Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 1190-2009 "Technical Requirements for Tires for Construction Machinery". Compared with GB/T 1190-2009,
The main technical changes outside the reform are as follows.
--- Increased normative references GB/T 30193 (see Chapter 2);
--- Increased the provision that the surface of the radial tires is not allowed to expose the cord (see 4.1.2);
--- Explained the physical strength requirements of tires that are not suitable for steel cord adhesive strength indicators (see Table 1);
--- Increased requirements regarding tire durability (see 4.3);
--- The test method has added the provisions of the durability test method (see 5.5);
--- Removed the regulations on measuring the rim in the tire mark (see 6.1 of the.2009 edition);
--- Added the requirement that tires implanted with radio frequency identification (RFID) tags should have permanent electronic tag marking (see 6.1.3);
--- Added the rule that radial tires should be engraved with "RADIAL" (see 6.1.4).
This standard was proposed by the China Petroleum and Chemical Industry Federation.
This standard is under the jurisdiction of the National Tire and Rim Standardization Technical Committee (SAC/TC19).

3 terms and definitions
The terms and definitions defined in GB/T 6326 and GB/T 2980 apply to this document.
4 Requirements
4.1 Basic requirements
4.1.1 The specification, size, air pressure and load of the tire, the type of use of the tire, and the classification code of the pattern should conform to GB/T 2980 or related technologies
Documentation requirements.
4.1.2 Various tires are not allowed to have defects that seriously affect the service life, such as delamination between components, sponge-like, traveller breakage and severe
Defects such as pumping, broken and split multiple cords, pleated cords in the tires, and cords with rubber edges in the tire crown.
Exposed. If a pad is used, the pad is not allowed to be defective in appearance and cracked.
4.1.3 Other appearance quality requirements of tires and pads shall meet the requirements of HG/T 2177.
4.1.4 If inner tubes and pads are used, they shall meet the requirements for matching with outer tubes.
4.2 Physical properties of tires
The physical properties of the tire shall meet the requirements in Table 1.
Table 1 Physical properties of tires
4.3 Tire durability
After the tire has undergone the durability test, the tire air pressure should not be lower than the specified initial air pressure; after the test, the appearance inspection should not be performed (tread,
Sidewall, ply, airtight layer, belt or buffer layer, bead, etc.) delamination, ply crack, cord peeling, cord break, chipping, joint crack
Opening, cracking, and abnormal deformation of the tire.
