Foreword
This document was drafted in accordance with the provisions of GB/T 1.1-2020
“Directives for standardization - Part 1.Rules for the structure and drafting of
standardizing documents”.
This document replaces GB 29449-2012 “The norm of energy consumption for per unit
product of tyre” and GB 29440-2012 “The norm of energy consumption per unit product
for carbon black”. Compared with GB 29449-2012 and GB 29440-2012, in addition to
structural adjustments and editorial changes, the main technical changes are as follows.
a) DELETE some terms and definitions (see 3.1 ~ 3.7 of GB 29449-2012 and 3.1
and 3.2 of GB 29440);
b) ADD level of allowance value of energy consumption (see Clause 4 of this
document);
c) DELETE advanced values of energy consumption (see 4.3 of GB 29449-2012 and
GB 29440-2012);
d) MODIFY “Statistical scope” (see 6.1 of this document, 5.1 of GB 29449-2012
and GB 29440-2012);
e) DELETE “Energy-saving management and measures” (see Clause 6 of GB
29449-2012 and GB 29440-2012).
Attention is drawn to the possibility that some of the elements of this document may be
the subject of patent rights. The issuing authority of this document shall not be held

Norm of energy consumption per unit production of tyre and
carbon black
1 Scope
This document specifies the level of allowance value of energy consumption per unit
production (abbreviated as energy consumption), technical requirements, statistical
scope of tyre and carbon black, and describes the calculation methods.
This document applies to the energy consumption calculation, evaluation and
assessment of existing all-steel radial tyres, semi-steel radial tyres, earth-mover tyres
and diagonal tyres and carbon black production for the rubber industry, as well as
energy consumption control for new, rebuilt and expanded projects.

6.1.1 Energy consumption per unit production of tyre
6.1.1.1 The statistical scope of comprehensive energy consumption of tyre production
includes the primary and secondary energy actually consumed by the main production
system, auxiliary production system and subsidiary production system of tyre
production enterprises from the entry of raw materials into the factory boundary to the
delivery of tyre products, but does not include various energy consumed by the
construction of projects such as infrastructure and technical transformation.
6.1.1.2 The energy consumed by the main production system includes various energy
consumed in the entire production process from raw materials, semi-finished products,
finished products, inspection to packaging and delivery.
6.1.1.3 The energy consumed by the auxiliary production system includes the various
energy consumed by the auxiliary facilities such as heating, power supply, water supply,
gas supply, heating and ventilation, storage, fire protection, safety, environmental
protection, logistics, etc. configured for the main production system.
6.1.1.4 The energy consumed by the subsidiary production system includes the various
energy consumed by the production command system specially configured for the
production system and the office buildings, laboratories, operation rooms, lounges and
other facilities within the factory boundary that serve the production.
6.1.1.5 The recycled waste heat and waste energy for internal use shall no longer be
included in the energy consumption. If it is exported to the outside, it shall be deducted
from the total energy consumption according to the actual external supply.
6.1.1.6 The tyre output is the mass of qualified tyre products that meet the requirements
of GB 9743, GB 9744 and GB/T 1190 during the statistical reporting period. The mass
of tyre products of various specifications is calculated in tons according to the actual
measured mass.
6.1.1.7 The calorific value of solid fuel shall be measured in accordance with the
requirements of GB/T 213 and GB/T 30727, the calorific value of liquid fuel shall be
measured in accordance with the requirements of GB/T 384, and the calorific value of
gas fuel shall be measured in accordance with the requirements of GB/T 12206.
6.1.1.8 When primary energy such as coal, natural gas, and biomass is used as input
energy, it shall be calculated according to the measured calorific value. If there is no
measured calorific value, the calculation of coal equivalent conversion coefficient is
shown in Annex B; the calculation of coal equivalent conversion coefficient of
purchased heat and electricity is shown in Annex B; the calculation of coal equivalent
conversion coefficient of air, nitrogen, and water is shown in Annex C.
6.1.1.9 The calculation of coal equivalent conversion coefficient of gasoline, diesel,
liquefied petroleum gas, acetylene, and calcium carbide consumed in the auxiliary
production system is shown in Annex B and Annex C.
6.1.1.10 Tyre product production enterprises shall be equipped with energy metering
instruments in accordance with the requirements of GB 17167 and GB/T 21367.
6.1.1.11 When a tyre production enterprise has a carbon black production line, the tyre
production unit is used as the dividing boundary; all input vapor and electricity are
included in the comprehensive energy consumption of tyre production.
6.1.2 Energy consumption per unit production of carbon black
6.1.2.1 The statistical scope of comprehensive energy consumption of carbon black
includes various energy consumed in the complete production process of carbon black
production enterprise from the storage of fuel and raw materials (including pretreatment)
to the delivery of carbon black finished products, including various energy actually
consumed by reaction, quenching, collection, granulation (drying), refining, packaging,
and wastewater, waste gas, waste residue recovery and dust recovery, but does not
include various energy consumed by the comprehensive utilization of tail gas, and the
construction of projects such as infrastructure and technical transformation.
6.1.2.2 When sharing auxiliary and/or subsidiary production systems outside the
boundary with other facilities, the energy consumed and lost by the carbon black
facilities shall be apportioned according to the physical energy consumption.
6.1.2.3 The waste heat and waste energy recycled within the boundary area shall not be
included in the energy consumption if used within the boundary area; if used outside
the boundary area, it shall be deducted from the energy consumption according to the
actual external supply.
6.1.2.4 The carbon black output is the total mass of all qualified carbon black products
produced by the facilities during the statistical reporting period.
6.1.2.5 During the statistical reporting period, the calorific value of various energy shall
be measured according to the method specified in GB/T 384 or GB/T 12206 and
converted into coal equivalent. If there are no actual measurement conditions, the coal
equivalent conversion coefficient of energy and energy-consuming medium given in
Annex B and Annex C can be referred to.
6.2 Calculation methods
6.2.1 Comprehensive energy consumption of tyre
The comprehensive energy consumption of tyre is calculated according to formula (1).
