GB29438-2012
The norm of energy consumption per unit product of polyoxymethylene
聚甲醛单位产品能源消耗限额
GB 29438-2012 is a current mandatory Chinese national standard for The norm of energy consumption per unit product of polyoxymethylene. It appears in the Construction compliance cluster with a energy efficiency focus and has an implementation date of Oct 1, 2013.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to the calculation and assessment of energy consumption for polyoxymethylene production enterprises using methanol and ethylene glycol as main raw materials. It also covers energy consumption control for new construction or expansion projects. It is mandatory for all existing and new polyoxymethylene manufacturers in China. The standard does not apply to production processes using alternative raw materials.
Technical requirements
The standard establishes mandatory energy consumption limits for polyoxymethylene production, categorized into three tiers: existing facilities, new or expanded facilities, and advanced values. For existing facilities, the energy consumption limit must not exceed a specified threshold. For new or expanded facilities, a stricter access value is enforced to ensure higher energy efficiency. The standard also encourages enterprises to achieve an advanced value through technical retrofits and management improvements. Compliance with these specific kgce/t limits is strictly enforced for market access. Additionally, it references various energy efficiency standards such as GB 17167 for energy metering and GB 18613 for motor efficiency.
Testing methods
The standard outlines the statistical scope and calculation methods for comprehensive energy consumption. It includes the calculation of total energy input minus energy output, converted to a unified unit of kilograms of standard coal equivalent (kgce). The unit product energy consumption is calculated by dividing the total comprehensive energy consumption by the total polyoxymethylene output during the reporting period. Accurate statistical accounting across all production stages is required for compliance. Reference coefficients for various energy types and energy-consuming working fluids are provided in the appendices.
FAQs
What products are regulated under GB 29438-2012?
It regulates polyoxymethylene products manufactured using methanol and ethylene glycol as primary raw materials.
Are the energy consumption limits mandatory?
Yes, the limits for existing facilities (4.1) and new/expanded facilities (4.2) are mandatory, while the advanced value (4.3) is recommended.
What is the unit of measurement for energy consumption in this standard?
The energy consumption is measured in kilograms of standard coal equivalent per ton (kgce/t) of polyoxymethylene product.
