Foreword
This Standard is corresponding to ASTM D 5603.2001 “Standard Classification for
Rubber Compounding Materials - Recycled Vulcanized Particulate Rubber”. The
consistent degree is not equivalent.
The main differences between ASTM D 5603.2001 and this Standard are as follows.
— ADD the terms and definitions;
— The ground vulcanized rubber is divided into three categories according to the
category and special purpose of rubber products.
1) Ground vulcanized rubber of whole tire, which is divided into 2 series
according to the structure. radial tire and diagonal tire;
2) Non-tire ground vulcanized rubber, which is divided into 4 series according to
the texture. butyl rubbers, nitrile rubber, ethylene propylene diene monomer
rubber, and polyurethane rubber;
3) Ground vulcanized rubber of road modified asphalt, which is divided into 2
series according to the application. all-steel radial tire and other tires.
— ADD the requirements for the content of harmful substances and the
determination methods of harmful substances;
— DELETE the mechanical screening method for residues on sieve in the original
edition;
— ADD the determination of tensile strength and elongation at break;
— DELETE “vulcanization flat band method” in the density determination items.
This Standard replaces GB/T 19208-2003 “Ground vulcanized rubber”.
Compared with GB/T 19208-2003, the main changes of this Standard are as follows.
— ADD the safety statement;
— ADJUST the normative references (see Chapter 2);
— ADD the terms and definitions (Annex A of this edition);
— RE-CLASSIFY ground vulcanized rubbers (Table 1 of this edition);
— MODIFY and add some technical indexes and requirements (Table 2 and Table
3 of this edition);
— ADD the requirements for the content of harmful substances and the
determination methods of harmful substances (5.4 and 6.1.5 of this edition);
— CHANGE the inspection item of “moisture mass fraction” to “heating loss” (see
6.1.1);
— MODIFY the determination method of residues on sieve; DELETE the
mechanical screening method in the determination of residues on sieve (6.2.1 of
this edition);
— ADD the calculation equations of acetone extracts, residues on sieve, ferric
content, and fiber content (6.1.3, 6.2.1.3, 6.2.2, and 6.2.3 of this edition);
— CHANGE “determination of injection density” to “determination of volume
density” and specify the determination methods (6.2.4 of this edition);
— ADD the plasticating conditions of natural rubbers; CHANGE the roller
temperature of “40 ± 5°C” to “(50 ± 5)°C” (Table 6 of this edition);
— MODIFY the vulcanizing time of samples (6.2.6.1 of this edition);
— MODIFY the inspection rules (Chapter 7 of this edition).
The Annex A of this Standard is normative.

Warning — Anyone who uses this Standard shall have working experience in
professional laboratory. This Standard does not cover all the possible safety
problems. Users have responsibilities to take suitable safety and health
measures, which shall be ensured that they are conform to the conditions
specified in the relevant national laws and regulations.
1 Scope
This Standard specifies the classification, technical requirements, test methods,
inspection rules, packaging, marks, storage, and transportation requirements of
ground vulcanized rubbers that are extracted from various recycled vulcanized
rubbers.
This Standard is applicable to the ground vulcanized rubbers of different particle
diameters which are made from various vulcanized rubbers according to the process
conforming to the national economic recycling requirements.
