ISO 9001

ISO 9001 provides standardized requirements for a best-in-class quality management system, regardless of what the organization does or its size.
The ISO 9001 standard provides a proven framework for managing quality that will lead to producing consistently higher-quality products. ISO 9001, as well as other ISO standards, have been developed by the International Organization for Standardization (ISO), the world’s largest developer and publisher of international standards.

ISO 14001

An EMS that meets the ISO 14001 requirements provides management tools necessary to:
- identify and control the environmental impact of a company’s activities, products or services;
- continually improve environmental performance; and
- implement a systematic approach to setting environmental objectives and targets, achieve those targets, and demonstrate that those targets have been achieved.

2. JISHA OSHMS (Occupational Safety and Health Management Systems)

JISHA OSHMS standards were established by the Japan Industrial Safety and Health Association (JISHA) and they conform to the Guidelines for OSHMS’s from the Ministry of Health, Labor and Welfare of Japan. These standards are adapted for actual safety and health management situations as well as specific safety and health activities at Japanese companies.
