If a company develops in a benign way, then it will certainly receive social and industry recognition. In order to quantify this recognition, there are three major corporate certifications, ISO9001, ISO14001, OHSAS18001.
However, due to strict certification standards, many companies have only obtained one or not, and ZTELEC GROUP has already obtained three.

ISO 9001 has been transformed from the world's first quality management system standard, BS 5750 (BSI). ISO 9001 is by far the most mature quality framework in the world, and more than 750,000 organizations in 161 countries around the world are working to use this framework. ISO 9001 sets standards not only for the quality management system but also for the entire management system. It helps organizations succeed by improving customer satisfaction, employee motivation and continuous improvement.
ISO14001 certification applies to any organization, including corporations, corporations and related government agencies. Once certified, the organization can demonstrate that the organization has met international standards for environmental management and ensures that all types of contaminants in the company's processes, products, and activities are controlled. Relevant requirements will help companies to establish a good social image.

The OHSAS 18000 series of standards is an international standard jointly launched by 13 organizations including the British Standards Institute (BSI) and the Norwegian Classification Society (DNV) in 1999. When the ISO has not yet been released, it has played a role in quasi-international standards. Founded. The OHSAS18001 standard is the certification standard. It is the basis for establishing an occupational health and safety management system for organizations (enterprises) and the main basis for companies to conduct certification audits through internal audit and certification bodies.
