GOST 23509-79 PDF

Full title and description

GOST 23509-79 — Резина. Метод определения сопротивления истиранию при скольжении по возобновляемой поверхности. National (GOST) test method that specifies procedure, apparatus and reporting for determination of abrasion resistance of vulcanized or thermoplastic rubber when slid against a renewing (replaced) abrasive surface (rotating drum / abrasive sheet method). Often cited as equivalent to ISO 4649 (rubber — determination of abrasion resistance using a rotating cylindrical drum device).

Abstract

This standard defines a laboratory method to measure the abrasion resistance of rubber compounds by sliding a rubber test piece over an abrasive sheet mounted on a rotating drum (renewing/replaceable abrasive surface). The method covers specimen preparation, apparatus requirements, test conditions (load, drum speed, traverse), measurement of mass/volume loss, calculation of relative volume loss and abrasion resistance index, calibration with reference compound and reporting of results. Intended for comparative testing, quality control and specification verification of rubber materials and products.

Scope

Applies to laboratory determination of the resistance of rubber compounds and rubber products to abrasive wear when a rubber specimen slides against a renewing abrasive surface affixed to a rotating drum. The procedure is intended for comparative evaluation, routine quality control, specification checks and research; it does not by itself predict in-service life under all field conditions.

Key topics and requirements

• Definition of test principle: sliding a cylindrical or block rubber specimen over an abrasive sheet mounted on a rotating drum (renewing abrasive surface).
• Apparatus specification: rotating drum dimensions and tolerances, mounting for abrasive sheet, specimen holder (rotating or non-rotating), loading mechanism and speed control.
• Test parameters: normal load, drum rotational speed, lateral traverse, test distance (number of drum revolutions), ambient conditioning and specimen conditioning.
• Specimen preparation: dimensions, conditioning after vulcanization, density determination and procedures for measuring mass loss.
• Calculation methods: conversion of mass loss to volume loss, relative volume loss reporting, and abrasion resistance index relative to a reference compound.
• Calibration and reference materials: use of specified reference compound(s) and abrasive grade; requirements for abrasive replacement/renewal and calibration routines.
• Reporting: required test details, results (volume loss and/or abrasion index), uncertainty notes and any deviations from standard conditions.

Typical use and users

Used by rubber and elastomer manufacturers, product development and R&D laboratories, independent testing houses, quality control departments, tyre and automotive component producers, hose and seal manufacturers, footwear and conveyor belt producers, and standards laboratories that evaluate and compare abrasion performance of rubber compounds and finished parts.

Related standards

Widely aligned with international test methods for rubber abrasion — referenced as equivalent to ISO 4649 (rotating cylindrical drum abrasion test) and later ISO revisions. Users commonly consult related rubber testing standards for specimen preparation, density determination and physical property testing (for example, standards on preparation/conditioning of test pieces and complementary abrasion test methods used in specific industries).

FAQ

Q: What is this standard?

A: GOST 23509-79 is a national (GOST) standard that specifies a laboratory method for determining abrasion resistance of rubber by sliding a test piece over a renewing abrasive surface on a rotating drum (method equivalent in scope to ISO 4649-type drum abrasion tests).

Q: What does it cover?

A: It covers apparatus requirements, specimen preparation and conditioning, detailed test parameters (load, drum speed, traverse), measurement and calculation of mass/volume loss, use of reference compounds, calibration and reporting of results.

Q: Who typically uses it?

A: Rubber manufacturers, testing and certification laboratories, R&D groups, automotive and tyre industry quality teams, producers of hoses, seals, footwear and other rubber products that need abrasion-performance data for development and specification compliance.

Q: Is it current or superseded?

A: The standard text GOST 23509-79 is retained and maintained as a GOST method with noted amendments; it has been used as the national equivalent to international drum-type abrasion standards (ISO 4649 and later revisions). Users should check the current national standards catalogue or standards body for any later replacements, adoptions or national updates before formal use.

Q: Is it part of a series?

A: It is one of a set of national standards for rubber testing and physical property determination; it is often referenced together with standards that define specimen preparation, density measurement and other complementary rubber test methods. It is also associated with the international ISO series on rubber abrasion (ISO 4649 and its revisions).
