GB/T 1190-2018Technical specification of earth-mover tyres (English PDF)

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). This standard was drafted.

1 Scope

GB/T 1190-2018 is the Chinese national standard on technical specification of earth-mover tyres, in the field of rubber and plastic industries. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 28 December 2018 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 November 2019. Classification: ICS 83.160.99, CCS G41. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the terms and definitions, requirements, test methods, marking and packaging, use and maintenance of construction machinery tires. This standard applies to new construction machinery pneumatic tires (including tires, inner tubes and cushion belts).

3 Terms and definitions

The terms and definitions defined in GB/T 6326 and GB/T 2980 apply to this document.

5 Test method

5.1 The tensile strength and elongation at break of the tire tread rubber are sampled according to GB/T 519, and type 2 cutters are used according to GB/T 528. experimenting.

5.2 Abrasion of tire tread rubber is sampled according to GB/T 519 and tested in accordance with GB/T 1689.

5.3 The adhesion strength between the various components of the tire is sampled according to the provisions of GB/T 519, and tested according to the provisions of GB/T 532.

5.4 The hardness of the tire tread rubber is sampled in accordance with GB/T 519 and tested in accordance with GB/T 531.1.

5.5 The tire durability can be tested in accordance with GB/T 30193.

5.6 The tensile strength, elongation at break and permanent deformation at break of the belt shall be sampled in accordance with GB/T 519 and used in accordance with GB/T 528. The test specimens cut by a profile cutter are tested.
