Introduction
Overcurrent protection circuit breaker in household and similar installation, as overload and short-circuit protection appliance in terminal circuit, is widely used in low-voltage apparatus. With the continuous development of modern science and technology, new technologies, new processes and new materials are constantly appearing, and the production process and various materials of circuit-breakers for overcurrent protection are constantly improved, which greatly improves the performance of circuit-breakers for overcurrent protection in household and similar installation.
Green-design products are the ultimate embodiment of supply-side structural reform through green manufacturing, focusing on the greening of the whole life cycle of products. It is helpful to minimize energy and resource consumption and ecological environment impact and maximize regeneration rate by actively carrying out green-design and taking the impacts of raw material selection, production, sale, use, recovery and disposal on resources and environment in the product design and development stage according to the concept of the whole life cycle.
This standard specifies the assessment principles and methods, organizational requirements, assessment indicators, assessment method for product life cycle and requirements of report format for green-design products of circuit-breakers for overcurrent protection in household and similar installation.
The main contents of this standard are as follows:
——The applicable scope of standards and normative references are specified;
——The terms and definitions of product green-design are specified;
——The assessment principles, methods and basis of product green-design are specified;
——The assessment indicator requirements of product green-design are specified.
Before the formulation of this standard, the assessment of green-design products of circuit-breakers for overcurrent protection in household and similar installation has been in a situation where there is no standard to follow, resulting in difference of manufacturers in green-design products and their environmental friendliness. The formulation of this standard enables all parties concerned to seriously study and discuss the green-design products of circuit-breakers for overcurrent protection, and improve the environmental protection awareness of all production enterprises. In addition, it provides basis for energy resources, ecological environment impact and regeneration rate of products. Main issues concerned in the standard are to:
——specify category and contents of hazardous substances restricted in products;
——specify the calculation method and indicator of recyclability rate of product;
——specify the operating life of products, which is higher than the current national standard by reference to the upper-middle level in the industry and the feedback from the participating units;
——specify the maximum power consumption index of products per pole, which is higher than the current national standard by reference to the upper-middle level in the industry.
This standard is formulated in combination with the current energy-saving requirements, which helps to improve the whole industry's attention to the environmental friendliness of products, establish the green image of domestic brands and made-in-China products, and create good social benefits.
