適用範囲

This standard applies to the energy consumption calculation, evaluation, and assessment for the production of all-steel radial tyres, semi-steel radial tyres, off-the-road (OTR) tyres, bias tyres, and carbon black for the rubber industry. It is mandatory for existing facilities and new, reconstruction, or expansion projects. It replaces the previous versions GB 29449-2012 and GB 29440-2012.

技術要求

The standard establishes a three-tier energy consumption limit grading system for unit products, where Tier 1 represents the lowest energy consumption. It categorizes limits for different types of tyres and carbon black separately. For existing facilities producing tyres or carbon black, the energy consumption must meet the Tier 3 requirements. Existing manufacturers must strictly adhere to these baseline limits to maintain operational compliance. For new, reconstructed, or expanded projects, the energy consumption access value must meet the more stringent Tier 2 requirements. This ensures that new industrial capacities adopt more energy-efficient technologies. The standard also details specific statistical boundaries, including energy consumed in main production, auxiliary production, and affiliated production systems, while excluding energy used for infrastructure and technical transformations.

試験方法

The standard outlines calculation methods rather than physical testing methods. It specifies formulas for calculating the comprehensive energy consumption of tyres and carbon black. For carbon black, the production mass must be converted to an N330 equivalent mass using specific conversion factors. Energy values for various fuels and energy-consuming working fluids should be converted to standard coal equivalents, referencing the coefficients provided in the appendices or measured according to standards like GB/T 213 and GB/T 384.

よくある質問

What products are regulated under GB 29449-2024?

It regulates the energy consumption of all-steel radial tyres, semi-steel radial tyres, OTR tyres, bias tyres, and carbon black used in the rubber industry.

What are the main changes in GB 29449-2024 compared to previous versions?

The new version integrates GB 29449-2012 and GB 29440-2012, introduces a three-tier energy consumption limit grading system, and removes the advanced energy consumption values and energy management sections.

What are the compliance requirements for new tyre manufacturing projects?

New, reconstructed, or expanded projects must meet the Tier 2 energy consumption limits. Existing facilities are required to meet the Tier 3 limits.
