above all, it is its strict application that has allowed us to obtain the recognition of an independent organization: The International Accreditation Forum (IAF). The quality system for the design and manufacturing of TGOOD products is certified to be in conformity with the requirements of ISO 9001: 2015 quality assurance standard.

Strict and Systematic ChecksDuring manufacturing, each product functional unit is subject to systematic routine testing with the aim of checking the quality and conformity of the related features. The results obtained are recorded and approved by the quality control department on each product’s test certificate. This guarantees product traceability.

Environment ProtectionAs part of the group’s environmental policy, TGOOD provides you an option to recover the products and thus eliminate any discharge to theatmosphere. In order to help you protect the environment and to relieve you of any concerns in terms of stock or dismantling, the TGOOD service offers to take back your equipment at the end of its lifetime. The products have been designed with environmental protection in mind:• All materials used are identified, and easily separable for recycling• SF6 usage is reduced in GIS, and can be recovered at the end

of the equipment’s life• Production sites are certified to ISO 14001

Occupational Health and SafetyOccupational Health and Safety (OH&S) bears highest importance at TGOOD. TGOOD demonstrates its commitment towards control of risks and improvement in performance of OH&S by complying to OHSAS 18001:2007 certified by the China National Accreditation Service (CNAS). The TGOOD management believes in process approach and its policy is based on the PDCA methodology. This focuses on elimination or minimizing risks to personnel and other interested parties who could be exposed to OH&S hazards associated with its activities. Strong mechanisms are in place to assure that TGOOD`s performance on OH&S is not only met, but also exceeds its legal and policy requirements.
