Introduction

For the benefit of the future, people are paying more and more attention to protecting the natural environment. To achieve this goal, it is necessary to

The efficient use of energy and materials within the life cycle should be adopted to protect the world's limited natural resources. In addition, it is advisable to avoid or minimize the use of materials that may have a negative impact on the environment.

Substances and materials that are harmful or cause climate change. From product conception to the end of its service life, the environmental impact of all relevant processes should be considered, including

including how to dispose of or recycle the material for recycling.

In order to protect natural resources, manufacturers of low-voltage switchgear and controlgear and their assemblies should ensure environmentally conscious design.

(ECD), including.

--- Gradually eliminate or minimize the use of hazardous substances or materials;

---Efficient use of energy and materials in product manufacturing;

--- Ensure that the actual energy consumption of the product during use is the lowest;

---At the end of product life, recycle materials for future use as much as possible and sort hazardous components that require special handling.

There is an increasing number of products that require declarations and environmentally conscious design, and in some cases it is mandatory.

It can take many forms, for example, Type II or Type III environmental declaration, material declaration (MD). In some companies, Green Public Procurement (GPP) is applicable.

ECD is part of ISO 14001 certification. Some countries and regions are also actively promoting environmental protection, such as the EU's Ecodesign

Directive, China's eco-design initiative. In the medium term, most customers have a demand for systematic ECD.

Assessing the environmental impact of low voltage switchgear and controlgear and their assemblies is part of the ECD process. ECD requires identification,

Measuring and reporting specific impacts. IEC 62430 describes the basic principles of ECD, which aims to reduce the potential impact of products on the environment.

Generally, the impact of low-voltage switchgear and control equipment and their complete sets on the environment is related to the entire system to which they belong and the

Processes such as air conditioning of buildings, steel manufacturing or shipping have a far greater impact on lifetime than any associated low pressure

Manufacture and use of switchgear and controlgear.

Although low voltage switchgear and control equipment and their complete equipment have relatively small impact on the environment, the market still needs appropriate methods to

Simplified methods for estimating environmental impacts and readily available data are used to enable stakeholders (such as contractors,

It is easier for installers and end users to assess system-level environmental impacts.

The purpose of this document is to provide specific rules for assessing the environmental impact and providing appropriate data for low-voltage switchgear and controlgear and their assemblies.

These rules establish a common

environmental impact assessment programme.

1 Scope

This document provides manufacturers of low voltage switchgear and controlgear and their complete equipment with the ability to assess and improve the environmental impact of their products.

Guidance for the effective communication of common environmental information throughout the supply chain.

This document provides.

---Guidelines for the process and general requirements for implementing environmentally aware product design principles as specified in IEC 62430, which are applicable to low-voltage switchgear

Equipment and control equipment and their complete sets are crucial;

--- Product Specific Rules (PSR) for Life Cycle Assessment (LCA);

Note 1.The general methods and processes for performing LCA comply with the requirements of ISO 14044 and GB/T 24040, but this document does not describe these methods and processes.

NOTE 2 PSR and LCA can be used for quantitative ECD and also for certain environmental claims, such as Type III.

--- Standard environmental impact data obtained from case studies and their use;

NOTE 3 This is to encourage manufacturers to apply more effective quantitative methods in the ECD process to improve the environmental efficiency of their products.

--- General rules for restricted substances and information on materials contained in products according to IEC 62474;

---Guidelines for product end-of-life processing information.

NOTE 4 This document is intended to replace Annex O and Annex W in IEC 60947-1.2020.
