Introduction

Any product can have an environmental impact, and its effects may occur throughout the life of the product or at any one of its phases, such as the original Materials procurement, manufacturing, sales, use and disposal. These effects may be slight or significant; they may be short-term or possible is long-term; may occur locally, regionally or globally (or combinations thereof).

Customers, users, developers and other stakeholders are increasingly concerned about the impact of environmental factors and products.

Predicting or identifying the environmental aspects of a product over its life cycle can be complicated. The environmental factors of the product also need to be weighed against the others Factors such as intended use, performance, safety and health, cost, marketability, product quality and regulatory requirements. For use in the system the product is very important considering its use function.

The process of integrating environmental factors into product design and development requires continuity and flexibility, encouraging creativity and improving the environment Innovation and opportunity maximization. Environmental issues should be incorporated into the policies and strategies of relevant organizations.

Early identification and planning enable organizations to make effective decisions about the environmental factors that they control. Helps to understand them better How the decisions affect the environmental aspects that are governed by other organizations, such as the acquisition of raw materials and components or the end of life.

The purpose of this standard is to help product designers in the areas of audio, video, information technology and communications technology in the design of their products when managing the related environmental issues.

Specific documents in this area take into account the publication of the second edition of ECMA-341 (2004), the latest engineering best practices, the current market and product environmental regulations.

Audio, video, information technology and communications technology equipment Environmental awareness design

1 Scope

This standard applies to all "audio, video, information technology and communications technology equipment," the final product, hereinafter referred to as "products." Although this standard does not explicitly apply to the components and components of the final product, component manufacturers also need to consider this standard to ensure Manufacturers to use these components to produce products to meet the requirements of this standard.

The scope of this standard is limited to the manufacturer's intended use of the product.

This standard specifies the requirements and recommendations for the design of environmentally sound products from the following aspects.

--- life cycle thinking;

--- Material efficiency;

---efficiency;

--- Consumables and batteries;

--- Chemical and noise emission;

--- Product life extension;

--- End of life;

--- harmful substances and harmful products;

---Product packaging.

This standard only relates directly to product environmental performance criteria. Such as product safety, ergonomics and electromagnetic compatibility (EMC) not within the scope of this standard by other standards.
