Introduction
Core changes in the standard revision
| Comparison dimensions | 2010 series of standards | 2023 new standards |
|---|---|---|
| Standard structure | 7 sub-standards | Integrated into a single standard |
| Definition of terms | Quote GB/T 2900.18 | Add 6 core definitions including Environmentally aware design |
| Technical requirements | Focus on the introduction of environmental factors | Strengthen class=instrument>Life cycle thinking and system integration |
Core principles of environmentally conscious design
4.1 Life cycle thinking
The standard requires that the environmental impact of the entire life cycle of the product be considered during the design phase, with a focus on:
- Material acquisition phase: Limit the use of hazardous substances such as lead and mercury
- Manufacturing process: Optimize energy consumption ratio (recommended to reduce 15-20%)
- Use phase: Improve the energy efficiency of products such as circuit breakers
- Scrap disposal: Modular design facilitates disassembly and recycling
4.2 Management system integration
It is recommended that enterprises incorporate environmental design into the existing management system, with special emphasis on:
Example: After a contactor manufacturer passed ISO14001 certification, the material recycling rate of its products increased to 92%
Key Technology Implementation Points
6.3.1 Material Selection Specifications
| Material Type | Restriction Requirements | Alternative Solutions |
|---|---|---|
| Contact Materials | Banned Lead-Tin Alloy | Silver Tin Oxide (AgSnO₂) |
| Plastic Products | Phthalates ≤0.1% | Bio-based Plasticizers |
6.3.2 Production Process Optimization
The standard specifically points out that the electroplating process should:
- Eliminate the hexavalent chromium passivation process
- Adopt cyanide-free electroplating technology
- Establish an online wastewater monitoring system
Implementation Recommendations
- Establish a material database: Include a list of more than 300 restricted substances
- Conduct LCA evaluation: It is recommended to use professional tools such as SimaPro
- Supply chain collaboration: Require suppliers to provide material declaration forms
Typical product design case
Fuse products use copper-plated silver to replace lead-tin alloy, reducing the use of lead by 23.5kg per 10,000 products
