PROMOTION OF ENVIRONMENTAL MANAGEMENT SYSTEM

CONFORMING TO INTERNATIONAL STANDARDS

At Seiko Epson, all environmental initiatives operate under the

Plan-Do-Check-Action (PDCA) cycle designed to achieve continuous

improvements. The environmental management system (EMS)

operates under the ISO 14001 environmental management standard.

All of our major manufacturing and non-manufacturing sites, in

Japan and overseas, completed the acquisition of ISO 14001

certification.

ISO 14000 is an international standard for environmental

management that was established by the International

Standards Organization in 1996 against the background of

growing concern regarding global warming, destruction of

the ozone layer, and global deforestation.

WORKING FOR HIGH QUALITY

In order provide high quality and reliable products and services

than meet customer needs,

Seiko Epson made early efforts towards obtaining ISO9000 series

certification and has acquired ISO9001 for all business

establishments in Japan and abroad. We have also acquired ISO/TS

16949 certification that is requested strongly by major automotive

manufacturers as standard.

►Explanation

of the mark that are using it for the catalog

►Pb

free.

►Complies

with EU RoHS directive.

*About the products without the Pb-free mark.

Contains Pb in products exempted by EU RoHS directive.

(Contains Pb in sealing glass, high melting temperature type solder or other.)

►Designed

for automotive applications such as Car Multimedia, Body Electronics, Remote Keyless Entry etc.

►Designed

for automotive applications related to driving safety (Engine Control Unit, Air Bag, ESC etc ).

ISO/TS16949 is the international standard that added the

sector-specific supplemental requirements for automotive

industry based on ISO9001.
