Escopo e aplicabilidade

This standard applies to the calculation and assessment of energy consumption for enterprises producing architecture ceramics, sanitary ceramics, and wear-resistant alumina balls. It is also applicable for energy consumption control in new, reconstructed, and expanded production projects. Manufacturers in these sectors must comply with these mandatory limits to operate in China. It references product standards like GB/T 4100 and GB/T 6952.

Requisitos técnicos

The standard establishes a tiered system for energy consumption limits, categorized into three grades where Grade 1 represents the lowest energy consumption. It defines specific limit requirements for various product categories, including dry-pressed ceramic tiles, ceramic boards, extruded ceramic tiles, dry-hung hollow ceramic boards, sanitary ceramics, and alumina grinding balls. For existing facilities, the standard sets a mandatory energy consumption limit corresponding to the Grade 3 requirements. Existing manufacturers must ensure their unit product energy consumption does not exceed these baseline thresholds. For new, reconstructed, or expanded facilities, stricter energy consumption access values are enforced, aligning with the Grade 2 requirements. This ensures that new production lines adopt more energy-efficient technologies from the outset. Additionally, the standard introduces a thickness correction coefficient for dry-pressed ceramic tiles and ceramic boards. This factor adjusts the energy consumption limits based on the product's thickness, providing a more accurate assessment for thicker products. The calculation methods are aligned with GB/T 2589-2020.

Métodos de ensaio

The standard outlines the statistical scope and calculation methods for comprehensive energy consumption. It requires enterprises to measure and statistically analyze energy consumption during the reporting period, including coal, oil, gas, purchased heat, and electricity. Energy metering equipment must comply with GB/T 24851. The comprehensive energy consumption is calculated by converting various energy sources into standard coal equivalents using specified formulas and calorific value conversion factors.

Perguntas frequentes

What products are regulated under GB 21252-2023?

It regulates architecture ceramics (including dry-pressed tiles, ceramic boards, and extruded tiles), sanitary ceramics, and wear-resistant alumina balls.

What are the main updates in GB 21252-2023 compared to previous versions?

The 2023 version merges and replaces GB 21252-2013 and GB 30181-2013. It introduces a three-tier energy consumption limit system, adds requirements for ceramic boards and dry-hung hollow ceramic boards, and includes a thickness correction coefficient for specific products.

What is the difference between requirements for existing and new facilities?

Existing facilities must meet the Grade 3 energy consumption limits, while new, reconstructed, or expanded facilities must meet the stricter Grade 2 limits.
