sample of activated carbon, subjecting it to combined vibratory and impact action in a standard test apparatus (metal balls + rotating/vibrating tray), and quantifying strength as mass loss (or percentage of particles broken) after the test. The method includes sample conditioning, required particle-size preselection (removal of fines), test duration and the sieve-based procedure for determining results.

Scope

The standard applies to the determination of hardness (resistance to mechanical attrition/abrasion) of granular (pelletised or lump), extruded (pelleted) and crushed activated carbon intended for technical and industrial uses. For the test, the carbon sample shall contain not less than 90% of particles larger than 180 µm (80 mesh); particle-size distribution shall be determined in accordance with referenced sieving standards. The method is intended for laboratory quality control, specification verification and comparative testing of activated carbon batches.

Key topics and requirements

• Scope and definitions: terms for nominal particle sizes (granular, extruded, broken) and specimen selection rules.
• Sample preparation: drying, sieving to remove fines and to establish the nominal size range for testing.
• Apparatus and materials: standard tray/pan with metallic balls and a mechanical sieving/impact vibrator configured to specified stroke and impact frequency.
• Test procedure: combined vibratory and impact action for a defined time (typical procedure uses a 30-minute exposure), followed by sieving and mass determination of broken material.
• Result calculation and reporting: percent mass loss or retained mass expressed relative to initial mass; conformity criteria and repeatability notes.
• Normative references: related GOSTs for sieving, sample handling and complementary properties (e.g., GOST 16187 and other referenced documents).

Typical use and users

Primary users include manufacturers of activated carbon, quality-control laboratories, purchasers and specifiers of adsorption materials for water and air treatment, chemical process engineers, and regulatory or certification bodies that verify mechanical durability for handling, transport and end-use performance.

Related standards

Standards commonly associated with GOST R 55873-2013 include GOST/R documents and national test-method standards referenced in its normative clause (examples: ГОСТ 16187 for particle-size distribution and other GOSTs cited in the standard's references). The document is often used alongside material specification standards and adsorption-performance test methods for activated carbon.
